I (slowly) make my self acquainted with drag/drop via a
tic/tac/toe game.
3x3 squares where I can drop X:es or O:s where the
square is free. (Not done yet)
But I find it useful to set up these callbacks
-- set source
procedure Start_Drag
procedure End_Drag
-- set target
procedure Enter_Drag
-- clear target
procedure Leave_Drag
-- execute on target
procedure Drop (Object : in out Gnoga.Gui.Base.Base_Type'Class;
Drag_Text : in String ) ;
and see in what order they are fired,
and save info in the app-specific data structure - my_app
