CTabChanged

CTabChanged
Header:	QDOffscreen.h		Carbon status:	Supported

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

void CTabChanged (
    CTabHandle ctab
);

Parameter descriptions

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.

AVAILABILITY

Supported in Carbon. Available in Carbon 1.0.2 and later when running Mac OS 8.1 or later.
