А вот и наглядное использование контроля стилей через свойства виджета. Билиотека qt-material.
В этом разделе написано, что через свойство class можно контролировать цвет кнопки, по аналогии с css стилями.
btn_danger.setProperty('class', 'danger')
btn_warning.setProperty('class', 'warning')
btn_success.setProperty('class', 'success')

Matter exists in different states:
● Solid – fixed shape and volume, particles tightly packed.
● Liquid – fixed volume, no fixed shape, particles slide past each other.
● Gas – no fixed shape or volume, particles far apart.
● Plasma – like gas but particles are charged.
● Glass – between solid and liquid, amorphous.
● Superfluid – liquid with no resistance near absolute zero.
● Bose-Einstein Condensate – particles act as one quantum entity.
● Fermionic Condensate – similar to Bose-Einstein but formed by fermions.
● Dropleton – quantum liquid of electrons and holes.
● Degenerate Matter – exists under extreme pressure inside stars or planets.
Matter changes state when energy is added or removed.
