Netbeans checkbox handling ..stuck

Question

hi !
I am using netbeans to design a gui and stuck at a place
I want to execute a command say "foobar -t - a filename -o filename "
i have created a string buffer that stores "foobar ". I want that on checking a checkbox positive the options like "-t" gets appended to the original foobar . how do i make it .
how do i use the method to do this : -
private void abcItemStateChanged(java.awt.event.ItemEvent evt) { (this is created once i add event listener to a check box )
here i handle the checkbox (SELECTED or DESELECTED)
abc is the name of checkbox . please help , even pointing to some doc will also do .

I doubt that you will have to worry about any checkbox state changed method here as you're not going to be calling your command string when the checkbox is checked or unchecked, correct? The most important question in my mind is: what will initiate the construction and calling of your command string? My guess is that you have a standard JButton (not a JCheckBox) that when clicked will tell the program to gather the information in the JTextFields and JCheckBoxes (oh, btw, I'm assuming that you're using Swing here, not AWT, correct?), create your command String and somehow use the string to issue your command. It is in this method where you need to get the state of the checkbox and use that state in constructing your String (probably by using a StringBuilder). You get the JCheckBox state simply by calling the isSelected() method on the check box.
If this makes no sense, then sorry, and perhaps I didn't fully understand the question. If so, please provide more information.
Good luck.
