The current documentation for QML ParallelAnimation doesn't mention this restriction, neither does it mention the concept of an AnimationGroup. That concept doesn't seem to be exposed very explicity in the QML docs. The impression I get from the docs. as they currently stand is that a SequentionAnimation and a ParallelAnimation are fundamentally the same type of Item as, say, a PropertyAnimation.

The following example works as expected however: import Qt 4.7 Item { id: page height: 200 width: 200 Text { id: t1 text: "Colours" font.pointSize: 18 font.bold: true anchors.horizontalCenter: page.horizontalCenter anchors.verticalCenter: page.verticalCenter color: "grey" } ParallelAnimation { running: true ColorAnimation { id: ca property: "color" target: t1 loops: Animation.Infinite from: "red" to: "blue" duration: 4000 } RotationAnimation { id: ra property: "rotation" target: t1 loops: Animation.Infinite from: 0.0 to: 360.0 duration: 4000 } } } -- Stephen Collyer
