PortChanged

#include <QDOff screen.h> Color QuickDraw

void PortChanged(port);

GrafPtr port; a pointer to a grafPort

Call PortChanged after modifying the content of a grafPort or any of its

sub structures. PortChanged notifies QuickDraw of the change.

port a grafPort pointer

Notes: You should not directly change any of the pixel pattern records pointed to

by a color grafPort record. Instead, use the PenPixPat and BackPixPat

procedures. However, if your application changes the content of one of the

pixel pattern records, it should call PixPatChanged.

If your application changes the pmTable field of the port's pixel map, it

should call PortChanged. However, if your application changes the content

of the color table referenced by pmTable, it should call CTabChanged as

well.
