30/01/16 13:04
Some time ago we published an improved Hello World tutorial that shows you how to get started with Dolphin and its default user interface framework, Model View Presenter. With the recent release of Dolphin 7 to a wider open source audience, it seems useful to republish this. If you’re new to Dolphin, be sure to check out our Getting Started page first… More…
