What are the valid keys in CodeNameOne List Component's ListItems? CodeNameOne列表组件的ListItems中的有效键是什么？

In the CodeNameOne GUI builder, you can set keys for each item in a list. 在CodeNameOne GUI构建器中，可以为列表中的每个项目设置键。 The default behavior is that certain keys will cause additional behaviors, like showing icons or navigation. 默认行为是某些键会导致其他行为，例如显示图标或导航。 However, I can't seem to find any documentation for what the recognized keys are. 但是，我似乎找不到任何有关可识别键的文档。

I know of $navigation, destination, and icon, but are there anymore keys that the default renderer and controller can use? 我知道$ navigation，destination和icon，但是是否还有默认渲染器和控制器可以使用的键？

If you use the MultiList then you can determine the "name" of the elements on the MultiList which will map directly to the keys in the entry. 如果使用MultiList则可以确定MultiList上元素的“名称”，这些元素将直接映射到条目中的键。 If you use a List then the renderer will use the names of the components within the renderer container as the values for the keys. 如果使用列表，则渲染器将使用渲染器容器中组件的名称作为键的值。 I suggest reading deeper in the renderer where I discuss some interesting special cases and edge cases. 我建议深入阅读渲染器，在其中讨论一些有趣的特殊情况和边缘情况。
