Is there a way how to use a dialog in Swing which prohibits any gui activity under it but at the same time DOES NOT stop execution on the thread where it was set to visible?

JDialog(Dialog owner, boolean modal) Creates a dialog box with the specified Dialog owner and modality. JDialog(Dialog owner, String title) Creates a modeless dialog box with the specified Dialog owner and title.
JFrame is a normal window with its normal buttons (optionally) and decorations. JDialog on the other side does not have a maximize and minimize buttons and usually are created with JOptionPane static methods, and are better fit to make them modal (they block other components until they are closed).
If you really want to center a JDialog on screen, you can use code like this: // center a jdialog on screen JDialog d = new JDialog(); d. setSize(400, 300); d. setLocationRelativeTo(null); d.
JDialog is one of the important features of JAVA Swing contributing to interactive desktop-based applications. This is used as a top-level container on which multiple lightweight JAVA swing components can be placed to form a window based application.
Yes it can be done .
dlg.setModal(false);
or
dlg.setModalityType(Dialog.ModalityType.MODELESS);
where dlg is instance of your JDialog .

The basic idea of a JDialog IS to block the underlying thread until the user reacts to it. If you need to run something on the UI thread which should not be interrupted, consider using an additional worker thread for it. This way, the UI will be blocked by the JDialog, but the underlying process won't.
