在SWT中顯示「狀態」JFace Eclipse - 複合

Question

我有一個窗口的組件需要擴展一點。

該視圖列出了帳戶。

這個想法是在組件的頂部顯示一個小通知，同時查看某個賬戶。適當的聽衆和方法已經準備就緒，但我沒有GUI技能...

有人能幫助我，並建議一種方法做到這一點？

一個紅色的小句子說「賬號1，2，目前看」應顯示上的東西頂部...

使用什麼？ CoolBar？狀態欄？以及它如何使用？我沒有找到太好的例子...

您可以使用SWT標籤來顯示該信息。這是一個SWT片段，向您展示如何使用它。這是它的來源：http://www.eclipse.org/swt/snippets/。這應該可以幫助您開始使用SWT和JFace構建GUI。
