-fx-effect: dropshadow(three-pass-box, rgba(0,0,0,0.4), 10, 0, 0, 0);请解释这段代码的含义

这段代码是给一个元素添加一个阴影效果。具体解释如下：
- `fx-effect` 是 JavaFX 中的一个 CSS 属性，表示给元素添加一个视觉效果。
- `dropshadow` 是 `fx-effect` 的一个子属性，表示添加一个阴影效果。
- `three-pass-box` 是 `dropshadow` 的一个参数，表示阴影的模糊程度，值为 3 表示模糊程度较高。
- `rgba(0,0,0,0.4)` 是 `dropshadow` 的另一个参数，表示阴影的颜色和透明度，这里的颜色是黑色，透明度为 0.4。
- `10, 0, 0, 0` 是 `dropshadow` 的最后一个参数，表示阴影的偏移量，分别对应 x 轴、y 轴和 z 轴方向的偏移量，这里表示阴影在 x 轴方向偏移 10 像素，其他方向不偏移。

qml DropShadow

qml中的DropShadow是一个阴影效果，可以应用于任何QML元素。它可以通过设置属性来调整阴影的颜色、模糊半径、偏移量等。下面是一个简单的例子：

Rectangle {
    width: 100
    height: 100
    color: "red"
    DropShadow {
        anchors.fill: parent
        color: "black"
        radius: 10
        samples: 16
        horizontalOffset: 5
        verticalOffset: 5
    }
}

在这个例子中，我们创建了一个红色的矩形，并在其上应用了一个黑色的阴影。阴影的模糊半径为10，采样数为16，水平和垂直偏移量分别为5。
