[Pharo-dev] Update Nautilus layout after setting plugin's height?

Hi, I’m playing with nautilus plugins, and sometimes I want to have a lot of space for my plugin, but there are also periods of time when I want to shrink unneeded space and use it for the rest of widgets. I’ve never worked with morphs, so can someone suggest me how to do it? Should I change the height of my plugin morph with #height: and how do I update Nautilus window? (if this is possible) Uko
