如何对QT两个TableWidget中的tab进行切换。仅仅是两个_qtabwidget切换tab信号

1、定义静态变量static int i;

2、

 i=1;

    connect(ui->tabWidget, SIGNAL(tabBarClicked(int)) ,this,SLOT(slot_bt_close()));

3、槽函数实现

void MainWindow::slot_bt_close()

{

    if(i==1)

    {

        qDebug()<<"slot_bt_close"<<endl;

        ui->add_Button->close();

        ui->refesh_Button->close();

        ui->delete_Button->close();

        ui->modifi_Button->close();

        ui->clear_Button->close();

        ui->select_Button->close();

        i=0;

    }else if(i==0)

    {

        qDebug()<<"slot_bt_open"<<endl;

        ui->add_Button->show();

        ui->refesh_Button->show();

        ui->delete_Button->show();

        ui->modifi_Button->show();

        ui->clear_Button->show();

        ui->select_Button->show();

        i=1;

    }

}
