How to get the background colour of a QLineEdit?

[Vadi2]

I'd like to colour the text in my QLineEdit - but I also need the colours to adapt to dark themes. How can I tell the background colour of a QLineEdit, so I can adapt my colours appropriately?

@Vadi2 Hi
What do you mean about adapting to dark themes? Not clear to me

[Yunus]

@Vadi2 If you need only the background color you can do it using the below code:

QLineEdit* bg = new QLineEdit();
bg->setStyleSheet("QLineEdit {background-color: black;}");

I don't need to set it, I need to get it's value. If you're using dark mode on macOS or a dark theme on Linux, the widget will be dark - how can I find that out programmatically?

Then you should take a look at QWidget:palette
