+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.

\docparam{autoLayout}{Set this to TRUE if you wish the Layout function to be called

-
-Note that this function is actually disabled for wxWindow and only indirectly
-takes affect for children of wxDialog, wxFrame, wxNotebook and wxSplitterWindow.

\helpref{wxWindow::SetConstraints}{wxwindowsetconstraints}
may wish to call \helpref{wxWindow::Clear}{wxwindowclear} or \helpref{wxWindow::Refresh}{wxwindowrefresh} after
calling this function.
-Note that when using this functions under GTK, you will disable the so called "themes",
-i.e. the user chosen apperance of windows and controls, including the themes of
-their parent windows.
+Use this function with care under GTK as the new appearance of the window might
+not look equally well when used with "Themes", i.e GTK's ability to change its
+look as the user wishes with run-time loadable modules.

\func{virtual void}{SetCursor}{\param{const wxCursor\&}{cursor}}
-Sets the window's cursor. Notice that setting the cursor for this window does
-not set it for its children so you'll need to explicitly call SetCursor() for
-them too if you need it.

+Sets the window's cursor. Notice that the window cursor also sets it for the
