Add a "categoryItemIsExpanded"

[GoogleCodeExporter]

Is it possible to add a way to know if a SourceListCategory is expanded?

SourceList has the method "setExpanded(SourceListCategory, boolean)" but 
there's not a method 
"isExpanded(SourceListCategory)" or similar. I think it would be useful. Thanks!

Hi! I try to explain.

When the user closes my application (jCodeCollector, http://tinyurl.com/lmtz72 
) I'd want to save the "expanded 
state" of all SourceListCategories. In this way when he'll relaunch the 
application, the "expanded state" of all 
categories will be restored.

So you don't need to really track it, you just need to be able to get the 
expanded state of everything at once?

Exactly!

I plan to add a method called getExpandedState, which will return a list of 
expanded states in a depth first 
traversal of the nodes. I'll also add a method that lets you supply this list 
of expanded states in order to install 
them on startup.

Does this sound reasonable?

Yes, it does!
Thank you so much :)
