How To Theme QT Applications in Ubuntu to Make Them Look Native – Gnome – Kvantum Theme Manager
In this video I cover a method of theming QT developed applications using Kvantum so that they look native in Gnome based distribution such as Ubuntu.

Kvantum (by Pedram Pourang, a.k.a. Tsu Jan) is an SVG-based theme engine for Qt, tuned to KDE and LXQt, with an emphasis on elegance, usability and practicality.
Kvantum has a default dark theme, which is inspired by the default theme of Enlightenment. Creation of realistic themes like that for KDE was my first reason to make Kvantum but it goes far beyond its default theme: you could make themes with very different looks and feels for it, whether they be photorealistic or cartoonish, 3D or flat, embellished or minimalistic, or something in between, and Kvantum will let you control almost every aspect of Qt widgets.
Kvantum also comes with many other themes that are installed as root and can be selected and activated by using Kvantum Manager.
HOW TO INSTALL KVANTUM
Kvuntum can usually be installed from your distribution’s repository using your package manager.
For example, in Ubuntu, you would use the following Terminal command:
sudo apt install qt5-style-kvantum
You also need to add a rule to your user profile so that the theme engine will apply the select theme to all QT applications.
See video for that Terminal command since YouTube descriptions cannot contain angled brackets.
Once that is done, log out of your user account, log back in, and then launch Kvantum Manager.
HOW TO USE KVANTUM
Within the application, choose the Change/Delete Theme option, and select a theme that matches the theme currently used by the desktop environment.
