A cell is usually a component of a view. The view is the responder, but I presume the -acceptsFirstResponder method in NSCell is really there so that the host view can defer to its cell to answer that question. If you want to use the cell in a standard view, such as a tableview , matrix, or other control, you'll have to figure out how those classes interact with their cells. If it's in a custom view of your own, you can probably be more loose with how you do it, if compatibility with standard controls isn't required. Though in that case, you could just make a custom view. --Graham _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
