Actually, I think you want to use getMoveDelta() and use it in relation to
the figure's current location.

Hi,Pratik,

This method is helpful to me, and I can get the relative location.
And one more question is, how to get the figure which is moving.
Here is part of code in policy for your reference, wish your suggestion.

/* (non-Javadoc)
* @see
org.eclipse.gef.editpolicies.LayoutEditPolicy#getMoveChildre nCommand(org.ecl
ipse.gef.Request)
*/
protected Command getMoveChildrenCommand(Request req) {

// System.out.println(this.getTargetEditPart(req));//it prints null

if(req instanceof ChangeBoundsRequest) {
Point point = ((ChangeBoundsRequest)req).getMoveDelta();
System.out.println(point);
}
return super.getMoveChildrenCommand(req);
}

Ok, I have get the moving figure now.

((ChangeBoundsRequest)req).getEditParts() is enough, it will get the
editparts which invoke this request.

I think it will get all the editparts just now.
