Mac OS 8 Dialog Manager Reference

Defining Your Own Dialog Item Function

When the Appearance Manager is available and an embedding hierarchy is established in a dialog box, you should provide the Control Manager user pane drawing function MyUserPaneDrawProc instead of the user item drawing function MyUserItemProc to draw an application-defined control (a dialog item becomes a control in a dialog box with an embedding hierarchy).

You can provide other user pane application-defined functions to hit test, track, perform idle processing, handle keyboard, activate, and deactivate event processing, handle keyboard focus, and set the background color or pattern in a user pane control. For examples of how to write these functions, see Mac OS 8 Control Manager Reference .
