Description Philipp A. 2017-05-13 11:30:44 UTC

GTK applications warp the scrollbar slider to the mouse position when the groove is clicked instead of Qt’s page-wise behavior (with warping on middle click)

adding a settings.ini next to the theme’s gtk.css would fix this:

[Settings]
gtk-primary-button-warps-slider=false

Comment 1 grmat 2018-07-02 09:32:07 UTC

It's been configurable in the kcm for a while, maybe not the default, I don't know.

Comment 2 Nate Graham 2018-07-13 20:24:29 UTC

Yes, the KCM should have the opposite default so that it matches the Qt app behavior.

The KCM does have "Scroll one page up/down" (gtk-primary-button-warps-slider=0) as default, but the default config file written by breeze-gtk's kconf_update script doesn't contain gtk-primary-button-warps-slider at all.

Pushed by wbauer into branch 'Plasma/5.12'.

[kconf_update] Add "gtk-primary-button-warps-slider=0" to generated GTK3 config

This brings the default GTK3 settings more in line with Qt's behavior,
and it's also the default in kde-gtk-config's KCM.
