Hi Todd,

I think this is a great module - a colleague here has
written a similar thing some years ago, but that was
not as elegant as yours.

I'd like to suggest to add methods to modify the
right hand side list as well (e.g. AddItemRight,
DeleteItemRight). The application I am thinking of
is a derived widget that offers the user to
* select existing items from the left list
* add new items with a text field + add button to
  the right list
You already said you are considering to implement
this as an option to this widget, but the above is
very cheap and allows the derived widget to choose
an arbitrary arrangement of the "Add new..."
button and/or fields.

In an attempt to appreciate your work, I reviewed
the POD and tried to adapt it to a more "standard"
style, and fixing some bad POD syntax on the way.
Feel free to use it (or not) :-)

Cheers,

Marek

Subject: RFC - Tk::DualLists

Hello,

    I recently had need to implement two list widgets with
the ability to move items between them.  There didn't seem
to be a comparable widget out on CPAN.  So, rather than just
put the code in the script, it was made into a module.

    It is attached with a test program as well.  The main pieces
are there.  A couple of small issues like custom sorting
of the lists, allowing duplicate entries, etc. need to be
implemented to make it more flexible.  Also the ability to
display a widget allowing the user to add items without
needing to write extra code would be nice.

    If any of the more knowledgeable Tk hackers would care to
comment, I'd appreciate it.  Tips, pointers, suggestions and
even gentle flames welcome...  If you have any serious flaming
to do, please wait until December or January.  The additional
heat will be welcome in the New England weather  ;-)

    Thanks in advance.

- Todd
