How to apply stylesheet only to parent?

Roberrt

Is there another way to apply a StyleSheet only to the parent widget ignoring her childrens than using her object name?

#widget_1 {
   // ....
}

This way if i change the object name the stylesheet will not work anymore, i wonder if there's any other option?

set style sheet with object name of the parent for example groupBoxSettings
QString settingStyle = " QGroupBox#groupBoxSettings {
background-color: rgb(248,248,248);
border: 1px solid rgb(170, 170, 255);
border-radius: 3px;
border-color:rgb(170, 170, 255);
}";

Other than the #objectName selector the only other way I see is the .ClassName one. For that you would need to make your desired target widget(s) be of a derived class named ClassName you would need to create. See https://doc.qt.io/qt-6/stylesheet-syntax.html#selector-types

Class Selector .QPushButton Matches instances of QPushButton, but not of its subclasses.
This is equivalent to *[class~="QPushButton"].

Having said this: it only talks about not applying to subclasses, not children. So I don't know that this is the right approach. Mind, I do not actually see where the documentation states that #objectName selectors only apply to that widget and not its children, so it's guesswork.
