This week I've tried to make Pharo a little better on window management. This video shows the progress (thanks Gastón and Patrick for help and ideas).
Next step: KeyMapping integration + history à la Emacs winner-mode.
Sorry for my soooooooo awful english (tired ....).
Update 05/31/2011: you can load last version with colored theme with:
Gofer it squeaksource: 'TilingWindowManager'; package: 'TWM'; load. (Smalltalk at: #StandardUITheme) beCurrent. (Smalltalk at: #TWMBar) showTWMBar:true.
Tested on PharoCore 1.2 and Pharo 1.3.
Now this has support for world snapshot, that means you can arrange the windows and take a snapshot of the layout. Then you can restore these layouts later. (icons camera, <, > and trash). I'm not entirely satisfied with this, thanks for feedback.
In Pharo 1.3 there's initial integration with KeyMapping. To load:
Gofer it squeaksource: 'ShortWays'; package: 'ConfigurationOfKeymapping'; load. (Smalltalk at: #ConfigurationOfKeymapping project version: '1.7') load.
Then in settings browser > Keymappings > Tiling Window Managers you have all actions of the dock mapped.
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:
To load TWM:
Gofer it squeaksource: 'TilingWindowManager'; package: 'TWM'; load.
I also think the UI theme Patrick has cleaned fits better with TilingWM:
Gofer it squeaksource: 'PBASandbox'; package: 'PBSandbox'; load. StandardUITheme beCurrent.
