チャット パネルを作成して Jframe に追加しましたが、パネルが表示されません。しかし、チャット パネルの私の SOP はコンソールに表示されています。誰でも何が問題なのか教えてください
マイフレーム
public class MyFrame extends JFrame {
MyPanel chatClient;
String input;
public MyFrame() {
input = (String)JOptionPane.showInputDialog(null, "Name:", "Connect to chat
server", JOptionPane.QUESTION_MESSAGE, null,null, "Test");
input=input.trim();
chatClient = new MyPanel("localhost",input);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
add(chatClient);
}
public static void main(String...args){
new MyFrame();
}
}
マイパネル:
public class MyPanel extends JPanel{
ChatClient chatClient;
public MyPanel(String host, String uid) {
chatClient= new ChatClient(host,uid);
add(chatClient.getChatPanel());
this.setVisible(true);
}
}
チャットパネル:
public class ChatClient {
Client client;
String name;
ChatPanel chatPanel;
String hostid;
public ChatClient(String host,String uid){
client = new Client();
client.start();
System.out.println("in constructor");
Network.register(client);
client.addListener(new Listener(){
public void connected(Connection connection){
System.out.println("in client connected method");
Network.RegisterName registerName = new Network.RegisterName();
registerName.name=name;
client.sendTCP(registerName);
}
public void received(Connection connection,Object object){
System.out.println("in client received method");
if (object instanceof Network.UpdateNames) {
Network.UpdateNames updateNames = (Network.UpdateNames)object;
//chatFrame.setNames(updateNames.names);
System.out.println("got it message");
return;
}
if (object instanceof Network.ChatMessage) {
Network.ChatMessage chatMessage = (Network.ChatMessage)object;
//chatFrame.addMessage(chatMessage.text);
System.out.println("send it message");
return;
}
}
}); // end of listner
name=uid.trim();
hostid=host.trim();
chatPanel = new ChatPanel(hostid,name);
chatPanel.setSendListener(new Runnable(){
public void run(){
Network.ChatMessage chatMessage = new Network.ChatMessage();
chatMessage.chatMessage=chatPanel.getSendText();
client.sendTCP(chatMessage);
}
});
new Thread("connect"){
public void run(){
try{
client.connect(5000, hostid,Network.port);
}catch(IOException e){
e.printStackTrace();
}
}
}.start();
