NAME
glutReshapeFunc
- Sets the Reshape callback for the current window.
LIBRARY
OpenGLUT - windowcallback
SYNOPSIS
In openglut.h
Ft void
Fn glutReshapeFunc void( *callback )( int w int h )
PARAMETERS
Bf Em
callback
Ef
Client function for reshape-window event.
DESCRIPTION
This registers a function with OpenGLUT, which OpenGLUT
will invoke whenever 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,
Bf Sy
w,
Ef
Bf Sy
h).
Ef
This callback is bound to the
Bf Li
current window
Ef
.
To ask OpenGLUT about the present dimensions of the
Bf Li
current window
Ef
, you can use glutGet().
CAVEATS
Unlike other callbacks, GLUT has an
Bf Em
active
Ef
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.
