Inside Macintosh: More Macintosh Toolbox /

Chapter 8 - Control Panels

Control Panels Reference

This section describes the application-defined routines and the resources that are specific to control panels and extensions to the Monitors control panel.

The section "Application-Defined Routines" describes the control device function that you must provide for a control panel and the monitors extension function that you must provide for an extension to the Monitors control panel. You create a control device function to implement a control panel. A control device function should respond to messages from the Finder, handling any events or performing any actions as requested by the Finder. A monitors extension function extends the Monitors control panel to provide support for a video device so that users can control its settings.

The "Resources" section lists the resources required for a control panel or an extension to the Monitors control panel. It includes specific sections for the resources you must supply for a control panel or a monitors extension if those resources are not fully documented elsewhere in Inside Macintosh, and it indicates where to find information about required resources that are not covered in that section.
