Edit file ~/.config/gtk-3.0/settings.ini Add two settings: gtk-alternative-button-order=1 gtk-application-prefer-dark-theme=false Go to System Settings->Application Appearance->GTK. Change the theme here. Reproducible: Always Actual Results: Any content from file is entirely removed and replaced by new settings, event if they have no common keys. Expected Results: The user defined key/value pairs which do not conflict with settings written by KDE/GTK settings wizard should be kept.
Confirming, this can happen indeed. I'll look into this.

Git commit a9f3a3ddcb0b197f96b750323201da438f15c4ad by Nate Graham, on behalf of Mikhail Zolotukhin. Committed on 24/08/2019 at 13:06. Pushed by ngraham into branch 'master'. Keep existing configurations' strings Summary: Gtk configurator has been replacing .gtkrc-2.0 config file with it's own settings, discarding present file contents. Now it only modifies configuration strings, or add them if they are not present at the beginning of the file. This patch also removes redundant configurations, such as including theme from /usr/share/themes gtkrc's, "user-font" style, widget_class and unneeded symlink .gtkrc-2.0-kde4. Those options do not seem needed, as gtk2 applications look the same without these options without any regressions. This was tested on Gimp, Inkscape and BleachBit apps on Manjaro, OpenSUSE and KDE Neon distributions. As for gtk3 ini file - this is not reproducible anymore, any line, which does not hold parameter changeable in configurator, remains in settings.ini. Related: bug 322797, bug 354963 FIXED-IN: 5.17.0 Test Plan: Insert some lines in .gtkrc-2.0 file, that do not represent settings, that configurator changes, check if they are still present after applying new settings. Check if gtk2 apps look identical with or without .gtkrc-2.0-kde4 symlink, with or without similar lines in .gtrkrc-2.0: ``` include "/usr/share/themes/Breeze/gtk-2.0/gtkrc" style "user-font" { font_name="Noto Sans Regular" } widget_class "*" style "user-font" ``` Reviewers: apol, #plasma Reviewed By: apol Subscribers: GB_2, ngraham, plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D21524 M +52 -51 src/appearancegtk2.cpp M +2 -0 src/appearancegtk2.h https://commits.kde.org/kde-gtk-config/a9f3a3ddcb0b197f96b750323201da438f15c4ad
