Class DeterminateProgressMonitor

java.lang.Object
oracle.javatools.dialogs.progress.DeterminateProgressMonitor

public class DeterminateProgressMonitor

extends java.lang.Object

A progress monitor implementation for determinate progress feedback.

This class is based on Swing's ProgressMonitor, but the implementation conforms to user interface specifications and offers the following additional features:

• a configurable title for the progress dialog.
• optional visibility of the progress bar in the dialog.
• an optionally cancellable dialog.
• a section of the dialog for logging the details of actions.

By default, the progress monitor will not use a delay before making the dialog visible. Recommended settings for the popup decision and delay are 500 and 2000 milliseconds respectively. Thread advice - instances of this class should be configured and their methods invoked from a consumer worker thread and not the AWT event dispatcher thread, which must be left free to process events.
