Hey guys,

I'm having trouble of thinking out a way to put files/folders from a preset folder into a NSOutlineView, basically I can currently get a folders contents and put it all into a NSOutlineView, but the objects in the outline view are just single files and are not organized like it should be, in correct folders. Here is my current code:

Code:
- (void)processFolder:(NSString *)path
{
	NSFileManager *fileManager = [NSFileManager defaultManager];
	NSDirectoryEnumerator *fileEnumerator = [fileManager enumeratorAtPath:path];
	NSString *fileString;
    while (fileString = [fileEnumerator nextObject])
	{
		NSString *filePath = [path stringByAppendingString:fileString];
		NSFileWrapper *fileWrapper = [[NSFileWrapper alloc] initWithPath:filePath];
		if ([fileWrapper isDirectory])
		{
			File *folderGroup = [[File alloc] initWithParent:rootProject withName:[filePath lastPathComponent] withPath:filePath withContents:nil isGroup:YES isDocument:NO];
			[rootProject addFile:folderGroup];
			[self processFolder:filePath];
		}
		else
		{
			File *fileDocument = [[File alloc] initWithParent: rootProject withName:[filePath lastPathComponent] withPath:filePath withContents:[NSString stringWithContentsOfFile:filePath] isGroup:NO isDocument:YES];
			[rootProject addFile:fileDocument];
		}
	}
	[outlineView reloadData];
}

Basically what happens is I just get the path of the folder, use a NSDirectoryEnumerator to go through it and get all its contents, I then use NSFileWrapper to tell if a file is a folder, and if it is, add a File object as a folder, if its not, add it as a normal document. So I end up with a 1 level NSOutlineView with all the files and folders in a list. Ideally I'd like the correct files to be in the correct folders, but I just can't think of how to go about this. The parent of the file and where its added depends on where its added in the Outline View.

EDIT: I have seen the OutlineView.pbproj project, but its not what I would like. It basically does it all from inside the equivalent of my File class, but I'd like to keep the File class flexible, and I'd prefer to do all the processing in the controller class.

Any ideas appreciated,
Oliver

Look at OutlineView.pbproject again. That shows everything you need to know in order to do this. If you want to refactor the classes, you can do so, but all the tools you need are in that example. If you can't do it with your current class set, I don't know why you think what you have now is "flexible." What you need is some sort of tree like the sample code demonstrates. I don't know what more you expect us to tell you unless we're just supposed to write the code for you.
