How many types of JDialog boxes can be created in Java?
A JDialog is a subclass of Dialog class and it does not hold minimize and maximize buttons at the top right corner of the window. We can create two types of JDialog boxes.in Java
- Modal Dialog
- Non-Modal Dialog
Modal JDialog
In Java, When a modal dialog window is active, all the user inputs are directed to it and the other parts of the application are inaccessible until this model dialog is closed.
Non-Modal JDialog
In Java, When a non-modal dialog window is active, the other parts of the application are still accessible as normal and inputs can be directed to them, while this non-modal dialog window doesn't need to be closed.
Example
import javax.swing.*;
import java.awt.*;
import java.awt.Dialog.ModalityType;
public class Modal_NonModal_Dialog {
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setTitle("Modal and Non-Modal Dialog");
frame.setSize(350, 300);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
// modal dialog
JDialog nonModalDialog = new JDialog(frame, "Non-Modal Dialog", ModalityType.MODELESS);
nonModalDialog.setSize(300, 250);
nonModalDialog.setLocationRelativeTo(null);
nonModalDialog.setVisible(true);
// non-modal dialog
JDialog modalDialog = new JDialog(frame, "Modal Dialog", ModalityType.APPLICATION_MODAL);
modalDialog.setSize(300, 250);
modalDialog.setLocationRelativeTo(null);
modalDialog.setVisible(true);
}
}Output
