Answer 1

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;}");
    }
