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

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
All windows must have a widget, with which they interact with other under-
lying GTK widgets. It is this widget, e.g. that has to be resized etc and

pointer to this widget. When the window class represents a GTK native widget,
this is (in most cases) the only GTK widget the class manages. E.g. the
wxStaticText class handles only a GtkLabel widget a pointer to which you
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

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.

- Singularily the most broken code in GTK is the code that is supposes to
+ Singularly the most broken code in GTK is the code that is supposed to
inform subwindows (child windows) about new positions. Very often, duplicate
events are sent without changes in size or position, equally often no
events are sent at all (All this is due to a bug in the GtkContainer code
which got fixed in GTK 1.2.6). For that reason, wxGTK completely ignores
GTK's own system and it simply waits for size events for toplevel windows
and then iterates down the respective size events to all window. This has
- the disadvantage, that windows might get size events before the GTK widget

added the m_nativeSizeEvents flag, which is true only for the OpenGL canvas,

V)
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
