I'm in the process of upgrading from 3.5 to 4.1.

I subscribe to PreviewKeyDown (now on the DiagramView, as opposed to my Diagram like before), and call InvalidateVisual() on the link currently being drawn (which I get by using diagram.Interaction?.CurrentItem). I'm also subscribed to my Diagram's DrawLink event.

When I'm in the middle of drawing a link and the mouse moves, the DrawLink event handler is called.  But if the mouse is stationary (with mouse still pressed down) and I tap a key, my PreviewKeyDown event handler runs, but after InvalidateVisual() is called, the DrawLink event handler does not run.

Any ideas as to why DrawLink is not running?

Also, I've noticed the tooltips when mousing over a DiagramNode show up with no delay, while in 3.5, there was the typical system delay. Is there a global way on the Diagram to set the delay back to normal? Or do I need to set the delay on each Node when it has been created?

Thanks!

This build adds ToolTipDelay property to DiagramView:

Hello Slavcho.

On the topic of tooltips again, they get stuck open for me if the mouse leaves the diagram without first hovering over a blank part of the diagram first. As in, if the DiagramView's scrollbars are visible, and I've scrolled so that a node is partly out of view, I can mouse over the visible part of the node to get the tooltip to appear, and then if I move the mouse off the diagram without going to a blank part first, the tooltip flashes and appears wherever I stopped moving the mouse on another part of my application.  And then the tooltip is stuck open until move the mouse back onto the diagram.

Are you seeing this behaviour as well?

Thanks,
Joel.

Unfortunately that doesn't seem to have fixed it. I uninstalled the MindFusion NuGet package, made sure all references were gone, then I copied in the DLLs from the zip and added them as references. So hopefully I did that part right. But I'm still getting the issue with the tooltips getting stuck on.

I will upload an animated GIF of what's happening. I'm only showing a small portion of the application, but you can see the diagram with a TemplatedNode (the blue box that says Output and has a speaker icon), and when I move the mouse outside of the diagram, the tooltip reappears. Even if I move the mouse off the TemplatedNode before the tooltip appears, it still appears. Like as if the timer for the initial delay isn't getting turned off when the mouse leaves the node or the diagram.

Works now.  Thanks!
