title: What is 'this' keyword in QML
body: <pre><code>Item {
      id: test
      Component.onCompleted: console.log("this is ", this, test)
  }
  </code></pre>
  
  <p>The above code output shows the same pointer to the Item, so what is <code>this</code> keyword in QML?
  Is that the pointer of the nearest QML component and can be used same as <code>id</code>?</p>
