Disable JFrame when a new JFrame is opened
(2 answers)
Closed 10 years ago.
I was wondering if it was possible to disable all other action when a JFrame is opened in Java.
Just like this?
Is there easy code for this?
This has been asked many times and the answer is always the same: use a modal JDialog or JOptionPane (which is a version of a modal JDialog), not another JFrame.
For example, please check out mKorbel's answer here.

For example, if I had checked a JCheckBox when I opened the program, how would I make the it remember the status of the checkbox so that the next time I open up the JFrame, the box stays checked.
I would also like to extend this question to other swing components like radiobuttons, color chooser, etc.
Attempted solution: The only way I can think of it is possibly making a new file so that the program can update and read the status of it and adjust the swing components when opened. However, this is too inefficient. I read online something about cookies but I am not too sure.

How do you add a ActionListener to the close button (not a JButton the button on the top-right)?
See Closing an Application for a discussion on this topic and a couple of solutions.
Basically you need to do two things:
Use the setDefaultCloseOperation(...) of the frame.
Add a WindowListener to the frame

How can I restart a Java application?
i am working on a java program which takes in bunch of values from the user and returns an answer. i have a "clear" button which makes the application ready to for a new set of input. So what i want is that this button should close the frame currently being viewed(create a window closing event and so on) and then call the main() function to create a new instance of my application. How should i do it? I tried this but it closes everything and the new frame doesn't show up:
WindowEvent wev = new WindowEvent(this, WindowEvent.WINDOW_CLOSING);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(wev);
main(newInstance);
and also what does Toolkit do? suggest some readings for that. Thank you.
as per my comments I don't think this is best practise, but it is possible.
