    Default Problem visualize Jframe contents during the execution of an ActionPerformed

    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

    Sounds like you're blocking the EDT with a while(true) or a long-running task. Instead, use a separate Thread or a Swing Timer.

    Sorry for the cross posting Kevin
    The problem is exactly that the thread is blocked into a while(true).
    I still have the problem, and i try to explain it better.
    Maybe you could have a look.
