I used an NSMatrix of NSTextFields to do something similar to what you
are trying to do.  My matrix has 4 text fields

pseudo-code written in mail.

in an IBAction method
        //get the selected cell
	int currentCell = [[myNSMatrixTextField selectedCell] tag];
	float newval;
	if ([sender isKindOfClass: [NSStepper class]] == YES)
	{
		newval = [[myNSMatrixTextField cellAtRow: 0 column: currentCell]
floatValue] + ([sender floatValue] * 0.001);
		[[myNSMatrixTextField cellAtRow: 0 column: currentCell]
setFloatValue: newval];
		[sender setIntValue:0];
	}

my stepper has a very large min and max value, increments by one and
the values wrap.

I imagine that if you want to change the min and max values of the
stepper, you could grab the values from the matrix and update the
stepper.

You probably want to use the NSTextField delegate method -
controlTextDidEndEditing:.
