Scrolling GtkTextView dialog

[Dave Bentham <dave bentham ntlworld com>]

Hi,

Can someone please help a newbie?

I've developed a GtkDialog with a GtkTextView widget, which basically
outputs lines of text during a process started in the main GTK
application (GTK+ 2.0.9).

At the moment, when the default size is exceeded by the content, the
dialog magically grows to accomodate it; and it cannot be
manually reduced in size beyond the displayed text.

Can such a dialog be forced to use scroll bars over a certain size of
dialog?

Cheers

Dave.
