  I've been working on the mac for the last 6 months, recently converted from
ibm p.c.  I'm getting my feet wet with controls and resources.  I have been
able to create small apps with standard mac stuff, but would like to design
my own controls.  Inside Macintosh does a lot for stating generalities...
"you need this, and one of these, and, oh!, one of these too..." but no
specific examples in this case.

  So I've tried creating a CDEF which responds only to the draw message and
returns zero (0) for everything else.  It responds, but draws something
completely different than what the code says.  The code inverts a block
of pixels in a window (it works when called from the "main" block of code,
but not when the resource is compiled seperately -- I get a rounded box!)

  Has anyone written custom controls?  If so, do you mind sharing a portion
of your code and development technique?  Also, any help on using Think C
to debug resources would be appreciated.  I have most of the Inside Mac's and
both Programming the Macintosh's (vol 1 and 2)  I have looked elsewhere but
have found nothing with coding examples or techniques.  Book or Article
references would be appreciated as well.

Thanks in advance!
