Yo lo hago de esta forma:
I do it this way:
my_widget = gtk. . . .
my_widget.drag_source_set(gtk.gdk.BUTTON1_MASK, targets,
gtk.gdk.ACTION_MOVE)
. . .
my_vbox.drag_dest_set(gtk.DEST_DEFAULT_ALL, targets,
gtk.gdk.ACTION_MOVE)
my_vbox.connect("drag-drop", self.drag_drop)
. . .
def drag_drop(self, destino, drag_context, x, y, cosas):
objeto = drag_context.get_source_widget()
if objeto.get_parent() == destino: return
objeto.get_parent().remove(objeto)
destino.pack_start(objeto, False, False, 1)
targets = [("Moviendo", gtk.TARGET_SAME_APP, 1)]
