Improved Dialog Modality : Modality « Swing « Java Tutorial

1. Java Tutorial
2. Swing
3. Modality

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.
