Control Manager Reference

Your program can use the Control Manager to create and manage controls. Controls are onscreen objects that the user can manipulate with the mouse. By manipulating controls, the user can take an immediate action or change settings to modify a future action.

Portions of the Control Manager application programming interface (API) are new, changed, or not recommended with Mac OS 8 or Appearance Manager 1.0. See the following sections for descriptions of the changes to the Control Manager:

• Control Manager Functions
• Control Manager Data Types
• Control Manager Constants
• Result Codes

For descriptions of the parts of the Control Manager API that are unaffected by Appearance Manager 1.0, see Inside Macintosh: Macintosh Toolbox Essentials . For a description of the Mac OS 8.5 Control Manager API, see Mac OS 8.5 Control Manager Reference .
