我的目标是选择所有以MANI.txt命名的文件，这些文件存在于各自的文件夹中，然后加载表中不同位置的MANI.txt个文件的路径。在我加载表格中的路径后，我习惯选择所需的路径并修改它们
要加载MANI.txt文件需要更多时间，因为它可能会在我的工作区中出现超过30次等，直到加载文件我想在ProgessBar的帮助下向用户发出警报。列表大小已填充我需要禁用ProgressBar。
有人可以帮我解决这个问题吗？

我相信你必须使用SwingWorker来实现这一点，你可以像下面那样使用它，
SwingWorker worker = new SwingWorker()
{
@Override
public object doInBackground() {
GatheringFiles ob = new GatheringFiles();
java.util.List list = ob.returnlist(folder);
return list;
}
@Override
protected void done() {
java.util.List list = (java.util.List)get();
for(int x = 0; x < list.size(); x++)
{
dtm.addRow(new Object[]{new Boolean(false),list.get(x).toString()});
}
JPanel pan = new JPanel();
JScrollPane sp = new JScrollPane(table);
TableColumn tc = table.getColumnModel().getColumn(0);
tc.setCellEditor(table.getDefaultEditor(Boolean.class));
tc.setCellRenderer(table.getDefaultRenderer(Boolean.class));
tc.setHeaderRenderer(new CheckBoxHeader(new MyItemListener()));
but = new JButton("REMOVE");
JFrame f = new JFrame();
pan.add(sp);
but.move(650, 50);
but.addActionListener(this);
pan.add(but);
f.add(pan);
f.setSize(700, 100);
f.pack();
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setVisible(true);
//hide the progress bar
}
}
worker.execute();
//show progress bar
