title: Qt Creator: Button Click Signal to make a window pop- up
body: <p>I’m using Qt Creator's Qt Quick and as suggested in the tutorial I made different .qml for every button.</p>
  
  <p>I want when the button is clicked to make a window pop- up. What should I write after </p>
  
  <pre><code>onClicked: 
  </code></pre>
  
  <p>in the mouseArea. </p>
  
  <p>Also how to make a second window (the pop- up one), what should I add to the project so I can design it like the main one? </p>
  
  <p>I read that I have to make a class that inherits with QWidget but I need a bit more information. </p>
  
  <p>A short example would be great.</p>
