+Note that independently of this setting you can always use wxTextCtrl itself
+in a stream-like manner:

+  wxTextCtrl *control = new wxTextCtrl(...);
+
+  *control << 123.456 << " some text\n";

+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}
