I was wondering what the proper way is to specify location of items inside of say a toolbar widget. Let's keep it simple and say I want to place Button X on the left side, Button Y on the right side, and Span Z in the middle. I've tried using css and it simply doesn't work, as when you mouse-over the buttons any class that was added gets removed permanently. This would be a programmatic method, BTW. Do I have to use a layout to achieve this?
