    Arrow Application Gui Issue

    Hello all,
    i have created a application gui that use a SwingWorker to update a JTextArea and JTable into a loop. This works fine and the swing components are updated in real-time. My issues started when the frame is iconized and the process continues in background mode. When i deiconized the frame, some lines of my text aren't visible or some JTable's columns data aren't updated and i have to pass with mouse on the JTextArea or click on the JTable's columns to refresh them. I've tried to use a WindowsStateListener to catch when the frame is decoinized and to revalidate and repaint it but this didn't solve my problem.

    Do you have some ideas?

    Thanks a lot and sorry for my English

    Swing is not thread safe. Updating Swing components should be done on the EDT.
    If you don't understand my answer, don't ignore it, ask a question.

    I've tried to execute updating into java.awt.EventQueue.invokeLater or into SwingUtilities.invokeLater methods but it still doesn't working.

    Do you have other ideas?

    Thanks a lot

    Not sure, but your description - iconized vs deiconized - gives the impression that the components are changing in which case you may need to revalidate() the container.

    Thanks for your response. I execute a process that write in a jtextArea and enable and disable some buttons but don't add or remove components to the JFrame. Now i'm trying to use a Windows Listener to catch when frame is deiconized and then revalide and repaint my frame. I'll alert you if this solve my problems.

    Thank you!

    --- Update ---

    I've solved problem with use revalidate and repaint into a Windows Listener.
    Thanks a lot.

    Regards
