Speaking of which, I've got a tcl proc which calculates the new geometry for
the dialog popup ok, but with one caveat: I always have to explicitly set
the width and height of the box before calling my proc.  Whenever I try to
retrieve the geometry of the dialog box, wm geometry returns 0x0+0+0.

If I was using Xt, I would probably first realize the box to let its height
and width be set, then calculate the position and then map the shell.  There
doesn't seem to be a way to do the equivalent in tk.  It looks like pack is
supposed to map the windows it manages, but calling wm geometry after packing
still returns zeros.  Is there a way to get the height and width before it
becomes visible?
