[ Jeez, I can't believe that this is giving me so much trouble... ]

I am writing a program (using THINK C 4.0, if anyone cares), which has
two windows open simultaneously.

Both windows are zoomDocProcs, so I have a set of scroll bars for both.

What is the easiest way to know which scroll bars to size when the user
resizes a window?

I know that I *could* find out which window it is, and then figure out
which ControlHandles I used to first set up the windows, but I want to
make a generic "UpdateScrollBars" function, passing only a WindowPtr
(or WindowPeek) variable to it.

I originally thought that I could traverse the list of controls that 
are attached to the controlList of the WindowRecord, but I can't see
an easy way to identify which controls are scroll bars (once I do that,
I would look at the contrlRect to determine right or bottom scroll bar).

Does the ControlHandle tell which ControlDefProc ID I specified at
creation?

Any help would be appreciated, in a big way.

Thanks in advance,

  --Jerry
