Jeff, since you running linux you can look at what we have done with Ronie not long ago. Basically we changed VM and removed all window/event management code and instead do everything at image side. I think it would be good if you can try and add multi-touch events support to the code.
If you wanna try, you need to build new VM first, and follow this: https://pharo.fogbugz.com/f/cases/12743/OSWindow-integration Then you can look at OSWindow package (its X11 part) and see what is needed to support multi-touch events. You should build VM from sources taken from here: https://github.com/ronsaldo/pharo-vm On 11 March 2014 11:37, J.F.
