glutpushwindow(3) - Linux man page
Name
glutPushWindow - Request to lower the current window to the bottom.
Library
OpenGLUT - window
Synopsis
#include <openglut.h>
void
glutPushWindow(void);
-
Description
This function requests that the current window be ''pushed'' to the back.
A window can be in front of or behind other windows, as determined by the z-order from front to back. Top-level OpenGLUT windows can be placed at the front or back of the z-order by means of the glutPopWindow() and glutPushWindow() API functions.
A z-order also applies to the subwindows of a top-level window. While the z-order of top-level windows can usually be adjusted by the user, subwindow z-order is controlled entirely by the application.
There may not be an immediate effect to this function. Wait for the glutWindowStatusFunc() callback to tell you about whatever obscured/visible status your window achieves.
Caveats
The z-order of top-level windows is ultimately managed by the windowing system. Therefore, a push or pop request by an OpenGLUT application may not necessarily succeed or take immediate effect.
Not applicable to offscreen windows.
