Controls

Controls are graphic objects that cause instant actions or visible results when the user manipulates them with the mouse. Standard controls include push buttons, scroll bars, radio buttons, checkboxes, sliders, and pop-up menus.

For Carbon developers, the Control Manager determines the overall appearance of all controls. For Cocoa developers, the overall appearance of interface elements is provided by the Application Kit. You are responsible for positioning the controls within your windows, according to the guidelines given here.

For implementation information, Carbon developers should see Inside Mac OS X: Handling Carbon Windows and Controls, available on the Mac OS X developer documentation website.
