If I want to update a QProgressBar on the view layers from a loop on the logic layer (such as each iteration will update the progress bar), what is the proper way to do that?
Thanks
class LogicClass : public QObject
{
Q_OBJECT
public:
explicit LogicClass(QObject *parent = 0);
int max(){ return 100; }
int min(){ return 0; }
void emit50(){ emit signalProgress(50); }
signals:
void signalProgress(int);
public slots:
};
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
LogicClass logic;
ui->progressBar->setMaximum( logic.max() );
ui->progressBar->setMinimum( logic.min() );
connect( &logic, SIGNAL( signalProgress(int) ), ui->progressBar, SLOT( setValue(int) ) );
logic.emit50();
}
