<![CDATA[Slot function pointer with arguments]]>I'm trying to use setText() in a slot on connect without using a lambda. Here's what I have:

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QApplication::connect(timeThread, &QThread::started, timer, &CustomTimer::start);
    QApplication::connect(timeThread, &QThread::finished, ui->timeLabel, &QLabel::setText("Done"));
}

I'm just unsure how to call the function if it has an argument. Any guidance is appreciated.

Thanks!

Yeah, I didn't know if I needed to create a class to inherit from QLabel for that. Need to promote a label in designer but I wanted to make sure that was the simplest way.

Thanks for the quick response!

*.h

private slots:
    void handle_finished();

*.cpp

void MainWindow::handle_finished(){
    ui->timeLabel->setText("Done");
}

and the connection:

connect(timeThread, &QThread::finished, this, &MainWindow::handle_finished);
