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 );
54 * Force a redisplay with the new callback
56 fgStructure.Window->State.Redisplay = TRUE;
61 * Sets the Reshape callback for the current window
63 void FGAPIENTRY glutReshapeFunc( void (* callback)( int, int ) )
65 SET_CALLBACK( Reshape );
69 * Sets the Keyboard callback for the current window
71 void FGAPIENTRY glutKeyboardFunc( void (* callback)( unsigned char, int, int ) )
73 SET_CALLBACK( Keyboard );
77 * Sets the Special callback for the current window
79 void FGAPIENTRY glutSpecialFunc( void (* callback)( int, int, int ) )
81 SET_CALLBACK( Special );
85 * Sets the global idle callback
87 void FGAPIENTRY glutIdleFunc( void (* callback)( void ) )
89 freeglut_assert_ready;
92 * The global idle callback pointer is stored in fgState structure
94 fgState.IdleCallback = callback;
98 * Sets the Timer callback for the current window
100 void FGAPIENTRY glutTimerFunc( unsigned int timeOut, void (* callback)( int ), int timerID )
104 freeglut_assert_ready;
107 * Create a new freeglut timer hook structure
109 timer = (SFG_Timer *)calloc( sizeof(SFG_Timer), 1 );
112 * Remember the callback address and timer hook's ID
114 timer->Callback = callback;
118 * When will the time out happen (in terms of window's timer)
120 timer->TriggerTime = fgElapsedTime() + timeOut;
123 * Have the new hook attached to the current window
125 fgListAppend( &fgState.Timers, &timer->Node );
129 * Sets the Visibility callback for the current window.
131 * I had to peer to GLUT sources to clean up the mess.
132 * Can anyone please explain me what is going on here?!?
