Methods

vfunc_drag_data_delete vfunc_drag_data_get vfunc_row_draggable

Methods

  • 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

    Returns boolean

  • 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: Gtk.TreePath

      row on which user is initiating a drag

    Returns boolean
