Bug ID: 42038 Summary: Cannot scroll documents being compared in winmerge (Followup to bug 20695) Product: Wine Version: 2.0-rc2 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: user32 Assignee: wine-bugs@winehq.org Reporter: bernhardu@mailbox.org Distribution: ---

Bug #20695 got closed with wine-1.9.7. It really fixes the problem when opening two existing files. (e.g. by menu File - Open)

But if one opens just a new empty file comparison and pastes the two file contents there the scrollbars do not work. (e.g. by menu File - New) (Even without pasting the scrollbars should be moveable a little bit.)

This started like the original bug between 1.1.16-pol and 1.1.17-pol Version 1.9.7-pol shows also the problem as does 2.0-rc2-winehq.

Can this someone confirm?

--- Comment #3 from Bernhard Übelacker bernhardu@mailbox.org --- I did now a git bisect with a lenny chroot between wine-1.1.16 and wine-1.1.17. Did just check if scrollbars are enabled/reacting. It led me really to the same commit:

032356ec379fbac733d4009381338e882672126e is the first bad commit commit 032356ec379fbac733d4009381338e882672126e Author: Nikolay Sivov bunglehead@gmail.com Date: Wed Mar 4 17:38:41 2009 -0500

For completeness: I am using native vb6run (probably just needed for one of the plugins) and native vcrun2008.

--- Comment #7 from Nikolay Sivov bunglehead@gmail.com --- Created attachment 66202 --> https://bugs.winehq.org/attachment.cgi?id=66202 patch

I made some progress on this. Apparently it very much depends on window visibility state, and that's why tests didn't give results.

One remaining issue with attached patch is potentially unrelated to scrollbar handling. The problem is that IsWindowVisible() test fails when compare views are displayed initially. That happens because Afx:xxxx window up parent chain does not have WS_VISIBLE style. While it does on Windows. Full chain ScrollBar -> AfxMDIFrame -> AfxFrameOrView -> AfxMDIFrame -> Afx:xxxxx:xxxx... All windows up to the top one on this list are "WS_VISIBLE"-visible. Anyway, with this patch it's enough to type on char to make scrollbars responsive. Please test and report if you see other problems with it.

--- Comment #8 from Bernhard Übelacker bernhardu@mailbox.org --- Thank you very much taking care of this issue.

I tested with your patch on top of wine-5.0-rc4-57-g2100353861 with WinMerge-2.16.4-Setup.exe.

The scrollbars get activated as the first character is entered into the new compare.

That far the bug could be closed then for me, if that patch would be committed.

However, there seems to be still a difference to running inside native windows: there the scrollbars are enabled just when the new compare got opened. Wine with your patch needs to have additionally a character entered. But at least for WinMerge this is no issue as an empty compare serves no purpose.

But this difference could be related to the visibility issue you found, I guess?

With comparing files I could not find a difference between Wine with your patch and native.

--- Comment #9 from Nikolay Sivov bunglehead@gmail.com --- Yes, exactly. That's the remaining problem I described in comment 7. Removing IsWindowVisible() test will enable scrollbar right away, same as on Windows. But it's a wrong thing to do, as tests show. I'll open another bug for it once original issue is improved.
