  TProgressEventEx = procedure(Sender: TObject; const ATotPos: Int64; 
                             const ATotSize: Int64) of object;

    Arguments

    Name Description
    Sender Object for the event notification.
    ATotPos Cumulative number of bytes handled in the caller.
    ATotSize Total number of bytes to be processed in the caller.

    Description

    TProgressEventEx is an object procedure which implements an event handler signalled to indicate compression/decompression progress. It is very similar to TProgressEvent, but provides separate values for the cumulative number of bytes handled and the total number of bytes to be processed.

    TProgressEventEx is the type used to implement the OnProgressEx property in TDeCompressor and TUnZipper.
