Well, as I said before, it is not needed until some situation expects the right value....

One of such situations is e.g. when creating TopWindow with layout

MyWin::MyWin()
{
SetFrame(MyFrame);
CtrlLayout(*this, "");
}

Now try to make MyFrame quite thick (e.g. 50 pixels) and do not implement AddFrameSize.

Yes!

CtrlLayout calls AddFrameSize ...

template <class T>                                       // In TopWindow.h
void CtrlLayout(T& ctrl)
{
	InitLayout(ctrl, ctrl, ctrl, ctrl);
	Size sz = ctrl.AddFrameSize(T::GetLayoutSize());
	ctrl.SetMinSize(sz);
	ctrl.SetRect(sz);
}

... and AddFrameSize in turn calls FrameAddSize ...

Size Ctrl::AddFrameSize(int cx, int cy) const           // In CtrlPos.cpp
{
	Size sz = Size(cx, cy);
	for(int i = frame.GetCount() - 1; i >= 0; i--)
		frame[i].frame->FrameAddSize(sz);
	return sz;
}

Sorry for the inconvenience!
