Add an event to an implemented class

Hello everyone
Xojo

I am grateful for the interest and scope of the following:

I have a custom class of a text field with several GotFocus, KeyDown and other events, now I need to add the LostFocus event to the class.
you have already created objects with this class and the created objets some have code implemented in the LostFocus event

The LostFocus event code added in the class is as follows:
RaiseEvent LostFocus

But it shows an error that the LostFocus is implemented

Is there any way to solve this problem?

all your answers will be greatly appreciated
Cordially

You should be able to create a new custom event handler and name it LostFocus

Thank you so much
Kevin Gale

I had forgotten to create the LostFocus in Event Definitions so that it can be inherited with that same name in the object

Cordially,

Raul
