glutmenustatusfunc(3) - Linux man page

Name

glutMenuStatusFunc - Modern variant of glutMenuStateFunc()

Library

OpenGLUT - menucallback

Synopsis

#include <openglut.h>

void

glutMenuStatusFunc(void( *callback )( int status, int x, int y ));

Parameters

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

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

This callback is bound to both the current window and the current menu .

Bugs

Your callback is not actually called presently.
