Hi all, I want to visualise three nested levels of a model. I am not sure if I am doing it right, since I had to add a reference to the view to the nested elements manually to make it work. The problem I face now is that elements in the deepest level do not react to interactions. In the example below, popup is only shown for the elements in the first two levels. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= v := RTView new. es := (RTBox new color: Color white; borderColor: Color lightGray) elementsOn: (Array with: RTLayout with: RTShape with: RTBuilder). v addAll: es. es @ RTPopup. RTNest new for: es add: [ :group :model | elements := (RTBox new color: (Color red alpha: 0.1)) elementsOn: model withAllSubclasses. group addAll: elements. elements @ RTPopup. elements do: [ :e | e view: v ]. RTNest new for: elements add: [ :group2 :model2 | els := (RTBox new color: Color blue) elementsOn: model2 methods. group2 addAll: els. els @ RTPopup. RTTreeLayout on: els edges: edges ]. RTGridLayout on: elements ]. RTGridLayout on: es. v -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Any hint would be much appreciated. Best regards, Leonel
