Detailed Description

Base class for text-editing widgets.

The Gtk::Editable class is a base class for widgets for editing text, such as Gtk::Entry. It cannot be instantiated by itself. The editable class contains functions for generically manipulating an editable widget, a large number of action signals used for key bindings, and several signals that an application can connect to to modify the behavior of a widget.

◆ Editable()

Gtk::Editable::Editable ( )

protected

You should derive from this class to use it.

Member Function Documentation

◆ add_interface()

static void Gtk::Editable::add_interface ( GType gtype_implementer )

static

◆ copy_clipboard()

void Gtk::Editable::copy_clipboard ( )

Copies the contents of the currently selected content in the editable and puts it on the clipboard.

◆ cut_clipboard()

void Gtk::Editable::cut_clipboard ( )

Removes the contents of the currently selected content in the editable and puts it on the clipboard.

◆ delete_selection()

void Gtk::Editable::delete_selection ( )

Deletes the currently selected text of the editable. This call doesn't do anything if there is no selected text.

◆ delete_text()

void Gtk::Editable::delete_text	(	int	start_pos,
		int	end_pos
	)

Deletes a sequence of characters. The characters that are deleted are those characters at positions from start_pos up to, but not including end_pos. If end_pos is negative, then the the characters deleted are those from start_pos to the end of the text.

Note that the positions are specified in characters, not bytes.

Parameters

start_pos	Start position.
end_pos	End position.

◆ delete_text_vfunc()

virtual void Gtk::Editable::delete_text_vfunc	(	int	start_pos,
		int	end_pos
	)

protectedvirtual

◆ get_chars()

Glib::ustring Gtk::Editable::get_chars	(	int	start_pos,
		int	end_pos
	)		const

Retrieves a sequence of characters. The characters that are retrieved are those characters at positions from start_pos up to, but not including end_pos. If end_pos is negative, then the the characters retrieved are those characters from start_pos to the end of the text.

Note that positions are specified in characters, not bytes.

Parameters

start_pos	Start of text.
end_pos	End of text.

Returns: A pointer to the contents of the widget as a string. This string is allocated by the Gtk::Editable implementation and should be freed by the caller.

◆ get_chars_vfunc()

virtual Glib::ustring Gtk::Editable::get_chars_vfunc	(	int	start_pos,
		int	end_pos
	)		const

protectedvirtual

◆ get_editable()

bool Gtk::Editable::get_editable ( ) const

Retrieves whether editable is editable. See set_editable().

Returns: true if editable is editable.

◆ get_position()

int Gtk::Editable::get_position ( ) const

Retrieves the current position of the cursor relative to the start of the content of the editable.

Note that this position is in characters, not in bytes.

Returns: The cursor position.

◆ get_position_vfunc()

virtual int Gtk::Editable::get_position_vfunc ( ) const

protectedvirtual

◆ get_selection_bounds()

bool Gtk::Editable::get_selection_bounds	(	int &	start_pos,
		int &	end_pos
	)		const

Retrieves the selection bound of the editable. start_pos will be filled with the start of the selection and end_pos with end. If no text was selected both will be identical and false will be returned.

Note that positions are specified in characters, not bytes.

Parameters

start_pos	Location to store the starting position, or `0`.
end_pos	Location to store the end position, or `0`.

Returns: true if an area is selected, false otherwise.

◆ get_selection_bounds_vfunc()

virtual bool Gtk::Editable::get_selection_bounds_vfunc	(	int &	start_pos,
		int &	end_pos
	)		const

protectedvirtual

◆ get_type()

static GType Gtk::Editable::get_type ( )

static

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

◆ gobj() [1/2]

GtkEditable* Gtk::Editable::gobj ( )

inline

Provides access to the underlying C GObject.

Definition at line 123 of file editable.h.

◆ gobj() [2/2]

const GtkEditable* Gtk::Editable::gobj ( ) const

inline

Provides access to the underlying C GObject.

Definition at line 126 of file editable.h.

◆ insert_text()

void Gtk::Editable::insert_text	(	const Glib::ustring &	text,
		int	length,
		int &	position
	)

Inserts new_text_length bytes of new_text into the contents of the widget, at position position.

Note that the position is in characters, not in bytes. The function updates position to point after the newly inserted text.

Parameters

text	The text to append.
length	The length of the text in bytes, or -1.
position	Location of the position text will be inserted at.

◆ on_changed()

virtual void Gtk::Editable::on_changed ( )

protectedvirtual

This is a default handler for the signal signal_changed().

◆ on_delete_text()

virtual void Gtk::Editable::on_delete_text	(	int	start_pos,
		int	end_pos
	)

protectedvirtual

This is a default handler for the signal signal_delete_text().

◆ on_insert_text()

virtual void Gtk::Editable::on_insert_text	(	const Glib::ustring &	text,
		int *	position
	)

protectedvirtual

This is a default handler for the signal signal_insert_text().

◆ paste_clipboard()

void Gtk::Editable::paste_clipboard ( )

Pastes the content of the clipboard to the current position of the cursor in the editable.

◆ select_region()

void Gtk::Editable::select_region	(	int	start_pos,
		int	end_pos
	)

Selects a region of text. The characters that are selected are those characters at positions from start_pos up to, but not including end_pos. If end_pos is negative, then the the characters selected are those characters from start_pos to the end of the text.

Note that positions are specified in characters, not bytes.

Parameters

start_pos	Start of region.
end_pos	End of region.

◆ select_region_vfunc()

virtual void Gtk::Editable::select_region_vfunc	(	int	start_pos,
		int	end_pos
	)

protectedvirtual

◆ set_editable()

void Gtk::Editable::set_editable ( bool is_editable = true )

Determines if the user can edit the text in the editable widget or not.

Parameters

is_editable true if the user is allowed to edit the text in the widget.

◆ set_position()

void Gtk::Editable::set_position ( int position )

Sets the cursor position in the editable to the given value.

The cursor is displayed before the character with the given (base 0) index in the contents of the editable. The value must be less than or equal to the number of characters in the editable. A value of -1 indicates that the position should be set after the last character of the editable. Note that position is in characters, not in bytes.

Parameters

position The position of the cursor.
