kill qprocess with parent

Question

This is the code to execute a command and return the output. The problem is that if I kill the testProcess, "ping" keeps on going. I tried also with

QObject *parent;
parent=new QObject;
myprocess *p;
p=new myprocess(parent);

sorry for my english

testProcess.h:

class myprocess : public QProcess{
    Q_OBJECT
public:
    myprocess( QObject *parent = 0 );
protected slots:
void readyOut();
void readyErr();
};

testProcess.cpp main:

myprocess *p;
p=new myprocess;

QObject::connect(p,SIGNAL(readyReadStandardOutput()),p,SLOT(readyOut()));
QObject::connect(p,SIGNAL(readyReadStandardError()),p,SLOT(readyErr()));

p->start("ping -t www.google.com");

p->waitForFinished(60000);

delete p;

If you want your process to close when the application closes then you could connect to the core application aboutToQuit() signal. It would look something like this

connect( QCoreApplication::instance(), SIGNAL(aboutToQuit()), p, SLOT(kill()));

There is also a terminate() slot in the process that could be used, but I think kill() may be more appropriate in your situation.
