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.
