- // File: ComApplication.c
- //
- // Contains: Application-specific code for basic VR movie display and control.
- // This file is used for BOTH MacOS and Windows.
- //
- // Written by: Tim Monroe
- // Based (heavily!) on the MovieShell code written by Apple DTS.

- // Change History (most recent first):
- //
- // <10> 10/23/97 rtm moved InitializeQTVR to InitApplication, TerminateQTVR to StopApplication
- // <9> 10/13/97 rtm reworked HandleApplicationMenu to use menu identifiers
- // <8> 09/11/97 rtm merged MacApplication.c and WinApplication.c into ComApplication.c
- // <7> 08/21/97 rtm first file for Windows; based on MacApplication.c for Mac sample code
- // <6> 06/04/97 rtm removed call to QTVRUtils_IsQTVRMovie in InitApplicationWindowObject
- // <5> 02/06/97 rtm fixed window resizing code
- // <4> 12/05/96 rtm added hooks into MacFramework.c: StopApplication, InitApplicationWindowObject
- // <3> 12/02/96 rtm added cursor updating to DoIdle
- // <2> 11/27/96 rtm conversion to personal coding style; added preliminary QTVR support
- // <1> 12/21/94 khs first file
- //

- // VRShell is a simple QuickTime VR viewer framework. It demonstrates how to incorporate
- // QuickTime and QuickTime VR movies into an application. VRShell is based heavily on the
- // MovieShell QuickTime playback framework included with the DTS QT sample code.
