Thank you for the response.
Yes, I should have stated I found the thread you linked and still had difficulties. While the StateChanged event did fire when I added the toolwindow to the layoutmanager, it had no effect on the width.
I was able to get it to work only when I spun off the Statechanged event on a seperate thread.
I am not sure this is the most elegant answer, but it works for now.
