[gef-dev] Re: Resizing figures.

[michaelsun@xxxxxxxxxx]

hello Bharath

After I make the following changes, it works, though I
am not familiar with emf, ecore classes
such as EAttribute, EClass, and the ENotificationImpl.
I try using PropertyChangeListener as my ModelListener
to replace Adapter. 


1. modify
NetworkXYLayoutEditPolicy.createChildEditPolicy method 

protected EditPolicy createChildEditPolicy(EditPart
child) {
		
		
		NetworkNodeEditPart childEditPart =
(NetworkNodeEditPart) child;

		NodeFigure rectangle = (NodeFigure)
childEditPart.getFigure();
		
		return new ResizableEditPolicy();

}

2. In the interface Node.java,  add two new methods

Dimension getSize();
	
void setSize(Dimension s);

3. In NodeImpl.java add
protected Dimension size_EDEFAULT = new
Dimension(-1,-1);
protected Dimension size=size_EDEFAULT;


public Dimension getSize() {
		return size;
}

public void setSize(Dimension dimension) {
		
		Dimension oldDimension = dimension;
		size = dimension;
		if (eNotificationRequired())
			eNotify(new ENotificationImpl(this,
Notification.SET, NetworkPackage.NODE_SIZE,
oldDimension, size));
		
}

and it is easy for you to modify other methods, for
example, only add more "case return" following the
method pattern.


4. In NetworkPackage.java, add something like
int NODE_SIZE=11; //randomly choose the int
EClass getSize();

5. In NetworkPackageImpl.java, add
public EClass getSize(){
		return (EClass)nodeEClass.getEReferences().get(11);
}

6. In SetConstrainCommand.java, add
two new fields:
private Dimension newSize;
private Dimension oldSize;

in execute() add part.setSize(newSize),
also add it to other methods.

7. In NetworkNodeEditPart.java, modify
refreshVisuals(), replace 
Dimension size = new Dimension(-1,-1);
with Dimension size = getNetworkNode().getSize();
