Incorrect reading of long lines in Notepad2 and its descendants' Scintilla control #885

In Notepad2 and its descendants, if word wrap is turned on the wrapped lines are incorrectly read by NVDA. Instead of reading the subsequent lines, NVDA repeats the whole line.
E.g. suppose we have a long line which is wrapped to 3 lines. At the first line NVDA reads all the 3 lines together (i.e. as if it wasn't wrapped at all). On the following two lines, NVDA repeats the line again, instead of reading the actual line content. As a result, we have one line wrapped to 3 lines, but NVDA reads all the 3 lines at once, and repeats it on the following 2.
Blocking #3128

(In #3128) Duplicate of #885.

From memory, I don't believe Scintilla's API provides a way to fetch "soft" lines, so I'm not sure we can fix this without a change to Scintilla. However, this needs to be investigated more thoroughly.

I said this in the duplicate, but for completeness will mention it again here: this also happens in Inform 7. Fortunately, scintilla is not unbelievably popular, at least not yet.

Well, I take back my prior comment. I decided that I finally needed a proper programming editor, and...Scintilla is unbelievably popular after all.
Just as a sidenote, selecting the wrapped part of the line does work as expected at least in notepad++.

I think I've managed to implement this. Please try this build: http://community.nvda-project.org/try/scintillaWordWrap/nvda_snapshot_try-scintillaWordWrap-9263,26f3840.exe

I've encountered the same problem in Notepad++, and you trial snapshot solves the problem yes, you may merge it.

Sorry, I've not been not checking my e-mail a lot lately. I'll try this snapshot momentarily.

Comment 10 by camlorn on 2013-06-18 18:44
I can confirm that it works as well and sorry again for not seeing this sooner.

Milestone changed from None to 2013.2

An issue was identified where if reading text with the review cursor could loop back on itself if line wrapping was enabled and part of the wrapped line was above or below the bounds of the window. This should have been fixed and can be tested in the following try build:
This has been tested with Notepad++ but not with things such as SciTE. If testing with these, try to load a big document that does not entirely fit on the screen. Keep the caret (insertion point) at the top of the document, but move to the bottom of the document with NVDA's review cursor. Then see if you can read the lines with the review cursor going up the document.

In [435e8f0]:

In Scintilla controls, lines are now reported correctly when word wrap is enabled.

There is no direct way to retrieve information about wrapped lines, but this can be achieved using screen coordinates.
Fixes #885.

Removed labels: incubating
