Wolf,
This is a simple extension to SwixML to support CardLayout.
I attached the modified LayoutConverter.java and ConstraintsConverter.java
from the 4th beta release. (All changes [3] are labeled with: //SL )
This is a minimal support for CardLayout which might be enough
considering the low demand for this feature.
You access the card layout manager of a component installed by SwixML
in the good old way :) :
(CardLayout)((Container)swingEngine.find("id_of_my_CLed_comp")).getLayout()
Best wishes,
Levente
