Hi,
Thanks for suggestion. But I dont have the list box tied to a database. The
items are a vector. And Im using JList. I have already done it with JTable
and it works fine.
The code is something like this:
public void getListCellRenderer([...], boolean isSelected, boolean
cellHasFocus) {
...
}
When I click on the checkbox this method is called 3 times
1. isSelected & cellHasFocus are false for the old item
2. isSelected & cellHasFocus are true for new item (mousePressed)
3. isSelected & cellHasFocus are true for new item (mouseReleased)

(Since both isSelected & cellHasFocus are always same, there is really ONE
variable which represents the current state which is same for both
mousePressed and mouseReleased. So it basically works like an option-list box
not checklist.) And its also called when you switch to another window and
reactivate this and all of them are repainted. This behaviour is reported as
a bug in bug-parade 4129312 but is closed, because its actually not a bug. it
is just the behaviour of UIManager calling its cells makes it not so easy to
code "in a pure object-oriented manner". Iow it is just not sufficient to use
the internal value of the JCheckBox itself to check/uncheck itself. I tried
capturing the mouse-events but it doesnt help. There were a few sites with
exactly the same problem presented but without solution.
