Or you can use displayBlock: (and root: and children:) directly on the TreeModel. tree := self newTree. tree roots: { root1 root2 }; displayBlock: [ :node | node label ]; childrenBlock: [ :node | node children ]; iconBlock: [ :node | node icon ]. I'm not sure if direct creation of TreeColumnModel/TreeNodeModel is advised considering TreeModel is trying to hide it.

Hi,
I have a TreeModel with different kinds of TreeNodeModel and I would like to get a customizable display string depending on the node type. It looks like it is not possible to dispatch on nodes in a display block because it only takes the item (node content) and the tree as parameter. It is strange as I expect that to be a standard feature. Do I miss something?
I found a workaround and it looks like a missing feature in Spec TreeModel. You can customize the display by settings columns on the tree like this:
self newTree columns: { TreeColumnModel new displayBlock: [:node | node label ] };
