There should not be any big problem... 1.1.1 just had some bug fixes (mostly related to be able to use Cog). No code removed, nothing deprecated in addition. You can see all changes here: http://code.google.com/p/pharo/issues/list?can=1&q=milestone%3D1.1.1 Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

thanks a lot for sharing that with us. Should I deduce that is it MIT-license?

Change your alias. It is childish to ask for help in programming if you do not want to program. Use any funny alias but not that one!

How to make a Morph that gets to handle all arrow-key-events?
by reluctant Nov. 21, 2010

Nov. 21, 2010

hi, for a game i want one Morph to get all the arrow-key-events, whether it has the focus or not. what is the best way to make this happen? is it a good idea anyway? One Morph-Object can be moved around the screen using arrow keys. i thought it would be the best if it would listen to the arrow-key-events itself? thank you very much for help. -- View this message in context: http://forum.world.st/How-to-make-a-Morph-that-gets-to-handle-all-arrow-key… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
