Hello!
After 2 years of experiments on GL+Win32
I’m developing an Fantasy RPG, with OpengGL
rendering the world on a view window, and MFC managing my GUI.
Now:
I overridden my CGLRpgApp::Run() and added
code to refresh my GL (wglMakCurrent,Draw,SwapBuffers) and it seemed the application caught an endless loop drawing on and on blocking the GUI managing.
the code is:
ASSERT_VALID(this);
// for tracking the idle time state
BOOL bIdle = TRUE;
LONG lIdleCount = 0;
// acquire and dispatch messages until a WM_QUIT message is received.
for (; [img]http://www.opengl.org/discussion_boards/ubb/wink.gif[/img]
{
// phase1: check to see if we can do idle work
while (bIdle &&
!::PeekMessage(&m_msgCur, NULL, NULL, NULL, PM_NOREMOVE))
{
// call OnIdle while in bIdle state
if (!OnIdle(lIdleCount++))
bIdle = FALSE; // assume "no idle" state
}
// phase2: pump messages while available
do
{
// pump message, but quit on WM_QUIT
if (!PumpMessage())
return ExitInstance();
// reset "no idle" state after pumping "normal" message
if (IsIdleMessage(&m_msgCur))
{
bIdle = TRUE;
lIdleCount = 0;
}
//HERE ADDED CODE
wglMakCurrent(…);
glClear();// just a blackened window
SwapBuffers(…);
wglMakCurrent(NULL,NULL);
} while (::PeekMessage(&m_msgCur, NULL, NULL, NULL, PM_NOREMOVE));
}
ASSERT(FALSE); // not reachable
