Event Handler for the Combo Box

Jun 29, 2009 1:03 AM

Hi,

 

I have TextComboBoxWidget, I want to trap the return key event. For each key press the update function in Observer get exectued but I found the difference in only ClassID when the focus is lost,

 

I tried to write the event handler,

code in  .fr file is as

Class
    {
        kMyComboBoxWidgetBoss,
        kTextComboBoxWidgetBoss,
        {
            IID_IEVENTHANDLER,  kMyComboBoxEHImpl,
            IID_IMYCOMBOEVENTHANDLER,  kComboBoxEventHandlerImpl ,
        }
    },

type MyTextComboBoxWidget(kViewRsrcType) : TextComboBoxWidget(ClassID = kMyComboBoxWidgetBoss){};

 

In factory.h the class is registered.

 

And kMyComboBoxEHImpl is inherited from the CEventHandler, as

class EditBoxEH2 : public CEventHandler

 

but, when I press any then the control is not comming in the constructor of the event handler, I am not getting what's going wrong?  Please help.

 

Thanks,

Praveen
