Is this based at all on the ExtJS Screen Designer?

[Profound Logic]

Question:
Is this based at all on the ExtJS Screen Designer or is this your own designer? It seems much better than the ExtJS one is why I ask.

Answer:
This is not at all based on the ExtJS Screen Designer. The panel and toolbar framework of the designer application is done using the ExtJS component library, but the real design functionality (the widgets, canvas, dragging/dropping, properties window, etc.) are all custom-developed. The widgets themselves are also custom developed to be specific to IBM i / RPG programming.
