Ethereum. Is there any way to notify about contract creation?

When I publish a new smart contract to the Ethereum blockchain, I want to notify another contract about it. Is there any option to do that? For example, to send transaction automatically when contract reaches the blockchain.

So lets call E your existing contract. Ensure it has a method that we can call notify for instance. When you create your new contract, from the constructor (called when it gets deployed) then call the notify method of E.

No, but Yes.

It wouldn't be possible to notify a contract about any contract created, and I don't see an obvious way to notify about all contracts created by a specific user.

But, there's a way to notify a contract about all instances of a certain species of contract. I suspect this is a reasonable assumption, because the interested contract is probably only interested in a certain type(s) of contract.

You would implement a factory pattern and get it to deploy the instances. The function that does the deployment would be responsible for required notifications.

Hope it helps.
