Normally one might expect, that one wxWidgets window would always correspond

+ to one GTK widget. Under GTK, there is no such all-round widget that has all
the functionality. Moreover, the GTK defines a client area as a different
widget from the actual widget you are handling. Last but not least some
special classes (e.g. wxFrame) handle different categories of widgets and
can find in m_widget (defined in wxWindow)
When the class has a client area for drawing into and for containing children
- it has to handle the client area widget (of the type GtkPizza, defined in
- win_gtk.c), but there could be any number of widgets, handled by a class
+ it has to handle the client area widget (of the type wxPizza, defined in

The common rule for all windows is only, that the widget that interacts with
the rest of GTK must be referenced in m_widget and all other widgets must be
children of this widget on the GTK level. The top-most widget, which also
represents the client area, must be in the m_wxwindow field and must be of
- the type GtkPizza.
+ the type wxPizza.
As I said, the window classes that display a GTK native widget only have
one widget, so in the case of e.g. the wxButton class m_widget holds a
pointer to a GtkButton widget. But windows with client areas (for drawing
and children) have a m_widget field that is a pointer to a GtkScrolled-
- Window and a m_wxwindow field that is pointer to a GtkPizza and this

one is (in the GTK sense) a child of the GtkScrolledWindow.
If the m_wxwindow field is set, then all input to this widget is inter-
clicking on a scrollbar belonging to scrolled window will inevitably move
the window. In wxWidgets, the scrollbar will only emit an event, send this
to (normally) a wxScrolledWindow and that class will call ScrollWindow()
- which actually moves the window and its subchildren. Note that GtkPizza
+ which actually moves the window and its sub-windows. Note that wxPizza
memorizes how much it has been scrolled but that wxWidgets forgets this
so that the two coordinates systems have to be kept in synch. This is done
- in various places using the pizza->xoffset and pizza->yoffset values.
