Improved Dialog Modality : Modality « Swing « Java Tutorial

Mustang introduces different types of modality, in which you no longer use setModal but the new method setModalityType in the Dialog class to make a dialog modal.

Dialog.ModalityType is an enum in the java.awt package.

Its values are as follows:

  1. APPLICATION_MODAL. Blocks all windows in the same application except those with the modal dialog as their owner.
  2. DOCUMENT_MODAL. Makes all windows from the same document inaccessible, except those from the modal dialog's child hierarchy.
  3. MODELESS. Does not block any other windows.
  4. TOOLKIT_MODAL. Makes all windows from the same toolkit inaccessible, except those from the modal dialog's child hierarchy.
