Real time autorouting of links? (Read 4728 times)

	Is this possible - link autoroutes in realtime whilst the node is being moved instead of when mouse is released? Currently only first/2nd segment dynamically change. I can post a video of what I'm talking about..

	You could call RouteAllLinks from the NodeModifying event: Code private void diagram_NodeModifying(object sender, NodeValidationEventArgs e) { diagram.RouteAllLinks(); diagramView.RecreateCacheImage(); } I hope that helps, Stoyan

	Not really. Add it to the Demo app and try it on various diagrams, it's slow (moving a node around results in constant 100% cpu utilisation) and obviously affects all the links.

	RouteAllLinks wasn't slow at all in our test, using the new QuickRouter algorithm. If you prefer to use GridRouter or there are many links in the diagram, instead of RouteAllLinks you could call diagram.LinkRouter.RouteLinks(someLinks). Add to someLinks the links returned by e.Node.GetAllLinks(), and possibly the ones in the current e.Node.Bounds vicinity. I hope that helps, Stoyan

	Also tried this which is better, and removed the RecreateCacheImage (cpu utilisation drops considerably) but it's still not quite right. I think you know what I'm after.. Code foreach (DiagramLink link in e.Node.IncomingLinks) link.Route(); foreach (DiagramLink link in e.Node.OutgoingLinks) link.Route();

	Check my post from two minutes before yours... Calling Route() for each link individually will not prevent link overlapping, whereas LinkRouter.RouteLinks will process the links in a batch and distribute them uniformly if possible.

	Thanks, have just tried it with Demo app and it's better.. Please look at video here (use open source Media Player Classic link I posted previously), you'll see what I'd like to achieve. It's one of the only areas that matters where FlowChart is a bit weak compared to others I evaluated. http://www.enetworks.co.nz/images/LinkRouting.avi The desired link routing is very fluid/smooth.

	Have also tried GridRouter which I thinks work a little better again but still jerky. CPU is at 90% moving the node around with 2 Cascading incoming links though.

	It seems the main problem is that the Route method does not preserve the length of the links' end segments. For now you could add some code to move ControlPoints[1] and ControlPoints[Count - 2] to a fixed offset from the end points after routing. We'll add some property to preserve the segment lengths for the next release. Stoyan

	How about just adding a property to make it work like the 'other' product?

	If you do add this feature, i'll name my first born after you, even if it's a girl.
