Re: When safe at startup to get element positions/dimensions?

Works ... thanks!    As to HeaderPanel... my HTML layout is working OK. I might have saved effort   by starting with a more widget-oriented layout, but those costs are now sunk.

The code inside the command is delayed slightly, so it will be executed AFTER all your other JS code is done (so its kind of async) and the browser had some time to do its layout computations.

GWT's HeaderPanel widget (header + center + footer) does the same to recalculate the height of the center area. Maybe you can actually use it?
