實例 JTree（右鍵菜單，可拖拽）+Jtable（可翻頁，列中含有按鈕，隱藏列）

jopen 11年前發布 | 91K 次閱讀 JTree Swing Java開發
首先來看一下展示界面，JTree的特點有：節點可拖拽，根據輸入生成目錄，右鍵有菜單，點擊觸發事件等
JTable的特點有：含有隱藏列，可以進行翻頁，列中含有下載按鈕等
在來看一下代碼吧，基本代碼由Eclipse上的WindowBuilder進行拖拽式產生的，所以看起來有點亂，不過沒事
在使用WindoerBuilder的時候要畫JTree和JTable，這兩個有幾個共同點，必須放到JScrollPanel中，因為這兩個控件的內容會可能有很多。
