// File: WinFramework.c
//
// Contains: Code for the QuickTime sample code framework that is specific to Windows.
// This code handles windows, menus, events, and other low-level things. Put your
// application-specific code into the file ComApplication.c.
//
// Written by: Tim Monroe
// Based on the QTShell code written by Tim Monroe, which in turn was based on the MDIPlayer
// code written by Brian S. Friedkin (Aug 5, 1996). This current version is now very far removed from
// MDIPlayer.
//
// Copyright: © 1999 by Apple Computer, Inc., all rights reserved.
//
// Change History (most recent first):
//
// <7> 04/03/00 rtm reworked QTFrame_CalcWindowMinMaxInfo; disabled movie window maximize button
// in WM_CREATE message processing (implementing this is left as an exercise...)
// <6> 01/14/00 rtm reworked window-drawing code (WM_PAINT message) to support graphics files
// <5> 01/05/00 rtm minor tweaks to QuickTime initialization in WinMain
// <4> 12/26/99 rtm added WM_LBUTTONDOWN processing to QTFrame_MovieWndProc; minor reorganization
// of QTFrame_MovieWndProc so that myMacEvent and myIsHandled are in scope for
// that message
// <3> 12/16/99 rtm made minor change to QTFrame_MovieWndProc so that QTApp_HandleEvent is called
// even if the window has no movie controller
// <2> 11/29/99 rtm modified "Save changes" dialog box to use Macintosh wordings prompted by move
// to Navigation Services
// <1> 11/05/99 rtm first file; based on earlier sample code
