[SOLVED] Passing arguments to a run() method of QThread

Passing arguments to a run() method of QThread

I've subclassed my Qthread so I can implement my code in run() method. I have to pass it some parameters,

I tried it like this, so what's wrong in here?

class QMyThread :
    public QThread
{
public:
    QMyThread();
    ~QMyThread(void);
    virtual void start(FILE *data, int sock, int bits);

protected:
    virtual void run(FILE *data, int sock, int bits);
};

run method;

void QMyThread::run(FILE *data, int sock, int bits)
{
//do stuff
}

start the thread:

QMyThread *thread;
thread->start(datafile, sockint, bitsint);

first it says the thread might not be initialized and then it crashes in the start() method with SIGSEGV error. Anyone can help me?

Solution

You shouldn't be subclassing the QThread class as this is no longer the recommended way of using QThread.

To answer your question, couldn't you just make those parameters members of your class and assign their values through setters or its contructor?
