Context menu / connect with parameters

[pietrom]

I have a problem with context menus. I would like to create one in a dynamic way, i.e. passing a set of string variables:

void MyClass::contextMenu(std::vector<QAction*>& labelsAct)
{
    for(size_t i = 0; i < labelsAct.size(); ++i)
    {
        QObject::connect(labelsAct[i], SIGNAL(mySignal(int)),
                         this, SLOT(doSomething(int)));
    }
}

void MyClass::contextMenu(std::vector<QAction*>& labelsAct)
{
    for(size_t i = 0; i < labelsAct.size(); ++i)
    {
        QObject::connect(labelsAct[i], SIGNAL(mySignal(int)),
                         this, SLOT(doSomething(int)));
    }
}

To copy to clipboard, switch view to plain text mode 

This is the message I get at runtime:

Object::connect: No such signal QAction::mySignal(int)

Object::connect: No such signal QAction::mySignal(int)

To copy to clipboard, switch view to plain text mode 

doSomething(int) is defined in the MyClass class.
mySignal(int) is declared in the MyClass class; why does it look for the signal in QAction?

If I remove the int parameters from those function (definitions), the connect works correctly. But I need those parameters.

Thank you...

QAction doesn't has such signal
try to do next

...
connect(this, SIGNAL(mySignal(int)), SLOT(doSomething(int)));
...
 
void MyClass::contextMenu(std::vector<QAction*>& labelsAct)
{
    for(size_t i = 0; i < labelsAct.size(); ++i)
    {
        QAction *action = labelsAct[i];
        action->setProperty("myValue", i);
        QObject::connect(action, SIGNAL(triggered()),
                         this, SLOT(mySlot()));
    }
}
 
void MyClass::mySlot()
{
      QAction *action = qobject_cast<QAction *>(sender());
      if (!action)
         return;
      int myValue = action->property("myValue").toInt();
      emit mySignal(myValue);
}

...
connect(this, SIGNAL(mySignal(int)), SLOT(doSomething(int)));
...

void MyClass::contextMenu(std::vector<QAction*>& labelsAct)
{
    for(size_t i = 0; i < labelsAct.size(); ++i)
    {
        QAction *action = labelsAct[i];
        action->setProperty("myValue", i);
        QObject::connect(action, SIGNAL(triggered()),
                         this, SLOT(mySlot()));
    }
}

void MyClass::mySlot()
{
      QAction *action = qobject_cast<QAction *>(sender());
      if (!action)
         return;
      int myValue = action->property("myValue").toInt();
      emit mySignal(myValue);
}
