drag_data_delete

Description:

public abstract bool drag_data_delete (TreePath path)

Asks the 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:

this

a TreeDragSource
path

row that was being dragged

Returns:

true if the row was successfully deleted
