    If the m_wxwindow field is set, then all input to this widget is inter-
    cepted and sent to the wxWindows class. If not, all input to the widget
    that gets pointed to by m_widget gets intercepted and sent to the class.

    II)
-   
+
    The design of scrolling in wxWindows is markedly different from that offered
    by the GTK itself and therefore we cannot simply take it as it is. In GTK,
    clicking on a scrollbar belonging to scrolled window will inevitably move
    memorizes how much it has been scrolled but that wxWindows 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.
-   
-   III) 
-   
+
+   III)
+
    Singularily the most broken code in GTK is the code that is supposes to
    inform subwindows (child windows) about new positions. Very often, duplicate
    events are sent without changes in size or position, equally often no
    GTK).
 
    IV)
-   
+
    If someone at some point of time feels the immense desire to have a look at,
    change or attempt to optimse the Refresh() logic, this person will need an
    intimate understanding of what a "draw" and what an "expose" events are and
    what there are used for, in particular when used in connection with GTK's
    own windowless widgets. Beware.
-   
+
    V)
-   
+
    Cursors, too, have been a constant source of pleasure. The main difficulty
    is that a GdkWindow inherits a cursor if the programmer sets a new cursor
    for the parent. To prevent this from doing too much harm, I use idle time
    and ending with the youngest generation (speaking of parent and child windows).
    Also don't forget that cursors (like much else) are connected to GdkWindows,
    not GtkWidgets and that the "window" field of a GtkWidget might very well
-   point to the GdkWindow of the parent widget (-> "window less widget") and 
+   point to the GdkWindow of the parent widget (-> "window less widget") and
    that the two obviously have very different meanings.
