Thanks. I think I'm beginning to hate my Java instructor. He teaches
wrong! I now see how I should have designed all my dialogs
substantially different. I have hours of recoding to do. :(

I'll figure this out a bit more and then I guess it's another night
down the tubes.

Assuming you are using javax.swing.JFileChooser, and not a custom
written component, I think you may be using the component incorrectly.
Usually you would do something like:

                JFileChooser chooser = new JFileChooser("C:\\");
                chooser.setFileFilter(new yourCustomFilter());
                int returnVal =
chooser.showSaveDialog(getRootPane().getContentPane());
                if(returnVal == JFileChooser.APPROVE_OPTION)
                {
                    String path =
chooser.getSelectedFile().getAbsolutePath();
                    ....//save data etc

It's the calling of showSaveDialog() that causes it to be displayed
modally.

I have two JFrames. The main GUI and then a JFileChooser frame.

I want the JFilechooser frame to let the GUI know whether the file has
been written to disk or not.

So I tried

  strStatusMsg = chooserFrame.showFrame(file);

and then method showFrame in the JFileChooser Frame

  public String showFrame(String fileName) {
          setVisible(true);
          return strStatusMsg;
  }

This doesn't work, the code doesn't block on the method invocation, it
passes right through to the return statement. When I run the file save
again, then obviously it picks up the status from the previous
invocation and passes it back.

Any hints on how I can let the main method know the file has been
written? I don't really want to create an object that gets passed to
the filechooser message and one of the objects within that object is a
status string. I somehow think that is also not the correct approach.
