however, the abstract class gives me an error.Please carefully report the full details of this error. Forum members are unlikely to know what a "GBP*" is.
What am I doing wrong?not telling us what error you're getting exactly
The error I am getting is "missing method body, or declare abstract". Declaring the GBPanel gives me an error, but without it, its demanding abstract.

The error I am getting is "missing method body, or declare abstract".no, it isn't. it's also telling you which method body is missing. when a method is declared as abstract in a superclass of your class, you're going to have to implement that method in your class.
