QGroupBox qss code

Here is an example of QGroupBox QSS code:

QGroupBox {
    border: 2px solid gray;
    border-radius: 5px;
    margin-top: 10px;
}

QGroupBox::title {
    subcontrol-origin: margin;
    subcontrol-position: top left;
    padding: 0 10px;
    font-weight: bold;
}

QGroupBox::indicator {
    width: 20px;
    height: 20px;
}

QGroupBox::indicator:checked {
    image: url(checked.png);
}

QGroupBox::indicator:unchecked {
    image: url(unchecked.png);
}

This code sets the border, border radius, and margin for the QGroupBox. It also styles the title by setting the padding and font weight. The QGroupBox indicator is styled with a width and height, and different images are used for when it is checked or unchecked.
