I am using a zoomslider in graphiti using the following code piece:

import org.eclipse.gef.GraphicalViewer;
import org.eclipse.gef.editparts.ZoomManager;
import org.eclipse.graphiti.features.IFeatureProvider;
import org.eclipse.graphiti.ui.internal.util.gef.ScalableRootEditPartAnimated;

zoomSlider = new ZoomSlider(bottomToolbar, SWT.LEFT_TO_RIGHT);
zoomSlider.addSliderListener(new SliderAdapter() {
public void sliderMoving(Object source, int value) {
GraphicalViewer graphicalViewer = (GraphicalViewer) iSelectionProvider;
ScrollingGraphicalViewer viewer = (ScrollingGraphicalViewer) graphicalViewer;
ScalableRootEditPartAnimated editPart = (ScalableRootEditPartAnimated) viewer.getRootEditPart();
ZoomManager zoomManager = editPart.getZoomManager();
zoomManager.setZoom((((double) zoomSlider.getZoomDiscreteValues()[value]) / 100));

But the graphiti view flickers a lot while i move the zoom slider very fast and it does not provide the correct zoom value at times, if the zoom slider reading is 1% the actual zoom level of the view is more than 150%.
Is there any way to control this or any other zoomSlider is there which is supported by graphiti and it works smmothly?

Kind Regards,
Mithu Deb

That looks a lot like bug 414437, that is solved in master.

Which version of graphiti are you using?
