  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 clicks on the hyperlink, a \helpref{wxHyperlinkEvent}{wxhyperlinkctrlevent} is sent but if that event is not handled (or it's skipped; see \helpref{wxEvent::Skip}{wxeventskip}), then a call to \helpref{wxLaunchDefaultBrowser}{wxlaunchdefaultbrowser} is done with the hyperlink's URL.
  16
  17 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.
