Interface

GtkTreeDragSource

Description [src]

interface Gtk.TreeDragSource : GObject.Object

Interface for Drag-and-Drop destinations in GtkTreeView.

Prerequisite

In order to implement TreeDragSource, your type must inherit from GObject.

Instance methods

gtk_tree_drag_source_drag_data_delete

Asks the GtkTreeDragSource 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!

gtk_tree_drag_source_drag_data_get

Asks the GtkTreeDragSource to return a GdkContentProvider representing the row at path. Should robustly handle a path no longer found in the model!

gtk_tree_drag_source_row_draggable

Asks the GtkTreeDragSource 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.
