+See also \helpref{window styles overview}{windowstyles} and
\helpref{wxTextCtrl::wxTextCtrl}{wxtextctrlconstr}.
-\wxheading{Remarks}
+\wxheading{wxTextCtrl text format}
+
+The multiline text controls always store the text as a sequence of lines
+separated by {\tt $\backslash$n} characters, i.e. in the Unix text format even
+on non-Unix platforms. This allows the user code to ignore the differences
+between the platforms but at a price: the indices in the control such as those
+returned by \helpref{GetInsertionPoint}{wxtextctrlgetinsertionpoint} or
+\helpref{GetSelection}{wxtextctrlgetselection} can {\bf not} be used as
+indices into the string returned by \helpref{GetValue}{wxtextctrlgetvalue} as
+they're going to be slightly off for platforms using
+{\tt $\backslash$r$\backslash$n} as separator (as Windows does), for example.
+
+Instead, if you need to obtain a substring between the $2$ indices obtained
+from the control with the help of the functions mentioned above, you should
+use \helpref{GetRange}{wxtextctrlgetrange}. And the indices themselves can
+only be passed to other methods, for example
+\helpref{SetInsertionPoint}{wxtextctrlsetinsertionpoint} or
+\helpref{SetSelection}{wxtextctrlsetselection}.
+
+To summarize: never use the indices returned by (multiline) wxTextCtrl as
+indices into the string it contains, but only as arguments to be passed back
+to the other wxTextCtrl methods.
+
+\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}
+}%

+If your compiler does not support derivation from {\bf streambuf} and gives a
+compile error, define the symbol {\bf NO\_TEXT\_WINDOW\_STREAM} in the
wxTextCtrl header file.
+Note that independently of this setting you can always use wxTextCtrl itself
+in a stream-like manner:
+
+{\small%
+\begin{verbatim}
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ *control << 123.456 << " some text\n";
+\end{verbatim}
+}%
+
+always works. However the possibility to create an ostream associated with
+wxTextCtrl may be useful if you need to redirect the output of a function
+taking an ostream as parameter to a text control.
+
+Another commonly requested need is to redirect {\bf std::cout} to the text
+control. This could be done in the following way:
+
+{\small%
+\begin{verbatim}
+ #include <iostream>
+
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ std::streambuf *sbOld = std::cout.rdbuf();
+ std::cout.rdbuf(*control);
+
+ // use cout as usual, the output appears in the text control
+ ...
+
+ std::cout.rdbuf(sbOld);
+\end{verbatim}
+}%
+
+But wxWindows provides a convenient class to make it even simpler so instead
+you may just do
+
+{\small%
+\begin{verbatim}
+ #include <iostream>
+
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ wxStreamToTextRedirector redirect(control);
+
+ // all output to cout goes into the text control until the exit from current
+ // scope
+\end{verbatim}
+}%
+
+See \helpref{wxStreamToTextRedirector}{wxstreamtotextredirector} for more
+details.

+\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

\membersection{wxTextCtrl::SetInsertionPoint}\label{wxtextctrlsetinsertionpoint}
Sets the insertion point at the end of the text control. This is equivalent
to \helpref{SetInsertionPoint}{wxtextctrlsetinsertionpoint}(\helpref{GetLastPosition}{wxtextctrlgetlastposition}()).
+\membersection{wxTextCtrl::SetMaxLength}\label{wxtextctrlsetmaxlength}
+
+\func{virtual void}{SetMaxLength}{\param{unsigned long }{len}}
+
+This function sets the maximum number of characters the user can enter into the
+control. In other words, it allows to limit the text value length to {\it len}
+not counting the terminating {\tt NUL} character.
+
+If {\it len} is $0$, the previously set max length limit, if any, is discarded
+and the user may enter as much text as the underlying native text control
+widget supports (typically at least 32Kb).
+
+If the user tries to enter more characters into the text control when it
+already is filled up to the maximal length, a
+{\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.
+
+Note that this function may only be used with single line text controls.
+
+\wxheading{Compatibility}
+
+Only implemented in wxMSW/wxGTK starting with wxWindows 2.3.2.

+\membersection{wxTextCtrl::SetStyle}\label{wxtextctrlsetstyle}
+
+\func{bool}{SetStyle}{\param{long }{start}, \param{long }{end}, \param{const wxTextAttr\& }{style}}
+
+Changes the style of the given range. If any attribute within {\it style} is
+not set, the correspondign attribute from \helpref{GetDefaultStyle()}{wxtextctrlgetdefaultstyle} is used.
+
+\wxheading{Parameters}
+
+\docparam{start}{The start of the range to change.}

+\docparam{end}{The end of the range to change.}
+
+\docparam{style}{The new style for the range.}
