Absolute position of a Point [message #176769]

Hi all,

I just begin to work with draw2d.geometry and I need some help:

In a sequence diagram, I know the relative position of a Point doing this:

GraphConnector connector = (GraphConnector) ((GraphEdge)
childElement).getAnchor().get(numanchor);
org.eclipse.draw2d.geometry.Point pos = new Point(connector.getPosition());

I would like to know the absolute position of this point in the diagram.
Thanks for your help.

Regards,

Emilien

Hi Emilien,

IFigure defines methods translateToAbsolute(Translatable) and
translateToRelative(Translatable).

Translating a point to absolute coordinates should be easy if you know
the figure whose coordinate system in used by your point. Typically it
takes several guesses to get the correct transformation :)

Best regards,
Boris
