  12 \section{\class{wxHyperlinkCtrl}}\label{wxhyperlinkctrl}
  13
  14 This class shows a static text element which links to an URL.
  15 Appearance and behaviour is completely customizable. In fact, when the user
  16 clicks on the hyperlink, a \helpref{wxHyperlinkEvent}{wxhyperlinkevent} is
  17 sent but if that event is not handled (or it's skipped; see
  18 \helpref{wxEvent::Skip}{wxeventskip}), then a call to
  19 \helpref{wxLaunchDefaultBrowser}{wxlaunchdefaultbrowser} is done with the
  20 hyperlink's URL.
  21
  22 Note that standard \helpref{wxWindow}{wxwindow} functions like \helpref{SetBackgroundColour}{wxwindowsetbackgroundcolour}, \helpref{SetFont}{wxwindowsetfont}, \helpref{SetCursor}{wxwindowsetcursor}, \helpref{SetLabel}{wxwindowsetlabel} can be used to customize appearance of the hyperlink.
