title: Passing an argument to a slot
body: <p>I want to override mouseReleaseEvent with a bunch of QActions and QMenus...</p>
  
  <pre><code>connect(action1, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
  
  connect(action5, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
  
  connect(action10, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
  
  connect(action25, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
  
  connect(action50, SIGNAL(triggered()), this, SLOT(onStepIncreased()));
  </code></pre>
  
  <p>So I want to pass an argument to the slot <code>onStepIncreased</code> (as you can imagine they are 1,5,10,25,50). Do you know how I can do it?</p>
