How to identify the node position

GoJS
1

how to identify if the node is on left/right/bottom/top comparative to another node? I tried using Rect.left, doesn’t give correct position.

2

Either compare their locations, which are Points, or compare their actualBounds, which are Rects.

3

is there any way to get the old location of the node before drag?

4

Not in general. If you have enabled the UndoManager, you could look it up in its history. But that’s a bunch of searches you would need to implement.

5

any example for using draggingTool.computeEffectiveCollection which uses draggingInfo to store old location?

6

Oh, right:

const tool = myDiagram.toolManager.draggingTool;
const info = (tool.draggedParts ? tool.copiedParts).get(node);
if (info) ... info.point ...

Thanks, I was able to get the old location before the drag, but it makes the app slow, I am moving nodes using part.MoveTo, nodes doesn’t even move sometimes.

Please start over again. What are you trying to accomplish?
