Java學習筆記之用Box布局swing介面

主要就用到了這四個方法

createHorizontalBox()

          建立一個從左至右顯示其組件的 Box。

createHorizontalStrut(int width)              //左右組件之間的中間間隔就可以用這個方法來控制
          建立一個不可見的、固定寬度的組件。

createVerticalBox()

          建立一個從上到下顯示其組件的 Box。

createVerticalStrut(int height)            //上下組件之間的中間間隔就可以用這個方法來控制
          建立一個不可見的、固定高度的組件。

如下
