Qt / QML:WebEngineView调整高度

我在ListView中有一堆WebEngineViews。例如:

ListView 
{
    model: myModel
    delegate: Component 
    {
        Item 
        {
            WebEngineView 
            {
                id: myWebView
                Component.onCompleted: loadHtml(model.modelData.htmlText, baseURL)
            }
        }
    }
}

加载html后,如何调整项目的高度?有问题的HTML可能包含图像,所以我想在加载所有内容后调整WebEngineView的大小。我怀疑我可以做类似的事情:

ListView 
{
    model: myModel
    delegate: Component 
    {
        Item 
        {
            WebEngineView 
            {
                id: myWebView
                Component.onCompleted: loadHtml(model.modelData.htmlText, baseURL)
                onLoadingChanged: 
                { 
                    if (!loading && loadRequest.status == WebEngineView.LoadSucceededStatus)
                    {
                        height = ???? 
                    }
                }
            }
        }
    }
}

但我不确定应该设置什么高度。

我能够像`onContentsSizeChaged'一样做我想做的事情:

ListView 
{
    model: myModel
    delegate: Component 
    {
        Item 
        {
            WebEngineView 
            {
                id: myWebView
                Component.onCompleted: loadHtml(model.modelData.htmlText, baseURL)

                onContentsSizeChanged:
                {
                    myWebView.height = contentsSize.height;
                }
            }
        }
    }
}
