Message Override Functions for Customizing QuickDraw GX Dialog Boxes

To install an override function for a message, you need to call the GXInstallApplicationOverride function. Within the GXInstallApplicationOverride function, you specify a pointer to a function that you use to override a particular message for a specific dialog box. These messages include

• gxJobPrintDialog
• gxJobDefaultFormatDialog
• gxFormatDialog
• gxHandlePanelEvent
• gxFilterPanelEvent
• gxParsePageRange

You can use dialog box messages to invoke your actions. QuickDraw GX sends the gxJobDefaultFormatDialog message when your application calls GXJobDefaultFormatDialog to display the Page Setup dialog box. QuickDraw GX sends the gxFormatDialog message when your application calls GXFormatDialog to display the Custom Page Setup dialog box and it sends the gxJobPrintDialog message when your application calls GXJobPrintDialog to display the Print dialog box.

QuickDraw GX also sends the gxHandlePanelEvent message and the gxFilterPanelEvent message when an event occurs in a panel.
