Enlarging window with gtk_scrolled_window

[Andreas Tille <tille physik uni-halle de>]

Hello

my little application contains a vbox.  In this vbox I put
a scrolled window and a hbox containing a button.  If I
enlarge the window, both the scrolled window and the button
become larger.

What do I have to do to avoid enlarging the hbox with the
button, because I intend to get the behaviour that only the
scrolled window changes it's size?

Kind regards

           Andreas.
