How to communicate between SFV widgets?

PeterHanmore — Tue, 15 Jun 2010 18:52:13 GMT

I'm trying to implement an enhancement to the identify tool which would update the identifyParams.layerIDs to the ID of the currently selected layer in the TOC. I haven't been able to figure out a simple way of determining the state of the TOC (from LiveMapsWidget.mxml) in the IdentifyWidget.mxml. Is there a way to get a reference to the toc object? Has anyone else already done an updated Identify widget that accomplishes this task (I have looked but haven't seen any)? Is there any general documentation available on how you can communicate / query between objects in different widgets?

Thanks for any pointers in the right direction.

Thanks very much ... it worked great! Gave me some insight into how the whole communication thing happens too. Ended up extending it a bit more to zoom to feature extent instead of the default of just zooming to the point clicked on.

Cheers,
Peter.
