Display ports that are not contained by object [message #1000228]

Hi,

I have a meta-model which looks the following:

+------+      type +-----------+
| Type |<----------| Prototype |
+------+           +-----------+
   <>
    |
    |
+-------+
+ Port  +
+-------+

The type contains a set of Ports. A Prototype references a type.

Type:
In GMF Type is top-node-reference and Port is a child reference.

Prototype:
In GMF Prototye is a top-node-reference.

What I want to do now is the following. I create a type (TypeA) with some ports. Then I create a prototype and select the type (TypeA) in the properties. Now all the ports which are on TypeA shall be displayed on the Prototype as well.

Is this possible with GMF ?!

Hi,

in your edit part of prototype you could overwrite handleNotification and change the figure to look like what you intend to. This could give you a starting point: http://wiki.eclipse.org/GMF/Tips#Making_figures_sensitive_to_attributes_of_semantic_elements. Once you decide to modify generated code I would recommend you to place this code in a custom template which can save you a lot of work. Alternatively you could use the extension points of the GMF Runtime.

Hi Ralph,
thanks for you answer. I was trying sth. similar today:

PrototypeEditPart

protected void handleNotificationEvent(Notification notification) {
PortEditPart port = new PortEditPart(getDiagramView());
addChildVisual(port);
addFixedChild(port);

However, now the port is not attached to the border, instead he is inside the port figure and too big.

Any ideas?

Hi,

you could try to reuse the generated code that is already used for the other figure. Did you try to copy this code over?
