Qt RadioButtonqss文字居中

可以通过设置样式表来实现RadioButton文字居中。以下是一个示例：

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

QRadioButton::indicator:checked {
    image: url(:/images/radio_checked.png);
}

QRadioButton::indicator:unchecked {
    image: url(:/images/radio_unchecked.png);
}

QRadioButton::indicator:checked:disabled {
    image: url(:/images/radio_checked_disabled.png);
}

QRadioButton::indicator:unchecked:disabled {
    image: url(:/images/radio_unchecked_disabled.png);
}

QRadioButton::indicator:hover {
    border: none;
}

QRadioButton::indicator:checked:hover {
    border: none;
}

QRadioButton::indicator:unchecked:hover {
    border: none;
}

QRadioButton::indicator:checked:focus {
    border: none;
}

QRadioButton::indicator:unchecked:focus {
    border: none;
}

QRadioButton::indicator:checked:pressed {
    border: none;
}

QRadioButton::indicator:unchecked:pressed {
    border: none;
}

QRadioButton::indicator:checked:disabled:hover {
    border: none;
}

QRadioButton::indicator:unchecked:disabled:hover {
    border: none;
}

QRadioButton::indicator:checked:disabled:focus {
    border: none;
}

QRadioButton::indicator:unchecked:disabled:focus {
    border: none;
}

QRadioButton::indicator:checked:disabled:pressed {
    border: none;
}

QRadioButton::indicator:unchecked:disabled:pressed {
    border: none;
}

QRadioButton::indicator:checked:indeterminate {
    image: url(:/images/radio_indeterminate.png);
}

QRadioButton::indicator:unchecked:indeterminate {
    image: url(:/images/radio_indeterminate.png);
}

QRadioButton {
    padding-left: 25px;
}

QRadioButton::indicator {
    position: absolute;
    top: 0px;
    left: 0px;
}

在这个样式表中，我们将RadioButton的padding-left设置为25px，以便将RadioButton的左边距离留出一定的空间。然后，我们使用绝对定位来将RadioButton的指示器放在左侧，同时将其宽度和高度设置为20px。

最后，我们可以根据需要设置RadioButton的checked和unchecked状态下的图像，以及鼠标悬停、按下、失效等状态下的样式。
