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

如何在JFrame中使用JInternalFrame？

我想创建一个客户端/服务器应用程序.
我知道JInternalFrame应该与JDeskTopPane一起使用,但我想要一个可以在应用程序中移动的聊天窗口(就像在Facebook聊天一样).

最佳答案

以下是您正在寻找的简短工作示例.
码：

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(
        jInternalFrame1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGap(0,304,Short.MAX_VALUE)
    );

    javax.swing.GroupLayout jPanel1Layout = new javax.swing.GroupLayout(jPanel1);
    jPanel1.setLayout(jPanel1Layout);
    jPanel1Layout.setHorizontalGroup(
        jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addComponent(jInternalFrame1)
    );
    jPanel1Layout.setVerticalGroup(
        jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addGroup(jPanel1Layout.createSequentialGroup()
            .addComponent(jInternalFrame1)
            .addContainerGap())
    );

    javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
    getContentPane().setLayout(layout);
    layout.setHorizontalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addComponent(jPanel1,javax.swing.GroupLayout.DEFAULT_SIZE,Short.MAX_VALUE)
    );
    layout.setVerticalGroup(
        layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
        .addComponent(jPanel1,javax.swing.GroupLayout.PREFERRED_SIZE,javax.swing.GroupLayout.PREFERRED_SIZE)
    );

    pack();
}
   public static void main(String args[]) {
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            new NewJFrame().setVisible(true);
        }
    });
 }


private javax.swing.JInternalFrame jInternalFrame1;
private javax.swing.JPanel jPanel1;

}

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).
