Resizing using DelegatingLayout [message #208324]

Hi
I don't know how to move and resize my figure using DelegatingLayout.
Will I writer a DelegatingLayoutEditPolicy as a editpolicy?
I have to use Delegating Layout, since I want to resize my labels
attached to a polylineconnection.
thanks in advance.
Ivo

You can refer the XYLayoutEditPolicy to construct the
DelegatingLayoutEditPolicy

public class DelegatingLocatorImpl implements DelegatingLocator{
private Rectangle rect = null;

public DelegatingLocatorImpl(Rectangle rect){
this.rect = rect;
}
public Rectangle getConstraint(){
return rect;
}

public void relocate(IFigure target){
target.setBounds(rect);
}
}

public interface DelegatingLocator extends Locator{
public Rectangle getConstraint();
}

Inside your editpart's refreshVisuals(){
DelegatingLocator locator = new DelegatingLocatorImpl(new Rectangle());
setLayoutConstraint(locator,this);
}

Inside the DelegatingLayoutEditPolicy
public Rectangle getConstraintsFor(){
return ((DelegaingLocator)constraint).getConstraint();
}
