-\constfunc{wxCoord}{OnGetLineHeight}{\param{size\_t }{n}}
+\constfunc{virtual wxCoord}{OnGetLineHeight}{\param{size\_t }{n}}
This protected virtual function must be overridden in the derived class and it
should return the height of the given line in pixels.

-\constfunc{void}{OnGetLinesHint}{\param{size\_t }{lineMin}, \param{size\_t }{lineMax}}
+\constfunc{virtual void}{OnGetLinesHint}{\param{size\_t }{lineMin}, \param{size\_t }{lineMax}}
This function doesn't have to be overridden but it may be useful to do
it if calculating the lines heights is a relatively expensive operation
