you cannot understand wxGTK without knowing a little about the GTK, but
some more information about what the wxWindow, which is the base class
for all other window classes, does seems required as well.

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
still have the possibility to draw something in the client area.
It was therefore required to write a special purpose GTK widget, that would

lying GTK widgets. It is this widget, e.g. that has to be resized etc and

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.

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

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
- the window. In wxWindows, the scrollbar will only emit an event, send this
+ 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

so that the two coordinates systems have to be kept in synch. This is done

- 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
+ the disadvantage that windows might get size events before the GTK widget
actually has the reported size. This doesn't normally pose any problem, but

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

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
