Hi, I am playing with ROForceBasedLayout, and I just realize that it does not take into account the size of nodes. That is a pity. For example, if you execute: view nodes: (1 to: 100). view edgesFrom: [ :x | x // 5 ]. view forceBasedLayout ... you get a nice picture. But, if you execute: view shape rectangle size: #yourself. view nodes: (1 to: 100). view edgesFrom: [ :x | x // 5 ]. view forceBasedLayout ... you get a messy one with overlapping nodes. Would it be difficult to make the layout react to the size of nodes? Cheers, Doru -- www.tudorgirba.com "Every thing has its own flow"
