I am trying to implement a style of zoom for my zest viewer.

In actual fact, I am merely expanding the graph so that the nodes are not
so close to each other.

I cannot manage to ever retain the view location after my zoom (the zoom
is actually a layout).

I tried getting the preffered size of the graph control:
org.eclipse.swt.graphics.Point preferredSize =
graphViewer.getGraphControl().computeSize(SWT.DEFAULT,
SWT.DEFAULT);

and then either setting the view location:

getZoomManager().setViewLocation()

or

playing with the bars directly:

getGraphControl().getVerticalBar().setSelection((preferredSi ze.y));

but nothing works.

Does anyone know what I might be doing wrong?

thanks
