Copy GMF diagram coordinates to model [message #56001]

Hi!

I have a figure (Field) in a compartment, when the user set its
position, it gets x and y values in the view. So i want that the
corresponding object in the model (also Field :) ) get its values for x
and y from the view coordinates.
Must i implement a move-listener for the figure?
Any idea is welcome ...

regards
Jens

Jens,

Do you have your own editpart for this model element? Why don't you
just listen to changes to the location in the view and then update your
element? Check out ShapeEditPart.handleNotificationEvent().

Regards,
Cherie

Hi Jens,

Right now I've got a very similar problem to the one you posted in the
newsgroup. I'm glad you could manage the problem and I wonder if you
could provide some codesnipets for me?
I'd appreciate your help very much as it could help me save some time
trying to resolve the problem on my own.

Thanks in advance
Alex

Hi Alex,

here you have a snippet of my code...

This is the method from my
<DomainModel-Name>.diagram.edit.parts.FieldEditPart

/**
* @generated not
*/
protected void handleNotificationEvent(Notification arg0) {
// SET was the type i need
if (arg0.getEventType() == Notification.SET) {
// the notifier sends his new Bounds ...
if (arg0.getNotifier() instanceof BoundsImpl) {
BoundsImpl notifier = (BoundsImpl) arg0.getNotifier();
// for my special coordinate mapping i also need the node,
// so i save it in this variable ...
NodeImpl node = (NodeImpl) this.getModel();
// get the corresponding FieldLabel Object from the model
FieldLabel model = (FieldLabel) node.getElement();

if (arg0.getFeature() instanceof EAttributeImpl) {
// Get the attribute that has changed
EAttributeImpl attribute =
(EAttributeImpl) arg0.getFeature();
// set the values for x and y in the model
if (attribute.getName().equals("x")) {
model.setX(notifier.getX());
} else if (attribute.getName().equals("y")) {
model.setY(notifier.getY());
}
}
}
}
}

So everytime the bounds change the information is stored in the model.
If the user moves the FieldFigure or if the values are changed in the
editor doesn't matter
