Ⅱ Java Swing 怎麼自定義界面背景圖片

在java swing中需要為容器添加自定義圖片或者背景圖片。提兄大供兩種簡單的解棗塵氏決方案，一種利用JPanel，另一種利用JLabel，代碼如下：

1、JPanel（源代碼）

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添加背景圖片

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("測試背景圖片");
jframe.add(GImage);
jframe.pack();
jframe.setVisible(true);
jframe.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

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

}

}

2、JLabel源代碼

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

/**利用JLabel來構建圖片*/
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();
}
}

添加控制項：

jlpic.setIcon(icon);
Containerc=newContainer();
JLabeluser=newJLabel("用戶：");
JLabelpassword=newJLabel("密碼：");
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自定義控制項實現扁平化 源代碼（其他語言的源碼也行）

這個不是通過設置一個參數能做到的，目前還只有 Look and Feel 庫代碼提供的定製。JRE 目前自帶了幾種 Look and Feel 庫，你想得到一個扁平化的 UI 外觀，需要外掛一個自己的 Look and Feel 實現。

你可以在每個 Swing 組件的 getUI 方法返回的值中找到它的 UI 類，而具體運行的時候這個 UI 類是什麼則是由 Look and Feel 來自動配置的，比如在 Windows 上可能是 Windows 開頭的類名，而在 Linux 可能是 Metal 開頭的類名。
