ThemeIteratorUPP

The Appearance Manager defines the type for an application-defined theme iteration function as follows:



 
typedef pascal (Boolean, ThemeIteratorProcPtr) (

                     ConstStr255Param inFileName,

                     SInt16 resID,

                     Collection inThemeSettings,

                     void *inUserData);

The Appearance Manager defines the data type ThemeIteratorUPP to identify the universal procedure pointer for an application-defined theme iteration function:



 
typedef ThemeIteratorProcPtr ThemeIteratorUPP;

You typically use the NewThemeIteratorProc macro like this:



 
ThemeIteratorUPP myThemeIteratorUPP;

myThemeIteratorUPP = NewThemeIteratorProc(MyThemeIteratorProc);

You typically use the CallThemeIteratorProc macro like this:



 
CallThemeIteratorProc(myThemeIteratorUPP, inFileName, resID, inThemeSettings, 

inUserData);

To implement your own theme iteration function, see MyThemeIteratorProc . The ThemeIteratorProcPtr type is available with Appearance Manager 1.1 and later.
