Hi guys, Need some advice.
I'm working on a Supply Chain simulation system build on J (obviously). My initial design was built using C# as front-end handling data entry and manipulation for data stored on an MS-SQL server. J obviously does the computation and leaves the front-end stuff to C#. Currently, all UI's are using Grids ... or excel like if you prefer. Unfortunately, after last week, my boss wants a 2D graphical UI. Icons would represent entities and process inside the supply chain with linking arrows visualizing the flow. The idea is to provide users with an icon/flowchart based GUI allowing them to change properties, values, KPI's in the supply chain and letting it run. So my dilemma right now is choosing a direction for 2D graphics. I'm currently looking at the following: 1. J 's built-in GL2 commands 2. Go low level GDI+ in .NET 3. Use 3rd party libraries like a. Gorgon 2D Library for .NET <http://tape-worm.net/> b. Piccolo2D Library for .NET <http://www.piccolo2d.org/> To put it simply (not so simple actually), I just need to let users drop an icon/image on a canvass, drag arrows between images and be able to maintain the arrows even if one of the objects are dragged. I would appreciate it if somebody have some insight, suggestions, ideas, violent reaction that can point me in the right direction ... Thanks. r/Alex ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
