Hi,
You should be able to use the Connections element to respond to signals emitted
by a Loader's item:
//main.qml
Rectangle{
id: root
width: 860
height: 540
Loader { id: loader1; source: "A.qml" }
Loader { id: loader2; source: "B.qml" }
Connections {
target: loader1.item
onAnimationFinished: pickNext()
}
function pickNext()
{
// pick nect
}
}
Regards,
Michael
