Add connection without palette [message #1139320]

Hello everybody,

I have a custom feature that rightclicking on an object, another one is created at its right (both objects of the same type, called PositivePattern). There are like 20 units of space between them and I want them to be connected.

The thing is that the conection must be created when the object is created so I cannot use the palette and bind them. I do it a the CustomFeature class.

This is what I have (All the PositivePattern have an anchor created in the add method):

// get Classes which should be connected
Pattern source = (Pattern) bo;
Pattern target = pp;

AddConnectionContext addContext = new AddConnectionContext(cs.getAnchors().get(0), cs2.getAnchors().get(0)); //Being cs and cs2 the containers of the 2 objects

Connection newConnection = (Connection) getFeatureProvider().addIfPossible(addContext);

addIfPossible returns null so I guess that the created context (addContext) is not a valid one. Someone knows how to proceed?

Thanks in advance.

Víctor.

Victor,

I think you need to implement an IAddFeature that recognized the case
where you provide two anchors and returns true from the
canAdd(IAddContext) method. This will let the feature provider find and
use it in its addIfPossible method.
