Greetings,

I'm having some problems with how the nodes and connections are currently rendered.
As it is now I get the feeling that connections are always drawn below the nodes, regardless in what order they are added.
What I need is to either have the connections always drawn above nodes or if I could simply control the order they are drawn myself it would suffice.

I've been trying to implement some workaround this, either by using the Control.moveAbove (this seem futile since from what I can tell nodes and connections aren't composites) or by controlling the order they are added to the canvas (this also seems futile because how they are added is currently hidden inside the Zest framework).

Is there something I've missed which I can use to create a workaround this issue.

Any help is appreciated, even if it is a simple clue.

With Regards,
Mikael

Hi Mikael,

if I recall correctly, Draw2D (the vector library used inside Zest) presents all edges above the nodes in a separate layer. However, even if it is configurable, the Zest API does not offer programmatic support for changing this setting.

I am sorry, but I don't think your use case can be easily supported by Zest.

Cheers,
Zoltán
