How to set the progressMinimum() and progressMaximum() of QFutureWatcher

[meganathan]

Hi,

I need to start the progress dialog from 15% percentage. I don't see any like set progressMinimum() or progressMaximum in Qt documentation.
Constructor:
dialog = new QProgressDialog();
dialog->setWindowTitle("Test");
dialog->setMaximumSize(325,85);
dialog->setMinimumSize(325,85);
connect(watcher, SIGNAL(finished()), this, SLOT(FinishedFormat()));
connect(watcher, SIGNAL(progressRangeChanged(int,int)), dialog, SLOT(setRange(int,int)));
connect(watcher, SIGNAL(progressValueChanged(int)), dialog, SLOT(setValue(int)));

inside func:

for(int i=0;i<5;i++)
{
vec->append(i);
}

watcher->setFuture(QtConcurrent::map(*vec,&QthreadTest::felix2Solver));
Display the dialog and start the event loop.
dialog->exec();
watcher->waitForFinished();

Unless I misunderstand, your topic title is confusing. You wish to set the progress values in a QProgressDialog, right? So it has nothing to do with the QFutureWatcher you happen to be utilising?

So what about all the methods in https://doc.qt.io/qt-5/qprogressdialog.html : setMinimum/Maximum/Range/Value()?

Even after setting the dialog->setMinimum() and setMaximum() and removing the connect(watcher, SIGNAL(progressRangeChanged(int,int)), dialog, SLOT(setRange(int,int))); the progressValueChanged is not emitting

on using progressRangeChanged it resets the Qprogress range to (0,0). That is the reason i am trying to set the progressMinimum() and progressMaximum().
