Question

Is there a way to change the maximum size of a possibly maximized window, without changing the maximization state of the window? (I’m referring toMINMAXINFO.ptMaxSize and MINMAXINFO.ptMaxTrackSize here.)

Or, in other words: How do I tell the system to send my window a WM_GETMINMAX and refresh its state as necessary?

Answer 1

I actually think I found a solution:

SetWindowPos(
    hWnd, NULL, rect.left, rect.top, rect.width, rect.height,
    SWP_NOACTIVATE | SWP_NOOWNERZORDER | SWP_NOZORDER);
