+
+Called when an URL is being opened (either when the user clicks on a link or
+an image is loaded). The URL will be opened only if OnOpeningURL returns
+{\tt wxHTML\_OPEN}. This method is called by
+\helpref{wxHtmlParser::OpenURL}{wxhtmlparseropenurl}.

+URLs (e.g. for security reasons) or to redirect them elsewhere. Default
+behaviour is to always return {\tt wxHTML\_OPEN}.

-
-Athough it seems different the fact is that the fonts are of approximately
-same size under both platforms (due to wxMSW / wxGTK inconsistency)
+Default font sizes are defined by constants wxHTML\_FONT\_SIZE\_1,
