    ... I don't get it, can you make a quick example? In my opinion the "delegate" just delegate the model to TimelineDeviceDetail and to make TimelineDeviceDetail visible I have to declare it somewhere in TimelineVertical...

      From your earlier posts i assume that you have a separate TimelineDeviceDetail.qml file. So define an id here.
      @
      import QtQuick 2.0

      Rectangle {
      // id: rectangle2
      id: detailRectangle
      width: 0
      height: 200
      color: "#FFFFFF"
      radius: 4
      anchors.right: parent.right
      ...
      @

      and it will be accessible as before.

          So just define an id (detailRectangle) there and it will be accessible. See my earlier edited post.

            So you mean:

            in TimelineDeviceDetail.qml

            @
            //detail
            Rectangle {
            id: detailRectangle
            width: 0
            height: 200
            color: "#FFFFFF"
            radius: 4
            anchors.right: parent.right
            anchors.rightMargin: 100
            opacity: 0.70
            anchors.left: timelineLineRectangle.right
            anchors.leftMargin: 165
            anchors.top: timeslotRow.bottom
            anchors.topMargin: 0
            visible: true //debugging: make it false

                Text {
                    id: euroText
            

            // Component.onCompleted: console.log("euro: " + timeslotmodel.euro)
            text: model.euro
            anchors.top: parent.top
            anchors.topMargin: 20
            anchors.left: parent.left
            anchors.leftMargin: 20
            font.pixelSize: 12
            }

                Text {
                    id: kwhText
            

            // Component.onCompleted: console.log("kwh: " + timeslotmodel.kwh)
            text: model.kwh
            anchors.top: parent.top
            anchors.topMargin: 20
            anchors.horizontalCenter: parent.horizontalCenter
            font.pixelSize: 12
            }

                Text {
                    id: timeText
                    text: model.time
                    anchors.top: parent.top
                    anchors.topMargin: 20
                    anchors.right: parent.right
                    anchors.rightMargin: 20
                    font.pixelSize: 12
                }
            

            //...
            @

            and int TimelineVertical.qml:

            @
            Repeater {
            id: deviceRepeater
            model: timeslotmodel
            delegate: TimelineDeviceDetail {}
            // Component.onCompleted: console.log("euroValueTest: " + timeslotmodel.euro)
            Button {id: deviceImageButton; anchors.verticalCenter: parent.verticalCenter; iconSource: deviceImage; width: 100; height: 100; /onClicked: setVisibleEffect(detailRectangle, deviceItem);/ style: TimelineDeviceButtonStyle{} }

                                    }
                                }
                            }
                        }
                    }
            
                     TimelineDeviceDetail {} //set the view where I need it
            

            @

            But than I get the same error as before:

            qrc:///TimelineDeviceDetail.qml:22:19: Unable to assign [undefined] to QString
            qrc:///TimelineDeviceDetail.qml:33:19: Unable to assign [undefined] to QString

              I put the code from TimelineDeviceDetail.qml back to TimelineVertical.qml to make it simple. It turned out that it's even there not accessible...

              @
              Row {
              id: deviceRow
              spacing: 20

                                      Repeater {
                                          id: deviceRepeater
                                          model: timeslotmodel
                                          delegate: detailRectangle
              
                                          Button {id: deviceImageButton; anchors.verticalCenter: parent.verticalCenter; iconSource: deviceImage; width: 100; height: 100; onClicked: setVisibleEffect(detailRectangle, deviceItem); style: TimelineDeviceButtonStyle{} }

                If you define delegate in same file then you will need to encapsulate it in Component.

                Going to the previous, you have again added TimelineDeviceDetail there. Please remove it or you will get the same errors. Please refer my earlier posts.
                TimelineDeviceDetail will be accessible using its id even if it is specified in separate file.

                  Ok thanks for that advise. Can you please tell my if I remove "TimelineDeviceDetail" from "TimelineVertical" how to include the TimelineDeviceDetail in TimelineVertical? Or can you make "will be accessible using its id..." a little bit more clear?

                  Thanks

                    Ok. Just revisited the posts. I too got confused. Lots of code here :)
                    First Why would you want TimelineDeviceDetail outside the delegate as it has already been assigned as delegate to repeater ?

                    Just created a small example related to above:
                    @
                    //TimelineDeviceDetail.qml
                    import QtQuick 2.3
                    Rectangle {
                    id: detailRectangle
                    y: index*40
                    width: 300
                    height: 40
                    color: "lightgray"
                    Text {
                    anchors.centerIn: parent
                    text: model.euro
                    }
                    }

                    //main.qml
                    import QtQuick 2.3
                    Rectangle {
                    width: 300
                    height: 180

                    ListModel {
                        id: mymodel
                        ListElement {
                            euro: "3"
                        }
                        ListElement {
                            euro: "6"
                        }
                    }
                    
                    Repeater {
                        model: mymodel
                        delegate: TimelineDeviceDetail {}
                    }
                    

                    }
                    @

                    Here TimelineDeviceDetail is able to access the model role(euro).
                    Now can you format your question and requirements according to above example so it will be easier for me to understand?

                      That's a good idea to simplify that. Did you compile the example?

                      I get the following error:

                      @
                      qrc:///TestTimeline.qml:12: ReferenceError: model is not defined

                      }

                      TestTimeline.qml:

                      I made some little changes on your code.

                        I set up a new project just to test this little example and the same here. Any suggestions?

                          I fixed this with JavaScript, probably not this best way but it works for me...

                          TimleineVertical.qml:

                          @
                          Row {
                          id: deviceRow
                          spacing: 20

                                                  Repeater {
                                                      id: deviceRepeater
                                                      model: attributes
                          
                                                      Button {id: deviceImageButton;
                                                          anchors.verticalCenter: parent.verticalCenter;
                                                          iconSource: deviceImage;
                                                          width: 100;
                                                          height: 100;
                                                          onClicked: setVisibleDetail(detailRectangle, deviceItem), setTest(euro, kwh, time, euroText, kwhText, timeText)
                          
                                                          style: TimelineDeviceButtonStyle{} }
                          
                                                  }
                          

                          @

                          JavaScript to set the values from the model for the text element:

                          @
                          function setTest(euro, kwh, time, euroText, kwhText, timeText) {
                          euroText.text = euro;
                          kwhText.text = kwh;
                          timeText.text = time;
                          }
                          @

                          Text element:

                          @
                          Text {
                          id: euroText
                          anchors.top: parent.top
                          anchors.topMargin: 30
                          anchors.left: parent.left
                          anchors.leftMargin: 20
                          font.pixelSize: 12
                          }
                          @
