I've been attempting to write my first X program using the Athena
widget set (for portability).  Everything was going along fine until
I tried to create a widget to draw to.  I was using a Label widget
and trying to create a bitmap (I know, depth=1) using XCreatePixmap,
and then using XSetArg and XSetValues to load the info into the Label
widget's resource. I was a bit confused as to what to specify as the
window in XCreatePixmap; I've tried both the LAbel widget itself, and
an independent window I created using XCreateSimpleWindow.  No matter,
in both cases as soon as I tried to load the bitmap into the Label
widget's bitmap resource, i got the following message:

X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  1 (X_CreateWindow)
  Minor opcode of failed request:  0
  Resource id in failed request:  0x72610
  Serial number of failed request:  46
  Current serial number in output stream:  48

What?  Help?  I'd really like to know how to make this work.  I'd
especially like to know of a solution that doesn't require me to 
resize the bitmap everytime the aplication is resized.  I'd be
especially overjoyed to learn where I can get a sample Athena Toolkit
program that does the right thing.

Thanks,
