glutMenuStatusFunc (3) Linux Manual Page

glutMenuStatusFunc – Modern variant of glutMenuStateFunc()

Library

OpenGLUT – menucallback

Synopsis

In openglut.h Ft void Fn glutMenuStatusFunc void( *callback )( int status int x int y )

Parameters

Bf Em
 callback Ef
    Client menu status hook.

Description

Broadly, OpenGLUT operates in two modes. At any given time, it is either in menu mode (with a popup menu display, possibly with subitems) or it is not.

When moving from non-menu to menu status, Bf Sy
 callback Ef
 (if defined) will be called with Bf Sy
 GLUT_MENU_IN_USE Ef
 .  Conversely, when moving from menu to non-menu status, Bf Sy
 callback Ef
 (if defined) will be called with Bf Sy
 GLUT_MENU_NOT_IN_USE Ef
 .

This differs from glutMenuStateFunc() in that Bf Sy
 callback Ef
 is also given the  Bf Sy
 x Ef
 and  Bf Sy
 y Ef
  coordinates of the mouse when the menu state transition took place.

This callback is bound to Bf Em
 both Ef
  the Bf Li
 current window Ef
  and the Bf Li
 current menu Ef
 .

Bugs

Your callback is not actually called presently.
