Hi at all,
in windows i use this code to detect position of windows' taskbar:

Code: [Select]var
  hWndTaskbar: HWND;
  TaskbarRect: TRect;
begin
    { First we get the Taskbar window and it's screen position }
    hWndTaskbar := FindWindow('Shell_TrayWnd', nil);
    if hWndTaskbar = 0 then Exit;
    Windows.GetWindowRect(hWndTaskbar, @TaskbarRect);

    //Memo1.Lines.Add(TaskbarRect.Top);
    //Memo1.Lines.Add(TaskbarRect.Bottom);
    //Memo1.Lines.Add(TaskbarRect.Left);
    //Memo1.Lines.Add(TaskbarRect.Right);
end;

Someone knows how do the same on Linux???

Thanks, Mario

Why do you need this? I would avoid it if you can. I beliave it will
be hard.

A possible solution would be creating a system tray icon with
TTrayIcon and then call TTrayIcon.Position. With this position you can
easely calculate the taskbar position, but you need a visible tray
icon.

I want center a form in the screen and poScreenCenter don't consider
the TaskBar so, on a PC with the TaskBar very high the form is not on
center of the screen
