JOptionPane has methods which take a component as an argument, like this:
Anyway, when the JOptionPane is asking the user if the user wants to save the file, the frame is unusable. I want to do that to a frame. I used frame.setFocusable(false); but it didn't work. Even after I called that method, I was still able to focus on the frame by clicking it.
How can I do it?

open up a modal JDialog, setUndecorated(true), setSize(0,0)
when the frame is the active window, even though you can't access it,
alt-F4 will close the dialog, then you can do whatever you want with the frame.
