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.

You should derive from this class to use it.

◆ drag_data_delete()
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.

◆ get_type()

Get the GType for this class, for use with the underlying GObject type system.
◆ gobj() [1/2]
Provides access to the underlying C GObject.
◆ gobj() [2/2]
Provides access to the underlying C GObject.
◆ operator=()
◆ row_draggable()
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()
◆ wrap()
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.
