A text control allows text to be displayed and edited. It may be

+See also \helpref{window styles overview}{windowstyles} and
\helpref{wxTextCtrl::wxTextCtrl}{wxtextctrlconstr}.
+\wxheading{wxTextCtrl styles}
+
+Multi-line text controls support the styles, i.e. provide a possibility to set
+colours and font for individual characters in it (note that under Windows {\tt
+wxTE\_RICH} style is required for style support). To use the styles you can
+either call \helpref{SetDefaultStyle}{wxtextctrlsetdefaultstyle} before
+inserting the text or call \helpref{SetStyle}{wxtextctrlsetstyle} later to
+change the style of the text already in the control (the first solution is
+much more efficient).
+
+In either case, if the style doesn't specify some of the attributes (for
+example you only want to set the text colour but without changing the font nor
+the text background), the values of the default style will be used for them.
+If there is no default style, the attributes of the text control itself are
+used.
+
+So the following code correctly describes what it does: the second call
+to \helpref{SetDefaultStyle}{wxtextctrlsetdefaultstyle} doesn't change the
+text foreground colour (which stays red) while the last one doesn't change the
+background colour (which stays grey):
+
+{\small%
+\begin{verbatim}
+ text->SetDefaultStyle(wxTextAttr(*wxRED));
+ text->AppendText("Red text\n");
+ text->SetDefaultStyle(wxTextAttr(wxNullColour, *wxLIGHT_GREY));
+ text->AppendText("Red on grey text\n");
+ text->SetDefaultStyle(wxTextAttr(*wxBLUE);
+ text->AppendText("Blue on grey text\n");
+\end{verbatim}

in the text control (Win32 only)}

Resets the internal `modified' flag as if the current edits had been saved.
+\membersection{wxTextCtrl::GetDefaultStyle}\label{wxtextctrlgetdefaultstyle}
+
+\constfunc{const wxTextAttr\& }{GetDefaultStyle}{\void}
+
+Returns the style currently used for the new text.

+
+\helpref{SetDefaultStyle}{wxtextctrlsetdefaultstyle}
+
\membersection{wxTextCtrl::GetInsertionPoint}\label{wxtextctrlgetinsertionpoint}
\constfunc{virtual long}{GetInsertionPoint}{\void}
Gets the current selection span. If the returned values are equal, there was
no selection.
+Please note that the indices returned may be used with the other wxTextctrl
+methods but don't necessarily represent the correct indices into the string
+returned by \helpref{GetValue()}{wxtextctrlgetvalue} for multiline controls
+under Windows (at least,) you should use
+\helpref{GetStringSelection()}{wxtextctrlgetstringselection} to get the selected
+text.
+
\wxheading{Parameters}
\docparam{from}{The returned first position.}
\perlnote{In wxPerl this method takes no parameter and returns a
2-element list {\tt ( from, to )}.}
+\membersection{wxTextCtrl::GetStringSelection}\label{wxtextctrlgetstringselection}
+
+\func{virtual wxString}{GetStringSelection}{\void}
+
+Gets the text currently selected in the control. If there is no selection, the
+returned string is empty.
+
\membersection{wxTextCtrl::GetValue}\label{wxtextctrlgetvalue}
\constfunc{wxString}{GetValue}{\void}
TRUE if the operation was successful, FALSE otherwise.
+\membersection{wxTextCtrl::SetDefaultStyle}\label{wxtextctrlsetdefaultstyle}
+
+\func{bool}{SetDefaultStyle}{\param{const wxTextAttr\& }{style}}
+
+Changes the default style to use for the new text which is going to be added
+to the control using \helpref{WriteText}{wxtextctrlwritetext} or\rtfsp
+\helpref{AppendText}{wxtextctrlappendtext}.
+
+If either of the font, foreground, or background colour is not set in\rtfsp
+{\it style}, the values of the previous default style are used for them. If
+the previous default style didn't set them neither, the global font or colours
+of the text control itself are used as fall back.
+
+However if the {\it style} parameter is the default wxTextAttr, then the
+default style is just reset (instead of being combined with the new style which
+wouldn't change it at all).
+
+\wxheading{Parameters}
+
+\docparam{style}{The style for the new text.}
+
+\wxheading{Return value}
+
+{\tt TRUE} on success, {\tt FALSE} if an error occured - may also mean that
+the styles are not supported under this platform.

{\tt wxEVT\_COMMAND\_TEXT\_MAXLEN} event is sent to notify the program about it
(giving it the possibility to show an explanatory message, for example) and the
extra input is discarded.

+\membersection{wxTextCtrl::SetStyle}\label{wxtextctrlsetstyle}
+
+\func{bool}{SetStyle}{\param{long }{start}, \param{long }{end}, \param{const wxTextAttr\& }{style}}
+
+Changes the style of the selection. If either of the font, foreground, or
+background colour is not set in {\it style}, the values of\rtfsp
+\helpref{GetDefaultStyle()}{wxtextctrlgetdefaultstyle} are used.
+
+\wxheading{Parameters}
+
+\docparam{start}{The start of selection to change.}
+
+\docparam{end}{The end of selection to change.}
+
+\docparam{style}{The new style for the selection.}

+\wxheading{Return value}
