    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
              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

                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

                                        Repeater {
                                            id: deviceRepeater
                                            model: timeslotmodel
                                            delegate: detailRectangle

                  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
                            anchors.left: parent.left
                            anchors.leftMargin: 20
                            font.pixelSize: 12
                            }
                            @
