How to manage absolute coordinate window in gtk3 python -
i translated treeview gtk2 tooltip in gtk3 it's running have problem manage coordinate of tooltip window.
i tooltip window locate near mouse et follow near. instead of project tooltip window located in corner of screen
my code

you working local coordinates, need refer dialog position root coordinates. issue script main window dialog, therefore in foreground, tooltips appear below (i have fixed deleted code (oops). works, change dialog normal window). general note, widget know parent refer when root coordinates required.
