Custom Figures and Synchronizing the model [message #21590]

Hi,

I have been using GMF and creating custom figures, the custom figures
are made up of images and several label which might or might not be
shown based on some logic that needs to be applied to the model.

I am now trying to work out the cleanest way to add the
synchronization of the model with the figure, I suppose the EditPart
should contain the logic but what is the preferred way to override the
default EditPart?

Cheers

Hello!

You could override refreshVisuals() in generated edit parts to update
figure on model changes.

I have tried this appraoch - however refreshVisuals does seem to get
called when the underlying EMF model changes (such as through editing on
the properties view).

Hello!

Add the following code in ShipEditPart of TaiPan sample. When you
rename a ship to "Avrora" it becomes red.

protected void refreshVisuals() {
super.refreshVisuals();
Ship ship = (Ship) resolveSemanticElement();
if ("Avrora".equals(ship.getName())) { //$NON-NLS-1$
getPrimaryShape().setBackgroundColor(ColorConstants.red);
} else {
getPrimaryShape().setBackgroundColor(null);
}
}

protected void handleNotificationEvent(Notification notification) {
super.handleNotificationEvent(notification);
if
(TaiPanPackage.eINSTANCE.getShip_Name().equals(notification. getFeature())) {
refreshVisuals();
}
}
