    That's strange. Is it for all 3 or just time ?

      Also I see
      @
      TimelineDeviceDetail {
      id: detailRectangle }
      @

      after the Repeater. Remove it. The error could be because of that too. Since it is not is scope of Repeater, it will also attract those errors.

        Yes, for all three. I removed the TimelineDeviceDetail.

        I get no errors but how can I include the TimelineDeviceDetail back to my TimelineVertical after I deleted:

        @
        TimelineDeviceDetail {
        id: detailRectangle }
        @

          I want the TimelineDeviceDetail exactly at the position where I deleted it.

            So you have TimelineDeviceDetail.qml file. You can assign an id there.

              ... 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

                      width: 0
                      height: 200
                      color: "#FFFFFF"
                      radius: 4

                      // Component.onCompleted: console.log("euro: " + timeslotmodel.euro)
                      text: model.euro

                      }

                          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

                          }
                      

                      //...
                      @

                      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

                        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

                          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:

                                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
