Hello Michel,

In the code you have posted, the class Test descends from 'C'ontainer,
while the parent class you try to
use is 'K'ontainer. I do not know if this is your problem, but it could
be if you have cutted and pasted the code.

But I also have experienced that JBuilder cannot access subcomponents
from the parent class, because JBuilder analyses the code in the
memberfunction JBInit to visually access components that are locally
declared in the class. A possible workaround would be to give access to
your components through getters and setters, wich would be a more
correct OO approach to the problem.

Hope this helped,

Wim Van Leuven.
