Open File in a class and have access to it in another class

Hi,

In my Dialogclass I open a file

Code:

---

if(file.open(QIODevice::ReadOnly | QIODevice::Text)){
        ui->FileEdit->setText(filepath);
        QByteArray firstlineArray =  file.readLine();
        ui->UpdateProgressBar->setRange(0,(file.size()-firstlineArray.size()));
        firstlineArray.chop(1);
        devicetypeFromFile = firstlineArray.toInt();
        enableUpdateButton(true);
    }

---

Now I want to have access to this file in my WorkerThread Class, because I need to read some lines from this file (it's a file with many hex-lines). The Dialog starts with a click on a Button the WorkerThread.
What is the best way to get the file to my Worker Thread?

1) You create the file on the heap
2) You pass it to the thread's constructor and store it in a member of the thread
3) You all moveToThread on the file object
4) You use the file in the thread and let it delete it when you are done

Cheers,

Okay I created the file on the heap now.
I don't understand the next steps, can you give me an example please? :)

I assume you mean the moveToThread, everything else is basic C++ just like creating on the heap.

Code:

---

file->moveToThread(this);

Ah okay, should have googled it. Thank You.
