How to call JDialog class from JFrame class?

[garnachito]

Hi guys, please I need some help:

At this point I only know how to call another JFrame class like this:

        if(e.getSource()== openSecond){
	secondClass.main(null);   // open my second class
	this.dispose();               // close this one
}

And in the second class happend the same... I call my main JFrame class and I add this.dispose() to close that frame.

Now I'm trying to have only one JFrame as main class and JDialog classes as modules of the JFrame, so, when I call JDialog I want to disable de main JFrame until the JDialog class closes.

I need someone please to help me to point me in the right direction to be able to do this.

Thanks a lot!

Thanks!

I know how to make JDialogs this is mi class file called altaEmprendedor.class

public class altaEmprendedor extends JDialog {

	private final JPanel contentPanel = new JPanel();

	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		try {
			altaEmprendedor dialog = new altaEmprendedor();
			dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
			dialog.setVisible(true);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	/**
	 * Create the dialog.
	 */
	public altaEmprendedor() {
		setBounds(100, 100, 652, 430);
		getContentPane().setLayout(new BorderLayout());
		contentPanel.setLayout(new FlowLayout());
		contentPanel.setBorder(new EmptyBorder(5, 5, 5, 5));
		getContentPane().add(contentPanel, BorderLayout.CENTER);
		{
			JPanel buttonPane = new JPanel();
			buttonPane.setLayout(new FlowLayout(FlowLayout.RIGHT));
			getContentPane().add(buttonPane, BorderLayout.SOUTH);
			{
				JButton okButton = new JButton("OK");
				okButton.setActionCommand("OK");
				buttonPane.add(okButton);
				getRootPane().setDefaultButton(okButton);
			}
			{
				JButton cancelButton = new JButton("Cancel");
				cancelButton.setActionCommand("Cancel");
				buttonPane.add(cancelButton);
			}
		}
	}

}

I'm calling this from a JFrame class called main.class with the commented lines:

public class main extends JFrame implements ActionListener {

	JButton btnNewButton;
	private JPanel contentPane;

	/**
	 * Launch the application.
	 */
	public static void main(String[] args) {
		EventQueue.invokeLater(new Runnable() {
			public void run() {
				try {
					main frame = new main();
					frame.setVisible(true);
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	/**
	 * Create the frame.
	 */
	public main() {
		setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		setBounds(100, 100, 450, 300);
		contentPane = new JPanel();
		contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
		setContentPane(contentPane);
		contentPane.setLayout(null);
		
		btnNewButton = new JButton("Open JDialog");
		btnNewButton.setBounds(149, 125, 134, 23);
		btnNewButton.addActionListener(this);
		contentPane.add(btnNewButton);
	}
	
	public void actionPerformed(ActionEvent e){
		
		if(e.getSource()== btnNewButton){
			altaEmprendedor.main(null);          //I'm calling the JDialog class with this line
		}
		
		
	}
	
}

So when you press a button in the main.class it opens altaEmprendedor.class

Now the problem is that doing this the main.class window is still enabled and I need to disable that window until the user closes the JDialog window

Thanks in advance!

Read post #2...in the tutorials, there is mention of modality which may be of interest to you.
