Cells can be quite useful without associated controls. For instance,
it would be very useful and clean to be able to instantiate a cell in
Interface Builder, set its properties, and then set it as the data cell
for an NSTableColumn or NSBrowser. This would remove the need to
instantiate the cell in code in the controller's -awakeFromNib and set
it up by hand there.
Huh?
NSBrowser is a control.
NSTableColumn needs to be contained in a NSTableView, which is a
control.
Setting a cell to be the data cell of table view's column is
associating a cell with a control, albeit one level removed.
So you must agree that without that association, the cell is for the
most part useless.
I filed a feature request in RADAR a couple years ago (I think) asking
for this ability. As far as I'm concerned, it should be possible to
instantiate *anything* that supports NSCoding in Interface Builder; it
should be up to the developer to make sure that doing so makes sense in
their particular case.
I agree that the way in which IB goes out of its way to defeat the
direct creation of cells brings a degree of complexity to configuring
controls such as table column's cells which does not seem justified.
Let's hope your feature request receives some attention.
Cheers,
Dan
