[Moose-dev] node: forIt: in Roassal takes too long

Hello, I am trying to arrange two sets of nodes in verticalLineLayout with Roassal, and within a set, the nodes are arranged in a gridLayout. The script below allows works fine except that the execution time is too long when the number of nodes is large and hence I am unable to achieve multi-layout visualization for large number of nodes. view := ROMondrianViewBuilder new. view shape rectangle withoutBorder. view node:#aaa forIt:[ view shape rectangle. view nodes: (1 to: 10000). view gridLayout. ]. view shape rectangle withoutBorder. view node:#bbb forIt:[ view shape rectangle. view nodes: (1 to: 1000). view gridLayout. ]. view verticalLineLayout. view open Can you please have a look or could you suggest an alternate solution? I have created my own custom layout but that is tied to the structure of my nodes and hence not generic. tx. usman
