Greetings:

I am trying to make a custom combo box that is like the TColorBox component
but has additional support for colors with alpha.  The problem I'm having is
that I can't seem to override the DrawItem method.  In my derived class, the
function declaration is the same as the one in its parent's class,
TCustomComboBox.  The declaration looks like this:

virtual void __fastcall DrawItem(int Index, const Types::TRect &Rect,
Windows::TOwnerDrawState State);

In my class, I have it declared exactly as shown above, but it never gets
called from my control.  Instead, it calls the parent class's DrawItem
method.  Any ideas what I am doing wrong?
