How to make KDE applications look native in GNOME?

Is there a way to make KDE applications (like digiKam) look native in GNOME?

Solution 1:

First you need the KDE's "System settings" application by installing systemsettings from the Software Center.

Search the dash for System settings and launch it . Then make the following changes:

• under Style → Applications → Widget style, select GTK+
• under Colors, select the colours to match your GTK theme or download the Ambiance colour scheme .
• under Icons → Theme, select the icon theme you are using in GTK apps
• under Fonts select "Ubuntu", size 11

Solution 2:

In Ubuntu 18.04, what worked for me was:

sudo apt-get install qt5-style-plugins

This is taken from the ArchLinux documentation. It also recommends setting the QT_QPA_PLATFORMTHEME=gtk2 environment variable, but I did not need that.
