(the first on Windows 10 the second on Linux Ubuntu). I want both computers capable of running my programs even if I define a the window on 2000 * 1200 for a Gtk project. On the computer that can handle the resolution the there is of course no problem. On the other the screen is window is to big for the resolution and is shown only partly (of course). My question is: Is there an Ada library that is able to somehow read the  maximum sizes of the screen in pixels so I can firstly maximize my values for size definition in Gtk. I already tried: Maximize(Mainwindow); Get_Size(MainWindow, Height, Width); The result was 200 * 200
