 wxWindow (and therefore all window classes) are derived from
 this class.
 
+When events are received, wxEvtHandler invokes the method listed in the
+event table using itself as the object.  When using multiple inheritance
+it is imperative that the wxEvtHandler(-derived) class be the first
+class inherited such that the "this" pointer for the overall object
+will be identical to the "this" pointer for the wxEvtHandler portion.
