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";
}

QPushButton btn;
int receivers = btn.receivers(SIGNAL(clicked(bool));
