Your EditPart should be notified when the location in the model changes.
Your EditPart can then revalidate the figure (which will cause a layout to
occur). If you are using constraints, then simply setting the layout
constraint on the parent EditPart will do the trick. This should already be
happening in refreshVisuals().

Thanks Pratik !
That's good. But I encountered another problem. The graphical include

lines. The changes could be response completely util i refresh the screen

(Example: minisize,then maximum). why ?

Many thanks.

Hmm, not sure. Try invoking figure.repaint(). But this should already be
happening during revalidation if the location's changed.
