hi,

i've a multi page editor part with a scrolled composite and have 2
tree viewers along with few labels on it. and want to draw mapping
lines to interconnect them.
the requirement is :-

-- if i drag mouse from one tree viewer item to drop on a swt label or
on another tree viewer item, it should draw mapping lines with arrow
head on the destination.
--also the tree items may connect to other items in the same tree

But i'm not sure how to start with it. can you please give me some
pointers!

should i first make a dragdetectlistener for each control for the
mouse drag part?
should i pick zest / draw2d / gef?

i'm totally confused now. appreciate any help...

thanks,
ani

I think you can create a composite with Sash for ur Left and Right hand side components and put them on a canvas then u can use draweLine API to drawl links on SWT canvas.

You can always go to GEF connection anchors and that would give you more options .

hello,

thanks for the response.

but i think drawline api draws a static line whereas i want a movable and resizable line which moves when i move my components.

do u have any idea?

thanks,
