Hi!

I am not sure to understand. Why do you use a GraphBuilder?

For the example. I could use something else.

Cheers, Jannik

I think I have spotted something. For example:

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= v := RTView new. shape := RTShapeBuilder new. shape shape: (RTEllipse new color: Color gray; size: 40).

el := (RTElement on: 1). el + shape. v add: el. el @ RTDraggable.

el2 := (RTElement on: 2). el2 + shape. v add: el2. el2 @ RTDraggable.

lineShape := (RTLine new color: Color red) "+ (RTSimpleArrowHead new color: Color red)". l := lineShape edgeFrom: el to: el2. v add: l.

RTCellLayout on: b view elements. v -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Uncommenting behaves oddly. I will look into this...

Alexandre

Hi Alex,

I have some problems with displaying edges. I have difficulties to reproduce things outside my application. But I am trying to add arrows. So when I do: (RTLine new color: Color red) + (RTSimpleArrowHead new color: Color red), the text that follow the + brake my visualization: the arrow is wrongly placed. If I remove the + (RTSimpleArrowHead new color: Color red), it works fine.

When I tried to reproduce it, I created an example that does not work, I do not understand why:

=== b := RTGraphBuilder new. shape := RTShapeBuilder new. shape shape: (RTEllipse new color: Color gray; size: 40).

el := (RTElement on: 1). el + shape. b view add: el.

el2 := (RTElement on: 2). el2 + shape. b view add: el2.

l := RTEdge from: el to: el2. b view add: l.

RTCellLayout on: b view elements. b build. b open ===
