Hi Kurt,
My main problem is to draw a line from source node to
target node.
To draw a line I need start and end coordinates of the
source and target nodes respectively. How do I get the
coordinates of each node????
When I resize the window then again the coordinates
have to be calculated to paint lines for each
connected tree node.
All thoughts are welcome????
Thanks
Dennis
