Never tried this, seems to me an unconfortable behaviour, having the main 
window shrink and expand...

Maybe you can try to reimplement one of the

resizeColumnsToContents
columnResized

methods. One of them should be called whenever the size hint of the content 
changes. You can get the new size and set the size hint for the parent (main 
window). Makes sense?
