title: using loader in qml
body: <p>I have multiple QML files. I just want to link them. Then I want to return to my home page from every page I navigate to. I am using loader in every page
  Here is my code.</p>
  
  <pre><code>import QtQuick 1.1
  Rectangle{
      id:welcome
      width:480
      height:272
      Loader{
          id:loader
          focus:false
          anchors.fill: parent
      }
      gradient: Gradient {
          GradientStop { position: 0.0; color: "light blue" }
          GradientStop { position: 1.0; color: "blue" }
      }
      Text{
          text:"\n\t\tPRESS ENTER"
          font.bold:true
          font.pointSize: 17
      }
      Button {
      id: wel
          height:30;
          x:parent.width/2-30
          y:parent.height/2-30
          focus:true
          border.color:"black"
          opacity: activeFocus ? 1.0 : 0.5
          Text{   
              text:"WELCOME"
              anchors.horizontalCenter:wel.horizontalCenter;
              anchors.verticalCenter:wel.verticalCenter;
          }   
          Keys.onReturnPressed: {
              wel.focus=false
              loader.focus=true;
              anchors.fill=parent
             loader.source="Home.qml";
              //welcome.visible=false;
          }
      }
  }
  </code></pre>
  
  <p>My question is whenever I click on the button its loading new file. But the welcome page will not go. Both the file's will be overlapped. When I did visible=false complete UI will go. I get a white screen.
  Can any one help me fix this problem? 
  How to load other file?</p>
