Description Sergei Andreev 2009-06-09 23:18:09 UTC

Version:           4.2.4 (KDE 4.2.4) (using 4.2.4 (KDE 4.2.4), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.28-12-generic

1. Create a long Page - a scrollbar must appear.
2. Go to the end of the Page.
3. Insert Rule Line (horizontal bar).

Screen jumps to beginning of the page and you have to scroll to previous position manualy with mouse or hit Arror, Space or Enter buttons.

Very annoying behaviour when you editing/formatting some big note.

Yes you are right about this. the page should stop after the line instead of going to the start of of the page. I found out about this when i give it a try. Hope Steph would look on this.

The same happens to me. This bug was added almost a year ago, I still can reproduce it.

[KRichTextEdit] Fix scroll jumping around when horizontal rule is added

Summary:
Due to Qt bug 83605, it's not a good idea to `setTextCursor` while the cursor
is inside `beginEditBlock / endEditBlock` (scrollbar might jump to the top),
see KDE bug 195828. It's sufficient to move `setTextCursor` outside to fix it.
(it's never too late... :)

This patch also adds a test for this case (which currently fails due to
regression, see {D28819} and {D28964} for the fix).

Test Plan:
 1) Apply {D28964}
 2) `ctest`
