ScrollY

I am not getting any values back from diagram.getScrollX() or getScrollY() after the diagram has been scrolled  They work fine in the animations demo,but my own code is embedded in some JQX tabs and splitters, any ideas??
Where might I find the raw values for the scroll bars? diagram.context.canvas.????
The diagram also has a zoomer control, zoom works but the zoomer buttons to control the scroll do nothing as well.

Do you mean you are getting undefined values? What happens if you trace through this code with debugger?

Code
Select All
if (diagram.scroller)
{
	var scrollOffset = new Point(
		diagram.scroller.scrollLeft,
		diagram.scroller.scrollTop);
}
else
{
	var scrollOffset = new Point(
		diagram.get_element().parentNode.scrollLeft,
		diagram.get_element().parentNode.scrollTop);
}
var scrollY = diagram.clientToDocOverflow(scrollOffset).y;

Stoya
thank you
the values returned were 0
however while testing your code I realized that some html was corrupted in the div the diagram was in, it is all working now
sorry my unfamiliarity with JS and HTML
