glutShowWindow, glutHideWindow, glutIconifyWindow - change the display status of
the current window.
void glutShowWindow(void);
void glutHideWindow(void);
void glutIconifyWindow(void);
glutShowWindow will show the current window (though it may still not be visible
if obscured by other shown windows). glutHideWindow will hide the current
window. glutIconifyWindow will iconify a top-level window, but GLUT prohibits
iconification of a subwindow. The effect of showing, hiding, and iconifying
windows does not take place immediately. Instead the requests are saved for
execution upon return to the GLUT event loop. Subsequent show, hide, or
iconification requests on a window replace the previously saved request for
that window. The effect of hiding, showing, or iconifying top-level windows is
subject to the window system's policy for displaying windows.
glutPopWindow, glutPushWindow
