NAMEglutReshapeFunc — Sets the Reshape callback for the current window.
LIBRARY
OpenGLUT - windowcallback
SYNOPSIS
#include <openglut.h>
void
glutReshapeFunc(void( *callback )( int w, int h ));
PARAMETERS
callback Client function for reshape-window event.
DESCRIPTION
This registers a function with OpenGLUT, which OpenGLUT will invoke when‐
ever the window is reshaped or resized. Your callback is only invoked
when the host window system has actually changed the window size.
The parameters to your callback are the new width and height for your
window.
If you do not provide a reshape callback, OpenGLUT will simply call
glViewport(0,0, w, h).
This callback is bound to the current window .
To ask OpenGLUT about the present dimensions of the current window ,
you can use glutGet().
CAVEATS
Unlike other callbacks, GLUT has an active default behavior if you do
not set this. (Most event types passively do nothing if you do not
specify a callback to handle them.)
The reshape callback should always be called, if registered, when your
window is first created.
