/**
    @class wxHyperlinkCtrl

    This class shows a static text element which links to an URL.
    Appearance and behaviour is completely customizable. In fact, when the user
    clicks on the hyperlink, a wxHyperlinkEvent is
    sent but if that event is not handled (or it's skipped; see
    wxEvent::Skip), then a call to
    wxLaunchDefaultBrowser() is done with the
    hyperlink's URL.

    Note that standard wxWindow functions like wxWindow::SetBackgroundColour,
    wxWindow::SetFont, wxWindow::SetCursor, wxWindow::SetLabel can be used to customize appearance of the hyperlink.

    @beginStyleTable
    @style{wxHL_ALIGN_LEFT}
           Align the text to the left.
    @style{wxHL_ALIGN_RIGHT}
           Align the text to the right.
    @style{wxHL_ALIGN_CENTRE}
           Center the text (horizontally).
    @style{wxHL_CONTEXTMENU}
           Pop up a context menu when the hyperlink is right-clicked. The
           context menu contains a "Copy URL" menu item which is automatically
           handled by the hyperlink and which just copies in the clipboard the
           URL (not the label) of the control.
    @style{wxHL_DEFAULT_STYLE}
           The default style for wxHyperlinkCtrl:
           wxBORDER_NONE|wxHL_CONTEXTMENU|wxHL_ALIGN_CENTRE.
