@tech032142 said in partially update default stylesheet:
how do I get to know the default styles for QGroupBox? styleSheet() returns "" , ty for helping me by the way
You don't, it's not available.
Now that I understand what you want, which I did not before!
I just need to change the border color that's it
See https://doc.qt.io/qt-6/stylesheet-reference.html#border
Shorthand notation for setting the widget's border. Equivalent to specifying border-color, border-style, and/or border-width.
and use https://doc.qt.io/qt-6/stylesheet-reference.html#border-color to set just the color.
