Error after changing input language with Notepad++ #7931

Open feerrenrut opened 6 years ago

feerrenrut commented 6 years ago

While reproducing #7924 I found the following

Steps to reproduce:

  1. Make sure Automatic Language Switching and Automatic Dialect Switching are enabled in the Voice Settings dialog
  2. Use a TTS engine, like Eloquence/eSpeak/Vocalizer, which supports multiple languages
  3. Open Notepad++, start typing
  4. Change the Windows input language by pressing Windows Key+Space
  5. Type some more

Expected behavior:

Expect to be able to type the next word without errors.

Actual behavior:

NVDA errors are heard.

feerrenrut commented 6 years ago

This can be worked around by pressing Alt+Tab to focus another application, then returning to Notepad++

Swapnilr1 commented 5 years ago

@feerrenrut Hi, I am new here and want to apply to NV Access for Google Summer of Code 2019.

Does this issue still exist with the latest version? If yes, can I work on this issue to get familiar with the code?

Adriani90 commented 5 years ago

@Swapnilr1 at least from my side, I cannot reproduce this issue in last NVDA Alpha anymore. Tested with eloquence and eSpeak as speech synthesizer. But let's wait for @feerrenrut's confirmation as well.

I wish you all the best for summer of code!

Adriani90 commented 5 years ago

If you want to get familiar with the code by contributing to NVDA, you could also search for issues which are labeled as "goodForNewDev". Here is the link to the issues: https://github.com/nvaccess/nvda/labels/goodForNewDev

Thank you!

lukaszgo1 commented 5 years ago

Given the fact that testing by @Adriani90 shows that it is fixed either something in NVDA has changed, or the testing was done on older build of Windows 10. @Adriani90 would you mint testing lets say with NVDA 2018.1 and if it doesn't work there and works with recent Alpha we can close it IMHO?

Swapnilr1 commented 5 years ago

@Adriani90 Thanks a lot for guiding me.

seanbudd commented 2 years ago

I reproduced this issue with a recent NVDA alpha and notepad++ 8.2.1

Adriani90 commented 6 months ago

Actually, this issue can be reproduced everywhere, and the automatic language recognition does not have to be enabled in NVDA.

Steps to reproduce:

  1. Open NVDA
  2. Press alt+shift or windows+spacebar to switch input language, but keep the alt or the windows key pressed
  3. After one second or so, An input language toggle list will appear, you can now keep the alt or the windows key pressed, and press shift or spacebar to toggle through the input languages.
  4. Release all the pressed keys
  5. Type something on the keyboard, press tab or escape

Actual behavior: NVDA plays errors and does not speak, although the focus or the carret are working properly. It seems the toggle list that appears is an UIA window but NVDA does not have a proper UIA handle for it. After releasing the keys, NVDA does not recognize that the list disappeared and ignores everything related to focus or carret. Although the focus or the carret moves, NVDA ignores it and treats the objects under the focus / carret as non native UIA. I enabled UIA and events in the advanced logging categories, following is written to the log:
