QProgreesDialog updating from within threadable function

[Astrologer]

Hi there. I have got a question for you, guys, which I really would like you to help me with.
I have got a function with QString parameter and within the function long-time procedures take place. I execute this function with QFuture but I would like for the progress of operation to be indicated. For example I can declare the variable inside the function and which varies between 0 and 100. How can I arrange it and bind to QProgressDialog? Here goes the snippet:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    connect(this->ui->test_button, SIGNAL(clicked()), SLOT(call_algorithm()));
}
 
void MainWindow::call_algorithm()
{
    QFuture<void> future = QtConcurrent::run(algorithm, this->ui->jpg_name_edit->text());
}
 
void algorithm(QString image_name)
{
//some code here =)
}

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    connect(this->ui->test_button, SIGNAL(clicked()), SLOT(call_algorithm()));
}

void MainWindow::call_algorithm()
{
    QFuture<void> future = QtConcurrent::run(algorithm, this->ui->jpg_name_edit->text());
}

void algorithm(QString image_name)
{
//some code here =)
}

In QtConcurent functions you can use either static functions ( like your algorythm ) or your class's member function, where you can emit a signal to show the progress of computations. See binding section in QtConcurent docs

I have solved that. Thanks anyway.

Hi Astrologer,

Could you post an example with the solution you found and adopted?

Thanks,
