I am trying to use the ProgressView / Cell class from the developer sample code to create a progress bar for a QTMovie.

I want to get the status of the movie as a percent from currentTime / Duration but do not understand QTTime. Code:

NSDictionary *myAtts = [theMovie movieAttributes];

NSValue *durationValue = [myAtts objectForKey: QTMovieDurationAttribute];

NSValue *currentValue = [myAtts objectForKey: QTMovieCurrentTimeAttribute];

How do I get a float value from an NSValue?

Thanks, Rich
