[Interest] How to pass parameter from Menu/Action to SLOT()

[Nicholas Yue]

Hi,

  I am programmatically generating a menu, each menu item has a unique
name/label

  How can I determine which of the generated menu was clicked ?

```
void MainWindow::init()
{
:
:
QMenu *specialists = menuBar()->addMenu("&Specialists");
if (!_engine.getSpecialistsManager().registeredSpecialists().empty()){

std::vector<QAction*>
specialistMenuAction(_engine.getSpecialistsManager().registeredSpecialists().size());

size_t specialistMenuActionIndex = 0;
for (auto iter =
_engine.getSpecialistsManager().registeredSpecialists().begin();
iter != _engine.getSpecialistsManager().registeredSpecialists().end();
++iter,specialistMenuActionIndex++)
{
           specialistMenuAction[specialistMenuActionIndex] = new
QAction((boost::format("&%1%")%(iter->first)).str().c_str(), this);

 specialists->addAction(specialistMenuAction[specialistMenuActionIndex]);
           connect(specialistMenuAction[specialistMenuActionIndex],
SIGNAL(triggered()), this, SLOT(specialistMenuHandler()));
}
}
:
:
}
```

```
void MainWindow::specialistMenuHandler()
{
  std::cout << "MainWindow::specialistMenuHandler()" << std::endl;
}
```

Cheers
