Add a column to a Table [message #1691326]

I have a table of objects that I would like to add a 'derived' column. Sure I can add a derived attribute in my model, but can I do so directly with the Parsley DSL.

      parts {
		viewpart com.verticon.im.view.events {
			viewname "IM History"
			viewclass EventsOnSelectionTableView
		}
	}
	
	featuresProvider{
			features{
				Enity -> events	
			}
	}
		
       featureCaptionProvider{
   	 	text {
   	 		Event : date -> 'Date'
   	 		Event : ^target -> 'Target'
   	 	}
   	}

Would like to add a third column with the name 'Name' to the table which is the name of the type of Event.

Can I do this with the DSL?

Hi John

currently it is not possible to do that with the DSL; at the moment, I
could not come up with a clean solution (in particular, adding a column
header is not that hard, but then we should provide also a way of
specifying the value to be shown in the cell, so this would require to
customize two elements in the end). I think the clean solution is to
have a derived feature in the meta-model as you said yourself.

You could still bind your own custom TableViewerColumnBuilder in Java.

Does that sound good?
cheers
Lorenzo
