title: Assign new slot clicked() for button
body: <p>I have copied several buttons in design form. As result all buttons got the same slot for <code>clicked()</code>. How to create and assign new personal slots for buttons?</p>
  
  <p>UPD</p>
  
  <p>Trying to use <code>Signals &amp; Slots editor</code>. It was empty in the beginning, and I added new one:</p>

  <p>But if I <code>right click on button btnInfoCB-&gt;go to slot.. clicked()</code> , it will point me to the same old method. </p>
