+It should be rarely, if ever, used because 
+\helpref{SetSelectionBackground}{wxvlistboxsetselectionbackground} allows to

+
+This virtual function may be overridden to customize the appearance of the
+selected cells. It is used to determine how the colour {\it colFg} is going to
+look inside selection. By default all original colours are completely ignored
+and the standard, system-dependent, selection colour is used but the program
+may wish to override this to achieve some custom appearance.
