Hi,
I would like to add a legend to my figure. The requirement is like the
legend should not move even when we scroll. I am searching for a layer
which stays static and does not move on scroll.
thanks,
Uma Mahesh

Create a legend layer and add your legend figure to it.
Then let the legend figure listen for viewport changes and move itself
accordingly.
Viewport viewPort =
((FigureCanvas)graphicalViewer.getControl()).getViewport();
viewPort.addPropertyChangeListener(new PropertyChangeListener()
{
public void propertyChange(PropertyChangeEvent evt)
{
if(evt.getPropertyName().equals(Viewport.PROPERTY_VIEW_LOCAT ION))
{
//Do your thing here
}
}
});
