glutReshapeFunc(3GLUT) GLUT glutReshapeFunc(3GLUT)NAMEglutReshapeFunc - sets the reshape callback for the cur
rent window.
SYNTAX
void glutReshapeFunc(void (*func)(int width, int height));
ARGUMENTS
func The new reshape callback function.
DESCRIPTIONglutReshapeFunc 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 estab
lished. The width and height parameters of the callback
specify the new window size in pixels. Before the call
back, the current 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 previ
ously registered callback), the default reshape callback
is used. This default callback will simply call glView
port(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 subwindows within a top-level window.
Still, reshape callbacks will be triggered for subwindows
when their size is changed using glutReshapeWindow.
