     Helper class for managing choices of wxPropertyGrid properties.
     Each entry can have label, value, bitmap, text colour, and background
     colour.
+ 
+    wxPGChoices uses reference counting, similar to other wxWidgets classes.
+    This means that assignment operator and copy constructor only copy the
+    reference and not the actual data. Use Copy() member function to create a
+    real copy.
 
     @remarks If you do not specify value for entry, index is used.
