How to create a window that is centered?

Recommended Posts

Hello, I''m just getting started with programming for Windows in C++, eventually hoping to learn DirectX and make a game. Anyway, when creating a window, I know you can use CW_USEDEFAULT when setting up where the window will be to use the default location, but I was wondering if there is a simple way to have the window be centered. Also, is there a good place to look up all the useful definitions such as CW_USEDEFAULT and the many others? Thanks, Beau

You can get the screen width and height using GetSystemMetrics() and do the math from there:
cx = screen_width/2;
cy = screen_height/2;
min_x = cx - (window_width/2), max_x = cx + (window_width/2);
min_y = cy - (window_height/2), max_y = cy + (window_height/2);

You now use min_x, min_y, max_x and max_y as your window dimensions.

I wanna work for Microsoft!

if you are creating the window, i''ll assume you know the width and height of the window you are creating.
  RECT rect;GetWindowRect(GetDesktopWindow(), &rect);//in the CreateWindow function call, for the x and y://x:(rect.right >> 1) - WINDOW_WIDTH// or if you don''t like shifting (this does the same thing)(rect.right / 2) - WINDOW_WIDTH//y:(rect.bottom >> 1) - WINDOW_HEIGHT// same as above(rect.bottom / 2) = WINDOW_HEIGHT
