There is a new package available for Sparkers: Kvantum.

What is Kvantum?

Kvantum is an SVG-based theme engine for Qt4/Qt5 and KDE, i.e. a program for styling Qt applications with SVG images, with an emphasis on elegance, usability and practicality.

Kvantum comes with a default dark theme, inspired by the default theme of Enlightenment. Creation of realistic themes like that for KDE was my first reason to make Kvantum but it allows themes with very different looks and feels, whether they be photorealistic or cartoonish, 3D or flat, embellished or minimalistic, or something in between.

Kvantum also has extra themes, that are installed as root with Qt5 installation and can be selected and activated by using Kvantum Manager.

The core idea of Kvantum, namely using of SVG images for drawing Qt widgets, is taken from QuantumStyle (not developed anymore but continued as QSvgStyle at

apt update
apt install kvantum

The Kvantum package is available for Sparky 4 and Sparky 5 as well.


The project developer is Pedram Pourang, a.k.a. Tsu Jan.

A new application is available for Sparkers: Qt5ct.

This utility allows users to configure Qt5 settings (theme, font, icons, etc.) under DE/WM without Qt integration.

Qt5ct could use qt5 gtk theme, KDE breeze theme, the fusion theme, QtCurve theme and many more. Each style could be customized further by changing the color schema.

Installation via Synaptic or APT:
sudo apt update
sudo apt install qt5ct

Then reboot.
