One signal more slots

[paolom]

I can't do this cause the object lives in different threads.

I've something like this:

class Manager : public QObject
{
    Q_OBJECT
 
    signals:
         void invokeObjMethod(int);
 
    private:
        void initManager(){
 
            for ( int idx = 0 ; idx < n; idx++){
                QThread * th = new QThread(this);
                MyObject * obj = new MyObject(idx);
                connect(this,SIGNAL(invokeObjMethod(int)),obj,SLOT(doSomething(int)));
                obj->moveToThread(th);
                th->start();       
           }
       }
}
 
class MyObject : public QObject
{
      Q_OBJECT
      public:
          MyObject(int idx, QObject * parent = 0)
                :QObject(parent),
                m_index(idx){}
 
     private:
          int m_index;
 
     public slots:
          void doSomething(int idx){
                  if ( idx != m_index)
                        return;
 
                  ...do Something ...
           }
}

class Manager : public QObject
{
    Q_OBJECT

    signals:
         void invokeObjMethod(int);

    private:
        void initManager(){

            for ( int idx = 0 ; idx < n; idx++){
                QThread * th = new QThread(this);
                MyObject * obj = new MyObject(idx);
                connect(this,SIGNAL(invokeObjMethod(int)),obj,SLOT(doSomething(int)));
                obj->moveToThread(th);
                th->start();       
           }
       }
}

class MyObject : public QObject
{
      Q_OBJECT
      public:
          MyObject(int idx, QObject * parent = 0)
                :QObject(parent),
                m_index(idx){}

     private:
          int m_index;

     public slots:
          void doSomething(int idx){
                  if ( idx != m_index)
                        return;

                  ...do Something ...
           }
}

When the manager emit the signal invokeObjMethod(int) all the objects invoke their slot but only one do something.
I want to know if this is the right way or there are other best solu
