Hidden item names begin with a "." In your enumeration, check the name
for this condition to find hidden files. If you wish to fine tune your search
for specific types of files/folders, try something like:
- (BOOL)prepareForDragOperation:(id < NSDraggingInfo >)sender
{
//check if it is a directory or volume
dropFile = [[self getFile:sender] objectAtIndex:0];
NSWorkspace *ws = [NSWorkspace sharedWorkspace];
NSString *uti = [ws typeOfFile:dropFile error:NULL];
if ([uti isEqualToString:@"public.folder"]) {return YES;}
if ([uti isEqualToString:@"public.volume"]) {return YES;}
[self draggingExited:sender];
return NO;
}
This code permits dropping of regular old folders & volumes but not anything
else (as far as I know!)_______________________________________________
