  44     @class wxHyperlinkCtrl
  45
  46     This class shows a static text element which links to an URL.
  47     Appearance and behaviour is completely customizable.
  48
  49     In fact, when the user clicks on the hyperlink, a wxHyperlinkEvent is
  50     sent but if that event is not handled (or it's skipped; see wxEvent::Skip),
  51     then a call to wxLaunchDefaultBrowser() is done with the hyperlink's URL.
  52
  53     Note that standard wxWindow functions like wxWindow::SetBackgroundColour,
  54     wxWindow::SetFont, wxWindow::SetCursor, wxWindow::SetLabel can be used to
  55     customize appearance of the hyperlink.
  56
  57     @beginStyleTable
  58     @style{wxHL_ALIGN_LEFT}
  59            Align the text to the left.
  60     @style{wxHL_ALIGN_RIGHT}
  61            Align the text to the right.
  62     @style{wxHL_ALIGN_CENTRE}
  63            Center the text (horizontally).
  64     @style{wxHL_CONTEXTMENU}
  65            Pop up a context menu when the hyperlink is right-clicked. The
  66            context menu contains a "Copy URL" menu item which is automatically
  67            handled by the hyperlink and which just copies in the clipboard the
  68            URL (not the label) of the control.
  69     @style{wxHL_DEFAULT_STYLE}
  70            The default style for wxHyperlinkCtrl:
  71            wxBORDER_NONE|wxHL_CONTEXTMENU|wxHL_ALIGN_CENTRE.
  72     @endStyleTable
  73
  74     @beginEventEmissionTable{wxHyperlinkEvent}
  75     @event{EVT_HYPERLINK(id, func)}
  76         The hyperlink was (left) clicked. If this event is not handled in user's
  77         code (or it's skipped; see wxEvent::Skip), then a call to wxLaunchDefaultBrowser
  78         is done with the hyperlink's URL.
