Making tktreectrl `just big enough'

Hi all,

I would like to create a tktreectrl which requests only just enough
space to display its contents, but I can't figure out how to do this.
I am mainly interested in setting the height appropriately, rather
than the width.

The -height option has a `0 or negative' value option which I though
might work, but it doesn't. I then tried using the bbox command to
retrieve the actual height of the table, and plug that back in to the -
height config option, but bbox seems to return values which are too
big - the height is always about 1 row too big, leaving an empty gap
at the bottom of the table. The only way I have found that works so
far is to compute the height of an individual row (using item bbox),
multiplying that by the number of visible rows, and then setting the -
height from that.

Surely there must be an easier way. Am I missing something?

I am using tktreectrl 2.2.3 and Tk 8.5.0.

thanks,

dan.
