    就像QtCreator 示例中的ContactList一样
    如果有一个 元素是Text
    而且这个Text的wrapMode 是WordWrap

    那么第一次显示的时候就会出现 QML ItemDelegate: Binding loop detected for property "implicitHeight"
    这种情况应该怎么解决 呢
    尝试过使用lineCount * lineheight 设置固定高度,但是好像 不生效

      自适应高度需要在Delegate做到父控件根据子控件的大小来改变大小。一个有用的属性是
      Item::childrenRect。
      Qt Quick Controls 2里面的控件布置得都挺好的,因为都继承Control这个类。
