我有一个需要扩展一点的视图组件的窗扇。

该视图列出了帐户。

这个想法是在组件顶部显示一个小通知，表明正在同时查看某个帐户。适当的侦听器和方法已准备就绪，但我没有 GUI 技能...

任何人都可以帮助我并提出一种方法吗？

应该在事物的顶部显示一个红色的小句子“当前正在查看帐户 1、2”...

用什么？CoolBar? 状态栏？它是如何使用的？我没有找到很好的例子......

您可以使用 SWT 标签来显示该信息。这是一个向您展示如何使用它的 SWT 片段。这就是它的来源：http: //www.eclipse.org/swt/snippets/。这应该可以帮助您开始使用 SWT 和 JFace 构建 GUI。
