11. To set the current size text field, add:
- (void)setCurrentSizeDisplay
{
NSSize movCurrentSize = NSMakeSize(0,0);
movCurrentSize = [[mMovie attributeForKey:QTMovieCurrentSizeAttribute]
sizeValue];
NSMutableString *sizeString = [NSMutableString string];

movCurrentSize.height -= [mMovieView controllerBarHeight];
[sizeString appendFormat:@"%.0f", movCurrentSize.width];
[sizeString appendString:@" x "];
[sizeString appendFormat:@"%.0f", movCurrentSize.height];
[mCurrentSize setStringValue:sizeString];
12. To set the source text field, add:
- (void)setSource:(NSString *)name
{
NSArray *pathComponents = [[NSFileManager defaultManager]
componentsToDisplayForPath:name];
NSEnumerator *pathEnumerator = [pathComponents objectEnumerator];
NSString *component = [pathEnumerator nextObject];
NSMutableString *displayablePath = [NSMutableString string];
}
while (component != nil) {
if ([component length] > 0) {
[displayablePath appendString:component];
}
component = [pathEnumerator nextObject];
if (component != nil)
[displayablePath appendString:@":"];
} else {
component = [pathEnumerator nextObject];
}
[mSourceName setStringValue:displayablePath];
