Inheritance problem


I have created a new View based on CScrollView. Let us call this CMyScrollView.

From this new class I have created another view class which inherits from it e.g.

class CMyApplicationView : public CMyScrollView

Everything compiles fine but something is obviously wrong!

In CMyScrollView I deal with things like OnCreate, OnMouseMove, OnLButtonDown, OnSetCursor. However, these functions are never called i.e. I placed breakpoints there and they are never entered.

Can anybody tell me what I have done wrong?

As a matter of interest, some functions are called e.g. OnInitalUpdate is called.

Thanks in advance

Hi IssacJones,

maybe your view's message map is wrong - did you add these functions manaully or via ClassWizard or 'Add Event' or something?

Could you post the part of your view's file which starts with BEGIN_MESSAGE_MAP and ends with END_MESSAGE_MAP?

Yes, I'd forgotten to update the message maps in the child class so they called CMyScrollView
