Hi! As you may know, Mondrian offers additional interaction mechanisms. The script below shows a system complexity, and by waving the mouse over a node, clientClasses will be connected. When the mouse leaves the node, the edges disappear. -=-=-=-=-=-=-=-=-=-=-=-= view shape rectangle width: #numberOfAttributes; height: #numberOfMethods; linearFillColor: #numberOfLinesOfCode within: classGroup. view interaction action: #inspect; whenEnteringUpdateNode: [:node | view edges: {node} from: #yourself toAll: #clientClasses ] withLayoutUpdate: false. view nodes: classGroup. view edgesFrom: #superclass. view treeLayout -=-=-=-=-=-=-=-=-=-=-=-= This mechanism is useful I think, however, the block you provide in #whenEnteringUpdateNode: should be error free. Else the image may hang (this is a well known Morphic problem, I will work on it one day). Do you like this view? Would it make sense to make it as default in Moose? Any comment?
