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.

+ Normally one might expect, that one wxWidgets window would always correspond
to one GTK widget. Under GTK, there is no such allround 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
still have the possibility to draw something in the client area.
It was therefore required to write a special purpose GTK widget, that would

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
