scrolled window adjustment 'changed' signal question

[James Morris <jwm art net gmail com>]

Hi,

As from my previous email, I require the dimensions of the scrolled
window. I decided to detect when they change (due to the top level
window being resized) by using the 'changed' signal emitted by the
hadjustment and vadjustment respectively.

So I create two user functions one for when window width is changed,
and the other for when window height is changed. Using
g_signal_connect I connect the scrolled window's hadjustment and
vadjustments respectively (to the user functions).

The behaviour seems a little odd though: if I only change width OR
height (NOT both) then BOTH adjustments emit the 'changed' signal.

Is this supposed to happen like this?

(gtk version 2.20)

Thanks,
James.
