All components are From OP Java beans and therefore call a predefined function
Calls a static method User.buttonPushed().
It is up to the programmer to implement this function in source file...
Note: This is very ‘non object oriented’ but will
satisfy the need to hold all callbacks in a standard place?
This will solve the problem for callbacks, but what if
interaction from the callbacks to the interface is required?
One solution is, again to have a static method which will be
called be every OP bean after it has been constructed. Each
time this method is called, the newly created component
can be remembered and another method can be used to
query remembered elements...
