Is there a mechanism in place to know when a Web AppBuilder app/map has been fully initialized and the entire DOM built and visible? We need to know when the app is ready for use (specifically, when the Header Widget is visible) so we can perform some minor DOM manipulation. We could use javascript's setTimeout to periodically check for the existince of the DOM elements in which we're interested, but perhaps there's a cleaner way to do this using WAB or dojo events or callbacks?
Thanks,
