Slow scrolling with ScrollPane on a large draw2d figure [message #1062902]

Hi All,

I have been using draw2d library (not GEF) and ScrollPane. The figure presented in this ScrollPane is a kind of diagram with some Rectangles and Connections and the scrolling is ok, but for big diagram it is very slow (or sometimes Eclipse get crashed). Without the connections everything is enough fast. How can it be done, that the scrolling goes fast also with connections used ?

The solution with scrolling some kind of an image is not applicable, because the user can do some modifications on the diagram, so the bounds of figures are set and Rectangles change the positions.

Thanks in advance.

You have to debug it and find what is the bottleneck. Do you have separate layer for connections?
