FWIW, the TilingWindowManager has some support for this. Not sure how it behaves in 4.x|5.x Sean did some fixes IIRC.

Re: [Pharo-users] Multi desktops inside Pharo!

by Torsten Bergmann

Hi Julien, try WorldMorph installNewWorld. which will create a new world. Open a workspace and check that it is there. WorldMorph allInstances If you click in the inspector you will see a morph representation of it - so you see which one is which. Now you have two instances of WorldMorph in your system. One is always connected to the global variable World You can switch as experiment by either: WorldMorph allInstances first install. Display restore or WorldMorph allInstances last install. Display restore The restore is necessary to update the drawing. I think you get the idea from this. As I said - the pieces are there, someone has to connect them. You dont have to thank me - it is good that you brought this into attention again and if you could devote some time in helping to bring such a nice feature also (back) to Pharo again. In case of questions do not hesitate to ask on this list or the pharo-dev list. Thanks T. > Gesendet: Montag, 24.
