Button for closing a JDialog

Question

I want to add a button (JButton) at the bottom of a JDialog which should close the JDialog when pressed. The problem is I don\'t know what to write in the ActionListener of

Answer 1

I have done this slightly differently and it serves the purpose. I have several classes. They extend JPanel, serve different purposes and use JDialogs to get users' inputs.

A typical class would contain necessary fields, save and cancel buttons.

public class EnterpriseGUI extends javax.swing.JPanel {...} would look like this:

Class EnterpriseGUI has a private variable jdialog and a method to set jdialog. Also ActionEvent for 'save' button and 'cancel' button.

private JDialog jdialog;
public void setJDialog(JDialog jdialog) {
    this.jdialog = jdialog;
}
private void btnSaveActionPerformed(java.awt.event.ActionEvent evt) {                                        
    // Do your stuff..
    jdialog.dispose();
} 
private void btnCancelActionPerformed(java.awt.event.ActionEvent evt) {                                          
    // Discard your stuff..
    jdialog.dispose();
} 

Finally, I create an instance of EnterpriseGUI from any other class as needed and embed it into JDialog.

Class OtherClass{
private JDialog dialog;
private EnterpriseGUI = new enterprisegui();
    private void button1ActionPerformed(java.awt.event.ActionEvent evt) {                                             
        this.dialog = new JDialog(this, "My dialog", true);
        this.dialog.setResizable(false);
        enterprisegui.setJDialog(dialog);
        this.dialog.getContentPane().add(enterprisegui);
        this.dialog.pack();

        Dimension Size = Toolkit.getDefaultToolkit().getScreenSize();
        this.dialog.setLocation(new Double((Size.getWidth()/2) - 
                (dialog.getWidth()/2)).intValue(), new Double((Size.getHeight()/2) - 
                        (dialog.getHeight()/2)).intValue());
        this.dialog.setVisible(true);

    }  
}
