Ben, Given that the number of columns is variable in my scenario... is there a way to set a fixed width to each column and display an horizontal scrollbar on bottom? You told me that's not supported by Spec, but maybe there is a way to workaround it inserting a Morph or something like that.

This is a nightmare to solve :)

Hello folks,

When I evaluate in latest Pharo 3:

DynamicComposableModel new instantiateModels: #( a TreeModel b TreeModel c TreeModel); openWithSpecLayout: (SpecLayout composed newColumn: [ :column | column newRow: [ :row | row newColumn: #a. row newColumn: #b. row newColumn: #c width: 80 ] ]; yourself)

===>

Maybe I'm wrong: I expected that #a and #b have the same width. But it looks like the layout algorithm first splits the space half/half between #a and #b, and later it only shrinks #b to give the fixed space to #c.

Should I report an issue? or specify layout in other way?

Thanks, Martín
