Swing如何显示图片
1）使用JLabel支持html的特性显示图片package test;import javax.swing.JFrame;import javax.swing.JLabel;/** * 使用JLabel支持html显示图片 * @author wasw100 */public class DisplayImageHtml extends JFrame { private JLabel lblImg; public DisplayImageHtml() {setTitle("swing显示图片");setSize(200, 140);setDefaultCloseOperation(DISPOSE_ON_CLOSE);lblImg = new JLabel();add(lblImg);setVisible(true);lblImg.setText("<html><img src='http://www.wasw100.com/wp-content/themes/inove/img/logo.gif' /><html>"); } public static void main(String[] args) {new DisplayImageHtml(); }}2）使用JLabel的setIcon显示图片
package test;import java.net.MalformedURLException;import java.net.URL;import javax.swing.Icon;import javax.swing.ImageIcon;import javax.swing.JFrame;import javax.swing.JLabel;public class DisplayImageIcon extends JFrame { private JLabel lblImg; private Icon icon; public DisplayImageIcon() {setTitle("swing显示图片");setSize(200, 140);setDefaultCloseOperation(DISPOSE_ON_CLOSE);lblImg = new JLabel();add(lblImg);setVisible(true);try { icon = new ImageIcon(new URL("http://www.wasw100.com/wp-content/themes/inove/img/logo.gif"));} catch (MalformedURLException e) { e.printStackTrace();}lblImg.setIcon(icon); } public static void main(String[] args) {new DisplayImageIcon(); }}
