/**
    @class wxStaticText

    A static text control displays one or more lines of read-only text.
    wxStaticText supports the three classic text alignments, label
    ellipsization i.e. replacing parts of the text with the ellipsis ("...") if
    the label doesn't fit into the provided space and also formatting markup
    with wxControl::SetLabelMarkup().

    @beginStyleTable
    @style{wxALIGN_LEFT}
           Align the text to the left.
    @style{wxALIGN_RIGHT}
           Align the text to the right.
    @style{wxALIGN_CENTRE_HORIZONTAL}
           Center the text (horizontally).
    @style{wxST_NO_AUTORESIZE}
           By default, the control will adjust its size to exactly fit to the
           size of the text when SetLabel() is called. If this style flag is
           given, the control will not change its size (this style is
           especially useful with controls which also have the @c wxALIGN_RIGHT or
           the @c wxALIGN_CENTRE_HORIZONTAL style because otherwise they won't make sense any
           longer after a call to SetLabel()).
    @style{wxST_ELLIPSIZE_START}
           If the labeltext width exceeds the control width, replace the beginning
           of the label with an ellipsis; uses wxControl::Ellipsize.
    @style{wxST_ELLIPSIZE_MIDDLE}
           If the label text width exceeds the control width, replace the middle
           of the label with an ellipsis; uses wxControl::Ellipsize.
    @style{wxST_ELLIPSIZE_END}
           If the label text width exceeds the control width, replace the end
           of the label with an ellipsis; uses wxControl::Ellipsize.
