QT枚举类型与字符串类型相互转换

#include <QtCore/QMetaEnum>

int main() {
    QMetaEnum metaEnum = QMetaEnum::fromType<Qt::Alignment>();

    //字符串转枚举值
    Qt::Alignment alignment = (Qt::Alignment)metaEnum.keyToValue("Qt::AlignLeft");
    alignment = (Qt::Alignment)metaEnum.keysToValue("Qt::AlignLeft | Qt::AlignVCenter");

    //枚举值转字符串
    const char* s = metaEnum.valueToKey(Qt::AlignCenter);
    return 0;
}

QTabBar#CustomTabBar {
    /* Qt::AlignmentFlag定义 */
    qproperty-text_align: "AlignLeft | AlignVCenter";
}
