enum { kControlPushButtonProc = 368, kControlCheckBoxProc = 369, kControlRadioButtonProc = 370, kControlPushButLeftIconProc = 374, kControlPushButRightIconProc = 375 };
Resource ID: 23
Appearance-compliant push button.This control definition is new with the Appearance Manager and is not supported unless the Appearance Manager is available.
Resource ID: 23
Appearance-compliant checkbox. This control definition is new with the Appearance Manager and is not supported unless the Appearance Manager is available.
Resource ID: 23
Appearance-compliant radio button. This control definition is new with the Appearance Manager and is not supported unless the Appearance Manager is available.
Resource ID: 23
Appearance-compliant push button with a color icon to the left of the control title. (This direction is reversed when the system justification is right to left). The contrlMax field of the control structure for this control contains the resource ID of the 'cicn' resource drawn in the pushbutton. This control definition is new with the Appearance Manager and is not supported unless the Appearance Manager is available.
Resource ID: 23
Appearance-compliant push button with a color icon to right of control title. (This direction is reversed when the system justification is right to left). The contrlMax field of the control structure for this control contains the resource ID of the 'cicn' resource drawn in the pushbutton. This control definition is new with the Appearance Manager and is not supported unless the Appearance Manager is available.
When creating a control, your application supplies a control definition ID to one of the Control Manager control-creation functions or to the control resource; see 'CNTL'. The control definition ID indicates the type of control to create. A control definition ID is an integer that contains the resource ID of a control definition function in its upper 12 bits and a variation code in its lower 4 bits. A control definition ID is derived as follows:
control definition ID = 16 * ('CDEF' resource ID) + variation code
A control definition function determines how a control generally looks and behaves. Control definition functions are stored as resources of type 'CDEF'. Various Control Manager functions call a control definition function whenever they need to perform some control-dependent action, such as drawing the control on the screen. For more information on how to create a control definition function, see Defining Your Own Control Definition Function.
A control definition function, in turn, can use a variation code to describe variations of the same basic control. For example, all pop-up arrows share the same basic control definition function, which is stored in a resource of type 'CDEF' and has a resource ID of 12. The standard pop-up arrow is large and points to the right; it has a control definition ID of 192. A variation of this is a large, left-pointing arrow, which has a control definition ID of 193. Still another variation, in which the arrow points up, has a control definition ID of 194.
Your application can use the constants listed here in place of control definition IDs.
If your application contains code that uses the older, pre-Appearance control definition IDs or their constants, your application can use the Appearance Manager to map the old IDs to those for the new, updated controls introduced by the Appearance Manager. In particular, the control definition IDs for pre-Appearance checkboxes, buttons, scroll bars, radio buttons, and pop-up menus will be automatically mapped to Appearance-compliant equivalents.
