| Provides JFace support for long-running operations. |
| <h2> |
| Package Specification</h2> |
| 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. |
| <p>The <tt>IRunnableWithProgress</tt> 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 (<tt>IRunnableContext</tt>), |
| including such standard JFace UI components as application windows (<tt>ApplicationWindow</tt>), |
| wizard dialogs (<tt>WizardDialog</tt>), and progress monitor dialogs (<tt>ProgressMonitorDialog</tt>). |
| The utility class <tt>ModalContext</tt> defines the basic mechanism and |
| UI event loop for modal operations. |
