我发现freeglut全屏效果很好，即使在托管基于着色器的opengl应用程序里面也是如此。 这里是被调用的内部代码(X11分支......)。 HTH

fgStructure.CurrentWindow->State.Height = win->State.OldHeight;

} else {

/* resize the window to cover the entire screen */

XGetWindowAttributes(fgDisplay.Display,

fgStructure.CurrentWindow->Window.Handle,

&attributes);

/*
