Selection dialogue

[jop_008]

I am searching for the following functionality:

I want to select items out of a list (some times only 1 can be selected which is easy)
In case of multiple items one must select the items (one by one or select a view items and bring them over to the selected items.
The select items can be reordered by the user.
I was thinking of two list items and split the screen vertically. On the right the selected items and on the left the items to choose from.
It must be possible to select all, deselect all.
Any help appreciated.

I've made a panel with a hbox and split the screen vertically.
On the list items on both sides I've put config item multi.
The buttons under the two lists take care of shooting things from left to right vv.
The code will be part of the open-modeling framework (see sourceforge).
