CEvent

Event description class. It is used to describe components/controls/forms/list items events in packages.

Since release of 9.0.0 this class supports {namespace} placeholder in signature. It is recommended to use it everywhere instead of using hardcoded namespace. This placeholder will be replaced with namespace set to a package entity assigned to event list of this event. So, instead of signature L"mynamespace::CMyWidget *sender" we strongly suggests to use signature L"{namespace}CMyWidget *sender". This will allow to use namespace overwrite feature of Form Builder correctly.

You can find more information in comments below. Overrided methods can be found in corresponding base interface.
