Detailed Description

Interface for Drag-and-Drop sources in Gtk::TreeView.

Deprecated:: 4.10: List views use widgets to display their contents. You can use Gtk::DragSource to implement a drag source.

◆ add_interface()

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

static

◆ 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!

Deprecated: 4.10: Use list models instead

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()

Glib::RefPtr< Gdk::ContentProvider > Gtk::TreeDragSource::drag_data_get ( const TreeModel::Path & path ) const

Asks the Gtk::TreeDragSource to return a Gdk::ContentProvider representing the row at path.

Should robustly handle a path no longer found in the model!

Deprecated: 4.10: Use list models instead

Parameters

path	Row that was dragged.

Returns: A Gdk::ContentProvider for the given path.

◆ drag_data_get_vfunc()

virtual Glib::RefPtr< Gdk::ContentProvider > Gtk::TreeDragSource::drag_data_get_vfunc ( const TreeModel::Path & path ) 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.

◆ gobj() [2/2]

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

inline

Provides access to the underlying C GObject.

◆ operator=()

TreeDragSource & Gtk::TreeDragSource::operator= ( TreeDragSource && src )

noexcept

◆ 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.

Deprecated: 4.10: Use list models instead

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

Friends And Related Symbol Documentation

◆ wrap()

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

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.
