QML 动画可见属性更改 [英] QML animations visible property changes

问题描述

我希望在元素变得可见时绘制动画(应该是平滑的，而不是整体)

I want an animation to be painted when an element becomes visible (is should appear smoothly, not the whole at all)

我试过了

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 仍然会立即出现

But the selectIconRow still appears immediately

如何使用这样的动画?

推荐答案

因为它是布尔值，所以 visible 属性不能动画.也许 opacity 可以解决问题.

Because it's boolean, visible property cannot be animated. Perhaps opacity could do the trick.
