If you ve completed this chapter and spent some time perusing the code samples available online at www.skylark.ie/qt4.net/Samples, you should feel considerably more confident about tackling real-world QuickTime applications. The judicious use of QuickTime events will ensure that your application performs well in an event-driven environment. Well-thought-out error handling will contribute to a robust application, while comprehensive error reporting will help in tracking down any problems that do arise, whether the source is in your application or in QuickTime itself. Familiarity with the CFObject data container ensures that you will be in a position to use some of the more powerful features of the QuickTime COM objects, with the added bonus of a useful general-purpose container class to add to your bag of tricks.

If you re working with QuickTime content in a production environment or developing software tools for production, the ability to access QuickTime s metadata capabilities can be a major bonus.
