🚀 go-pugleaf

I am using a JdbNavList, put on a scrollpane.
The content of the list changes run-time, using a
parameterized query. Vertical scrollbar seems to
work fine. Horizontal scrollbar does not work.
I have different problems for two list:
- In one list, the items of the list are long, and the
scrollbar does not show.
- In the other list, the items are very short, but the
scrollbar insists on showing.
I have noticed that changing the "preferred size"
attribute of the list can make a difference, but not the
kind of difference I want (it is not dependent on the
size of the actual items). I have tried calling validate,
or revalidate on the scrollpane when the query is executed
but that did not make a difference.

Any ideas?

JScrollPane     Example_ScrollPane  = new JScrollPane();
JdbNavList     Example_dbNavList  = new JdbNavList();
contentPane.add(Example_ScrollPane, null);
Example_ScrollPane.getViewport().add(Example_dbNavList, null);

Best wishes,
