Frame size

[Beast <beast i6x org>]

I have frame inside frame

                                   e
+-Frame A ---------------------+   ^
|                              |   |
|  +-Frame B ------+           |   v
|  |               |           |   f
|  | [child label] |           |
|  |               |           |
|  +---------------+           |
+------------------------------+

a<->b              c<---------->d



1. How do I set the cellpadding (a-b and e-f)?
2. How to make child frame width depends on the longest child label?


Im trying to set using $frameb->set_size_request(100, -1) but the width 
is always 100%

Thanks.
