Description:
Developer info for the list view control

Comment 2 by nvdakor on 2014-12-09 05:28
Hi,
Hmmm, this is a bit tricky...
Technical: You need to use full installer, as MP3 Gain depends on Visual Basic 6. Probing this guy with accevent says:

• When trying to obtain the name of the selected object, it shows errors.
• For 1.34 beta, the list control fires selction and selection remove events, which may make the implementation easier.
  The biggest hurdle is getting the actual screen content - we can rely on IAccessible child iD, but that's not enough. The dev info for the list control shows nothing for name, value, description and so on.
  Thanks.

@jkinnunen: Could you provide a status update for this issue? cc @josephsl

@LeonarddeR here is the dev info. I was using MP3Gain portable:

Hi,

I and others would like to hear from the original poster before proceeding with this.

Thanks.

I have a user (from Twitter) advising that they are having the same problem, at least with the file list view, using NVDA 2019.1. I'm trying to get more information from them. Has anyone else tried out the program and replicated (or not replicated) the issue?

I've got a log now:
nvda (18).log

Forgot to add the steps to reproduce from the user:
"steps to reproduce the issue:

1. open mp3 gain.

2. press control + f to open the file picker and select some mp3 files
   to normalize.

3. tab to the list in the program, which contains the files you've
   selected.

4. move with arrows and see how NVDA just says "unknown" when it should
   read the info about the selected file, like name and actual gain."
