Get the string from one class and display it in another class - C++



  • Hello
    I am new to Qt and I am trying to get a string which is displayed in class x to be also displayed in class y
    I have this code in class x
    @QString display(QString::number("Some info");
    ui->tempLabel->setText(display);@

    which returns "some info" , now I created another class
    @void MainWindow: Button @

    and I want to display that string in that class

    can someone please help ?
    thanks

    you have to provide more info.
    Especially about
    @void MainWindow: Button @
    Whats the exact base class of it?

    Since it's a button i can guess that is a QPushButton or a QToolButton, right? If so you can also use setText on it.

    Yes, that is a Qt push button , similar to :
    @void MainWindow::on_pushButton_clicked()
    {
    ui->label->setText("The String");
    // QString display(QString::number("Some info");
    }
    @
    so basically, when that button is pressed, the string from the first class is shown
