\section{\class{wxWindow}}\label{wxwindow}
-wxWindow is the base class for all windows. Any children of the window will be deleted
-automatically by the destructor before the window itself is deleted.
-
-%Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
-%help text. These must not be called by a user program and are documented only for illustration.
-%On several platforms, only a few of these handlers are actually written (they are not always
-%needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
-%the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
-%platform can implement its native behaviour or just ignore the event if nothing needs to be
-%done.
+wxWindow is the base class for all windows and represents any visible objecto n
+screen. All controls, top level windows and so on are windows. Sizers and
+device contexts are not, however, as they don't appear on screen themselves.
+
+Please note that all children of the window will be deleted automatically by
+the destructor before the window itself is deleted which means that you don't
+have to worry about deleting them manually. Please see the \helpref{window
+deletion overview}{windowdeletionoverview} for more information.
+
+Also note that in this, and many others, wxWindows classes some
+\texttt{GetXXX()} methods may be overloaded (as, for example,
+\helpref{GetSize}{wxwindowgetsize} or
+\helpref{GetClientSize}{wxwindowgetclientsize}). In this case, the overloads
+are non-virtual because having multiple virtual functions with the same name
+results in a virtual function name hiding at the derived class level (in
+English, this means that the derived class has to override all overloaded
+variants if it overrides any of them). To allow overriding them in the derived
+class, wxWindows uses a unique protected virtual \texttt{DoGetXXX()} method
+and all \texttt{GetXXX()} ones are forwarded to it, so overriding the former
+changes the behaviour of the latter.

Adds a child window. This is called automatically by window creation
functions so should not be required by the application programmer.

\wxheading{Remarks}
Dialog units are used for maintaining a dialog's proportions even if the font changes.
-Dialogs created using Dialog Editor optionally use dialog units.
You can also use these functions programmatically. A convenience macro is defined:
