Is it possible to include a radio group of 3 buttons for a table column? Any help is appreciated.
It is not provided out of the box.
What I would recommend:
Implement your own renderer and editor based on the existing boolean checkbox renderer and editor. Implementing a radio button should be quite easy - just adapt the sensitive area in the editor and draw appropriate radio buttons in a new renderer.
I would recommend to place every radio button in a separate column to keep that scalable. Using spanned cells, the user should not see any difference.
If it does not need to be a radio button (a checkbox is ok), you can also use the existing editors/renderers for that - this would drastically reduce the necessary effort.
Sorry was away for some time. That sounds very helpful. I'll give it a try.
Btw, could you provide a little code sample of TableCellEditorDialog?
