/****************************************************************************
CLASS: MiscGaugeCell
INHERITS FROM: Cell
PROGRAMMER: Todd Thomas, Copyright 1995
DATE BEGAN: March 09, 1995
LAST CHANGED: March 21, 1995
VERSION: 0.4
CHANGES: See the end of the implementation file.
This class takes care of everything needed to display a gauge. It
should also be pretty easy to use your own gauge face and hand in
a subclass by overriding drawHand:flipped: and drawFace:. See the
documentation for more details.
We inherit from Cell (and not from SliderCell or ActionCell)
because I thought gauges were basically for showing values, not
altering them.
The guts of this class originally came from the GaugeView in the
BusyBox example located in /NextDeveloper/Examples/Appkit. I
basically copied the code here, changed the pswraps to allow for
color, changed the method names and used inherited cell methods,
and replaced the cache window with an NXImage.
See the implementation file for the original comments that came
with the GaugeView. (I suppose you could also find it in the
/NextDev/Examples directory).
