Because your function is not an independent functions but rather a public
functions withing a class and CW is having trouble with it. you need to
include the app event loop and the apphandleevent into your class and then
you should be able to use the callback event handler from within your class
hope this helps

Subject: FrmSetEventHandler
Date: Wed, 25 Jul 2007 15:39:08 -0000
So im having a little bit of trouble with the FrmSetEventHandler(FormType
*formP, FormEventHandlerType *handler). I am trying to add a new form to
some code and I want to give it a event handler. Looking through the code
I see this function used in two ways.
FrmSetEventHandler(frmP, (FormEventHandlerType *)
&(QForm::EventDispatcher));
and
extern Boolean MainFormHandleEvent(EventPtr eventP);
FrmSetEventHandler(frmP, MainFormHandleEvent);
I have tried to add my own form handler with
FrmSetEventHandler(frmP, (FormEventHandlerType *)
&(QForm::HandleEvent));
and
extern Boolean QForm::HandleEvent(EventPtr eventP);
FrmSetEventHandler(frmP, QForm::HandleEvent);
in both cases I get:
Error : illegal explicit conversion from 'void' to
'unsigned char (*)(struct EventType *)'
QForm.cpp line 280 FrmSetEventHandler(frmP, (FormEventHandlerType *)
&(QForm::HandleEvent));
Why are the other calls working and why can I not get mine to compile
