a preview tool, somewhat similar to the gtk3-widget-factory tool, is available, so you can see the current Kvantum theme and your modifications in action.configure active theme: set the toolbar button style, change UI icons and button sizes, enable or disable composite effects or translucent windows, option to respect dark themes, completely remove icons from menus, and much more.built-in Kvantum themes such as Adapta (and Dark), Ambiance, Ark (and Dark variant), Ubuntu Communitheme / Yaru, Gnome, Oxygen, Simplicity, and others (in total there are 30 themes).I find QSvgStyle more difficult to use than Kvantum though, because it only comes with one built-in theme.īesides allowing you to change the Qt 4 and Qt 5 style, Kvantum also features: The idea behind Kvantum - to use SVG images to style Qt widgets - comes from QuantumStyle, which is not developed any more, but is continued as QSvgStyle. Using it, you'll not only be able to theme Qt4 and Qt5 software to match your current Gtk theme almost entirely (as long as your current Gtk theme has a Kvantum theme available), but also configure some Qt theme-related settings.

This is a SVG-based theme engine for both Qt4 and Qt5, KDE and LXQt.

To be able to choose the theme Qt applications are using on your Linux system, tweak some settings, and have an overall better integration with Gnome / Gtk, you can give Kvantum a try. Some Qt applications look out of place in Gnome (and other Gtk-based desktop environments).
