Description Yousuf Philips (jay) (retired) 2014-10-06 07:59:19 UTC
When elements in the sidebar take up more space than is available, a scrollbar appears. The scrollbar scrolls correctly if you drag the slider up and down, or if you use the mouse scroll wheel to move up and down. The scrollbar doesnt scroll correctly when you click in the empty space between the scrollbar arrows and the slider. It moves at 1 pixel per click.

I am setting bug status NEW and o/s Windows.  Jay, is it other than an
accident that you reported o/s All?  I do not see the slowdown in the
daily dbgutil bibisect repository.


Running a tinderbox build from 2014-10-15 02:45:20 on Windows Vista, I
see:

(*) In the sidebar, clicking in the space between the slider and the
    scrollbar arrow scrolls by one pixel.

(*) Similarly the scrollbar arrows in the sidebar.

(*) In the document area, a click in the space between the slider and
    the scrollbar arrow scrolls by about the height of the document
    area.

(*) The scrollbar arrows in the document area scrolls by about a
    centimeter.

My Windows computer does not have a mouse wheel.

Terry.

Setting o/s back to All.  I can't imagine what I was thinking.

Thanks Terry for noticing this, as this also scrolls by 1 pixel.

The Properties pane in Impress is similarly afflicted with slow
scrolling.
Comment 5 Matthew Millar 2015-04-17 13:07:05 UTC
Fault still exists in 4.4.1.2, however I'm only experiencing the speed issue in the 'Properties' tab of the sidebar.

Whilst there are scrollbars in all except the 'Styles and Formatting' tab, 'Properties' is the only tab with a scrollbar for the actual bar (due to the content exceeding the bar); all others are scrollbars within objects, e.g. lists with items which exceed the list object's capacity, but with the list object filling and not exceeding the bar.
Comment 6 Terrence Enger 2015-05-29 02:12:51 UTC
And I see the problem continues on Vista in daily build 2015-05-28.
However, I do not see the problem in (chroot environmet to) debian-sid
with daily dbgutil bibisect version 2015-05-28.
Comment 7 Yousuf Philips (jay) (retired) 2015-10-30 13:58:35 UTC
@Bjoern: As you stated that you fixed scrollwheel in sidebar, any possibility to see what is wrong here.

This seems to be about the deck are of the sidebar, not about the TabBar area.

Still an issue - small changes (SB_LINEUP/SB_LINEDOWN) have the same effect as large scale (SB_PAGEUP/SB_PAGEDOWN) [1]. EASYHACK?

NEEDINFO for the code pointers.
Comment 13 Xisco Faulí 2016-09-15 15:26:57 UTC
Removing keyword 'needsDevEval' as this bug is an easyHack
Comment 14 jani 2016-09-17 07:17:56 UTC
this is not an easyhack, our renderer is quite complicated

----
With Writer running on debian-buster, I have looked at the sidebar.
With SAL_USE_VCLPLUGIN=gtk3, the sidebar lack up/down arrows on the
scrollbar, and a click above or below the slider in the scrollbar
moves the view accordingly.  With SAL_USE_VCLPLUGIN=gen, the up/down
arrows on the scrollbar move the pane by about 1/3 the height of the
spacing and indent controls and a click above or below the slider
moves the pane by the distance represented by the height of the
slider.

I am setting bug status WORKS FOR ME.

Still behaves the way described on first (Jay's) comment.

(I was sure to have been me opening such bug… perhaps a duplicate? :)
Comment 20 Gabriele Ponzo 2020-03-01 07:52:52 UTC
Indeed: Bug 105919, already marked here as a duplicate, was mine :)
