Hi all,
I have 2 ScrollingGraphicalViewers let say v1 and v2.
Then these are on a composite comp via
v1.createControl(comp) and v2.createControl(comp)
The 2 viewer are shown in the GUI and each one scroll without any problem.
Now I tried to share the range model and used the following code
FigureCanvas canvas1 = (FigureCanvas) v1.getControl();
RangeModel sharedRange = canvas.getViewport().getHorizontalRangeModel();
FigureCanvas canvas2 = (FigureCanvas) v2.getControl();
canvas.getViewport().setHorizontalRangeModel(sharedRange);
Each viewer contain sufficient large figure to make them show the
scrollbar.
The problem is that the v2 scrollbar only scroll a small part of its
figure and of the one of v2.
I have made a lot of search in the gef threads and did not found a solution
Please help.
Many thanks.

Sami, are both the viewers going to have scrollbars? I am not sure if you
can share range models in that case since each of the two scrollbars would
have to be proportionate to the contents of the two different viewers.
GEF's rulers do something similar in that they share a range model with the
graphical viewer. The difference is that the rulers themselves never show
the scrollbars. You can look at RulerRootEditPart.RulerViewport to see how
we've implemented this.

Thanks Pratick
Actually the 2 viewers have scrollbars but only the second viewer will
have horizontal scrollbar driving the first one.
In that case, is it possible to set the first viewer scrollbar visibility
to never and in that cas how can I get it from the viewer
Many thanks

You can hide one viewer's scrollbar and it will still "be there".
The best approach might be to try to keep the values in sync with a
listener.
