I have checkboxes. I have a buttongroup. When I click on the option “All Checkboxes,” I want all checkboxes in the button group to be made unselectable (grayed out) (Except the “All Checkboxes” one which is selected.) How do I this?

Also, how can I add an item/set the items to a Combo Box using NetBeans?

    I have checkboxes. I have a buttongroup. When I click on the option “All Checkboxes,” I want all checkboxes in the button group to be made unselectable (grayed out) (Except the “All Checkboxes” one which is selected.) How do I this?

    A ButtonGroup cannot be used to grey-out (functionally and visibly disable) a JCheckBox. Better to put them in a List<JCheckBox> and in the ActionListener for “All CheckBoxes” iterate through calling setEnabled(true/false) on the items in the list, the parameter depending on the state of the “All Checkboxes” JCheckBox.

    Also, how can I add an item/set the items to a Combo Box using NetBeans?

    I have no idea how to do this “using NetBeans”, but using Swing you simply get the JComboBox’s model, usually a DefaultComboBoxModel, and add items to it.
