Roassal2 and edges

Hi!

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

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...

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
