how to hook up components to share state

[Craig Hamilton <CH...@celeres.ca>]

I have a QueryComponent, which is responsible for performing queries and
allowing the user to select the result they with to work with.  Also on
the page, I have a tab control, which has components which can perform
operations on the selected object from the QueryComponent.  How should I
hook it up such that the object which is selected within the
QueryComponent is known to the component within the selected tab? 

 

I have figured out how to have a listener on the page which gets
notified when a new query is performed...but I haven't figured out how
to get the selected object back to the page, and then on to the other
components.

 

Any help much appreciated.

 

Thanks,

 

Craig

How does the user select an object? Possible to get the selected
index using javascript?
