Problem visualize Jframe contents during the execution of an ActionPerformed

[gtotto]

Hi guys,

I'm new on the forum and i hope to be in the right section.
I'm already sorry for the bad english i will use: i hope you will understand the question.

I have a problem. :)

I have a Jframe "MAIN: with a Jbutton "START" which is related to an action.
The action should create a new JFrame "SECOND" with a Jmenu, a text Area showing a particular String and, after that, execute a procedure "LISTEN" which will monitor a directory.

The problem is that the program creates the Frame "SECOND" , but i cannot see and interact with the contents as long the procedure "LISTEN" is not terminated.
Considering that the procedure never ends without any signal.

How can I fix it?
Because i would like to have the Frame "SECOND" with an "Exit" Button in a "File" Jmenu in order to send a signal and interrupt the procedure LISTEN and eventually terminate the program.

Thank you in advance for the patience and the help.

Cheers

gtotto

OK guys, sorry for the "cross-posting" and thank for the help.

I've still serious problem, even if i have understood a little the theory, i cannot implement the thing using the swing worker thread.

Normally I have a button.

I add the button a new ActionListener.

The ActionEvent related should does :

1- Open a new Frame with some features and i would like to associate this operation to a Swing Worker, because i need user is allowed to interact with it,

in this case for example i don't understand where should i define the frame. In "doinBackground" or in the method "done()"?

2- Another Frame where is running a procedure, which is cycling into a while(true).

How should i do?

Could someone suggest me the structure?

Thank you,
