How to get current node immediately (mousemove)?

Hi,
I want to do dynamic highlighting of rows in the table after moving the mouse over them. That is why i need this data immediately and that is why i cant use event "NodePointed" because of his little lag.
I created the "mousemove" handle.
1. The conversion of the x / y parameters of the document to the proper ones used on the canvas works correctly.
2. but I can't execute the "GetNodeAt" method without error.
Something is wrong... I've tried all night in all ways but it doesn't want to take the parameter, I don't know why.

Here is a screenshot that shows this error. I have this error often when I just give the wrong parameter.


Anyone have an idea what i am doing wrong?


Regards,
poor student Cry

I already fix that, i don't know why is this working. Can someone tell me what is diffrent beetwen PivotPoint and normal var point?

This code works well:
Code (Javascript)
Select All
var point = PivotPoint.Point;
point.x = diagram.pointerPosition.x;
point.y = diagram.pointerPosition.y;
var tableNode = diagram.getNodeAt(point);

Proper name of the method is getNodeAt (in our JavaScript library at least), and since JavaScript is case-sensitive, in your first try it complains the upper-cased GetNodeAt does not exist. PivotPoint.Point is some random class from libraries you are using I guess, and you are adding x,y fields to it, which getNodeAt then happily uses.
