Its implemented that way for performance: Inside the current event loop you can call as many layout methods as you like and the layout is done all at once in a finally command and not after every layout method call. If you need the changes to take effect immediately you have to call LayoutPanel.forceLayout().
Also sometimes you just need a Scheduler.get().scheduleDeferred() command to read changed width/height values because the browser needs some time to re-render your widget. Only when its re-rendered the browser can give you the new, correct width/height values. So if you ever see strange width/height values, try a scheduleDeferred.
