It is a Breeze to make QT and GTK applications look good

  Last modified on Sunday 16 July 2017

PROJECT: The Lifecycle of Debian Objects .: I went looking for a desktop style with good support for both Qt and GTK applications. Breeze is the default Qt style of KDE Plasma and the one I chose. I like it!

To setup on Debian ...

Let's go!

Install the breeze package for Qt and gtk3-engines-breeze for GTK ...

$ sudo apt install breeze gtk3-engines-breeze

I am not running KDE or any other desktop environment, so I install a few independent configuration tools ...

$ sudo apt install qt4-qtconfig lxappearance

Run each config tool for its respective environment. Settings are saved to ...

Breeze-dark is an alternative dark colour scheme. Qt5ct handles colours separately from KDE. Create or modify an existing colour scheme and save with a filename ending in .conf to ~/.config/qt5ct/colors. I use this one posted on GitHub. Run qt5ct and in Appearance select the new custom colour scheme. Select breeze-dark in the other config tools.

I add to my ~/.bashrc (which is sourced by ~/.profile) ...


Using a dark theme created a problem for me in Firefox with text entry on some websites. Gmail login, Youtube search, and others would use a near-invisible white font on a white background. Text Contrast for Dark Themes is a Firefox extension that fixed the issue. Good stuff!

Happy hacking!
