How to get the screen size?

How to get the screen size?

[tolkamp]

To make my ada application program suitable for more monitor sizes, I need the Screen Size. Where the size is the number of pixels.
Is there a function or procedure to get the screen width and height?

On which monitor, under which OS?
CLAW (Class Library for Ada on Windows) has Get_System_Metrics, which
basically calls Windows' GetSystemMetrics with the right parameter.

There are multiple ways to do this. Are you in a browser, under Ncurses or inside a GUI? You can also get this directly from X assuming your not on Windows

My ADA application program uses JEWL packages.
The OS is Windows 7.

Does JEWL provide this information?

Anyway, if your application is limited to Windows already, there is no
reason not to use Win32Ada.

You call GetDesktopWindow from the package Win32.Winuser, which gives you a
handle to the desktop window. Then you call GetWindowRect on that window.
The rectangle returned is one of the desktop. For further information see
MSDN:

Note than Windows supports multiple monitors. You could wish to enumerate
them. See GetMonitorInfo in MSDN.
