  45     This class shows a static text element which links to an URL.
  46     Appearance and behaviour is completely customizable. In fact, when the user
  47     clicks on the hyperlink, a wxHyperlinkEvent is
  48     sent but if that event is not handled (or it's skipped; see
  49     wxEvent::Skip), then a call to
  50     wxLaunchDefaultBrowser() is done with the
  51     hyperlink's URL.
  52
  53     Note that standard wxWindow functions like wxWindow::SetBackgroundColour,
  54     wxWindow::SetFont, wxWindow::SetCursor, wxWindow::SetLabel can be used to customize appearance of the hyperlink.
  55
  56     @beginStyleTable
  57     @style{wxHL_ALIGN_LEFT}:
  58            Align the text to the left.
  59     @style{wxHL_ALIGN_RIGHT}:
  60            Align the text to the right.
  61     @style{wxHL_ALIGN_CENTRE}:
  62            Center the text (horizontally).
  63     @style{wxHL_CONTEXTMENU}:
  64            Pop up a context menu when the hyperlink is right-clicked. The
  65            context menu contains a "Copy URL" menu item which is automatically
  66            handled by the hyperlink and which just copies in the clipboard the
  67            URL (not the label) of the control.
  68     @style{wxHL_DEFAULT_STYLE}:
  69            The default style for wxHyperlinkCtrl:
