Swing GUI working not properly

[Jignesh Gohel]

Hello,

I'm making a gui of the kind in which i want to display the textfield's content into the panel below it as soon as the button "ADD" is pressed.But i'm not able to do this .I've tried out all the possibilities i could think but, no results.
What's happening in the code below is that when the frame is getting maximised the contents of the tree are getting displayed.But i need the simultaneous display of the contents in the textfield into the panel below it.SO,if anybody can help me sort out this problem,I'will be thankful to him.

THE CODE IS GIVEN BELOW:

import java.awt.*;
import javax.swing.*;
import java.util.ArrayList;
import java.awt.event.*;
import javax.swing.tree.*;
 
public class ChatAdder
{
ArrayList list;
JTextField txt;
JButton btnAdd;
JTextArea area;
JTree tree;
JFrame fm;
JPanel panel;
JPanel panel2;
 
 
public void gui()
{
 
fm = new JFrame();
fm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
 
 
panel = new JPanel();
panel.setBackground(Color.darkGray);
 
 
txt = new JTextField(15);
 
//area = new JTextArea(10,10);
//area.setEditable(false);
 
btnAdd = new JButton("Add");
btnAdd.addActionListener(new Adder());
 
 
panel.add(txt);
panel.add(btnAdd);
 
fm.getContentPane().add(BorderLayout.NORTH,panel);
 
 
panel2 = new JPanel();
panel2.setBackground(Color.cyan);
 
panel2.setBounds(50,100,150,150);
//panel2.setLayout(new BoxLayout(panel2,BoxLayout.Y_AXIS));
//fm.getContentPane().add(BorderLayout.CENTER,panel2);
 
        //fm.getContentPane().add(panel2);
 
fm.setSize(300,300);
fm.setVisible(true);
 
fm.getContentPane().setLayout(null);
fm.getContentPane().add(panel2);
 
}
 
 
//Inner class
class Adder implements ActionListener
{
public void actionPerformed(ActionEvent ae)
{
list = new ArrayList();
String str = txt.getText();
list.add(str);
 
txt.setText("");
txt.requestFocus();
 
            show();
 
 
}
 
 
}
 
public void show()
{
for(int i=0;i<list.size();i++)
{
String s = (String)list.get(i);
tree(s);
}
 
}
 
public void tree(String str)
{
 
        DefaultMutableTreeNode top = new DefaultMutableTreeNode("List");
 
DefaultMutableTreeNode a1 = new DefaultMutableTreeNode("First");
top.add(a1);
 
DefaultMutableTreeNode a2 = new DefaultMutableTreeNode("Second");
a1.add(a2);
 
tree = new JTree(top);
panel2.add(tree);
 
}
 
public static void main(String[] args)
{
ChatAdder ca = new ChatAdder();
ca.gui();
 
}
 
 
 
 
}

The first problem I see is that you are adding your text from you JTextField to an ArrayList and then as you loop over the collection you create a tree for every single entry in the ArrayList. However, you never do anything with the actual text from the textfield beyond passing it to the tree(String s) method. I don't think you meant to perform this logic.

That aside, if you add panel2.validate(); just below your call to the show() method in your ActionListener, the JTree will show up after you click the Add button.
