UNTITLED
LOCAL UNTITLED NAME
glutTimerFunc -- Sets the Timer callback for the current window. LIBRARY
OpenGLUT - idletimer SYNOPSIS
#include <openglut.h> void glutTimerFunc(unsigned int msec, void( *callback )( int data ), int data); PARAMETERS
msec Milliseconds till invocation. callback Client function for timer event. data Arbitrary data; passed to callback . DESCRIPTION
After at least msec milliseconds, OpenGLUT will call callback , passing in your user-supplied data parameter. OpenGLUT will call your function only once. This callback is not bound to any window. CAVEATS
Unlike most other callbacks, timers only occur once. Unlike most other callbacks, you cannot deregister a timer callback. Unlike most other callbacks, you can register an arbitrary number of timers. SEE ALSO

glutMouseFunc -- Sets the mouse-button callback for the current window. LIBRARY
OpenGLUT - input SYNOPSIS
#include <openglut.h> void glutMouseFunc(void( *callback )( int button, int state, int x, int y )); PARAMETERS
callback Client hook for mouse-buttons. DESCRIPTION
Whenever a mouse button is pressed or released in an OpenGLUT window, OpenGLUT checks if that window has a mouse-button (Mouse) callback reg- istered. If so, OpenGLUT gives the event to the handler. button is the button number, starting from 0. state is GLUT_UP or GLUT_DOWN to indicate the button's new state. The other parameters are the mouse coordinates. Mouse wheel motion can be reported as buttons. If you do not request otherwise, a wheel spun forward will act like a button clicking down, immediately followed by clicking up. Spinning the same wheel backward will act like a different button clicking. Mouse wheel pseudo-buttons are added after all real buttons. While the button is held and the mouse is dragged, you receive mouse-motion events (glutMotionFunc()), even if the mouse is dragged out of the window. This callback is bound to the current window . CAVEATS
Reporting the wheel as buttons is actually inherited from X. freeglut added code to support this on WIN32. OpenGLUT inherited that support from freeglut. Old GLUT defines the symbols GLUT_LEFT_BUTTON, GLUT_RIGHT_BUTTON, and GLUT_MIDDLE_BUTTON. However, mice can have more than 3 buttons, so these symbols are deprecated. Windows created via glutCreateMenuWindow() always cascade keyboard and mouse events to their parent. SEE ALSO
