Input type Check box

Hi,

Please see the attached document.
On checking the box "Order Qty from Net Qty", I would need the "Order Quantity" text box to be filled with the values.

I have also included the few lines of that function, let me know how it works?

Thanks,
Jeeva

Look at the JCheckBox API and see what add listener methods it provides (check parent classes as well). You need to add a listener that responds to the value being modified.
