TableViewer 中的表行是否有悬停事件
我有一个 JFace 表查看器，它由大量行组成，我认为如果每行都有一个简短的描述会更好，作为一种解决方法，我试图实现双击监听器，但这不适合我的需要，我不知道是否有像悬停这样的事件，它显示一个工具提示，其中包含有关特定行的简要信息。
i have a JFace table-viewer, which consists of large number of rows, i thought that it would be better if there is a short description for each row,as a workaround i was trying to implement doubleclick listner but that's not apt to my need,i don't know if there is an event like hover for this,which shows a tooltip containing a brief info about the particular row.

event.item.getData()，而这是在最后一个选项中提供给您的...The answer to this question depends somewhat on the exact implementation of your table viewer. Having said that, the primary options are:

event.item.getData(), whereas that is provide to you in the last option...
