[Newbies] Handling events on NCAAConnectorMorph subclass

Hi,

I am using package Connectors.

I made my own connectors subclassing NCAAConnectorMorph [say it is called MyCon]

Now, I would like the aMyCon to change its color to black when it is connected to other 2 morphs and be orange when it is not fully connected.

I saw there is NCAAEventsHandler with stateConnected and stateDisconnected but I don't understand how i can use these two events.

I tried defining inside the class MyCon methods like these, copying what I do for mouse events: ------------ handlesStateConnected: evt   ^ true

stateConnected: evt     self color: Color black ------------

It does not work.

How should I do ? I don't find an example.

Are NCAAEventsHandler events recognized by NCAAConnectorMorph ?

I would like my event handler to add up to what the default event handler does, not substituting it.

bye Nicola
