+   win_gtk.cpp), but there could be any number of widgets, handled by a class.
    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
+   Window and a m_wxwindow field that is pointer to a wxPizza 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 sub-windows. 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.

-    // from the current widget or its child widgets.  However, only the widget
-    // with the INPUT FOCUS can generate the INITIAL key_press event.  That is,

-    // originated from its child widgets and shouldn't be passed to IM context.
-    // In fact, what a GTK+ IM should do is filtering keyEvents and convert them
-    // into text input ONLY WHEN THE WIDGET HAS INPUT FOCUS.  Besides, when current
-    // widgets has both IM context and input focus, the event should be filtered
-    // by gtk_im_context_filter_keypress().
