java – 使用JInternalFrame在客户端/服务器应用程序中创建聊天

public class NewJFrame extends javax.swing.JFrame {

public NewJFrame() {
    initComponents();
}

@SuppressWarnings("unchecked")
    private void initComponents() {

    jPanel1 = new javax.swing.JPanel();
    jInternalFrame1 = new javax.swing.JInternalFrame();

    setDefaultCloSEOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

    jInternalFrame1.setBackground(new java.awt.Color(0,204));
    jInternalFrame1.setBorder(javax.swing.BorderFactory.createMatteBorder(7,7,new java.awt.Color(0,0)));
    jInternalFrame1.setTitle("This is JInternal Frame");
    jInternalFrame1.setVisible(true);

    javax.swing.GroupLayout jInternalFrame1Layout = new javax.swing.GroupLayout(jInternalFrame1.getContentPane());
    jInternalFrame1.getContentPane().setLayout(jInternalFrame1Layout);
    jInternalFrame1Layout.setHorizontalGroup(
        jInternalFrame1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGap(0,386,Short.MAX_VALUE)
    );
    jInternalFrame1Layout.setVerticalGroup(

P.S – 我已经接受了JPanel的帮助.如果您希望随时隐藏组件,
使用foo.setVisible(false)的setVisible(false).
