  text: "Add"
  onClicked: {
    var component = Qt.createComponent("add_pq.qml")
    var dialog    = component.createObject(root)
    dialog.open()

    dialog.accepted.connect(function(){
      console.log("ID     :" + window.in_id)
      console.log("Name   :" + window.in_name)
      console.log("Comment:" + window.in_comment)
    })
