Hiding Parent Window Onclick

[Ramesh Jothimani]

My Application flow is as follows : I have a button in my main window . On clicking the button , the new window should appear and the current window should hide.

Code of Parent Window :

public class Welcome extends JPanel {
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private final JLabel lblWelcomeTitle = new JLabel("Welcome");
	private final JLabel lblWelcomeContent = new JLabel("To Proceed , Click on Continue");
	private final JButton btnContinue = new JButton("Continue >>");

	/**
	 * Create the panel.
	 */
	public Welcome() 
	{
		setLayout(null);
		lblWelcomeTitle.setFont(new Font("Comic Sans MS", Font.BOLD, 14));
		lblWelcomeTitle.setBounds(40, 11, 222, 14);
		
		add(lblWelcomeTitle);
		lblWelcomeContent.setBounds(40, 86, 315, 14);
		
		add(lblWelcomeContent);
		btnContinue.addActionListener(new ActionListener() {
			public void actionPerformed(ActionEvent arg0) 
			{
				//frameObj.setVisible(false);
				Welcome.this.setVisible(false);
				JFrame frameObj=new JFrame("Welcome to SHKFI Installation Wizard");
				frameObj.getContentPane().add(new DirectoryPick());
				frameObj.pack();
				frameObj.setSize(390, 240);
				frameObj.setVisible(true);
				frameObj.setResizable(false);
			}
		});
		btnContinue.addMouseListener(new MouseAdapter() {
			
			
		});
		btnContinue.setBounds(257, 157, 109, 23);
		
		add(btnContinue);

	}
	
	public static void main(String args[])
	{
		JFrame frameObj=new JFrame("Welcome");
		frameObj.getContentPane().add(new Welcome());
		frameObj.pack();
		frameObj.setSize(390, 240);
		frameObj.setVisible(true);
		frameObj.setResizable(false);
	}
}

Child Window :

public class DirectoryPick extends JPanel {
	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private final JLabel lblFolderPick = new JLabel("Directory Pick");
	private final JLabel lblDirectoryBrowse = new JLabel("Pick the Installation Source Directory");
	private final JTextField textField_dirpath = new JTextField();
	private final JButton btnBrowse = new JButton("Browse...");

	/**
	 * Create the panel.
	 */
	public DirectoryPick() {
		textField_dirpath.setFont(new Font("Comic Sans MS", Font.BOLD, 12));
		textField_dirpath.setBounds(47, 123, 160, 20);
		textField_dirpath.setColumns(10);
		setLayout(null);
		lblFolderPick.setFont(new Font("Comic Sans MS", Font.BOLD, 14));
		lblFolderPick.setBounds(149, 11, 159, 14);
		
		add(lblFolderPick);
		lblDirectoryBrowse.setFont(new Font("Comic Sans MS", Font.BOLD, 14));
		lblDirectoryBrowse.setBounds(47, 84, 273, 14);
		
		add(lblDirectoryBrowse);
		
		add(textField_dirpath);
		btnBrowse.addActionListener(new ActionListener() {
			/*Click of browse button*/
			public void actionPerformed(ActionEvent e) 
			{
				JFileChooser jf=new JFileChooser();
				int returnValue = jf.showOpenDialog(null);
				jf.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
				if (returnValue == JFileChooser.APPROVE_OPTION) {
		          File selectedFile = jf.getCurrentDirectory();
		          System.out.println(selectedFile.getAbsolutePath());
		        }

			}
		});
		btnBrowse.setBounds(217, 123, 91, 23);
		
		add(btnBrowse);

	}
}

I need to call second window on clicking continue button . The Parent window is not getting hided . Both Windows appear. How can I hide my parent window ?

This line of code:

Welcome.this.setVisible(false);

sets the JPanel inside your "parent" window to be not visible. It doesn't affect the "parent" window at all. You need to have a reference to that window and call setVisible(false) on that reference.

set everything up as a CardLayout

It hides my JPanel & a blank screen is there on the back . I am beginner to Java Swing . How can I make reference to that Window and hide it in button click?
