\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxALIGN\_LEFT}}{Align the text to the left}
\twocolitem{\windowstyle{wxALIGN\_RIGHT}}{Align the text to the right}
\twocolitem{\windowstyle{wxALIGN\_CENTRE}}{Center the text (horizontally)}
\twocolitem{\windowstyle{wxST\_NO\_AUTORESIZE}}{By default, the control will
adjust its size to exactly fit to the size of the text when 
\helpref{SetLabel}{wxstatictextsetlabel} 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 wxALIGN\_RIGHT or CENTER style because otherwise
they won't make sense any longer after a call to SetLabel)}
\twocolitem{\windowstyle{wxST\_ELLIPSIZE\_START}}{If the text width exceeds the
control width, replace the beginning of the text with an ellipsis}
\twocolitem{\windowstyle{wxST\_ELLIPSIZE\_MIDDLE}}{Same as above, but replace
the text in the middle of the control with an ellipsis}
\twocolitem{\windowstyle{wxST\_ELLIPSIZE\_END}}{Same as above, but replace the
end of the text with an ellipsis}
\twocolitem{\windowstyle{wxST\_MARKUP}}{Support markup in the label; see

\membersection{wxStaticText::wxStaticText}\label{wxstatictextconstr}

\func{}{wxStaticText}{\void}

Default constructor.

\func{}{wxStaticText}{\param{wxWindow* }{parent}, \param{wxWindowID}{ id},\rtfsp
\param{const wxString\& }{label}, \param{const wxPoint\& }{pos = wxDefaultPosition}, \param{const wxSize\& }{size = wxDefaultSize},\rtfsp
\param{long}{ style = 0}, \param{const wxString\& }{name = ``staticText"}}

Constructor, creating and showing a text control.

\wxheading{Parameters}

\docparam{parent}{Parent window. Should not be NULL.}

\docparam{id}{Control identifier. A value of -1 denotes a default value.}

\docparam{label}{Text label.}

\docparam{pos}{Window position.}

\docparam{size}{Window size.}

\docparam{style}{Window style. See \helpref{wxStaticText}{wxstatictext}.}

\docparam{name}{Window name.}

\helpref{wxStaticText::Create}{wxstatictextcreate}


\membersection{wxStaticText::Create}\label{wxstatictextcreate}

\func{bool}{Create}{\param{wxWindow* }{parent}, \param{wxWindowID}{ id},\rtfsp
\param{const wxString\& }{label}, \param{const wxPoint\& }{pos = wxDefaultPosition}, \param{const wxSize\& }{size = wxDefaultSize},\rtfsp
\param{long}{ style = 0}, \param{const wxString\& }{name = ``staticText"}}

Creation function, for two-step construction. For details see \helpref{wxStaticText::wxStaticText}{wxstatictextconstr}.


\membersection{wxStaticText::GetLabel}\label{wxstatictextgetlabel}

\constfunc{wxString}{GetLabel}{\void}

Returns the contents of the control.

Note that the returned string contains both the mnemonics (\texttt{\&} characters),
if any, and markup tags, if any.

Use \helpref{wxStaticText::GetLabelText}{wxstatictextgetlabeltext} if only the
label text is needed.


\membersection{wxStaticText::GetLabelText}\label{wxstatictextgetlabeltext}

\constfunc{wxString}{GetLabelText}{\void}

\func{static wxString}{GetLabelText}{\param{const wxString\& }{label}}

The first form returns the control's label without the mnemonics characters (if any) 
and without the markup (if the control has \texttt{wxST\_MARKUP} style).

The second (static) version returns the given \arg{label} string without the mnemonics 
characters (if any) and without the markup.


\membersection{wxStaticText::SetLabel}\label{wxstatictextsetlabel}

\func{virtual void}{SetLabel}{\param{const wxString\& }{ label}}

Sets the static text label and updates the controls size to exactly fit the
label unless the control has wxST\_NO\_AUTORESIZE flag.

This function allows to set decorated static label text on platforms which
support it (currently only GTK+ 2). For the other platforms, the markup is
ignored.

The supported tags are:

\twocolwidtha{5cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{<b>}{bold text}
\twocolitem{<big>}{bigger text}
\twocolitem{<i>}{italic text}
\twocolitem{<s>}{strike-through text}
\twocolitem{<sub>}{subscript text}
\twocolitem{<sup>}{superscript text}
\twocolitem{<small>}{smaller text}
\twocolitem{<tt>}{monospaced text}
\twocolitem{<u>}{underlined text}
\twocolitem{<span>}{generic formatter tag; see \urlref{Pango Markup}{http://developer.gnome.org/doc/API/2.0/pango/PangoMarkupFormat.html} for more information.}
\end{twocollist}

Note that the string must be well-formed (e.g. all tags must be correctly closed)
otherwise it can be not shown correctly or at all.

Also note that you need to escape the following special characters:

\twocolwidtha{5cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{\textbf{Special character}}{\textbf{Escape as}}
\twocolitem{\texttt{&}}{\texttt{&amp;} or as \texttt{&&}}
\twocolitem{\texttt{'}}{\texttt{&apos;}}
\twocolitem{\texttt{"}}{\texttt{&quot;}}
\twocolitem{\texttt{<}}{\texttt{&lt;}}
\twocolitem{\texttt{>}}{\texttt{&gt;}}
\end{twocollist}

The non-escaped ampersand \texttt{&} characters are interpreted as
mnemonics; see \helpref{wxControl::SetLabel}{wxcontrolsetlabel}.


Example:

%% TEX NOTE: in the following block we need to write the (ugly) &&amp;amp;
%%           string in order to force Tex2rtf to show the &&amp; string
\begin{verbatim}
    // this will set the wxStaticText to show the "Hello world!" string
    // with the "Hello" world in bold on platforms which support markup
    pStaticText->SetLabelWithMarkup(wxT("<b>Hello</b> world!"));

    // this will make wxStaticText show the string:
    //
    //              Specials: & ' " < >"
    //
    // with "Specials" in smaller size font if markup is supported
    pStaticText->SetLabelWithMarkup(
        wxT("<small>Specials</small>: &amp;amp; &amp;apos; &amp;quot;; &amp;lt; &amp;gt;"));
\end{verbatim}

\wxheading{Parameters}

\docparam{label}{The new label to set. It may contain newline characters and the markup tags described above.}



\membersection{wxStaticText::Wrap}\label{wxstatictextwrap}

\func{void}{Wrap}{\param{int }{width}}

This functions wraps the controls label so that each of its lines becomes at
most \arg{width} pixels wide if possible (the lines are broken at words
boundaries so it might not be the case if words are too long). If \arg{width}
is negative, no wrapping is done.
