Excuse me if I wasn�t clear but I hope this explains:
I draw several nodes with PointArray() class and structural elements with
LineArray() class, I want that when the mouse is moving around any part of the line
or point elements it identifies the corresponding coordinates, for this I�ve
assigned a Behavior
wakeupOn (new WakeupOnAWTEvent(MouseEvent.MOUSE_MOVED)); for each line with mode
pickCanvas.setMode(PickCanvas. GEOMETRY_INTERSECT_INFO) but is very slow detecting
the mouse moving. I know that with pickCanvas.setMode(PickCanvas.BOUNDS) is better
but it throws the attached Exception.
To solve this Exception in PointArray() I assign a TransformGroup for each new
Point. But how can I solve this problem for the LineArray()?
Thanks for your time,
Carlos.
