Setting of coordinates or "d" attr values for Manhattan edges #957
Comments
ok, I got it . I will check it as soon as possible. |
butterfly-dag@4.3.28 has fix it. You can call 'edge.getBreakPoints' to get edge breakpoints data and save to backend. Next time draw you dag , you can put breakpoints data to you edge data, for example
|
Can I get breakpoints and the edge info by dragging the edge with React? I don't use canvas.draw and I don't understand how to use 'edge.getBreakPoints' . I provide the state with options, edges, nodes as configuredData like this:
Also I can see some info inside ref.current.canvas. But I can't get any info about Edge on the drag event, because it is simple without id or data attributes. UPD: |
em....We will abandone react-butterfly , I recommend you use butterfly-dag. |
That's a pity(
or, I still use React-Butterfly, but I will use {Edge} from 'butterfly-dag' and provide edge data to React-Butterfly like this:
it seems, it doesn't fully work |
I use the Manhattan edge type with the draggable ability. I save each change in the graph, send it to the server, and remount the graph with updated data. I can save node coordinates, endpoints and connections between nodes. But I can't save changing the path of the edges.
Apparently, svg paths are calculated according to the coordinates and sizes of the nodes, and there is no way to set the value of the d attribute before the component mounting.
This is an important feature for changing the path of Manhattan lines. I'd like to have some kind of access from the react-butterfly event
