java synth实例

 今天给大家做了个button的synth实例。

   首先要创建一个java文件，定义一个button的类，并且在类里面初始化button。画出来

代码如下：

import java.awt.Dimension;
import java.awt.FlowLayout;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.UIManager;
import javax.swing.plaf.synth.SynthLookAndFeel;

public class MyButton {
JFrame frame = new JFrame("Test synth");
JButton btn = new JButton("Sure");

public MyButton(){
 frame.setLayout(new FlowLayout());
 frame.setPreferredSize(new Dimension(300, 300));
 frame.setBounds(400, 400, 0, 0);
 btn.setPreferredSize(new Dimension(100,100));
 frame.getContentPane().add(btn);
}

public void show(){
 frame.pack();
 frame.show();
}

}

其次呢，就是把button和它的样式文件xml文件绑定起来，这个要在main函数中做处理；代码如下：

public static void main(String[] args){

 SynthLookAndFeel slf = new SynthLookAndFeel();
 try {
 slf.load(MyButton.class.getResourceAsStream("mybutton.xml"), MyButton.class);
 UIManager.setLookAndFeel(slf);
 } catch (Exception e) {
 e.printStackTrace();
 return;
 }
 MyButton mBtn = new MyButton();
 mBtn.show();

}

再次呢，就是创作样式xml文件，代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<synth>
<style id="mybutton">
  <state>
     <imagePainter method="buttonBackground" path="images/001.png"
        sourceInsets="9 10 9 12" paintCenter="true" stretch="true"/>
     <insets top="9" left="10" bottom="9" right="12"/>
     <font name="Aharoni" size="16"/>
     <color type="TEXT_FOREGROUND" value="#FFFFFF"/>
  </state>
  <state value="MOUSE_OVER">
     <imagePainter method="buttonBackground" path="images/002.png"
        sourceInsets="9 10 9 12" paintCenter="true" stretch="true"/>
     <insets top="9" left="10" bottom="9" right="12"/>
     <color type="TEXT_FOREGROUND" value="#FFFFFF"/>
  </state>
  <state value="PRESSED">
     <imagePainter method="buttonBackground" path="images/003.png"
        sourceInsets="10 12 8 9" paintCenter="true" stretch="true"/>
     <insets top="10" left="12" bottom="8" right="9"/>
     <color type="TEXT_FOREGROUND" value="#FFFFFF"/>
  </state>
  <property key="Button.margin" type="insets" value="0 0 0 0"/>
</style>
<bind style="mybutton" type="region" key="Button"/>
</synth>
这样，运行下看下效果，是不是就已经知道了synth做控件皮肤的强大了？其他控件是相同的做法！
