QML----StackView动画

废话不多说，直接上代码（这里是渐入溅出）

StackView{
	objectName: "rootStack"
	id:stackView
	initialItem: spalsh
	anchors.fill: parent
	replaceEnter: Transition {
		PropertyAnimation {
			target: stackView
			property: "opacity"
			from: 0
			to: 1
			duration:700
			easing.type: Easing.InOutElastic;
			easing.amplitude: 2.0;
			easing.period: 1.5
		}
	}
	replaceExit: Transition {
		PropertyAnimation {
			target: stackView
			property: "opacity"
			from: 1
			to: 0
			duration:500
			easing.type: Easing.InOutElastic;
			easing.amplitude: 2.0;
			easing.period: 1.5
		}
	}
}

replace动画替换：

注意：

1. Exit动画多于Enter时间会白屏。
2. stackview动画尽量不要用弹性渐入溅出，导致闪屏
3. enter和exit不要有太长的时间间隔。
