qt - QML 动画可见属性更改

Question

我希望在元素变得可见时绘制动画(应该平滑显示，而不是整个)

我试过这个

states: State
{
    name: "iconOff"
    when: iconOnSwitch.checked == false
    PropertyChanges { target: selectIconRow; visible: false }
}

transitions: Transition
{
    reversible: true
    from: ""
    to: "iconOff"
    PropertyAnimation
    {
        properties: "x,y,visible"
        easing.type: Easing.InOutQuad
        from: selectIconRow
        property: "visible"
    }
}

但是 selectIconRow 仍然立即出现

我怎样才能使用这样的动画？

Answer 1

因为它是 bool 值，visible属性不能动画。也许opacity可以做到这一点。
