Hi Guys,

Is there a way to update manually/pragmatically the RulerFigure of the diagram when there is changes in the underlying EObject?

I have created a EMF based application and used Graphiti for my graphical editor. I have implemented custom units for the rulers in my graphical editor. I need to update the ruler based on the new units specified on the underlying EObject.

Is there a way to trigger the updates on RulerFigure?

Many Thanks,
Ken

Hi All,

I have a work around in my problem. In the extended RulerComposite and use it in my GraphicalEditor. Inside the RulerComposite create a public method that contains the following:

public void updateRulers() {
	setRuler((RulerProvider) diagramViewer.getProperty(RulerProvider.PROPERTY_HORIZONTAL_RULER), PositionConstants.NORTH);
	setRuler((RulerProvider) diagramViewer.getProperty(RulerProvider.PROPERTY_VERTICAL_RULER), PositionConstants.WEST);
}

With this, we can call and trigger the updates on ruler whenever we want it.
If there is another way, please do tell in this thread.

Thanks,
Ken
