I have a document based Cocoa app.
I want to do stuff to it's window, like set the title of the window
when I open a file. However, I can't figure out how to get an
NSWindow from the NSDocument. I tried this:
I went a different route - instead of fiddling with the window
directly, my implementation of readFromURL sets the properties that
the window would be reading later to set the title.
The following code is part of a Core Data app that can also read and
write "Tab Delimited Sector" and "Sector" files, but since those are
lossy, I want an 'untitled' window to show up when you open one.
- (BOOL)readFromURL:(NSURL *)absoluteURL ofType:(NSString *)typeName
error:(NSError **)outError{
NSLog(@"rFU: %@ %@",absoluteURL, typeName);
if ([typeName isEqualToString:@"Tab Delimited Sector"] ||
[typeName isEqualToString:@"Sector"]){
NSString * data = [NSString
stringWithContentsOfURL:absoluteURL
encoding:NSMacOSRomanStringEncoding error:outError];
if (data==nil){
NSLog(@"Error reading file at %@: %@", [absoluteURL
path], outError);
return NO;
} else {
[self setFromString:data];
[self setFileType:@"Binary"];
[self setFileURL:nil];
[self refreshEverything];
return YES;
}
} else {
return [super readFromURL:absoluteURL ofType:typeName
error:outError];
}
}
This might be an end run around needing to futz with the Window
directly.
