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...

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
===
