Swing控件可以实现水平翻转-swing 控件

Swing控件可以实现水平翻转，有看到过阿拉伯国家软件的就知道他们的写作习惯是从右到左的形式，SUN公司为了方便不同客户为Swing控件提供两个实现翻转效果的方法applyComponentOrientation(ComponentOrientationorientation)

设置此组件及其包含的所有组件的ComponentOrientation属性。setComponentOrientation(ComponentOrientationo)

设置语言敏感的方向，用于排序此组件内的元素或文本。

下面的代码建议在JDK1.6上面运行，Swing控件布局采用1.6的类

importjava.awt.ComponentOrientation;  
importjava.awt.event.ActionEvent;  
importjava.awt.event.ActionListener;  
 
publicclassNewJFrameextendsjavax.swing.JFrame{  
 
publicNewJFrame(){  
initComponents();  
jButton1.setActionCommand("jbutton1");  
jButton1.addActionListener(newJButton_ActionListener(this));  
jButton2.setActionCommand("jbutton2");  
jButton2.addActionListener(newJButton_ActionListener(this));
