Access model in another qml component

morker

I removed the delegate:

@
//...
Repeater {
id: deviceRepeater
model: timeslotmodel

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

                        }
                    }
                }
            }
        }

        TimelineDeviceDetail {
            id: detailRectangle }

//...
@

... and add the model to my TimelineDeviceDetail view:

@
/...
Text {
id: euroText
Component.onCompleted: console.log("euro: " + timeslotmodel.euro)
text: timeslotmodel.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: " + kwh)
        text: timeslotmodel.kwh
        anchors.top: parent.top
        anchors.topMargin: 20
        anchors.horizontalCenter: parent.horizontalCenter
        font.pixelSize: 12
    }

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

Error:

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

p3c0

That was expected as TimelineDeviceDetail wouldn't know which model item to fetch.
Why not assign TimelineDeviceDetail as a delegate to Repeater ?
Did you try
@
text: model.euro
@

as suggested earlier ?

morker

Same code as in my last post and I add

@
delegate: TimelineDeviceDetail {}
@

to my repeater.

I still get the same error

p3c0

and how TimelineDeviceDetail body looks like now ?

}

}
@

p3c0

So here, instead of
@
text: timeslotmodel.euro
@

try
@
text: model.euro
@

morker

I changed it but still same error:

@
qrc:///TimelineDeviceDetail.qml:42:19: Unable to assign [undefined] to QString
@

p3c0

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

p3c0

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.

morker

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 }
@

morker

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

p3c0

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

morker

... 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...

p3c0

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.

Edited

morker

Yes thats correct I have a separate file: TimelineDeviceDetail.qml

p3c0

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

morker

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...

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.
