[Moose-dev] Re: Mondrian question

I see the problem you're facing. Indeed, the syntax of Mondrian is a bit unintuitive. I recently introduced edgesFromAssociations: that makes it simpler to define edges. Consider the script: -=-=-=-=-=-=-=-= view nodes: (1 to: 5). view edgesFromAssociations: {1 -> 3 . 1 -> 5} -=-=-=-=-=-=-=-= The reason of "edges: nodes from: b1 to: b2" is to produce as much edges as there are nodes. For each node, an edge is created by evaluating b1 and b2 against the node. The interaction in Mondrian works well, but I agree this is a bit rough to use. The following: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= view interaction whenEnteringUpdateNode: [:node | view edges: {node} from: #yourself toAll: #sureReferencingClasses.]. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= means that when you enter the node, you replace everything under the node with some edges. You therefore discard the classes in it. I propose two versions of your code. A long (and ugly one), and a much nicer one, but which does a slightly different thing: The script draw edges between a packages and classes. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= view interaction whenEnteringUpdateNode: [:node | view shape rectangle fillColor: Color orange; height: 7; width: 7. view nodes: node classes. view gridLayout gapSize: 2. view edges: {node} from: #yourself toAll: #sureReferencingClasses ] whenLeavingUpdateNode: [:node | view shape rectangle fillColor: Color orange; height: 7; width: 7. view nodes: node classes. view gridLayout gapSize: 2 ] withLayoutUpdate: true. view nodes: model allPackages forEach: [:pack | view shape rectangle fillColor: Color orange; height: 7; width: 7. view nodes: pack classes. view gridLayout gapSize: 2. ]. view gridLayout. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= This version draws edges between classes -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= view nodes: model allPackages forEach: [:pack | view shape rectangle fillColor: Color orange; height: 7; width: 7. view interaction whenEnteringUpdateNode: [:node | view edges: {node} from: #yourself toAll: #sureReferencingClasses ]. view nodes: pack classes. view gridLayout gapSize: 2. ]. view gridLayout. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-= -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
