Repeater::itemAt access to non-Item properties

pawelbial

Hello.

I define Block element and I use it with repeter:
@
Grid {
id: answerGrid
...
Repeater {
id: rep
model: 3
Block {
}
@

When I use itemAt function:

@rep.itemAt(i)@

It return a Item object. And I can't access to variable with I add to Block item.

Is there any simple way to access it?

Hello,

that's strange. I used this and I did not have any problems. (http://developer.qt.nokia.com/wiki/QML_Scrolling_Digits)

Can you show more code or if there are some errors in output?

I create sample project
main.cpp
@import QtQuick 1.1
import "Addons" as Addons

Rectangle {
id: board
(color, width ...)
Grid {
id: answerGrid
(anchors)
columns: 6
rows: 6
spacing: 7

    Repeater {
        id: blocks
        model: 36
        Addons.Block{
            id: block
        }
    }
}

}
@

Addons/block.qml
@
import QtQuick 1.1

Rectangle {
id: block
(width,height...)
Grid {
property int row: Math.floor(index/answerGrid.columns)
property int col: index-row*answerGrid.columns
id: cellGrid
(anchors)
columns: 3
rows: 2
spacing: 2
Repeater {
id :repro
model: 6
Rectangle {
id: cell
(width,height,color)

            Text{
                id: num
                (anchors)
                text: index
            }
            MouseArea{
                id: cellMouse
                anchors.fill: parent
                onClicked: {
                   console.log(blocks.itemAt(0).cellGrid)
                   blocks.itemAt(0).cellGrid.rows = 5
                }
            }
        }
    }
}

}

Conslole.log returns undefined value.
Next line return

Hello,

blocks is id from main.qml and it is not visible in block.qml See "Component scope":http://doc.qt.nokia.com/4.7-snapshot/qdeclarativescope.html#component-scope

Thanks for replay :) Still I don't really undestand what element's are visible and with are not. I was able to access board.width or answerGrid.columns from block.qml with propably shoudn't be possible.

I solved problem with access to the element using itemAt.
When I used @console.log(blocks.itemAt(0).repro)@ it return undefined, but when I add @property alias repro: repro@ to block.qml it return right object.
