子类化QGridLayout时出错

Question

我正在尝试将QGridLayout子类化以构建一个小部件，以设置为QDialog的布局。当我尝试做“setLayout（view）;”在View_currentSpec构造函数中，我有一个来自编译器的错误，该错误表示“未为此范围声明视图”。我做错了吗？

<div ng-controller="EventCtrl">

    <div ng-hide="eventComplete">
        <h2>Example that doesn't disappear on button click</h2>
    </div>

    <div ng-hide="eventComplete"> 
        <div>
            <h2>Example</h2>
            <md-button ng-click="eventFinish();">Finish</md-button>
        </div>
    </div>

    <div ng-show="eventComplete">
        <h2>Complete!</h2>
    </div>
</div>
