- PortModel can now decide whether or not a link should be allowed (E.g. only allowing outputs to connect to inputs)
- PortModel now has an optional maximum number of links - When set to 1 an existing link is returned by createLinkModel and when set to another finite number null will be returned when the maximum is reached
- LinkModel has been updated to support the resetting of existing links (I.e. removing ports and removing mid-points)
- DiagramWidget has been updated to handle null being returned by createLinkModel as well as an existing link (this also supports an existing link where the link's target port should now be the source port)
- DiagramWidget has been updated to respect the PortModel's new canLinkToPort method
- DiagramWidget has been updated to disallow duplicate links
First simply demonstrates how events can be handled.
Second demonstrates a new functionality: limiting the number of points to be created per link using the new property maxNumberPointsPerLink
