-\wxheading{Remarks}
+\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).

 
 

-This class multiply-inherits from {\bf streambuf} where compilers allow, allowing code such as the following:
+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);

+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}

+details.

+This function sets the maximum number of characters the user can enter into the

+If {\it len} is $0$, the previously set max length limi, if any, is discarded

+If the user tries to enter more characters into the text control when it
