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.
