GXPrClosePage

QuickDraw GX sends the GXPrClosePage message when an application that supports the Macintosh Printing Manager calls the PrClosePage function. You can override the GXPrClosePage message to customize the handling of the PrClosePage function. Your override of the GXPrClosePage message must match the following formal declaration:

OSErr GXPrCloseDoc (TPPrPort aTPPrPort);

aTPPrPort

A pointer to a TPPrPort record.

function result

An error code. The value noErr indicates that the operation was successful.

DESCRIPTION

The default implementation of this message generates the GXFinishPage message. You can override this message to add any special handling that your driver requires at the time that a page has finished printing.

SPECIAL CONSIDERATIONS

You never send the GXPrClosePage message yourself.

You almost always forward the GXPrClosePage message so that the default implementation can perform its operations.

RESULT CODES

gxSegmentLoadFailedErr	A required code segment could not be found, or there was not enough memory to load it.
gxPrUserAbortErr	The user has canceled printing.

SEE ALSO

The PrClosePage function is described in Inside Macintosh: Imaging With QuickDraw.

The GXFinishPage message is described on page 4-57.
