limiting dataset combo box column values to choices only

Hi Mark,

maybe I have something you are looking for. The package DatasetMenuButton is attached.

HTH,

A MenuButton for the Aragon DataSet

This package provides a MenuButton to be embedded in columns of a DataSet. It has a drop down list from which an item can be selected. The selected item can not be edited.

Do
        ExampleUI open
for a simple example.

The code is used in production in smallCharts, but will not be maintained. This work is obsolete when moving to Widgetry.

Basically this is a small collection of bug fixes to make this work. One override was necessary.

I didnt check if it would work with the regular DataSet, because I never used it.

Have fun,
