NAME

       glutReshapeFunc - sets the reshape callback for the current window.

SYNTAX

       void glutReshapeFunc(void (*func)(int width, int height));

ARGUMENTS

       func	 The new reshape callback function.

DESCRIPTION

       glutReshapeFunc	sets  the  reshape callback for the current window. The reshape callback is triggered when a window is reshaped. A reshape
       callback is also triggered immediately before a window's first display callback after a window is created or whenever an  overlay  for  the
       window is established. The width and height parameters of the callback specify the new window size in pixels. Before the callback, the cur-
       rent window is set to the window that has been reshaped.

       If a reshape callback is not registered for a window or NULL is passed to glutReshapeFunc (to deregister a previously registered callback),
       the  default  reshape callback is used. This default callback will simply call glViewport(0,0,width,height) on the normal plane (and on the
       overlay if one exists).

       If an overlay is established for the window, a single reshape callback is generated. It is the callback's responsibility to update both the
       normal plane and overlay for the window (changing the layer in use as necessary).

       When  a top-level window is reshaped, subwindows are not reshaped. It is up to the GLUT program to manage the size and positions of subwin-
       dows within a top-level window. Still, reshape callbacks will be triggered for subwindows when their size is changed using  glutReshapeWin-
       dow.
