In the last paragraph above, do you really mean the size ? The adjustments do
not affect the size of your widget, they just affect which part of the widget
is currently visible.

In the sources of gtkscrolledwindow.c, you should especially look at the
gtk_scrolled_window_size_request and gtk_scrolled_window_size_allocate
routines, since these are the ones that handle the resizing of the widget.
