Overview

Panel to display progress while erasing media.

Discussion

A DREraseProgressPanel object manages a panel that displays and updates erase progress. The erase panel is responsible for begining the erase.

The erase is begun and a progress panel is displayed on screen by calling beginProgressSheetForErase:modalForWindow: if a sheet interface is desired, or beginProgressPanelForErase: for a non-modal panel.

A DREraseProgressPanel sends a eraseProgressPanel:eraseDidFinish: message to it's delegate when the erase completes. This method allows the delegate to take over end-of-erase handling from the erase progress panel to customize error dialogs or user notification.
