+@section page_class_cat_basicwnd Basic Windows
+
+The following are the most important window classes
+
+@li wxWindow: base class for all windows and controls
+@li wxControl: base class (mostly) for native controls/widgets
+@li wxPanel: window which can smartly manage child windows
+@li ::wxScrolledWindow: Window with automatically managed scrollbars (see
+ wxScrolled)
+@li wxTopLevelWindow: Any top level window, dialog or frame
+
+
+
+@section page_class_cat_winlayout Window Layout
+
+There are two different systems for laying out windows (and dialogs in
+particular). One is based upon so-called sizers and it requires less typing,
+thinking and calculating and will in almost all cases produce dialogs looking
+equally well on all platforms, the other is based on so-called constraints and
+is deprecated, though still available.
+
+Related Overviews: @ref overview_sizer
+
+These are the classes relevant to sizer-based layout:

+ having the same size

+ is in, and items can span rows and/or columns.
