title: QML: MouseArea pressed and hover
body: <p>There is a little thing that I absolutely need for the application I am developping: I have to be able to drag an object onto another one and at least one of them should notice that they are intersecting.
  So, I the thing is that one of the items must accept the onEntered signal eventhoug the mouse is pressed form outside.</p>
  
  <p>For example:</p>
  
  <pre><code>import QtQuick 1.0
  
  Rectangle{
      id: base
      width: 500
      height: 500
      MouseArea{ //Even without this mousearea I don't get what i want.
          anchors.fill: parent
          //onPressed:{console.log("big")}
      }
  
      Rectangle{
         id: t
         width: 100
         height: 100
         color: "red"
         MouseArea{
            anchors.fill: parent
            hoverEnabled: true
            onPressed:{console.log("little-press")}
            onEntered:{console.log("little-enter")}
            drag.target: t
         }
       }
  }
  </code></pre>
  
  <p>What I want is to press the mouse button outside the red square, and move it without releasing the button. When the mouse passes over the red rectangle, I want the signal onEntered to be emitted. I don’t understang why it is not emited because onEntered should only care about the mouse beeing inside the mouseArea, not about the buttons.</p>
  
  <p>Any idea of how to do it?</p>
  
  <p>Thank you very much.</p>
