Hello all,
I have two graphical viewers of type
org.eclipse.gef.ui.parts.ScrollingGraphicalViewer. These two viewers are
placed in a sash form.

I want the movement of horizontal scrollbars of both viewers to be
synchronized i.e when i move one scrollbar of one viewer, the other
scrollbar of the second viewer should also move.

I tried the following to get the scrollbars instances but i dont know how
to synchronize :

Here firstViewer, secondViewer is of type BDEGraphicalViewer and
BDEGraphicalViewer extends ScrollingGraphicalViewer.
CODE:-
BDEGraphicalViewer baseViewer;
BDEGraphicalViewer targetViewer;

FigureCanvas baseCanvas = firstViewer.getFigureCanvasForViewer();
ScrollBar baseHorizontalScrollBar = baseCanvas.getHorizontalBar();

FigureCanvas targetCanvas = secondViewer.getFigureCanvasForViewer();
ScrollBar targetHorizontalScrollBar = targetCanvas.getHorizontalBar();

Please help me in solving this problem.
Thank you
Best Regards
Shruthi

Use the RangeModel from the scrollbars.
