@cheng5230 I have added the FabricDelegateImpl into the porting layer in this branch.

This should be flexible for user to include their codes when different fabric event happens.
For your reference, I have added PostEvent() for CommissiongWindowOpened, you can check if the implementation has meet your needs. But when officially added into the repo, the example will be removed.

Thank you.
