NAME

     glutCreateMenuWindow -- Create a client-controlled menu window.

LIBRARY

     OpenGLUT - experimental

SYNOPSIS

     #include <openglut.h>

     int
     glutCreateMenuWindow(int parentID, int x, int y, int w, int h);

PARAMETERS

      parentID	   Parent window identifier.

      x 	   Horizontal coordinate on the screen.

      y 	   Vertical coordinate on the screen.

      w 	   Width of the new window.

      h 	   Height of the new window.

DESCRIPTION

     This is a highly experimental function.  It creates a menu-like window, of requested dimensions, and at a position relative to your current
     window.

     The documentation for this function is currently the OpenGLUT Menu Window proposal.  Variance from that proposal may generally be explained
     by the fact that this feature is highly experimental.  It may also be explained by the fact that the implementation may simply be incomplete.

CAVEATS

     Did you notice that this feature is highly experimental?

NAME

     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.
