Drag & Drop Problem

[Andreas Höschler]

Hi all,

in a NSView subclass I do

- (void)setDroppingEnabled:(BOOL)flag
{
   if (flag) [self registerForDraggedTypes:[self pboardTypes]];
   else [self unregisterDraggedTypes];
}

- (NSArray *)pboardTypes
{
   return [NSArray arrayWithObject:SOObjectsPboardType];
}

- (void)mouseDown:(NSEvent *)theEvent
{
   ...
            NSArray *pboardTypes = [self pboardTypes];
            [pboard declareTypes:pboardTypes owner:self];
            [pboard setPropertyList:[array 
valueForKey:@"stringRepresentation"] forType:SOObjectsPboardType];
            [self dragImage:dragImage at:mouseLoc offset:dragOffset 
event:theEvent pasteboard:pboard source:self slideBack:YES];
}

- (NSDragOperation)draggingEntered:(id <NSDraggingInfo>)sender
{
   NSLog(@"draggingEntered %@", sender);
   return NSDragOperationLink;
}

- (BOOL)performDragOperation:(id <NSDraggingInfo>)sender
{
  ...
}

This works under MacOSX as expected. Under GNUstep draggingEntered and 
performDragOperation is never called when I drag the object over the 
view and GNUstep shows the "do not enter sign".

What am i missing?

Thanks,

  Andreas
