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); } }
