I haven't checked if it is actually possible to do what you want, but why do you want to do that? ;-)

Having JCheckboxes inside a JList seems odd to me because both involve selection.

You could directly select items on the JList and retrieve the selection via getSelectedValues(). Or you could put JCheckboxes in a JPanel.

Thankz for ur attention

Actually i want to retrieve data from Database to List & user can be able to select items from that list. Then according to selected values database will be update. Yeah..

I know that i can do this using only JList, but I think its not much user friendly. If i can add checkboxes to list its better.

You should implementy custom CellRenderer and CellEditor which will return JCheckBox as rendered component and assign them in the JList.regards,Stas

Google for "implements CellRenderer extends JCheckBox" and you will find plenty of examples.Regards,Stas

Use a JTable, it already provides support for check boxes.

Let me start of by saying that I agree with camickr in that a JTable would both be the best and simplest solution. Why reinvent the wheel?

However, it can be done with a custom renderer if you want practice in that sort of thing. A working example can be downloaded from the website of Manning's excellent Swing book:

Scroll down to the Source Code section and download the Second Edition Samples. The example you're looking for should be Chapter 10\4.

I agree with camickr. You can use a JTable or a JPanel to put your checkboxes into. It depends on what your GUI is supposed to do. Without further information, the amount of advice we can give you is limited.
