Topic: Class Wrapper and Function References
Conf: (P-PDF) Developers, Msg: 88762

I'm trying to add a class wrapper to the sample code for adding a
menu item. It is important to store a reference to the function which
will be called when the menu item is executed. There are similar
arrangements for marking and enabling, which I have left out for
clarity. Essentially it consists of the following code snippets:

Declaration:

AVExecuteProc ExecProcPtr;

Defining the reference:

ExecProcPtr = ASCallbackCreateProto (AVExecuteProc, &ExecProc);

Setting the reference:

AVMenuItemSetExecuteProc (NewItem, ExecProcPtr, NULL);

The actual procedure to be called:

ACCB1 void ACCB2 ExecProc (void* data) { ..... }

In adding a class wrapper, I've moved the declaration into the
declaration for the class. The procedure to be called changed from
ExecProc to Classname::ExecProc. The actual function, once the
class has been instantiated, will effectively become this.ExecProc.

The question is, what will the reference become? I've tried the
obvious &this.ExecProc and &this->ExecProc, but get various syntax
errors. 'this' is itself a reference, equivalent to &instance, so I've
also tried without the '&', and even without 'this', which ought to be
implied.

Does anyone have any bright ideas?

Many TIA!
