JTree（右鍵選單，可拖拽）+JTable（可翻頁，列中含有按鈕，隱藏列）
阿新 • • 發佈：2019-01-31
首先來看一下展示介面，JTree的特點有：節點可拖拽，根據輸入生成目錄，右鍵有選單，點選觸發事件等
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
在來看一下程式碼吧，基本程式碼由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WindowBuilder的時候要畫JTree和JTable時要注意，這兩個有幾個共同點，必須放到JScrollPanel中，因為這兩個控制元件的內容長度會發生突然變化，所以要使用JScrollPanel。
