-The basic principles behind setting up drag-and-drop source and destination objects are simple, however, some widgets support dnd by design, while most of the Gtk widgets do not. Naturally, sometimes you need to mix the two kinds of (the dnd and the non-dnd) widgets. This complicates both the teaching and the learning of the Gtk's dnd metaphor a bit. This perhaps is one of the you reason in most of the currently available Gtk drag-and-drop tutorials you find rather incomplete or useless examples, such as dragging a button to a label, which in itself is a nonsense proposition, since a label can never contain a button on the first place. Nevertheless, as we will see shortly using a button and a label for a source and destination after all makes sense, when the students understand that in this case the source and destination objects themselves are being also dragged and/or manipulated by the dnd.
