Re: [orca-list] What makes Orca speak dynamic page updates automatically?

[Willie Walker <William Walker Sun COM>]

Hi Nolan:

The main decision point is the handleAsLiveRegion method:

http://git.gnome.org/cgit/orca/tree/src/orca/scripts/toolkits/Gecko/script.py#n2992

There are a number of decisions being made in this method.  The best 
thing for you to do would be to analyze the event stream from your 
application and see how it may match (or not) the code.
