[Pharo-project] Open window out of my pharo environment

by Tristan Bourgois

Hi! all my question is in the object ^^ Does exist the possibility to open a window out of my pharo environment? (Or someone know the way to do that?) I'm working on a graphic framework and at my work they need a multi screen support. It's needed to validate Pharo as the smalltalk they will use! Thanks! Tristan

Re: [Pharo-project] Is renamePackage in Nautilus correct ?

Le 11/04/2013 17:41, Benjamin a Ã©crit : > Most probably yes :) Ok then, I'll do something like : not allow rename on a MC Package, allow rename on a RPackage.

It links directly to RPackageOrganizer without dependencies on the refactoring engine, so it's probably you :) There is a method which may be of interest to note, which is isValidPackageName:; why not moving it to RPackage so that we keep a bit of self-documenting validation there?
