Converter clients can supply a converter observer object +by implementing the MConverterUiObserver interface. The object +is passed to the converter's CConverterBase2::ConvertL(), CConverterBase2::ConvertObjectL(), CConverterBase2::ConvertAL() or CConverterBase2::ConvertObjectAL() function. It is used +for reporting on the progress of multi-step conversions and for requesting +a password from the client when the file being converted from is password-protected.

The +following functions can be implemented:

    +
  • virtual void MaxSteps(TInt aMax, TInt aObject)=0; to +get the maximum number of steps that the conversion operation can take.

  • +
  • virtual TInt Result(TInt aResult, TInt aObject)=0; to +take some action following an error in the conversion.

  • +
  • virtual HBufC* QueryPasswordL(const TDesC& aClue)=0; to +request a password from the user in order to access the data.
