Draw lines between two Trees in two ViewParts [message #666343]

I want to write an eclipse RCP application. The main display will have 3 views. Left and right view will show two trees. The middle view will be used to draw lines between nodes of two trees.

When dragging one item on the one tree and dropping it on another item in the other tree I want to draw a line from the one to the other items. I should be able to detect each line because each of these lines have some properties to save as well. When the corresponding item in the tree is collapsed the line
should disappear, when the item gets out of the view the line should
disappear).

After the drawing finished I should be able to save the line along with the properties to a file (an XML) so that it can be open later.

Is it possible to do this at all?

If yes, what would you suggest: use SWT GC, use Draw2D, use GEF to draw the lines.

Any comments will be appreciated.

Thanks,
Aratrik
