限制样式表对父窗口小部件的影响？

Question

I am setting the background color of a QWidget subclass. When I do this using a stylesheet, the styles of the other components in the QWidget change (eg, the color of a PushButton, and its look changes).

How do I make sure only the background color of the container widget changes and the rest of the child components remain unchanged?

Answer 1

One way is to specify an ID selector. Make sure to set the objectName of your container widget (with setObjectName() ) and use that name in the CSS selector. Assuming a widget named MyContainer , you would use something like this:

QWidget#MyContainer {...}
