Theming
Theming
Every widget asks the current theme for its colours, sizes, fonts and icons. Change the theme and every window repaints with the new values. You do not restyle widgets one by one.
Bellui’s default theme follows Material Design 3 (MD3). It has a light and a dark variant and follows the operating system’s appearance setting. Its colours are generated from one primary colour.
