I see that WEF has dojo drag and drop builders. Could I use these builders as the basis of a palette-and-canvas application?
The customer wants to build a query visually: the user drags icons from a palette to the canvas. Each icon and its connectors has a meaning as part of a query; I build the query according to the icons and their connectors.
Is WEF the right tool for this application?
Is there a sample application that does this sort of thing?
