== Four new AWT modality models introduced with the Java Mustang release. ==

Modal TypeDescriptionMode-lessDoes not block any other window while it"s rendered on the user display.Document-modalBlocks all windows from the same document with the exception of those windows from its child hierarchy.Application-modalBlocks all windows from the same application with the exception of those windows from its child hierarchy.Toolkit-modalBlocks all windows from the same toolkit with the exception of those toolkits from its child hierarchy.

== Improved Dialog 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:
<OL><LI>APPLICATION_MODAL. Blocks all windows in the same application except those with the modal dialog as their owner.</LI><LI>DOCUMENT_MODAL. Makes all windows from the same document inaccessible, except those from the modal dialog"s child hierarchy.</LI><LI>MODELESS. Does not block any other windows.</LI><LI>TOOLKIT_MODAL. Makes all windows from the same toolkit inaccessible, except those from the modal dialog"s child hierarchy.</LI></OL>
