Package org.eclipse.jface.operation

Provides JFace support for long-running operations.

Package Specification

Long-running operations must be dealt with specially in order to keep the UI helpful and responsive. Typically this involves temporarily disabling most controls and displaying a busy cursor and progress indicator; while the operation is in progress, the only requests that will be accepted will be ones to cancel the operation.

The IRunnableWithProgress interface should be implemented by any class whose instances are intended to be executed as long-running operations. These objects can then be run in any runnable context (IRunnableContext), including such standard JFace UI components as application windows (ApplicationWindow), wizard dialogs (WizardDialog), and progress monitor dialogs (ProgressMonitorDialog). The utility class ModalContext defines the basic mechanism and UI event loop for modal operations.
