Change property of all items in a Repeater at once?

[ggwolf]

I want blanket commands that modify a property of every item of the repeater. right now I have this javascript function that does the job:

@ function disable() {
for (var i = 0; i < theRepeater.model; i++) {
theRepeater.itemAt(i).state = "disabled"
}
}@

But I am hoping for a single command that can change the state of every item in the repeater to disabled

Hi,

Create a property variable , and then bind that property to the state of the Item and then when you change that property variable the state of each item changes as well

Could you provide an example? I'm not sure what you mean by a property that is bound to the state... isnt that what the state property is for? and where should i be creating this property variable?

Sure here it is,
@
Item {
width: 400
height: 200

property string currentState: ""

Repeater {
    id: repeater
    model: 5
    Rectangle {
        id: rect
        x: index * 50
        y: 0
        width: 50
        height: 50
        color: '#'+Math.floor(Math.random()*16777215).toString(16)
        state: currentState

        states: State {
            name: "moved";
            PropertyChanges { target: rect; y: 50 }
        }

        transitions: Transition {
            NumberAnimation { properties: "y"; easing.type: Easing.InOutQuad }
        }

    }
}

Button {
    text: "Click"
    y: 200-50
    width: 80
    height: 50
    onClicked: { currentState="moved" }
}

}
@

Now here the property variable currentState is binded to state property of each Rectangle. And on click of button we assign a new value to the property currentState and thus on that change the state of each Rectangle gets affected too.
Hope this is what you expect ...

This is an interesting example of QML usage, thanks. I can't use currently because each rectangle's state gets overridden and becomes individual so I have to go back through each one and reset it somehow. I want each item in the repeater to be independent, except in this one case.
