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 https://github.com/DexterMagnific/QSvgStyle).
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.
