Graphiti• Framework approach

• Easy to understand (relatively...)• Hides complexity of GEF, Draw2D

• Only few core concepts

•Everything is a Feature

– Add, Update, Move, Delete, ...

• Providers

– Diagram Type Provider,Tool Provider, Image Provider,...

(o"eGeneration )*+) - Marko Boger 8



Graphiti• Much code, often repetitive

implementation

• Per mapped meta class

• at least AddFeature, CreateFeature, UpdateFeature

• Remove, Delete, Move, Layout, DrillDown, ...

• Registration in FeatureProvider

• Configure palette in ToolBehaviourProvider

• Repeat this e.g. for10 meta classes...
