Description Nate Graham 2017-05-04 03:29:47 UTC
Linux Distro: openSUSE Tumbleweed Plasma version: 5.9.5 Breeze version: 5.9.5 I prefer the scrollbar style where left-clicking on the scroll track jumps the bar to that location (i.e. the current behavior for a middle-click). To get this behavior in GTK programs, I can set "gtk-primary-button-warps-slider=1" in ~/.config/gtk-3.0/settings.ini. For QT programs, the equivalent setting is QStyle::SH_ScrollBar_LeftClickAbsolutePosition, but Breeze doesn't expose that setting in the GUI, at System Settings > Widget Style > Scrollbars.
Comment 1 Christoph Feck 2017-05-04 09:41:37 UTC
But middle click works?
Comment 2 Hugo Pereira Da Costa 2017-05-04 09:43:37 UTC
(In reply to Christoph Feck from comment #1) > But middle click works? here yes, at least
Comment 3 Nate Graham 2017-05-04 13:11:34 UTC
Yes, it does. I just prefer having the scroll bar move with a left-click in the trough, not a middle-click. Middle-clicking is annoying with a touchpad, which is what I'm using 95% of the time.
Comment 4 Hugo Pereira Da Costa 2017-05-04 13:53:40 UTC
(In reply to Christoph Feck from comment #1) > But middle click works? I wonder if this should not be added to upstream "kstyle" rather than breeze. It is not really a style specific feature, is it? And this way both oxygen and breeze (and any other kstyle derived widget style) would benefit from the extra option. We could then add the extra option not to breeze configuration but rather to the "Fine tuning" tab of the widget style kcm. wdyt ?
Comment 5 Nate Graham 2017-05-04 15:37:26 UTC
That's an excellent idea! You're right, this isn't really Breeze-specific.

I really would love to have the ability to jump to the scrollbar position also with primary mouse button (not middle mouse button) in Qt applications.

Comment 11 Nate Graham 2019-10-04 19:37:38 UTC
I should finally do this.
Comment 12 Björn Feber 2019-10-04 19:41:55 UTC
(In reply to Nate Graham from comment #11) > I should finally do this. The GTK KCM already has this, so when the Application Style KCM has it too and we have the GTK settings synchronization structure then we can set that option for GTK there too.
Comment 13 Nate Graham 2019-10-04 20:06:52 UTC
Yeah. Though upon reflection, I'm gonna put it in the General Behavior rather than Application style since it will affect all scrollbars including in Plasma, which is not an application, so it doesn't make sense IMO to put it in a KCM that's explicitly only about apps. Having started already, it looks like this actually may not be all that hard.

Here's a patch that implements this feature for Qt/KDE apps at least: https://phabricator.kde.org/D25361 Other patches will be required to get scrollbars in Plasma (Bug 384889) and QML-based desktop apps (Bug 412685) to follow suit.

Thank you! Can’t wait to see it fully implemented.
Comment 18 Nate Graham 2019-12-03 00:12:03 UTC
You're very welcome!
Comment 19 tempel.julian 2020-02-14 13:59:26 UTC
Thanks, Nate! Plasma 5.18 really comes with handy changes.

Comment 21 tempel.julian 2020-02-16 10:52:31 UTC
Huh, it works in Okular, but for whatever reason not in LibreOffice Writer with kde5 VCL. There only middle mouse button jumps directly to the position, left mouse button doesn't.
Comment 22 ariasuni 2020-02-16 11:30:44 UTC
I can confirm it works in KDE Applications, VLC, Firefox, Thunderbird, but not in LibreOffice.
Comment 23 Nate Graham 2020-02-16 17:28:56 UTC
That's a bug in LibreOffice. Please file a bug for them, telling them that when using the KDE5 VCL, they should respect QStyle::SH_ScrollBar_LeftClickAbsolutePosition. Then paste a link to the bug report here. :)
