Constructor & Destructor Documentation

TreeDragSource()

Gtk::TreeDragSource::TreeDragSource ( )

You should derive from this class to use it.

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

drag_data_delete()

bool Gtk::TreeDragSource::drag_data_delete

(

const TreeModel::Path &

path

)

Asks the Gtk::TreeDragSource to delete the row at path, because it was moved somewhere else via drag-and-drop. Returns false if the deletion fails because path no longer exists, or for some model-specific reason. Should robustly handle a path no longer found in the model!

Parameters

path	Row that was being dragged.

Returns

true if the row was successfully deleted.

drag_data_delete_vfunc()

virtual bool Gtk::TreeDragSource::drag_data_delete_vfunc ( const TreeModel::Path &  path )

protectedvirtual

drag_data_get()

bool Gtk::TreeDragSource::drag_data_get	(	const TreeModel::Path &	path,
		SelectionData &	selection_data
	)

Asks the Gtk::TreeDragSource to fill in selection_data with a representation of the row at path. selection_data->target gives the required type of the data. Should robustly handle a path no longer found in the model!

Parameters

path	Row that was dragged.
selection_data	A Gtk::SelectionData to fill with data from the dragged row.

Returns

true if data of the required type was provided.

drag_data_get_vfunc()

virtual bool Gtk::TreeDragSource::drag_data_get_vfunc ( const TreeModel::Path &  path, SelectionData &  selection_data  ) const

protectedvirtual

get_type()

static GType Gtk::TreeDragSource::get_type ( )

static

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

gobj() [1/2]

GtkTreeDragSource* Gtk::TreeDragSource::gobj ( )

inline

Provides access to the underlying C GObject.

Definition at line 119 of file treedragsource.h.

gobj() [2/2]

const GtkTreeDragSource* Gtk::TreeDragSource::gobj ( ) const

inline

Provides access to the underlying C GObject.

Definition at line 122 of file treedragsource.h.

row_draggable()

bool Gtk::TreeDragSource::row_draggable

(

const TreeModel::Path &

path

)

const

Asks the Gtk::TreeDragSource whether a particular row can be used as the source of a DND operation. If the source doesn't implement this interface, the row is assumed draggable.

Parameters

path	Row on which user is initiating a drag.

Returns

true if the row can be dragged.

row_draggable_vfunc()

virtual bool Gtk::TreeDragSource::row_draggable_vfunc ( const TreeModel::Path &  path ) const

protectedvirtual

Reimplemented in PluginTreeStore.

Friends And Related Function Documentation

wrap()

Glib::RefPtr< Gtk::TreeDragSource > wrap ( GtkTreeDragSource *  object, bool  take_copy = false  )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
