Even though Eclipse is written in Java, it does not use Java widgets and thus it does not use the Java Access Bridge for accessibility. It uses SWT, which primarily uses native widgets (or at least emulates them). Unfortunately, the code editor widget doesn't seem to be or emulate a native edit widget. From what I've been able to determine, there is no external API to access it. This means that the only way to do this is via display hooks.

I thought it would be a good idea to update this ticket, just to get it back on the NVDA developer’s radar.

I have just tested with the latest nightly NVDA (Thu May 6), and latest nightly Eclipse (N20100507-2000), and the java code editor now works ... but here’s the sticky bit ... you need to restart NVDA once the java code editor has focus.

When the editor window is first opened, NVDA is unable to track the curser, however after a restart of NVDA, curser tracking works as expected, as long as you don’t alt-tab out of that window.

This is an awesome step in the right direction, and hopefully not too much hacking is required to get this to work consistently.

Thanks for updating the ticket. I forgot about this.

For the record, Eclipse 3.6pre now implements IAccessible2, but we're still experiencing some hiccups in the implementation.

Damn. Are you certain that the new nightly didn't fix the alt+tab problem? I understand why you'd have to restart at least once, but the last changes should have eliminated the brokenness on alt+tab. If they didn't, I'll need to debug it some more.

I went back and checked and you are correct, the latest Eclipse nightly (N20100507) has resolved the alt-tab issue.

#641 is needed to fix the restart requirement.

Mick, it's possible that we could get Eclipse to call !CoInitialize earlier, which would avoid the need for #641. However, if it's likely to happen again in future, we may as well try to fix it properly on our side. Thoughts?

Okay. Unless anyone has any other issues, this should be done as far as NVDA is concerned. There are still some issues with incorrect word/line offsets which breaks review among other things, but this needs to be fixed on the Eclipse side. I've already reported this to the Eclipse devs.

Now that #641 is fixed and some required fixes have been made in Eclipse, this now works in Eclipse 3.6 nightly builds.
