[Pharo-project] TilingWM - layout policies

Thanks to Stefan, Serge, Patrick and Estelle now you can choose a Layout Strategy in settings. Actually there's Horizontal (default) and Vertical (last used windows fills all remaining space) strategies. To add your own just subclass TWMLayoutStrategy and implement #tileWindows: Cheers, Laurent Laffont - @lolgzs <http://twitter.com/#!/lolgzs> Pharo Smalltalk Screencasts: http://www.pharocasts.com/ Blog: http://magaloma.blogspot.com/ Developer group: http://cara74.seasidehosting.st
