How can one obtain the state of a JCheckbox? I want to know if it is
checked or unchecked, not when it is clicked.
Thanks
Allan

Follow the link "How to Use Buttons, Check Boxes, and Radio Buttons":

Below the heading "Implementing the Button's Functionality" you find
a reference to "isSelected":

Good luck

Well when it's clicked just register it into some variable like boolean.
example, set it to non-checked at start:
...if clicked code...
...change(cb_clicked); where cb_cliked is boolean

since boolean is ordered type with 2 values I assume you can somehow switch
between true and false with some method that increases or decreases a value.
I don't exactly know what it is in Java.
