JDialog in front of its parent JFrame

Question

I want to create a Java Swing JDialog, which, when it opens, will not be able to access its parent window (the same as when opening the file explorer dialog box in Microsoft Word). Is there any method in the JDialog class that provides this behavior?

Answer 1

use JDialog.setModal (true) before setting the dialog visible

JDialog yourdialog = ...

yourdialog.setModal(true);
...

yourdialog.setVisible(true);

Answer 2

You have two options:

Use static methods in JOptionPane. They will create modal dialogs by default:

Window parentWindow = SwingUtilities.getWindowAncestor(parentPanel);
JOptionPane.showMessageDialog(parentWindow, "Hello, World); // Create modal dialog aligned with parent window.

Create JDialogexplicitly:

Window parentWindow = SwingUtilities.getWindowAncestor(parentPanel);
JDialog dlg = new JDialog(parentWindow, ModalityType.APPLICATION_MODAL);

This is a concept that exists in the GUI infrastructure as a whole, and not just in the Swing framework. In any graphical environment that you use, you can find such functionality by looking for a property modal.
