That has no bearing on the way the JDialog constructor accesses the 
JCheckBox. It would be the same whether a JMenuUtem or JButton or 
Exception handler invoked the JDialog constructor.

The code that creates the dialog refers to checkbox
    p.add(new JLabel(checkbox.isSelected() ? "Fatso" : "Beanpole"));
If that's not the sort of thing you want to do, you should explain in 
more detail.

You can do it that way too.
   if (frame.checkbox.isSelected()) {
      blah blah blah;
   }

It's a question of the scope of either the variable which refers to the 
JFrame instance or the scope of the variable that refers to the 
JCheckBox instance. Or both.

Alternatively you could pass a reference to either of these variables 
into the method or constructor that creates the JDialog instance.

I'd prefer something like ...

class Whatever {
    Whatever() {
        ...
        JButton dialogInvokingButton = new JButton("Click me");
        dialogInvokingButton.addActionListener(this);
        ...
        frame.setVisible(true);
    }

    void actionPerformed(ActionEvent e) {
        new DialogCreatingClass(frame, checkbox.isSelected());
    }
}

class DialogCreatingClass {
     DialogCreatingClass(JFrame frame, boolean likesFries) {
         JDialog d = new JDialog(frame, ...);
         ...
         if (likesFries)
         ...
         d.setVisible(true);
     }
}

There's zillions of ways to do what you describe.

What I posted before was an SSCCE (Google will explain). Maybe you 
should construct one that better illustrates your question and post it.
