Using QCustomEvent in QThread

[Dmitry]

Hi! I'am sorry to my english.
Why code line

delete dbe;

delete dbe;

To copy to clipboard, switch view to plain text mode 

cause for Segmentatuon fault, if this line to follow after code

DBEvent* dbe = new DBEvent(n,x,y);
QApplication::postEvent( receiver, dbe );
...
msleep(1);
//delete dbe;

DBEvent* dbe = new DBEvent(n,x,y);
QApplication::postEvent( receiver, dbe );
...
msleep(1);
//delete dbe;

Аbove code from within QThread::run().

The class DBEven implementation:

class DBEvent : public QCustomEvent {
public:
   DBEvent( int n_, double* px_, double* py_) :
   QCustomEvent( 65432 ), n(n_), px(px_), py(py_) {
   }
...
private:
   int n;
   double *px;
   double *py;
};

class DBEvent : public QCustomEvent {
public:
   DBEvent( int n_, double* px_, double* py_) :
   QCustomEvent( 65432 ), n(n_), px(px_), py(py_) {
   }
...
private:
   int n;
   double *px;
   double *py;
};

Who killed CustomEvent?

Thanks.
