Check if window is full screen in c++?
Author
I'm trying to make a command that can check if my window is full screen. I use ChangeDisplaySettings with CDS_FULLSCREEN to change the window to full screen, and I could set a bool to tell when the window is full screen but it would make my code a bit cleaner if I could simply read the display settings. Is this possible?
RECT windowRect;
GetClientRect(HWND, &windowRect);
windowRect.left == 0 && windowRect.top == 0 && windowRect.right == GetSystemMetrics(SM_CXSCREEN) && windowRect.bottom == GetSystemMetrics(SM_CYSCREEN) <--- if true, your window in 'fullscreen' mode...
P.S. Do not change REFRESH_RATE of the screen in ChangeDisplaySettings (If you using that option). Better to keep it by default.
EDIT0:
Or you can determine by style of your window :
(GetWindowLong(HWND,GWL_STYLE) & WS_POPUP != 0) <-- if true, your window in 'fullscreen' mode...
if you are using 'frame' style of your window in 'windowed' mode.
end of EDIT0.
Best wishes, FXACE.
