Q:  What is the difference between a Form and a FormCell?  How do I make the correct connections in InterfaceBuilder?

A:  A Form is a matrix of FormCells.  Even a matrix with only one FormCell is a Form.  If you have created a single FormCell with InterfaceBuilder and want to connect to the Form, carefully control-drag to the edge of the cell.  When it is outlined in gray, you are connecting to the Form.  Control-drag further into cell, and it is outlined in black; now you are connecting to the FormCell.  Look at the "Comments" field in the InterfaceBuilder inspector while you are making your connection--it tells you what class the outlet is, for example, "Destination is of the Form Class."  The same is true when you are connecting to a Form with more than one FormCell.  Drag to the outside edge or in between cells; the form is outlined in gray and you are connecting to the form.  Drag to a particular FormCell; it is outlined in black and you are connecting to that FormCell.

Note: In NEXTSTEP Release 3, the "Comments" field in the InterfaceBuilder Inspector has been replaced by a "Connections" field. The information displayed is self-explanatory: The left side shows the outlet name, while the right side shows the class name.
