QuickTime 3 For Windows Programmers
| Previous | Chapter Contents | Chapter Top | Roadmap |
Listing 7-1 shows a simple but complete application program illustrating the use of QuickTime on the Windows platform. The program uses the Windows single document interface (SDI) to present a movie on the screen, allowing the user to control its display by manipulating a standard movie controller with the mouse. The program also supports basic operations such as file saving and simple cut-and-paste editing. The code shown here is adapted from one of the sample programs provided as part of the QuickTime 3 Software Development Kit for Windows.
