41 * All of the callbacks setting methods can be generalized to this:
43 #define SET_CALLBACK(a) if( fgStructure.Window == NULL ) return;\
44 fgStructure.Window->Callbacks.a = callback;
47 * Sets the Display callback for the current window
49 void FGAPIENTRY glutDisplayFunc( void (* callback)( void ) )
51 SET_CALLBACK( Display );
55 * Sets the Reshape callback for the current window
57 void FGAPIENTRY glutReshapeFunc( void (* callback)( int, int ) )
59 SET_CALLBACK( Reshape );
63 * Sets the Keyboard callback for the current window
65 void FGAPIENTRY glutKeyboardFunc( void (* callback)( unsigned char, int, int ) )
67 SET_CALLBACK( Keyboard );
71 * Sets the Special callback for the current window
73 void FGAPIENTRY glutSpecialFunc( void (* callback)( int, int, int ) )
75 SET_CALLBACK( Special );
79 * Sets the global idle callback
81 void FGAPIENTRY glutIdleFunc( void (* callback)( void ) )
83 freeglut_assert_ready;
86 * The global idle callback pointer is stored in fgState structure
88 fgState.IdleCallback = callback;
92 * Sets the Timer callback for the current window
94 void FGAPIENTRY glutTimerFunc( unsigned int timeOut, void (* callback)( int ), int timerID )
98 freeglut_assert_ready;
101 * Create a new freeglut timer hook structure
103 timer = calloc( sizeof(SFG_Timer), 1 );
106 * Remember the callback address and timer hook's ID
108 timer->Callback = callback;
112 * When will the time out happen (in terms of window's timer)
114 timer->TriggerTime = fgElapsedTime() + timeOut;
117 * Have the new hook attached to the current window
119 fgListAppend( &fgState.Timers, &timer->Node );
123 * Sets the Visibility callback for the current window.
125 * I had to peer to GLUT sources to clean up the mess.
126 * Can anyone please explain me what is going on here?!?

168 void FGAPIENTRY glutJoystickFunc( void (* callback)( unsigned int, int, int, int ), int pollInterval )
170 SET_CALLBACK( Joystick );
172 freeglut_return_if_fail( fgStructure.Window != NULL );
175 * Do not forget setting the joystick poll rate
177 fgStructure.Window->State.JoystickPollRate = pollInterval;
180 * Make sure the joystick polling routine gets called as early as possible:
182 fgStructure.Window->State.JoystickLastPoll =
183 fgElapsedTime() - fgStructure.Window->State.JoystickPollRate;
185 if( fgStructure.Window->State.JoystickLastPoll < 0 )

241 fgState.MenuStateCallback = callback;
245 * Sets the global menu status callback for the current window
247 void FGAPIENTRY glutMenuStatusFunc( void (* callback)( int, int, int ) )
249 freeglut_assert_ready;
