Hi all,
I am having an issue with setting up a Roassal layout. I guess that to make force based layouts work, I have to add the line
view edges do: [ :e | e trachelShape pushBack ].
However when I do this, there is a MNU in TRCompositeShape>>pushback, because the canvas instvar is nil. I am doing what is essentially the following code:
“in a loop, adding to an edges collection” edges add: (((RTEdge from: efrom to: eto) + (RTLine new color: color) + (RTArrow new color: color)) @ (RTLabelled new text: trans name; color: color; view: view)).
“later"
“adding the edges to the view all at once and do layout magic" view addAll: edges. view edges do: [ :e | e trachelShape pushBack ]. “<— MNU”
What should I do to fix this?
