Question

I’m a QT newbie. I have a class extend from widget like:

class myclass: public Qwidget
{
Q_OBJECT
public:
  void myfunction(int);
slots:
  void myslot(int)
  {
    //Here I want to put myfunction into a thread
  }
  ...
}

I don’t know how to do it. Please help me.

Answer 1

Add a QThread member then in myslot move your object to the thread and run the function.

class myclass: public Qwidget
{
   QThread thread;
public:
slots:
  void myfunction(int); //changed to slot
  void myslot(int)
  {
    //Here I want to put myfunction into a thread
    moveToThread(&thread);
    connect(&thread, SIGNAL(started()), this, SLOT(myfunction())); //cant have parameter sorry, when using connect
    thread.start();
  }
  ...
}

My answer is basically the same as from this post: Is it possible to implement polling with QThread without subclassing it?
