minimizing gl window
Author
Why is it so, that when i minimize gl windows from the tutorials processor usage raises to 100%??
The processor should be at 100% while the program is running. When you minimize it you''ve not changed anything.

i''m a very beginner so i might be wrong but there is [active] variable which determines if program is active or not. When [active] is zero no drawing is being performed ( i understand it this way ) :
//if ((active && !DrawGLScene()) || keys[VK_ESCAPE])//
( assuming that checking conditions is done from left to right, doesn''t it? )
so what''s going on with that processor usage?
btw: when window is active my processor usage is about 5% but when i minimize it usage raises to 100%
Something must be wrong but what?

Actually it has, why render if the app is minimized? What changed is the user minimized for a reason and the reason isn''t to have the app still rendering.
l_ahriman:
It should be something like this:
In your message procedure have something like this:
case WM_ENTERSIZEMOVE: Active = false; break;//case WM_SIZE: if(Windowed) { if(wParam == SIZE_MAXHIDE || wParam == SIZE_MINIMIZED) { Active = false; } else { Active = true; } } break;//case WM_EXITSIZEMOVE: Active = true; break;Then in the message pump have something like this:
BOOL RecievedMessage;MSG Message;PeekMessage(&Message, NULL, 0U, 0U, PM_NOREMOVE);while(Message.message != WM_QUIT){ if(Active) { RecievedMessage = PeekMessage(&Message, NULL, 0U, 0U, PM_REMOVE); } else { RecievedMessage = GetMessage(&Message, NULL, 0U, 0U); }// if(RecievedMessage) { TranslateMessage(&Message); DispatchMessage(&Message); } else { if(Active) { Render(); } else { WaitMessage(); } }}//return (int)Message.wParam;That should take it to 0% when the app gets minimized.

Yes, it checks each condition from left to right. What your basically saying is:
"If my application is active and rendering the current scene returned false or the escape key was pressed then ...(Close the application?)"
