Qml 写的弹出层控件（13篇博客）

QML弹出窗口组件，灯箱效果、动画效果，可拖拽

核心思路：一个mask层，一个最顶层，都用rectangle，禁止事件穿透

使用

    Popup {

        id: popup

        width: 200; height: 300

        x: 200; y:100

        z: 101

        opacity: 0.8

        visible: false;

        radius: 5

        ...

    }

    popup.showMask = chk.checked;

    popup.animationType = 'size';

    popup.show();

注意

    使用位移动画不能用anchors定位方式

万能的qml，编起UI好开心。
再也不用管div、css、box原型、相对定位、绝对定位、浏览器适配、低性能的canvas...坑爹的html+js，无穷尽的js框架，这么多年了，怎么都摞不顺，永远扶不直的阿斗。

自从用了qml，整个人心情都舒畅了，腰也直了，背也不弯了，考试天天考100分
