+If your compiler does not support derivation from {\bf streambuf} and gives a

+
+Note that independently of this setting you can always use wxTextCtrl itself

+  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(...);

-Note that any use of C++ iostreams (including this one) deprecated and might get completely removed
-in the future.
+But wxWindows provides a convenient class to make it even simpler so instead
+you may just do
+
+{\small%
