[Solved] Receiving signals emitted by Repeater item

stevenhurd

Is there a way to receive a signal from an item created by a Repeater in the QML itself? Consider the following simplified example:

@Rectangle {
…
Repeater {
model: cppModel
delegate: SimpleDelegate{}
}
}

// SimpleDelegate.qml
Item{
…
signal itemSignal(int index)
…
}@

Is there a way to receive itemSignal somewhere where I can then operate on the item and, most likely, all the other items in the repeater as well? So far I haven’t been able to figure out how to handle this scenario without involving the C++ model.

I think you can accomplish that using connect (http://doc.qt.digia.com/qt/qmlevents.html#connecting-signals-to-methods-and-signals).

Here is my guess:

@delegate: SimpleDelegate{
Component.onCompleted: {
itemSignal.connect(someFunction)
}
}@

Certainly. You might want to read up on how to do signal and slot connections with [removed]
http://doc.qt.digia.com/qt/qmlevents.html

The most relevant example is this one:
@
Rectangle {
id: forwarder
width: 100; height: 100

 signal send()
 onSend: console.log("Send clicked")

 MouseArea {
     id: mousearea
     anchors.fill: parent
     onClicked: console.log("MouseArea clicked")
 }
 Component.onCompleted: {
     mousearea.clicked.connect(send)
 }

}

Just connect your itemSignal to a function in the SimpleDelegate::onCompleted handler. (or alternatively in the Repeater::onItemAdded handler)

Yes, thank you! I was under the mistaken impression that I needed Connections items to implement signals and slots in QML. This solution works perfectly.
