  Source	Destination
  Setup source define a source target list using GtkTargetEntry call gtk_drag_source_set() connect handlers or use vfuncs or use default handlers it's also possible to start a drag manually using a GtkTargetList and calling gtk_drag_begin_with_coordinates()	Setup destination define a destination target list using GtkTargetEntry call gtk_drag_dest_set() connect handlers or use vfuncs or use default handlers
  1 - "drag-begin" Drag operation triggered set the drag icon setup of the current drag	2 - "drag-motion" Cursor moves over the drop target, the handler is called for each cursor movement hightlight the drop zone can examine drag format and drag action : call gtk_drag_dest_find_target() <-- "drag-data-get" drop impossible : call gtk_drag_status(context, 0, time) return false drop possible : call gtk_drag_status(context, action, time) return true
  4 - "drag-data-get" Data requested from a drop destination prepare data depending on the target send data to the selection object : call gtk_selection_data_set() --> "drag-data-received"	3 - "drag-drop" Button released over destination check for a correct sub-drop zone examine drag format and drag action drop rejected : return false - drop accepted : gtk_drag_get_data() <-- "drag-data-get" return true
  "drag-failed" end the DnD operation free resources --> "drag-end"	5 - "drag-data-received" Button release over destination get the data received : gtk_selection_data_get() data rejected : call gtk_drag_data_finish(false) <-- "drag-failed" data accepted : copy data free destination resources call gtk_drag_data_finish(true, delete) <-- "drag-data-delete" <-- "drag-end"
  "drag-data-delete" delete the moved data --> "drag-end"
  "drag-end" end the DnD operation free resources
