All right here is my predicament this time, originally I was using -setRepresentedFilename: to set the proxy icon for my program, however it leaks and naturally this isn’t acceptable! Thus I have tried to go into carbon to get what I need done, but I have failed, here is what I have attempted:

		NSURL * URLPath = [NSURL URLWithString:@"/Applications"];
	FSRef fsref;
	FSSpec fsspec;
	
	CFURLGetFSRef((CFURLRef)URLPath,&fsref);
	
	FSGetCatalogInfo(&fsref, 
					 kFSCatInfoNone, 
					 NULL,
					 NULL,
					 &fsspec,
					 NULL);
	
	
	
	void * ref = self window] windowRef];
	[[OSErr err;
	IconRef proxyIcon;
	SInt16 label;
	
	err = GetIconRefFromFile(&fsspec,
					   &proxyIcon,
					   &label);
	
	if (err != noErr)
	{
		NSLog(@"error!");
	}
	
	err = SetWindowProxyIcon(ref,proxyIcon);
	
	if (err != noErr)
	{
		NSLog(@"error!");
	}

If anyone can spot the error you’d make my day.

Doesn’t this only work for Carbon windows?

Cocoa has a compatibility method -windowRef… but never-mind folks, this leaks also (unless you know the fix for that also heh…).

You’ll need to call ReleaseIconRef on proxyIcon

AFAIK you have to call GetIconRefFromFileInfo instead of GetIconRefFromFile in OS X.
