property OnProgress: TRVProgressEvent;

(introduced in v1.9)

First, it is called with parameter Stage=rvpstgStarting.

Next, it is called several times with parameter Stage=rvpstgRunning, with PercentDone in range 0..100.

Finally, it is called with parameter Stage=rvpstgEnding.

This event occurs when loading large RTF files/streams, Operation=rvloLoading.

In future, it will be called also during other long operations.

The component does not call this event with Operation=rvloConverting, you can use this value to call this event yourself from your handler of TRVOfficeConverter.OnConverting event.

Note: TRVLongOperation and TRVProgressStage types are declared in RVStyle unit.
