Java JFrame视图

绝地灬酷狼 2022-04-13 11:49 232阅读 0赞

这是我用java+可视化工具(Eclipse)写的，具体底层不再解释，代码直接演示使用方法

将此段代码放置在main中

JFrame jframe = new JFrame("MD5加密工具");//里面是名字
    jframe.getContentPane().add(new JavaMD5());//添加视图
    jframe.setSize(460, 450);// 窗口大小
    jframe.setResizable(false);//设置为不可调整大小
    jframe.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);//设置关闭方式
    jframe.setVisible(true);//设置为显示

下面是一些视图

public class JavaMD5 extends JPanel {
    	/**
    	 * 
    	 */
    	private static final long serialVersionUID = 1L;
    	private JTextField textField;
    	private static TextArea textArea;
    	private static JComboBox comboBox;
    
    	/**
    	 * Create the panel.
    	 */
    	public JavaMD5() {
    		setBackground(UIManager.getColor("CheckBox.light"));
    		setLayout(null);
    
    		JLabel lblMd = new JLabel("MD5\u52A0\u5BC6\u5DE5\u5177");
    		lblMd.setForeground(new Color(0, 0, 0));
    		lblMd.setFont(new Font("微软雅黑", Font.PLAIN, 14));
