How to create modal dialog to suspend menu activity until process completes

Question

I have a Swing application with several tabs, buttons, and menu items.
When the user pushes some of the buttons, a background process is kicked off that may take some time to complete.
When the process is finished, I get notification from a socket that the process has completed.
I then display a dialog that notifies the user that the process has completed.
All this is in place.
What I need to do is to block the user from pushing any other buttons, selecting tabs or menu items while the process is in progress.
My thought was to display a modal dialog with a message and no buttons to remove it,
and then have the application dispose the dialog when I get the completion response.
Is there a way to do this with a JOptionPane or some variant or do I need to create a modal dialog from scratch?
Any suggestions?

Answer 1

I was playing around with this a bit and I think it can be done.
In the main class of my application, I have a variable
public JFrame mainFrame;
mainFrame = this.getFrame():
In the page where I want to disable the application, I have the following:
parent.mainFrame.setEnabled(false);
(parent is a reference to the main class)
When I get a response back from the socket, I can set
parent.mainFrame.setEnabled(true);
This seems to do what I want, but the fly in the ointment is that it disables the entire application.
If I don't get a response, then the application is hung.
Can't use the "X" button to close the application.
I think I can work on some refinements from the clues given to make it work.
Thanks for the feedback.
