glx_viewport(3Tk)glx_viewport(3Tk)NAMEglx_viewport - configure the GL viewport
SYNOPSISglx_viewport width height
glx_viewport left right bottom top
DESCRIPTIONglx_viewport calls the GL function viewport(). If two arguments are
given, they are assumed to be the width and height of a viewport whose
origin is at (0, 0). If four arguments are given, they represent the
left, right, bottom and top of the viewport.
Whenever a Configure event is received in a glxwin window, this command
should be called as glx_viewport %w %h to notify GL of the new size of
the window. The change in viewport applies to the current window only;
if other windows or auxiliary windows (such as overlays and popups) are
in use, each should be selected in turn and glx_viewport should be
called.
