熱度圖 - 可編輯還是不可編輯？一個人如何開始上課？

Question

我正在開發一個項目，在那裏我打算在JAVA中創建一個類，使用它我可以創建一個圖。詳細地說，我想創建2個接口 - VERTEX和EDGE，每個接口都有addVertex（），addEdge（），neighborVertex（），numOfNeighbors（）等方法，以及我的類（稱爲Graph）將實現上述接口。 我現在是JAVA的新手，想知道如何繼續使用ZEST？另外，如果我使用ZEST，圖表是否可編輯？

期待快速回復。謝謝！

* Lars Vogel的教程幫助了我，但我仍然無法使它工作。請幫我敲下列錯誤！現在已經嘗試了相當長的一段時間，弄清楚什麼是錯誤的，但我一定會感謝你的幫助。 *

可能有人建議我現在該怎麼辦？幫助將真正被讚賞。

Answer 1

如果要用Zest將圖形可視化，則必須將自己的圖形對象轉換爲Zest圖形，或者首先使用Zest對象。看看Eclipse wiki和this tutorial中的一些樣本。

該圖不能用Zest編輯（重點在於可視化），但是基於SWT，您可以使圖形交互（將偵聽器添加到節點等）。如果你想要編輯圖形，可以看看Graphiti或者JUNG。
