Original Pull Request: https://github.com/microsoft/terminal/pull/4826

State: closed
Merged: Yes

Summary of the Pull Request

This notifies automation clients (i.e.: NVDA, narrator, etc...) of new output being rendered to the screen.

References

Close #2447 - Signaling for new output and cursor
Close #3791 - fixed by signaling cursor changes

Detailed Description of the Pull Request / Additional comments

  • Added tracing for UiaRenderer. This makes it easier to debug issues with notifying an automation client.
  • Fire TextChanged automation events when new content is output to the screen.

Validation Steps Performed

Verified with NVDA [1]

Narrator

Narrator works better, but is unable to detect new output consistently. There is no harm for narrator when this change goes in.
