gtk.TreeDragSource an interface that manages the source data transfer for a gtk.TreeView drag and drop operation gtk.TreeDragSource gobject.GInterface row_draggable path drag_data_delete path drag_data_get path selection_data A gtk.TreeDragSource is an interface that provides for the management of the source data for a gtk.TreeView drag and drop operation. row_draggable path path : the row from which the user is initiating a drag Returns : True if the row can be dragged The row_draggable() method asks the gtk.TreeDragSource if the row specified by path can be used as the source of a DND operation. If the gtk.TreeDragSource doesn't implement this interface, the row is assumed draggable. drag_data_delete path path : the row that was being dragged Returns : True if the row was successfully deleted The drag_data_delete() method asks the gtk.TreeDragSource to delete the row specified by path, because it was moved somewhere else via drag-and-drop. This method returns False if the deletion fails because path no longer exists, or for some other model-specific reason. drag_data_get path selection_data path : the row that was dragged selection_data : a gtk.SelectionData to fill with data from the dragged row Returns : True if data of the required type was provided The drag_data_get() method asks the gtk.TreeDragSource to fill in the selection data object specified by selection_data with a representation of the row specified by path. The selection_data target attribute gives the required type of the data.
