Ⅱ Java Swing 怎么自定义界面背景图片

在java swing中需要为容器添加自定义图片或者背景图片。提兄大供两种简单的解枣尘氏决方案，一种利用JPanel，另一种利用JLabel，代码如下：

1、JPanel（源代码）

packageoo;
importjava.awt.Graphics;
importjava.awt.Image;
importjava.io.File;
importjavax.swing.ImageIcon;
importjavax.swing.JFrame;
importjavax.swing.JPanel;

publicclassDrawing{

JFramejframe=newJFrame();
publicstaticJPanelGImage=null;

publicDrawing(){
initFrame();
}

//初始化窗口
publicvoidinitFrame(){
//利用JPanel添加背景图片

GImage=newJPanel(){

protectedvoidpaintComponent(Graphicsg){
ImageIconicon=newImageIcon("image\benbenla.jpg");
Imageimg=icon.getImage();
g.drawImage(img,0,0,icon.getIconWidth(),
icon.getIconHeight(),icon.getImageObserver());
jframe.setSize(icon.getIconWidth(),icon.getIconHeight());

}

};
jframe.setTitle("测试背景图片");
jframe.add(GImage);
jframe.pack();
jframe.setVisible(true);
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

publicstaticvoidmain(String[]args){
newDrawing();

}

}

2、JLabel源代码

packageswing.draw;
importjava.awt.Image;
importjavax.swing.ImageIcon;
importjavax.swing.JFrame;
importjavax.swing.JLabel;

/**利用JLabel来构建图片*/
publicclassDrawing2{
JLabeljlpic=newJLabel();
JFramejframe=newJFrame();

publicDrawing2(){

init1Frame();
}

publicvoidinit1Frame(){
ImageIconicon=newImageIcon("image\benbenla.jpg");
凳散icon.setImage(icon.getImage().getScaledInstance(icon.getIconWidth(),
icon.getIconHeight(),Image.SCALE_DEFAULT));
System.out.println(icon.getIconHeight()+""+icon.getIconWidth());
jlpic.setBounds(0,0,1366,768);
jlpic.setHorizontalAlignment(0);
jlpic.setIcon(icon);
jframe.setSize(1366,768);
jframe.add(jlpic);
jframe.pack();
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
jframe.setVisible(true);

}

publicstaticvoidmain(Stringargs[]){

newDrawing2();
}
}

添加控件：

jlpic.setIcon(icon);
Containerc=newContainer();
JLabeluser=newJLabel("用户：");
JLabelpassword=newJLabel("密码：");
JTextFieldtxf_userName=newJTextField();
JPasswordFieldpwd_password=newJPasswordField()
{
publicvoidpaste(){
UIManager.getLookAndFeel().provideErrorFeedback(this);
}
};
user.setBounds(200,25,50,25);
password.setBounds(200,52,50,25);
txf_userName.setBounds(300,25,150,25);
pwd_password.setBounds(300,52,150,25);
c.add(user);
c.add(txf_userName);
c.add(password);
c.add(pwd_password);
c.add(jlpic);
jframe.setSize(1366,768);
//jframe.add();
jframe.add(c);

Ⅲ swing自定义控件实现扁平化 源代码（其他语言的源码也行）

这个不是通过设置一个参数能做到的，目前还只有 Look and Feel 库代码提供的定制。JRE 目前自带了几种 Look and Feel 库，你想得到一个扁平化的 UI 外观，需要外挂一个自己的 Look and Feel 实现。

你可以在每个 Swing 组件的 getUI 方法返回的值中找到它的 UI 类，而具体运行的时候这个 UI 类是什么则是由 Look and Feel 来自动配置的，比如在 Windows 上可能是 Windows 开头的类名，而在 Linux 可能是 Metal 开头的类名。
