Hi, I am new to GEF.
I want to draw connections from one side of a GraphicalViewer to another
one. As start and end point I have a node. This is done so far.
When resizing the GraphicalViewer I want to change the position of the
nodes on the right side to be still seen. This means I don't want to use
scroll bars. The connections should be visible all the time.
Would look like this:
before:
----------
| |
|o----->o|
| |
|o----->o|
| |
----------
after resizing:
-------------
| |
|o-------->o|
| |
|o-------->o|
| |
-------------
and back again:
--------
| |
|o--->o|
| |
|o--->o|
| |
--------
I know that there are listeners to listen to the resizing of the
GraphicalViewer's control.
Do I have to add all the nodes to listen to this event? I was trying to do
it
with the parent EditPart of the node editparts and call refreshChildren()
but this does not update the children.
Is there some easy way to do this?
Thanks Roman

It seems like you just need to move the nodes, and the connection will
follow.
