我在列表框上方创建标签作为标题。您可能会认为，每当您的lisbox发生变化时，更改标签是一种皇室痛苦。你是对的 - 这是一个痛苦。第一次设置是一个痛苦，更少的变化。但我没有找到更好的方法。

No. I create labels above the listbox to serve as headers. You might think that it's a royal pain to change labels every time your lisbox changes. You'd be right - it is a pain. It's a pain to set up the first time, much less changes. But I haven't found a better way.
