Extending the QTKitPlayer Application
[[mMovieView window] setFrame:NSMakeRect(topLeft.x, topLeft.y -
newWindowBounds.size.height, newWindowBounds.size.width,
newWindowBounds.size.height) display:YES];
}
nowSizing = NO;
9. To deal with NSDocument overrides, add these lines:
- (NSString *)windowNibName
{
return @"MovieDocument";
}
10. To set up the movie view and set the editable state of the controller, you need to add this chunk
of code. You also want to “listen” for any movie size changes, so notifications are added here.
Insert the following:
- (void)windowControllerDidLoadNib:(NSWindowController *)windowController
{
// set up the movie view
if (mMovie)
{
NSSize contentSize = [[mMovie attributeForKey:QTMovieNaturalSizeAttribute]
sizeValue];
[mMovieView setMovie:mMovie];
if ([mMovieView isControllerVisible])
{
contentSize.height += [mMovieView movieControllerBounds].size.height;
if (contentSize.width == 0)
{
contentSize.width = kDefaultWidthForNonvisualMovies;
}
}
[[mMovieView window] setContentSize:contentSize];
}
else
[mMovieView setMovie:[QTMovie movie]];
// set the editable state
[mMovie setAttribute:[NSNumber numberWithBool:YES]
forKey:QTMovieEditableAttribute];
// watch for movie resizings
if (mMovie)
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(sizeWindowToMovie:) name:QTMovieSizeDidChangeNotification
object:mMovie];
}
11. To write to handle updates and saves, add the following code:
- (BOOL)writeWithBackupToFile:(NSString *)fullDocumentPath ofType:(NSString
*)type saveOperation:(NSSaveOperationType)saveOperation
{
BOOL success = NO;
