Java loading gif freeze while processing data?

Question

I call a method which lists all the files in a directory, and adds them to a JTable:

    addFilesWithSubsButton.addActionListener(new ActionListener() {
             


        

Answer 1

My guess would be that your addFilesWithSubs2-Method is blocking the UI thread. If you have long running tasks, than you have to execute them in a separate thread e.g. SwingWorker
