public class MessageDialog
extends Dialog

Subclass of Dialog which displays a title & message(s), as well as an "OK" button.

This class was written because AWT does not have an equivalent to JOptionPane.

Like typical Java GUI code, this class's GUI parts (the constructor and all instance methods) are not multithread safe: they expect to only be called by EventQueue's dispatch thread. Note, however, that the chief public API method, display, may be safely called by any thread.

MessageDialog

private MessageDialog(Window owner,
                      String title,
                      Dialog.ModalityType type,
                      String... messages)
               throws IllegalArgumentException
Calls super(owner, title, modal), then adds each message in the array as a separate Label and an "OK" Button on the bottom, then shows this instance.

Throws:
IllegalArgumentException - if messages is null or empty
Method Detail

display

public static void display(Window owner,
                           String title,
                           Dialog.ModalityType type,
                           String... messages)
                    throws InterruptedException,
                           InvocationTargetException
Creates and displays a new MessageDialog instance.

The modal param specifies two different things. First, it controls the modality of the dialog that is displayed.. Second, it determines the execution mode. In particular, if modal is true, then this method executes synchronously (i.e. it blocks until the user has dismissed the dialog). Otherwise, it executes asynchronously (i.e. it returns immediately after displaying the dialog).

This method may be called by any thread because it internally submits all of its work to EventQueue's dispatch thread.

Throws:
InterruptedException - if the calling thread is interrupted will waiting inside this method
InvocationTargetException - if a problem happens while creating and displaying the dialog; this Exception will wrap the underlying Throwable (e.g. an IllegalArgumentException if one of the args of this method is invalid)
