Source ports and target ports

[elgransan]

Hi, it is possible to set a port as only source and other as only target?

Hello,

You can create a custom class and inherit from PortModel, then override CanAttachTo to include whatever logic you need. In your case, a simple bool property IsSource for example can do the job, then the new method could look something like:

public override bool CanAttachTo(PortModel port)
            => base.CanAttachTo(port) && IsSource != port.IsSource;

Hi thanks it's working perfect using aligments in this way

public override bool CanAttachTo(PortModel port) => Alignment == PortAlignment.Bottom && port.Alignment == PortAlignment.Top;

But I had to remove base method call because I couldn't connect itself, It's the correct way to allow connecting itself?

Thanks!
