Detailed Description

A Gdk::Window is a rectangular region on the screen. It's a low-level object, used to implement high-level objects such as Gtk::Widget and Gtk::Window on the GTK+ level. A Gtk::Window is a toplevel window, the thing a user might think of as a "window" with a titlebar and so on; a Gtk::Window may contain many Gdk::Windows. For example, each Gtk::Button has a Gdk::Window associated with it.

Member Function Documentation

◆ add_filter()

void Gdk::Window::add_filter	(	GdkFilterFunc	function,
		gpointer	data
	)

Adds an event filter to window, allowing you to intercept events before they reach GDK. This is a low-level operation and makes it easy to break GDK and/or GTK+, so you have to know what you're doing. Pass 0 for window to get all events for all windows, instead of events for a specific window.

See Gdk::Display::add_client_message_filter() if you are interested in X ClientMessage events.

Parameters

function	Filter callback.
data	Data to pass to filter callback.

◆ beep()

void Gdk::Window::beep ( )

Emits a short beep associated to window in the appropriate display, if supported. Otherwise, emits a short beep on the display just as Gdk::Display::beep().

◆ begin_move_drag()

void Gdk::Window::begin_move_drag	(	int	button,
		int	root_x,
		int	root_y,
		guint32	timestamp
	)

Begins a window move operation (for a toplevel window). You might use this function to implement a "window move grip," for example. The function works best with window managers that support the Extended Window Manager Hints, but has a fallback implementation for other window managers.

Parameters

button	The button being used to drag.
root_x	Root window X coordinate of mouse click that began the drag.
root_y	Root window Y coordinate of mouse click that began the drag.
timestamp	Timestamp of mouse click that began the drag.

◆ begin_paint_rect()

void Gdk::Window::begin_paint_rect ( Rectangle & rectangle )

A convenience wrapper around begin_paint_region() which creates a rectangular region for you. See begin_paint_region() for details.

Parameters

rectangle Rectangle you intend to draw to.

◆ begin_paint_region()

void Gdk::Window::begin_paint_region ( const Region & region )

Indicates that you are beginning the process of redrawing region. A backing store (offscreen buffer) large enough to contain region will be created. The backing store will be initialized with the background color or background pixmap for window. Then, all drawing operations performed on window will be diverted to the backing store. When you call end_paint(), the backing store will be copied to window, making it visible onscreen. Only the part of window contained in region will be modified; that is, drawing operations are clipped to region.

The net result of all this is to remove flicker, because the user sees the finished product appear all at once when you call end_paint(). If you draw to window directly without calling begin_paint_region(), the user may see flicker as individual drawing operations are performed in sequence. The clipping and background-initializing features of begin_paint_region() are conveniences for the programmer, so you can avoid doing that work yourself.

When using GTK+, the widget system automatically places calls to begin_paint_region() and end_paint() around emissions of the expose_event signal. That is, if you're writing an expose event handler, you can assume that the exposed area in Gdk::EventExpose has already been cleared to the window background, is already set as the clip region, and already has a backing store. Therefore in most cases, application code need not call begin_paint_region(). (You can disable the automatic calls around expose events on a widget-by-widget basis by calling gtk_widget_set_double_buffered().)

If you call this function multiple times before calling the matching end_paint(), the backing stores are pushed onto a stack. end_paint() copies the topmost backing store onscreen, subtracts the topmost region from all other regions in the stack, and pops the stack. All drawing operations affect only the topmost backing store in the stack. One matching call to end_paint() is required for each call to begin_paint_region().

Parameters

region Region you intend to draw to.

◆ begin_resize_drag()

void Gdk::Window::begin_resize_drag	(	WindowEdge	edge,
		int	button,
		int	root_x,
		int	root_y,
		guint32	timestamp
	)

Begins a window resize operation (for a toplevel window). You might use this function to implement a "window resize grip," for example; in fact Gtk::Statusbar uses it. The function works best with window managers that support the Extended Window Manager Hints, but has a fallback implementation for other window managers.

Parameters

edge	The edge or corner from which the drag is started.
button	The button being used to drag.
root_x	Root window X coordinate of mouse click that began the drag.
root_y	Root window Y coordinate of mouse click that began the drag.
timestamp	Timestamp of mouse click that began the drag (use Gdk::Event::get_time()).

◆ clear()

void Gdk::Window::clear ( )

Clears an entire window to the background color or background pixmap.

◆ clear_area()

void Gdk::Window::clear_area	(	int	x,
		int	y,
		int	width,
		int	height
	)

Clears an area of window to the background color or background pixmap.

Parameters

x	X coordinate of rectangle to clear.
y	Y coordinate of rectangle to clear.
width	Width of rectangle to clear.
height	Height of rectangle to clear.

◆ clear_area_e()

void Gdk::Window::clear_area_e	(	int	x,
		int	y,
		int	width,
		int	height
	)

Like clear_area(), but also generates an expose event for the cleared area.

This function has a stupid name because it dates back to the mists time, pre-GDK-1.0.

Parameters

x	X coordinate of rectangle to clear.
y	Y coordinate of rectangle to clear.
width	Width of rectangle to clear.
height	Height of rectangle to clear.

◆ configure_finished()

void Gdk::Window::configure_finished ( )

Signal to the window system that the application has finished handling Configure events it has received. Window Managers can use this to better synchronize the frame repaint with the application. GTK+ applications will automatically call this function when appropriate.

This function can only be called if enable_synchronized_configure() was called previously.

◆ constrain_size()

static void Gdk::Window::constrain_size	(	const Geometry &	geometry,
		guint	flags,
		int	width,
		int	height,
		int &	new_width,
		int &	new_height
	)

static

Constrains a desired width and height according to a set of geometry hints (such as minimum and maximum size).

Parameters

geometry	A Gdk::Geometry structure.
flags	A mask indicating what portions of geometry are set.
width	Desired width of window.
height	Desired height of the window.
new_width	Location to store resulting width.
new_height	Location to store resulting height.

◆ coords_from_parent()

void Gdk::Window::coords_from_parent	(	double	parent_x,
		double	parent_y,
		double &	x,
		double &	y
	)

Transforms window coordinates from a parent window to a child window, where the parent window is the normal parent as returned by get_parent() for normal windows, and the window's embedder as returned by gdk_offscreen_window_get_embedder() for offscreen windows.

For normal windows, calling this function is equivalent to subtracting the return values of get_position() from the parent coordinates. For offscreen windows however (which can be arbitrarily transformed), this function calls the GdkWindow::from-embedder: signal to translate the coordinates.

You should always use this function when writing generic code that walks down a window hierarchy.

◆ coords_to_parent()

void Gdk::Window::coords_to_parent	(	double	x,
		double	y,
		double &	parent_x,
		double &	parent_y
	)

Transforms window coordinates from a child window to its parent window, where the parent window is the normal parent as returned by get_parent() for normal windows, and the window's embedder as returned by gdk_offscreen_window_get_embedder() for offscreen windows.

For normal windows, calling this function is equivalent to adding the return values of get_position() to the child coordinates. For offscreen windows however (which can be arbitrarily transformed), this function calls the GdkWindow::to-embedder: signal to translate the coordinates.

You should always use this function when writing generic code that walks up a window hierarchy.

◆ create()

static Glib::RefPtr<Window> Gdk::Window::create	(	const Glib::RefPtr< Window > &	parent,
		GdkWindowAttr *	attributes,
		int	attributes_mask
	)

static

◆ create_similar_surface()

::Cairo::RefPtr< ::Cairo::Surface> Gdk::Window::create_similar_surface	(	::Cairo::Content	content,
		int	width,
		int	height
	)

Create a new surface that is as compatible as possible with the given window. For example the new surface will have the same fallback resolution and font options as window. Generally, the new surface will also use the same backend as window, unless that is not possible for some reason. The type of the returned surface may be examined with cairo_surface_get_type().

Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.)

Parameters

content	The content for the new surface.
width	Width of the new surface.
height	Height of the new surface.

Returns: A pointer to the newly allocated surface. The caller owns the surface and should call cairo_surface_destroy() when done with it.

This function always returns a valid pointer, but it will return a pointer to a "nil" surface if other is already in an error state or any other error occurs.

◆ deiconify()

void Gdk::Window::deiconify ( )

Attempt to deiconify (unminimize) window. On X11 the window manager may choose to ignore the request to deiconify. When using GTK+, use gtk_window_deiconify() instead of the Gdk::Window variant. Or better yet, you probably want to use gtk_window_present(), which raises the window, focuses it, unminimizes it, and puts it on the current desktop.

◆ drag_begin()

Glib::RefPtr<DragContext> Gdk::Window::drag_begin ( const Glib::StringArrayHandle & targets )

Starts a drag and creates a new drag context for it.

This method is called by the drag source.

Parameters

targets A list of the offered targets names.

Returns: A newly created Gdk::DragContext.

◆ enable_synchronized_configure()

void Gdk::Window::enable_synchronized_configure ( )

Indicates that the application will cooperate with the window system in synchronizing the window repaint with the window manager during resizing operations. After an application calls this function, it must call configure_finished() every time it has finished all processing associated with a set of Configure events. Toplevel GTK+ windows automatically use this protocol.

On X, calling this function makes window participate in the _NET_WM_SYNC_REQUEST window manager protocol.

◆ end_paint()

void Gdk::Window::end_paint ( )

Indicates that the backing store created by the most recent call to begin_paint_region() should be copied onscreen and deleted, leaving the next-most-recent backing store or no backing store at all as the active paint region. See begin_paint_region() for full details. It is an error to call this function without a matching begin_paint_region() first.

◆ ensure_native()

bool Gdk::Window::ensure_native ( )

Tries to ensure that there is a window-system native window for this GdkWindow. This may fail in some situations, returning false.

Offscreen window and children of them can never have native windows.

Some backends may not support native child windows.

Returns: true if the window has a native window, false otherwise.

◆ flush()

void Gdk::Window::flush ( )

Flush all outstanding cached operations on a window, leaving the window in a state which reflects all that has been drawn before.

Gdk uses multiple kinds of caching to get better performance and nicer drawing. For instance, during exposes all paints to a window using double buffered rendering are keep on a pixmap until the last window has been exposed. It also delays window moves/scrolls until as long as possible until next update to avoid tearing when moving windows.

Normally this should be completely invisible to applications, as we automatically flush the windows when required, but this might be needed if you for instance mix direct native drawing with gdk drawing. For Gtk widgets that don't use double buffering this will be called automatically before sending the expose event.

◆ focus()

void Gdk::Window::focus ( guint32 timestamp )

Sets keyboard focus to window. In most cases, gtk_window_present() should be used on a Gtk::Window, rather than calling this function.

Parameters

timestamp Timestamp of the event triggering the window focus.

◆ freeze_updates()

void Gdk::Window::freeze_updates ( )

Temporarily freezes a window such that it won't receive expose events. The window will begin receiving expose events again when Gdk::Window::thaw_updates() is called. If Gdk::Window::freeze_updates() has been called more than once, Gdk::Window::thaw_updates() must be called an equal number of times to begin processing exposes.

◆ fullscreen()

void Gdk::Window::fullscreen ( )

Moves the window into fullscreen mode. This means the window covers the entire screen and is above any panels or task bars.

If the window was already fullscreen, then this function does nothing.

On X11, asks the window manager to put window in a fullscreen state, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don't have a concept of "fullscreen"; so you can't rely on the fullscreenification actually happening. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

◆ geometry_changed()

void Gdk::Window::geometry_changed ( )

This function informs GDK that the geometry of an embedded offscreen window has changed. This is necessary for GDK to keep track of which offscreen window the pointer is in.

◆ get_accept_focus()

bool Gdk::Window::get_accept_focus ( ) const

Determines whether or not the desktop environment shuld be hinted that the window does not want to receive input focus.

Returns: Whether or not the window should receive input focus.

◆ get_background_pattern() [1/2]

::Cairo::RefPtr< ::Cairo::Pattern> Gdk::Window::get_background_pattern ( )

Gets the pattern used to clear the background on window. If window does not have its own background and reuses the parent's, 0 is returned and you'll have to query it yourself.

◆ get_children() [1/2]

Glib::ListHandle< Glib::RefPtr<Window> > Gdk::Window::get_children ( )

Gets the list of children of window known to GDK. This function only returns children created via GDK, so for example it's useless when used with the root window; it only returns windows an application created itself.

The returned list must be freed, but the elements in the list need not be.

Returns: List of child windows inside window.

◆ get_children() [2/2]

Glib::ListHandle< Glib::RefPtr<const Window> > Gdk::Window::get_children ( ) const

Gets the list of children of window known to GDK. This function only returns children created via GDK, so for example it's useless when used with the root window; it only returns windows an application created itself.

The returned list must be freed, but the elements in the list need not be.

Returns: List of child windows inside window.

◆ get_composited()

bool Gdk::Window::get_composited ( ) const

Determines whether window is composited.

See set_composited().

Returns: true if the window is composited.

◆ get_decorations()

bool Gdk::Window::get_decorations ( WMDecoration & decorations ) const

Returns the decorations set on the GdkWindow with gdk_window_set_decorations

Parameters

decorations The window decorations will be written here.

Returns: The Gdk::Display associated with window.

◆ get_effective_parent() [1/2]

Glib::RefPtr<Window> Gdk::Window::get_effective_parent ( )

Obtains the parent of window, as known to GDK. Works like get_parent() for normal windows, but returns the window's embedder for offscreen windows.

Returns: Effective parent of window.

◆ get_effective_parent() [2/2]

Glib::RefPtr<const Window> Gdk::Window::get_effective_parent ( ) const

Obtains the parent of window, as known to GDK. Works like get_parent() for normal windows, but returns the window's embedder for offscreen windows.

Returns: Effective parent of window.

◆ get_effective_toplevel()

Glib::RefPtr<Window> Gdk::Window::get_effective_toplevel ( )

Gets the toplevel window that's an ancestor of window.

Works like get_toplevel(), but treats an offscreen window's embedder as its parent, using get_effective_parent().

Returns: The effective toplevel window containing window.

◆ get_events()

EventMask Gdk::Window::get_events ( ) const

Gets the event mask for window. See set_events().

Returns: Event mask for window.

◆ get_focus_on_map()

bool Gdk::Window::get_focus_on_map ( ) const

Determines whether or not the desktop environment should be hinted that the window does not want to receive input focus when it is mapped.

Returns: Whether or not the window wants to receive input focus when it is mapped.

◆ get_frame_extents()

void Gdk::Window::get_frame_extents ( Rectangle & rect )

Obtains the bounding box of the window, including window manager titlebar/borders if any. The frame position is given in root window coordinates. To get the position of the window itself (rather than the frame) in root window coordinates, use get_origin().

Parameters

rect	Rectangle to fill with bounding box of the window frame.

◆ get_geometry()

void Gdk::Window::get_geometry	(	int &	x,
		int &	y,
		int &	width,
		int &	height,
		int &	depth
	)		const

Any of the return location arguments to this function may be 0, if you aren't interested in getting the value of that field.

The X and Y coordinates returned are relative to the parent window of window, which for toplevels usually means relative to the window decorations (titlebar, etc.) rather than relative to the root window (screen-size background window).

On the X11 platform, the geometry is obtained from the X server, so reflects the latest position of window; this may be out-of-sync with the position of window delivered in the most-recently-processed Gdk::EventConfigure. get_position() in contrast gets the position from the most recent configure event.

Note: If window is not a toplevel, it is much better to call get_position() and Gdk::Drawable::get_size() instead, because it avoids the roundtrip to the X server and because Gdk::Drawable::get_size() supports the full 32-bit coordinate space, whereas get_geometry() is restricted to the 16-bit coordinates of X11.

Parameters

x	Return location for X coordinate of window (relative to its parent).
y	Return location for Y coordinate of window (relative to its parent).
width	Return location for width of window.
height	Return location for height of window.
depth	Return location for bit depth of window.

◆ get_group() [1/2]

Glib::RefPtr<Window> Gdk::Window::get_group ( )

Returns the group leader window for window. See set_group().

Returns: The group leader window for window.

◆ get_group() [2/2]

Glib::RefPtr<const Window> Gdk::Window::get_group ( ) const

Returns the group leader window for window. See set_group().

Returns: The group leader window for window.

◆ get_height()

int Gdk::Window::get_height ( ) const

Returns the height of the given window.

On the X11 platform the returned size is the size reported in the most-recently-processed configure event, rather than the current size on the X server.

Returns: The height of window.

◆ get_internal_paint_info()

void Gdk::Window::get_internal_paint_info	(	Glib::RefPtr< Drawable > &	real_drawable,
		int &	x_offset,
		int &	y_offset
	)		const

◆ get_modal_hint()

bool Gdk::Window::get_modal_hint ( ) const

Determines whether or not the window manager is hinted that window has modal behaviour.

Returns: Whether or not the window has the modal hint set.

◆ get_offscreen_embedder() [1/2]

Glib::RefPtr<Window> Gdk::Window::get_offscreen_embedder ( )

Gets the window that window is embedded in.

Parameters

◆ get_offscreen_embedder() [2/2]

Glib::RefPtr<const Window> Gdk::Window::get_offscreen_embedder ( ) const

Gets the window that window is embedded in.

Parameters

window A Gdk::Window.

Returns: The embedding Gdk::Window, or 0 if window is not an embedded offscreen window.

◆ get_offscreen_pixmap() [1/2]

Glib::RefPtr<Pixmap> Gdk::Window::get_offscreen_pixmap ( )

Gets the offscreen pixmap that an offscreen window renders into. If you need to keep this around over window resizes, you need to add a reference to it.

Parameters

window A Gdk::Window.

Returns: The offscreen pixmap, or 0 if not offscreen.

◆ get_offscreen_pixmap() [2/2]

Glib::RefPtr<const Pixmap> Gdk::Window::get_offscreen_pixmap ( ) const

Gets the offscreen pixmap that an offscreen window renders into. If you need to keep this around over window resizes, you need to add a reference to it.

Parameters

window A Gdk::Window.

Returns: The offscreen pixmap, or 0 if not offscreen.

◆ get_origin()

int Gdk::Window::get_origin	(	int &	x,
		int &	y
	)		const

Obtains the position of a window in root window coordinates. (Compare with get_position() and get_geometry() which return the position of a window relative to its parent window.)

Parameters

x	Return location for X coordinate.
y	Return location for Y coordinate.

Returns: Not meaningful, ignore.

◆ get_parent() [1/2]

Glib::RefPtr<Window> Gdk::Window::get_parent ( )

Obtains the parent of window, as known to GDK. Does not query the X server; thus this returns the parent as passed to new(), not the actual parent. This should never matter unless you're using Xlib calls mixed with GDK calls on the X11 platform. It may also matter for toplevel windows, because the window manager may choose to reparent them.

Note that you should use get_effective_parent() when writing generic code that walks up a window hierarchy, because get_parent() will most likely not do what you expect if there are offscreen windows in the hierarchy.

Returns: Parent of window.

◆ get_parent() [2/2]

Glib::RefPtr<const Window> Gdk::Window::get_parent ( ) const

Obtains the parent of window, as known to GDK. Does not query the X server; thus this returns the parent as passed to new(), not the actual parent. This should never matter unless you're using Xlib calls mixed with GDK calls on the X11 platform. It may also matter for toplevel windows, because the window manager may choose to reparent them.

Note that you should use get_effective_parent() when writing generic code that walks up a window hierarchy, because get_parent() will most likely not do what you expect if there are offscreen windows in the hierarchy.

Returns: Parent of window.

◆ get_pointer()

Glib::RefPtr<Window> Gdk::Window::get_pointer	(	int &	x,
		int &	y,
		ModifierType &	mask
	)

Obtains the current pointer position and modifier state. The position is given in coordinates relative to the upper left corner of window.

Parameters

x	Return location for X coordinate of pointer or `0` to not return the X coordinate.
y	Return location for Y coordinate of pointer or `0` to not return the Y coordinate.
mask	Return location for modifier mask or `0` to not return the modifier mask.

Returns: The window containing the pointer (as with at_pointer()), or 0 if the window containing the pointer isn't known to GDK.

◆ get_position()

void Gdk::Window::get_position	(	int &	x,
		int &	y
	)		const

Obtains the position of the window as reported in the most-recently-processed Gdk::EventConfigure. Contrast with get_geometry() which queries the X server for the current window position, regardless of which events have been received or processed.

The position coordinates are relative to the window's parent window.

Parameters

x	X coordinate of window.
y	Y coordinate of window.

◆ get_root_coords()

void Gdk::Window::get_root_coords	(	int	x,
		int	y,
		int &	root_x,
		int &	root_y
	)

Obtains the position of a window position in root window coordinates. This is similar to get_origin() but allows you go pass in any position in the window, not just the origin.

Parameters

x	X coordinate in window.
y	Y coordinate in window.
root_x	Return location for X coordinate.
root_y	Return location for Y coordinate.

◆ get_root_origin()

void Gdk::Window::get_root_origin	(	int &	x,
		int &	y
	)		const

Returns: The Gdk::Screen associated with window.

◆ get_state()

WindowState Gdk::Window::get_state ( ) const

Gets the bitwise OR of the currently active window state flags, from the Gdk::WindowState enumeration.

Returns: Window state bitfield.

◆ get_toplevel() [1/2]

Glib::RefPtr<Window> Gdk::Window::get_toplevel ( )

Gets the toplevel window that's an ancestor of window.

Any window type but Gdk::WINDOW_CHILD is considered a toplevel window, as is a Gdk::WINDOW_CHILD window that has a root window as parent.

Note that you should use get_effective_toplevel() when you want to get to a window's toplevel as seen on screen, because get_toplevel() will most likely not do what you expect if there are offscreen windows in the hierarchy.

Returns: The toplevel window containing window.

◆ get_toplevel() [2/2]

Glib::RefPtr<const Window> Gdk::Window::get_toplevel ( ) const

Gets the toplevel window that's an ancestor of window.

Any window type but Gdk::WINDOW_CHILD is considered a toplevel window, as is a Gdk::WINDOW_CHILD window that has a root window as parent.

Note that you should use get_effective_toplevel() when you want to get to a window's toplevel as seen on screen, because get_toplevel() will most likely not do what you expect if there are offscreen windows in the hierarchy.

Returns: The toplevel window containing window.

◆ get_toplevels()

static Glib::ListHandle< Glib::RefPtr<Window> > Gdk::Window::get_toplevels ( )

static

Obtains a list of all toplevel windows known to GDK on the default screen (see gdk_window_get_toplevels_for_screen()). A toplevel window is a child of the root window (see gdk_get_default_root_window()).

Returns: List of toplevel windows.

◆ get_type()

static GType Gdk::Window::get_type ( )

static

Get the GType for this class, for use with the underlying GObject type system.

◆ get_type_hint()

WindowTypeHint Gdk::Window::get_type_hint ( )

This function returns the type hint set for a window.

Returns: The type hint set for window.

◆ get_update_area()

Region Gdk::Window::get_update_area ( )

Transfers ownership of the update area from window to the caller of the function. That is, after calling this function, window will no longer have an invalid/dirty region; the update area is removed from window and handed to you. If a window has no update area, get_update_area() returns an invalid Region.

Returns: The update area for window.

◆ get_user_data()

void Gdk::Window::get_user_data ( gpointer * data )

Retrieves the user data for window, which is normally the widget that window belongs to. See set_user_data().

Parameters

data	Return location for user data.

Glib::RefPtr<Visual> Gdk::Window::get_visual ( )

Gets the Gdk::Visual describing the pixel format of window.

Returns: A Gdk::Visual.

◆ get_visual() [2/2]

Glib::RefPtr<const Visual> Gdk::Window::get_visual ( ) const

Gets the Gdk::Visual describing the pixel format of window.

Returns: A Gdk::Visual.

◆ get_width()

int Gdk::Window::get_width ( ) const

Returns the width of the given window.

On the X11 platform the returned size is the size reported in the most-recently-processed configure event, rather than the current size on the X server.

Returns: The width of window.

◆ get_window_type()

WindowType Gdk::Window::get_window_type ( ) const

Gets the type of the window. See Gdk::WindowType.

Returns: Type of window.

◆ gobj() [1/2]

GdkWindow* Gdk::Window::gobj ( )

inline

Provides access to the underlying C GObject.

Definition at line 750 of file ydkmm/ydkmm/gdkmm/window.h.

◆ gobj() [2/2]

const GdkWindow* Gdk::Window::gobj ( ) const

inline

Provides access to the underlying C GObject.

Definition at line 753 of file ydkmm/ydkmm/gdkmm/window.h.

◆ gobj_copy()

GdkWindow* Gdk::Window::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

◆ has_native()

bool Gdk::Window::has_native ( ) const

Checks whether the window has a native window or not. Note that you can use ensure_native() if a native window is needed.

Returns: true if the window has a native window, false otherwise.

◆ hide()

void Gdk::Window::hide ( )

For toplevel windows, withdraws them, so they will no longer be known to the window manager; for all windows, unmaps them, so they won't be displayed. Normally done automatically as part of gtk_widget_hide().

◆ iconify()

void Gdk::Window::iconify ( )

Asks to iconify (minimize) window. The window manager may choose to ignore the request, but normally will honor it. Using gtk_window_iconify() is preferred, if you have a Gtk::Window widget.

This function only makes sense when window is a toplevel window.

◆ input_shape_combine_mask()

void Gdk::Window::input_shape_combine_mask	(	const Glib::RefPtr< Bitmap > &	mask,
		int	x,
		int	y
	)

Like shape_combine_mask(), but the shape applies only to event handling. Mouse events which happen while the pointer position corresponds to an unset bit in the mask will be passed on the window below window.

An input shape is typically used with RGBA windows. The alpha channel of the window defines which pixels are invisible and allows for nicely antialiased borders, and the input shape controls where the window is "clickable".

On the X11 platform, this requires version 1.1 of the shape extension.

On the Win32 platform, this functionality is not present and the function does nothing.

Parameters

mask	Shape mask, or `0`.
x	X position of shape mask with respect to window.
y	Y position of shape mask with respect to window.

◆ input_shape_combine_region()

void Gdk::Window::input_shape_combine_region	(	const Region &	shape_region,
		int	offset_x,
		int	offset_y
	)

Like shape_combine_region(), but the shape applies only to event handling. Mouse events which happen while the pointer position corresponds to an unset bit in the mask will be passed on the window below window.

An input shape is typically used with RGBA windows. The alpha channel of the window defines which pixels are invisible and allows for nicely antialiased borders, and the input shape controls where the window is "clickable".

On the X11 platform, this requires version 1.1 of the shape extension.

On the Win32 platform, this functionality is not present and the function does nothing.

Parameters

shape_region	Region of window to be non-transparent.
offset_x	X position of shape_region in window coordinates.
offset_y	Y position of shape_region in window coordinates.

◆ invalidate()

void Gdk::Window::invalidate ( bool invalidate_children )

A convenience wrapper around invalidate_region() which invalidates the whole region. See invalidate_region() for details.

Parameters

invalidate_children Whether to also invalidate child windows.

◆ invalidate_rect()

void Gdk::Window::invalidate_rect	(	const Rectangle &	rect,
		bool	invalidate_children
	)

A convenience wrapper around invalidate_region() which invalidates a rectangular region. See invalidate_region() for details. See also the invalidate_rect() method overload with no rect parameter, to invalidate the whole region.

Parameters

rect	Rectangle to invalidate.
invalidate_children	Whether to also invalidate child windows.

◆ invalidate_region()

void Gdk::Window::invalidate_region	(	const Region &	region,
		bool	invalidate_children = `true`
	)

Adds region to the update area for window. The update area is the region that needs to be redrawn, or "dirty region." The call process_updates() sends one or more expose events to the window, which together cover the entire update area. An application would normally redraw the contents of window in response to those expose events.

GDK will call process_all_updates() on your behalf whenever your program returns to the main loop and becomes idle, so normally there's no need to do that manually, you just need to invalidate regions that you know should be redrawn.

The invalidate_children parameter controls whether the region of each child window that intersects region will also be invalidated. If false, then the update area for child windows will remain unaffected. See gdk_window_invalidate_maybe_recurse if you need fine grained control over which children are invalidated.

Parameters

region	A Gdk::Region.
invalidate_children	`true` to also invalidate child windows.

◆ is_input_only()

bool Gdk::Window::is_input_only ( ) const

Determines whether or not the window is an input only window.

Returns: true if window is input only.

◆ is_shaped()

bool Gdk::Window::is_shaped ( ) const

Determines whether or not the window is shaped.

Returns: true if window is shaped.

◆ is_viewable()

bool Gdk::Window::is_viewable ( ) const

Check if the window and all ancestors of the window are mapped. (This is not necessarily "viewable" in the X sense, since we only check as far as we have GDK window parents, not to the root window.)

Returns: true if the window is viewable.

◆ is_visible()

bool Gdk::Window::is_visible ( ) const

Checks whether the window has been mapped (with show() or show_unraised()).

Returns: true if the window is mapped.

◆ keyboard_grab()

GrabStatus Gdk::Window::keyboard_grab	(	bool	owner_events,
		guint32	timestamp
	)

◆ keyboard_ungrab()

static void Gdk::Window::keyboard_ungrab ( guint32 timestamp )

static

Ungrabs the keyboard on the default display, if it is grabbed by this application.

Parameters

timestamp A timestamp from a Gdk::Event, or Gdk::CURRENT_TIME if no timestamp is available.

◆ lower()

void Gdk::Window::lower ( )

Lowers window to the bottom of the Z-order (stacking order), so that other windows with the same parent window appear above window. This is true whether or not the other windows are visible.

If window is a toplevel, the window manager may choose to deny the request to move the window in the Z-order, lower() only requests the restack, does not guarantee it.

Note that show() raises the window again, so don't call this function before show(). (Try show_unraised().)

◆ maximize()

void Gdk::Window::maximize ( )

Maximizes the window. If the window was already maximized, then this function does nothing.

On X11, asks the window manager to maximize window, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don't have a concept of "maximized"; so you can't rely on the maximization actually happening. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

On Windows, reliably maximizes the window.

◆ merge_child_input_shapes()

void Gdk::Window::merge_child_input_shapes ( )

Merges the input shape masks for any child windows into the input shape mask for window. i.e. the union of all input masks for window and its children will become the new input mask for window. See input_shape_combine_mask().

This function is distinct from set_child_input_shapes() because it includes window's input shape mask in the set of shapes to be merged.

◆ merge_child_shapes()

void Gdk::Window::merge_child_shapes ( )

Merges the shape masks for any child windows into the shape mask for window. i.e. the union of all masks for window and its children will become the new mask for window. See shape_combine_mask().

This function is distinct from set_child_shapes() because it includes window's shape mask in the set of shapes to be merged.

◆ move()

void Gdk::Window::move	(	int	x,
		int	y
	)

Repositions a window relative to its parent window. For toplevel windows, window managers may ignore or modify the move; you should probably use gtk_window_move() on a Gtk::Window widget anyway, instead of using GDK functions. For child windows, the move will reliably succeed.

If you're also planning to resize the window, use move_resize() to both move and resize simultaneously, for a nicer visual effect.

Parameters

x	X coordinate relative to window's parent.
y	Y coordinate relative to window's parent.

◆ move_region()

void Gdk::Window::move_region	(	const Region &	region,
		int	dx,
		int	dy
	)

Move the part of window indicated by region by dy pixels in the Y direction and dx pixels in the X direction. The portions of region that not covered by the new position of region are invalidated.

Child windows are not moved.

Parameters

region	The Gdk::Region to move.
dx	Amount to move in the X direction.
dy	Amount to move in the Y direction.

◆ move_resize()

void Gdk::Window::move_resize	(	int	x,
		int	y,
		int	width,
		int	height
	)

Equivalent to calling move() and resize(), except that both operations are performed at once, avoiding strange visual effects. (i.e. the user may be able to see the window first move, then resize, if you don't use move_resize().)

Parameters

x	New X position relative to window's parent.
y	New Y position relative to window's parent.
width	New width.
height	New height.

◆ pointer_grab() [1/3]

GrabStatus Gdk::Window::pointer_grab	(	bool	owner_events,
		EventMask	event_mask,
		const Cursor &	cursor,
		guint32	timestamp
	)

Grabs the pointer to a specific window. Requires a corresponding call to pointer_ungrab().

Arguments:

Parameters

owner_events	Specifies whether events will be reported as is, or relative to the window.
event_mask	Masks only interesting events.
cursor	Changes the cursor for the duration of the grab.
timestamp	Specifies the time.

◆ pointer_grab() [2/3]

GrabStatus Gdk::Window::pointer_grab	(	bool	owner_events,
		EventMask	event_mask,
		const Glib::RefPtr< const Window > &	confine_to,
		const Cursor &	cursor,
		guint32	time_
	)

◆ pointer_grab() [3/3]

GrabStatus Gdk::Window::pointer_grab	(	bool	owner_events,
		EventMask	event_mask,
		guint32	timestamp
	)

Grabs the pointer to a specific window. Requires a corresponding call to pointer_ungrab().

Arguments:

Parameters

owner_events	Specifies whether events will be reported as is, or relative to the window.
event_mask	Masks only interesting events.
timestamp	Specifies the time.

◆ pointer_ungrab()

static void Gdk::Window::pointer_ungrab ( guint32 timestamp )

static

Ungrabs the pointer on the default display, if it is grabbed by this application.

Parameters

timestamp A timestamp from a Gdk::Event, or Gdk::CURRENT_TIME if no timestamp is available.

◆ process_all_updates()

static void Gdk::Window::process_all_updates ( )

static

Calls process_updates() for all windows (see Gdk::Window) in the application.

◆ process_updates()

void Gdk::Window::process_updates ( bool update_children )

Sends one or more expose events to window. The areas in each expose event will cover the entire update area for the window (see invalidate_region() for details). Normally GDK calls process_all_updates() on your behalf, so there's no need to call this function unless you want to force expose events to be delivered immediately and synchronously (vs. the usual case, where GDK delivers them in an idle handler). Occasionally this is useful to produce nicer scrolling behavior, for example.

Parameters

update_children Whether to also process updates for child windows.

◆ raise()

void Gdk::Window::raise ( )

Raises window to the top of the Z-order (stacking order), so that other windows with the same parent window appear below window. This is true whether or not the windows are visible.

If window is a toplevel, the window manager may choose to deny the request to move the window in the Z-order, raise() only requests the restack, does not guarantee it.

◆ redirect_to_drawable()

void Gdk::Window::redirect_to_drawable	(	const Glib::RefPtr< Drawable > &	drawable,
		int	src_x,
		int	src_y,
		int	dest_x,
		int	dest_y,
		int	width,
		int	height
	)

Redirects drawing into window so that drawing to the window in the rectangle specified by src_x, src_y, width and height is also drawn into drawable at dest_x, dest_y.

Only drawing between begin_paint_region() or begin_paint_rect() and end_paint() is redirected.

Redirection is active until remove_redirection() is called.

Parameters

drawable	A Gdk::Drawable.
src_x	X position in window.
src_y	Y position in window.
dest_x	X position in drawable.
dest_y	Y position in drawable.
width	Width of redirection, or -1 to use the width of window.
height	Height of redirection or -1 to use the height of window.

void Gdk::Window::register_dnd ( )

◆ remove_filter()

void Gdk::Window::remove_filter	(	GdkFilterFunc	function,
		gpointer	data
	)

Remove a filter previously added with add_filter().

Parameters

function	Previously-added filter function.
data	User data for previously-added filter function.

◆ remove_redirection()

void Gdk::Window::remove_redirection ( )

Removes any active redirection started by redirect_to_drawable().

◆ reparent()

void Gdk::Window::reparent	(	const Glib::RefPtr< Window > &	new_parent,
		int	x,
		int	y
	)

Reparents window into the given new_parent. The window being reparented will be unmapped as a side effect.

Parameters

new_parent	New parent to move window into.
x	X location inside the new parent.
y	Y location inside the new parent.

◆ resize()

void Gdk::Window::resize	(	int	width,
		int	height
	)

Resizes window; for toplevel windows, asks the window manager to resize the window. The window manager may not allow the resize. When using GTK+, use gtk_window_resize() instead of this low-level GDK function.

Windows may not be resized below 1x1.

If you're also planning to move the window, use move_resize() to both move and resize simultaneously, for a nicer visual effect.

Parameters

width	New width of the window.
height	New height of the window.

◆ restack() [1/2]

void Gdk::Window::restack ( bool above )

Changes the position of this window in the Z-order (stacking order). This either raises (if above is true) or lowers the window.

If this is a toplevel, the window manager may choose to deny the request to move the window in the Z-order. restack() only requests the restack but does not guarantee it.

Parameters

above Whether to raise or lower the window.

◆ restack() [2/2]

void Gdk::Window::restack	(	const Glib::RefPtr< Window > &	sibling,
		bool	above
	)

Changes the position of window in the Z-order (stacking order), so that it is above sibling (if above is true) or below sibling (if above is false).

If sibling is 0, then this either raises (if above is true) or lowers the window.

If window is a toplevel, the window manager may choose to deny the request to move the window in the Z-order, restack() only requests the restack, does not guarantee it.

Parameters

sibling	A Gdk::Window that is a sibling of window, or `0`.
above	A boolean.

◆ scroll()

void Gdk::Window::scroll	(	int	dx,
		int	dy
	)

Scroll the contents of its window, both pixels and children, by the given amount. Portions of the window that the scroll operation brings in from offscreen areas are invalidated.

Parameters

dx	Amount to scroll in the X direction.
dy	Amount to scroll in the Y direction.

◆ set_accept_focus()

void Gdk::Window::set_accept_focus ( bool accept_focus = true )

Setting accept_focus to false hints the desktop environment that the window doesn't want to receive input focus.

On X, it is the responsibility of the window manager to interpret this hint. ICCCM-compliant window manager usually respect it.

Parameters

accept_focus true if the window should receive input focus.

◆ set_back_pixmap()

void Gdk::Window::set_back_pixmap	(	const Glib::RefPtr< Pixmap > &	pixmap,
		bool	parent_relative = `true`
	)

Sets the background pixmap of window. A background pixmap will be tiled, positioning the first tile at the origin of window, or if parent_relative is true, the tiling will be done based on the origin of the parent window (useful to align tiles in a parent with tiles in a child).

The windowing system will normally fill a window with its background when the window is obscured then exposed, and when you call clear().

◆ set_background()

void Gdk::Window::set_background ( const Color & color )

Sets the background color of window. (However, when using GTK+, set the background of a widget with gtk_widget_modify_bg() - if you're an application - or gtk_style_set_background() - if you're implementing a custom widget.)

The color must be allocated; gdk_rgb_find_color() is the best way to allocate a color.

See also gdk_window_set_background_pixmap().

Parameters

color An allocated Gdk::Color.

◆ set_child_input_shapes()

void Gdk::Window::set_child_input_shapes ( )

Sets the input shape mask of window to the union of input shape masks for all children of window, ignoring the input shape mask of window itself. Contrast with merge_child_input_shapes() which includes the input shape mask of window in the masks to be merged.

◆ set_child_shapes()

void Gdk::Window::set_child_shapes ( )

Sets the shape mask of window to the union of shape masks for all children of window, ignoring the shape mask of window itself. Contrast with merge_child_shapes() which includes the shape mask of window in the masks to be merged.

◆ set_composited()

void Gdk::Window::set_composited ( bool composited = TRUE )

Sets a Gdk::Window as composited, or unsets it. Composited windows do not automatically have their contents drawn to the screen. Drawing is redirected to an offscreen buffer and an expose event is emitted on the parent of the composited window. It is the responsibility of the parent's expose handler to manually merge the off-screen content onto the screen in whatever way it sees fit.

It only makes sense for child windows to be composited; see set_opacity() if you need translucent toplevel windows.

An additional effect of this call is that the area of this window is no longer clipped from regions marked for invalidation on its parent. Draws done on the parent window are also no longer clipped by the child.

This call is only supported on some systems (currently, only X11 with new enough Xcomposite and Xdamage extensions). You must call Gdk::Display::supports_composite() to check if setting a window as composited is supported before attempting to do so.

Parameters

composited true to set the window as composited.

◆ set_cursor() [1/2]

void Gdk::Window::set_cursor ( )

Use the parent window's cursor. For top-level windows this means that it will use the default cursor for the ROOT window.

◆ set_cursor() [2/2]

void Gdk::Window::set_cursor ( const Cursor & cursor )

Sets the mouse pointer for a Gdk::Window. To make the cursor invisible, use Gdk::Cursor::new_from_pixmap() to create a cursor with no pixels in it.

Parameters

cursor A cursor.

◆ set_debug_updates()

static void Gdk::Window::set_debug_updates ( bool setting = true )

static

With update debugging enabled, calls to invalidate_region() clear the invalidated region of the screen to a noticeable color, and GDK pauses for a short time before sending exposes to windows during process_updates(). The net effect is that you can see the invalid region for each window and watch redraws as they occur. This allows you to diagnose inefficiencies in your application.

In essence, because the GDK rendering model prevents all flicker, if you are redrawing the same region 400 times you may never notice, aside from noticing a speed problem. Enabling update debugging causes GTK to flicker slowly and noticeably, so you can see exactly what's being redrawn when, in what order.

The –gtk-debug=updates command line option passed to GTK+ programs enables this debug option at application startup time. That's usually more useful than calling set_debug_updates() yourself, though you might want to use this function to enable updates sometime after application startup time.

Parameters

setting true to turn on update debugging.

◆ set_decorations()

void Gdk::Window::set_decorations ( WMDecoration decorations )

"Decorations" are the features the window manager adds to a toplevel Gdk::Window. This function sets the traditional Motif window manager hints that tell the window manager which decorations you would like your window to have. Usually you should use gtk_window_set_decorated() on a Gtk::Window instead of using the GDK function directly.

The decorations argument is the logical OR of the fields in the Gdk::WMDecoration enumeration. If Gdk::DECOR_ALL is included in the mask, the other bits indicate which decorations should be turned off. If Gdk::DECOR_ALL is not included, then the other bits indicate which decorations should be turned on.

Most window managers honor a decorations hint of 0 to disable all decorations, but very few honor all possible combinations of bits.

Parameters

decorations Decoration hint mask.

◆ set_events()

void Gdk::Window::set_events ( EventMask event_mask )

The event mask for a window determines which events will be reported for that window. For example, an event mask including Gdk::BUTTON_PRESS_MASK means the window should report button press events. The event mask is the bitwise OR of values from the Gdk::EventMask enumeration.

Parameters

event_mask Event mask for window.

◆ set_focus_on_map()

void Gdk::Window::set_focus_on_map ( bool focus_on_map )

Setting focus_on_map to false hints the desktop environment that the window doesn't want to receive input focus when it is mapped.
focus_on_map should be turned off for windows that aren't triggered interactively (such as popups from network activity).

On X, it is the responsibility of the window manager to interpret this hint. Window managers following the freedesktop.org window manager extension specification should respect it.

Parameters

focus_on_map true if the window should receive input focus when mapped.

◆ set_functions()

void Gdk::Window::set_functions ( WMFunction functions )

Sets hints about the window management functions to make available via buttons on the window frame.

On the X backend, this function sets the traditional Motif window manager hint for this purpose. However, few window managers do anything reliable or interesting with this hint. Many ignore it entirely.

The functions argument is the logical OR of values from the Gdk::WMFunction enumeration. If the bitmask includes Gdk::FUNC_ALL, then the other bits indicate which functions to disable; if it doesn't include Gdk::FUNC_ALL, it indicates which functions to enable.

Parameters

functions Bitmask of operations to allow on window.

◆ set_geometry_hints()

void Gdk::Window::set_geometry_hints	(	const Geometry &	geometry,
		WindowHints	geom_mask
	)

Sets the geometry hints for window. Hints flagged in geom_mask are set, hints not flagged in geom_mask are unset. To unset all hints, use a geom_mask of 0 and a geometry of 0.

This function provides hints to the windowing system about acceptable sizes for a toplevel window. The purpose of this is to constrain user resizing, but the windowing system will typically (but is not required to) also constrain the current size of the window to the provided values and constrain programatic resizing via resize() or move_resize().

Note that on X11, this effect has no effect on windows of type Gdk::WINDOW_TEMP or windows where override redirect has been turned on via set_override_redirect() since these windows are not resizable by the user.

Since you can't count on the windowing system doing the constraints for programmatic resizes, you should generally call constrain_size() yourself to determine appropriate sizes.

Parameters

geometry	Geometry hints.
geom_mask	Bitmask indicating fields of geometry to pay attention to.

◆ set_group()

void Gdk::Window::set_group ( const Glib::RefPtr< Window > & leader )

Sets the group leader window for window. By default, GDK sets the group leader for all toplevel windows to a global window implicitly created by GDK. With this function you can override this default.

The group leader window allows the window manager to distinguish all windows that belong to a single application. It may for example allow users to minimize/unminimize all windows belonging to an application at once. You should only set a non-default group window if your application pretends to be multiple applications.

Parameters

leader Group leader window, or 0 to restore the default group leader window.

◆ set_icon() [1/2]

void Gdk::Window::set_icon	(	const Glib::RefPtr< Window > &	icon_window,
		const Glib::RefPtr< Pixmap > &	pixmap
	)

◆ set_icon() [2/2]

void Gdk::Window::set_icon	(	const Glib::RefPtr< Window > &	icon_window,
		const Glib::RefPtr< Pixmap > &	pixmap,
		const Glib::RefPtr< Bitmap > &	mask
	)

Sets the icon of window as a pixmap or window. If using GTK+, investigate gtk_window_set_default_icon_list() first, and then gtk_window_set_icon_list() and gtk_window_set_icon(). If those don't meet your needs, look at set_icon_list(). Only if all those are too high-level do you want to fall back to set_icon().

Parameters

icon_window	A Gdk::Window to use for the icon.
pixmap	A Gdk::Pixmap to use as the icon,.
mask	A 1-bit pixmap (Gdk::Bitmap) to use as mask for pixmap.

◆ set_icon_list()

void Gdk::Window::set_icon_list ( const Glib::ListHandle< Glib::RefPtr< Gdk::Pixbuf > > & pixbufs )

Sets a list of icons for the window. One of these will be used to represent the window when it has been iconified. The icon is usually shown in an icon box or some sort of task bar. Which icon size is shown depends on the window manager. The window manager can scale the icon but setting several size icons can give better image quality since the window manager may only need to scale the icon by a small amount or not at all.

Parameters

pixbufs A list of pixbufs, of different sizes.

◆ set_icon_name()

void Gdk::Window::set_icon_name ( const Glib::ustring & name )

Windows may have a name used while minimized, distinct from the name they display in their titlebar. Most of the time this is a bad idea from a user interface standpoint. But you can set such a name with this function, if you like.

After calling this with a non-0 name, calls to set_title() will not update the icon title.

Using 0 for name unsets the icon title; further calls to set_title() will again update the icon title as well.

Parameters

name	Name of window while iconified (minimized).

◆ set_keep_above()

void Gdk::Window::set_keep_above ( bool setting = true )

Set if window must be kept above other windows. If the window was already above, then this function does nothing.

On X11, asks the window manager to keep window above, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don't have a concept of "keep above"; so you can't rely on the window being kept above. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

Parameters

setting Whether to keep window above other windows.

◆ set_keep_below()

void Gdk::Window::set_keep_below ( bool setting = true )

Set if window must be kept below other windows. If the window was already below, then this function does nothing.

On X11, asks the window manager to keep window below, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don't have a concept of "keep below"; so you can't rely on the window being kept below. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

Parameters

setting Whether to keep window below other windows.

◆ set_modal_hint()

void Gdk::Window::set_modal_hint ( bool modal = true )

The application can use this hint to tell the window manager that a certain window has modal behaviour. The window manager can use this information to handle modal windows in a special way.

You should only use this on windows for which you have previously called set_transient_for()

Parameters

modal true if the window is modal, false otherwise.

◆ set_offscreen_embedder()

void Gdk::Window::set_offscreen_embedder ( const Glib::RefPtr< Window > & embedder )

Sets window to be embedded in embedder.

To fully embed an offscreen window, in addition to calling this function, it is also necessary to handle the Gdk::Window::signal_pick_embedded_child() signal on the embedder and the Gdk::Window::signal_to_embedder() and Gdk::Window::signal_from_embedder() signals on window.

Parameters

embedder The Gdk::Window that window gets embedded in.

◆ set_opacity()

void Gdk::Window::set_opacity ( double opacity )

Request the windowing system to make window partially transparent, with opacity 0 being fully transparent and 1 fully opaque. (Values of the opacity parameter are clamped to the [0,1] range.)

On X11, this works only on X screens with a compositing manager running.

For setting up per-pixel alpha, see Gdk::Screen::get_rgba_colormap(). For making non-toplevel windows translucent, see set_composited().

Parameters

opacity Opacity.

◆ set_override_redirect()

void Gdk::Window::set_override_redirect ( bool override_redirect = true )

An override redirect window is not under the control of the window manager. This means it won't have a titlebar, won't be minimizable, etc. - it will be entirely under the control of the application. The window manager can't see the override redirect window at all.

Override redirect should only be used for short-lived temporary windows, such as popup menus. Gtk::Menu uses an override redirect window in its implementation, for example.

Parameters

override_redirect true if window should be override redirect.

◆ set_role()

void Gdk::Window::set_role ( const Glib::ustring & role )

When using GTK+, typically you should use gtk_window_set_role() instead of this low-level function.

The window manager and session manager use a window's role to distinguish it from other kinds of window in the same application. When an application is restarted after being saved in a previous session, all windows with the same title and role are treated as interchangeable. So if you have two windows with the same title that should be distinguished for session management purposes, you should set the role on those windows. It doesn't matter what string you use for the role, as long as you have a different role for each non-interchangeable kind of window.

Parameters

role	A string indicating its role.

◆ set_skip_pager_hint()

void Gdk::Window::set_skip_pager_hint ( bool skips_pager = true )

Toggles whether a window should appear in a pager (workspace switcher, or other desktop utility program that displays a small thumbnail representation of the windows on the desktop). If a window's semantic type as specified with set_type_hint() already fully describes the window, this function should not be called in addition, instead you should allow the window to be treated according to standard policy for its semantic type.

Parameters

skips_pager true to skip the pager.

◆ set_skip_taskbar_hint()

void Gdk::Window::set_skip_taskbar_hint ( bool skips_taskbar = true )

Toggles whether a window should appear in a task list or window list. If a window's semantic type as specified with set_type_hint() already fully describes the window, this function should not be called in addition, instead you should allow the window to be treated according to standard policy for its semantic type.

Parameters

skips_taskbar true to skip the taskbar.

◆ set_sm_client_id()

static void Gdk::Window::set_sm_client_id ( const Glib::ustring & sm_client_id )

static

Sets the <literal>SM_CLIENT_ID</literal> property on the application's leader window so that the window manager can save the application's state using the X11R6 ICCCM session management protocol.

See the X Session Management Library documentation for more information on session management and the Inter-Client Communication Conventions Manual (ICCCM) for information on the <literal>WM_CLIENT_LEADER</literal> property. (Both documents are part of the X Window System distribution.)

Parameters

sm_client_id The client id assigned by the session manager when the connection was opened.

◆ set_startup_id()

void Gdk::Window::set_startup_id ( const Glib::ustring & startup_id )

When using GTK+, typically you should use gtk_window_set_startup_id() instead of this low-level function.

Parameters

startup_id A string with startup-notification identifier.

◆ set_static_gravities()

bool Gdk::Window::set_static_gravities ( bool use_static = true )

Set the bit gravity of the given window to static, and flag it so all children get static subwindow gravity. This is used if you are implementing scary features that involve deep knowledge of the windowing system. Don't worry about it unless you have to.

Parameters

use_static true to turn on static gravity.

Returns: true if the server supports static gravity.

◆ set_title()

void Gdk::Window::set_title ( const Glib::ustring & title )

Sets the title of a toplevel window, to be displayed in the titlebar. If you haven't explicitly set the icon name for the window (using set_icon_name()), the icon name will be set to title as well. title must be in UTF-8 encoding (as with all user-readable strings in GDK/GTK+). title may not be 0.

Parameters

title Title of window.

◆ set_transient_for()

void Gdk::Window::set_transient_for ( const Glib::RefPtr< Window > & parent )

Indicates to the window manager that window is a transient dialog associated with the application window parent. This allows the window manager to do things like center window on parent and keep window above parent.

See gtk_window_set_transient_for() if you're using Gtk::Window or Gtk::Dialog.

Parameters

parent Another toplevel Gdk::Window.

◆ set_type_hint()

void Gdk::Window::set_type_hint ( WindowTypeHint hint )

The application can use this call to provide a hint to the window manager about the functionality of a window. The window manager can use this information when determining the decoration and behaviour of the window.

The hint must be set before the window is mapped.

Parameters

hint	A hint of the function this window will have.

◆ set_urgency_hint()

void Gdk::Window::set_urgency_hint ( bool urgent = true )

Toggles whether a window needs the user's urgent attention.

Parameters

urgent true if the window is urgent.

◆ set_user_data()

void Gdk::Window::set_user_data ( gpointer user_data )

For most purposes this function is deprecated in favor of Glib::object_set_data(). However, for historical reasons GTK+ stores the Gtk::Widget that owns a Gdk::Window as user data on the Gdk::Window. So, custom widget implementations should use this function for that. If GTK+ receives an event for a Gdk::Window, and the user data for the window is non-0, GTK+ will assume the user data is a Gtk::Widget, and forward the event to that widget.

Parameters

user_data User data.

◆ shape_combine_mask()

void Gdk::Window::shape_combine_mask	(	const Glib::RefPtr< Bitmap > &	mask,
		int	x,
		int	y
	)

Applies a shape mask to window. Pixels in window corresponding to set bits in the mask will be visible; pixels in window corresponding to unset bits in the mask will be transparent. This gives a non-rectangular window.

If mask is 0, the shape mask will be unset, and the x/ y parameters are not used.

On the X11 platform, this uses an X server extension which is widely available on most common platforms, but not available on very old X servers, and occasionally the implementation will be buggy. On servers without the shape extension, this function will do nothing.

This function works on both toplevel and child windows.

Parameters

mask	Shape mask.
x	X position of shape mask with respect to window.
y	Y position of shape mask with respect to window.

◆ shape_combine_region()

void Gdk::Window::shape_combine_region	(	const Region &	shape_region,
		int	offset_x,
		int	offset_y
	)

Makes pixels in window outside shape_region be transparent, so that the window may be nonrectangular. See also shape_combine_mask() to use a bitmap as the mask.

If shape_region is 0, the shape will be unset, so the whole window will be opaque again. offset_x and offset_y are ignored if shape_region is 0.

On the X11 platform, this uses an X server extension which is widely available on most common platforms, but not available on very old X servers, and occasionally the implementation will be buggy. On servers without the shape extension, this function will do nothing.

This function works on both toplevel and child windows.

Parameters

shape_region	Region of window to be non-transparent.
offset_x	X position of shape_region in window coordinates.
offset_y	Y position of shape_region in window coordinates.

◆ show()

void Gdk::Window::show ( )

Like show_unraised(), but also raises the window to the top of the window stack (moves the window to the front of the Z-order).

This function maps a window so it's visible onscreen. Its opposite is hide().

When implementing a Gtk::Widget, you should call this function on the widget's Gdk::Window as part of the "map" method.

◆ show_unraised()

void Gdk::Window::show_unraised ( )

Shows a Gdk::Window onscreen, but does not modify its stacking order. In contrast, show() will raise the window to the top of the window stack.

On the X11 platform, in Xlib terms, this function calls XMapWindow() (it also updates some internal GDK state, which means that you can't really use XMapWindow() directly on a GDK window).

◆ stick()

void Gdk::Window::stick ( )

"Pins" a window such that it's on all workspaces and does not scroll with viewports, for window managers that have scrollable viewports. (When using Gtk::Window, gtk_window_stick() may be more useful.)

On the X11 platform, this function depends on window manager support, so may have no effect with many window managers. However, GDK will do the best it can to convince the window manager to stick the window. For window managers that don't support this operation, there's nothing you can do to force it to happen.

◆ thaw_updates()

void Gdk::Window::thaw_updates ( )

Thaws a window frozen with Gdk::Window::freeze_updates().

◆ unfullscreen()

void Gdk::Window::unfullscreen ( )

Moves the window out of fullscreen mode. If the window was not fullscreen, does nothing.

On X11, asks the window manager to move window out of the fullscreen state, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don't have a concept of "fullscreen"; so you can't rely on the unfullscreenification actually happening. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

◆ unmaximize()

void Gdk::Window::unmaximize ( )

Unmaximizes the window. If the window wasn't maximized, then this function does nothing.

On X11, asks the window manager to unmaximize window, if the window manager supports this operation. Not all window managers support this, and some deliberately ignore it or don't have a concept of "maximized"; so you can't rely on the unmaximization actually happening. But it will happen with most standard window managers, and GDK makes a best effort to get it to happen.

On Windows, reliably unmaximizes the window.

◆ unset_back_pixmap()

void Gdk::Window::unset_back_pixmap ( )

Unsets the background pixmap of window so that the window will have no background. A window with no background will never have its background filled by the windowing system, instead the window will contain whatever pixels were already in the corresponding area of the display.

See also: set_back_pixmap().

◆ unset_icon()

void Gdk::Window::unset_icon ( )

◆ unset_shape_combine_mask()

void Gdk::Window::unset_shape_combine_mask ( )

◆ unset_sm_client_id()

static void Gdk::Window::unset_sm_client_id ( )

static

◆ unstick()

void Gdk::Window::unstick ( )

Reverse operation for stick(); see stick(), and gtk_window_unstick().

◆ withdraw()

void Gdk::Window::withdraw ( )

Withdraws a window (unmaps it and asks the window manager to forget about it). This function is not really useful as hide() automatically withdraws toplevel windows before hiding them.
