virtual void FocusOnChild(CGXChild* pChild);?
pChild
Pointer to the CGXChild object.
Sets the focus to a child. LButtonDown, MButtonDown and RButtonDown call this method when a CGXChild was hit.
Please do not misinterpret the term ‘focus’. CGXChild objects are not derived from CWnd and thus cannot receive keyboard input. In the context of CGXChild, the term ‘focus’ means that CGXControl will send subsequent mouse messages (MouseMove, LButtonUp, ...) and KeyPressed calls to this CGXChild.
