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.

Latest windows CogVM + Pharo 1.1 - fail to load system fonts
by Stanislav Paskalev Nov. 18, 2010

Nov. 18, 2010

Hi, No errors are reported or anything, it's just that the fonts list is not populated with CogVM. Using the same image and the pharo 4.0.2 win32 vm - it's filled ok. Where do we report bugs against CogVM ? Best regards, Stanislav Paskalev

Solution to Can't Quit Pharo Found
by Scott Clausen Nov. 17, 2010

Nov. 17, 2010

Luc and all, I've found that I can quit Pharo via the popup menu selection. I just can't quit it from the drop down menu In the menubar. Now I can go ahead and work through the docs. Thanks to all for listening. Scott A man who limits his interests limits his life. -- Vincent Price

"Hi Scott, Which virtual machine do you use and which image? and which versions? Luc" Luc, I'm using Pharo-1.1-OneClick on OSX 10.6.5. It appeared to be the easiest path to get started. Everything seems to work fine otherwise. Scott A man who limits his interests limits his life. -- Vincent Price
