Hi Jannik, I do not understand :). The layout is here: MOTreeLayout. The most important method is: layout: aNodeCollection atPoint: aPoint atLayer: aNumber This is a recursive function that places aNodeCollection starting with aPoint and then calls for each node the same method to layout the rest of the tree.
