Re: NSTokenfield: Drag and Drop / Autocompletion

the second problem:
i have implement drop functions in the nstokenfield. this works only when i drag the file to the border of the tokenfield but not when i drag the file in tokenfield. i think the problem is the nstokentextview subview in the nstokenfield and specific nstokenfield drag and drop methodes for draging tokens. 

Phillipe,

I found a workaround for that. Problem is the NSTokenField having firstResponder state. Please see my solution in a subclass of NSTokenField:


- (NSDragOperation)draggingEntered:(id <NSDraggingInfo>)sender
{
	NSResponder *currentFirstResponder = [[self window] firstResponder];
	
	if( currentFirstResponder &&
	    [currentFirstResponder respondsToSelector:@selector( delegate )] &&
	    [currentFirstResponder delegate] == self )
	{
		[[self window] makeFirstResponder:[self window]];
	}
	
	return NSDragOperationAll;
}


Cheers,

Robert
