I'm trying to make an NSTextView do something rational when someone drags a
token from an NSTokenField. So I've got the NSTokenField producing a custom
drag type I've called TokenPboardType.
I've inherited from NSTextView and redefined readablePasteboardTypes to be:
- (NSArray*)readablePasteboardTypes; {
NSMutableArray*rtn = [NSMutableArrayarrayWithObject:TokenPboardType];
[rtn addObjectsFromArray:[superreadablePasteboardTypes]];
returnrtn;
}
and I redefined - (BOOL)readSelectionFromPasteboard:(NSPasteboard*)pboard
type:(NSString*)type;
to do what I want.
My trouble is that when I redefine -
(NSString*)preferredPasteboardTypeFromArray:(NSArray*)availableTypes
restrictedToTypesFromArray:(NSArray*)allowedTypes;
This method's list of allowedTypes when I do the drag doesn't include my
TokenPboardType. Now if I return TokenPboardType anyway, it seems to work. my
readSelectionFromPasteboard gets called with TokenPboardType and it all seems
to work. But it feels like I'm doing the wrong thing somehow, since from the
doco it sounds like you shouldn't return a type that is not in the allowedTypes.
