JTree problem on MAC

Hi,

I am adding a Panel as a JTree node .

It is working fine on windows and linux.

But it shows only small portion on MAc.

I have tried everything like using gridBagConstraints.

But still the problem persists on mac.Is it a java bug.

Can anyone please help me to sort out this problem.

I am posting two classes which will illustrate the problem

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JApplet;

import javax.swing.JButton;

publicclass app

extends JApplet

implements ActionListener

{

publicvoid init()

{

// TODO Auto-generated method stub

JButton app =new JButton();

app.setText("Click");

app.addActionListener(this);

this.getContentPane().add(app);

}

publicvoid actionPerformed(ActionEvent e)

{

if (e.getActionCommand().equals("Click"))

{

TestTree tt =new TestTree();

tt.init();

tt.setVisible(true);

}

}

}

the second class

import java.awt.BorderLayout;

import java.awt.Color;

import java.awt.Component;

import java.awt.Dimension;

import java.awt.FlowLayout;

publicclass TestTree

extends JDialog

{

JTree tree;

DefaultTreeModel treeModel;

public TestTree()

{

setTitle("Pandharinath");

setSize(450, 450);

}

publicvoid init()

{

DefaultMutableTreeNode subroot1 =new DefaultMutableTreeNode("Windows");
