在SWT中显示“状态”JFace Eclipse - 复合

Question

我有一个窗口的组件需要扩展一点。

该视图列出了帐户。

这个想法是在组件的顶部显示一个小通知，同时查看某个账户。适当的听众和方法已经准备就绪，但我没有GUI技能...

有人能帮助我，并建议一种方法做到这一点？

一个红色的小句子说“账号1，2，目前看”应显示上的东西顶部...

使用什么？ CoolBar？状态栏？以及它如何使用？我没有找到太好的例子...

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