Re: [orca-list] SWT (Standard Widget Toolkit) for Java platform accessibility

[Michael Whapples <mwhapples aim com>]

I am not sure how to know for certain, but you can check the following.
If the application is accessible via ATK (not requiring the
gnome-java-access-bridge) then it could be a SWT app. Java swing relies
on the java access bridge, and I think you can tell this by using the
orca script information key. I don't know what orca reports about the
window if it is using SWT, anyone know?
