## 4.9 glutFullScreen

`glutFullScreen` requests that the current window be made full screen.

Usage

    void glutFullScreen(void);

Description

`glutFullScreen` requests that the current window be made full screen. The exact semantics of what full screen means may vary by window system. The intent is to make the window as large as possible and disable any window decorations or borders added the window system. The window width and height are not guaranteed to be the same as the screen width and height, but that is the intent of making a window full screen.

`glutFullScreen` is defined to work only on top-level windows.

The `glutFullScreen` requests are not processed immediately. The request is executed after returning to the main event loop. This allows multiple `glutReshapeWindow`, `glutPositionWindow`, and `glutFullScreen` requests to the same window to be coalesced.

Subsequent `glutReshapeWindow` and `glutPositionWindow` requests on the window will disable the full screen status of the window.

X Implementation Notes

In the X implementation of GLUT, full screen is implemented by sizing and positioning the window to cover the entire screen and posting the `_MOTIF_WM_HINTS` property on the window requesting absolutely no decorations. Non-Motif window managers may not respond to `_MOTIF_WM_HINTS`.
