QTabWidget关闭tab重新打开界面数据不重新初始化

求QT5 QTabWidget关闭tab重新打开界面数据不需要重新初始化怎么解决？

用隐藏代替删除


    if (m_hide) {
        ui->tabWidget->setTabEnabled(1, false);
        ui->tabWidget->setStyleSheet("QTabBar::tab:disabled {width: 0; color: transparent;}");
    }
    else {
        ui->tabWidget->setTabEnabled(1, true);
        ui->tabWidget->setStyleSheet("QTabBar::tab:disabled {width: 20; color: transparent;}");
    }
