LIBRARY

OpenGLUT - window

SYNOPSIS

In openglut.h Ft void Fn glutShowWindow void

DESCRIPTION

glutShowWindow() requests that the window system make the Bf Li
 current window Ef
  visible.

This is generally not necessary. When you create a window, it will normally become visible. Unless you specifically hide it, it will remain visible. Though visible, of course, it may be covered by other windows; that would be an issue for window stacking order not visibility.

When, and if, your window's visibility status changes, you may find out via a glutWindowStatusFunc() callback.
