UNTITLED
LOCAL UNTITLED
NAME
glutDisplayFunc -- Sets the Display callback for the current window.
LIBRARY
OpenGLUT - windowcallback
SYNOPSIS
#include <openglut.h> void glutDisplayFunc(void( *callback )( void ));
PARAMETERS
callback Client function for normal redisplay event.
DESCRIPTION
Sets the display callback for the current window . All windows, including subwindows, must have a display callback registered. OpenGLUT will call the callback function whenever it thinks that the window may require updating. This callback is bound to the current window .
CAVEATS
Unlike most callbacks, it is illegal to try to disable the display callback by setting it to NULL . Multiple redisplays may be coalesced into a single event for invoking the callback only once.
