    Hi
    I put this code and get error

    void MainWindow::on_pushButton_clicked()
    {
        QDate myDate= ui->dateEdit->date();
        QString dateString = myDate.toString();
        label->setText(dateString);
    
    }
    

    Error:

    C:\Users\armin\Documents\StoMar\mainwindow.cpp:21: error: 'label' was not declared in this scope
    label->setText(dateString);
    ^

      Hi,

      It's the same error you already had in your other thread. You don't have any object named label.

          I solved.
          I added ui in my code.

          void MainWindow::on_pushButton_clicked()
          {
              QDate myDate= ui->dateEdit->date();
              QString dateString = myDate.toString();
              ui->label1->setText(dateString);
          
          }

            Hi
            All you add via Designer is available via UI->
            for the same class.
            Its created when you run
            ui ( new Ui::MainWindow ) {
            ui->setupUi ( this );
            Which is inserted when you create the widget via Designer/Creator
            (in the constructor)
