Asks the gtk.tree_drag_source.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!
Asks the gtk.tree_drag_source.TreeDragSource to return a gdk.content_provider.ContentProvider representing the row at path. Should robustly handle a path no longer found in the model!
Asks the gtk.tree_drag_source.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: List views use widgets to display their contents. You can use gtk.drag_source.DragSource to implement a drag source
Interface for Drag-and-Drop destinations in gtk.tree_view.TreeView.
