SYNOPSIS

In openglut.h Ft void Fn glutMenuDestroyFunc void( *callback )( void )  

PARAMETERS

Bf Em
 callback Ef
    Client menu destruction hook.  

DESCRIPTION

When a menu is destroyed, OpenGLUT will call this hook, if defined on that menu.

This callback is Bf Em
 not Ef
  bound to any window.

This callback Bf Em
 is Ef
  bound to a specific menu.

 

CAVEATS

For emphasis, we repeat: This callback does not bind to any window.

 

TODO

What on Earth is rationale for this feature? Menus should only be destroyed when we ask them to be destroyed, or when their window is destroyed. In the former case, we already know that the menu is being destroyed because we requested it. In the latter case, it is easy for the client to track that if they care, via window-destruction callbacks.
