TMemo scrolls up when something is assigned to its SelText property

[Bart]

I would like to inform you that this problem still persists in Lazarus version 1.6.2 (Win64). I think it is not fixed yet.

No it's not fixed, as you could have seen here: http://bugs.freepascal.org/view.php?id=8665.

Patches (cross-platform) are welcome.

Hi again Bart,

Problem still exists in Lazarus version 1.6.4 (Win64).

However, in Bugtracker (http://bugs.freepascal.org/view.php?id=8665) the following is said:

Status   resolved
Resolution   fixed   
Target Version   1.6.4
Fixed in Version   1.7 (SVN)

What does this mean?

What does this mean?

It means that Michl thinks it is fixed (and merged to 1.6.4).
If this is not the case, then the issue should be re-opened.

Note: the implementation (Windows) is now done via a call to

Code: [Select]

  SendMessageW(ACustomEdit.Handle, EM_REPLACESEL, WPARAM(1), LPARAM(PWideChar(UTF8ToUtf16(AText))));

So, basically we let Windows replace the selection.
If that causes scrolling, then I don't know what to do about that.

I guess that fix is not included in version 1.6.4, because the test program "memoseltext.zip (65,613 bytes) 2016-09-07 15:27"  does NOT work as expected in version 1.6.4.

Also, the release notes ( http://wiki.freepascal.org/Lazarus_1.6_fixes_branch ) do NOT mention about issue #0008665 (http://bugs.freepascal.org/view.php?id=8665).

AFAICS none of these revesions are merged to 1.6 fixes branch.
You should ask Michl what the reason for that was, I don't know.
