Signals QuickDraw that the content of a ColorTable structure has been modified.

void CTabChanged (
    CTabHandle ctab
);

ctab

A handle to the ColorTable structure changed by your application.

DISCUSSION

The CTabChanged function calls the function GetCTSeed and gets a new, unique identifier in the ctSeed field of the ColorTable structure, and notifies QuickDraw of the change.

Your application should never need to directly modify a ColorTable structure and use the CTabChanged function; instead, your application should use the QuickDraw functions provided for manipulating the values in a ColorTable structure.

SPECIAL CONSIDERATIONS

The CTabChanged function may move or purge memory in the application heap; do not call the CTabChanged function at interrupt time.
