在多任务应用程序中管理GUI和EDT

在多任务应用程序中管理GUI和EDT

正如其他人所建议的，最好的方法是使用

SwingWorker

。

SwingWorker

属性是可监听的，并且总是在EDT中调用监听器，因此，您可以执行以下 *** 作：

public class ArchivingWorker extends SwingWorker<Void, Void> {    JProgressBar progressBar = null;    // Other members here...    ...    public ArchivingWorker(...) {        // Any specific initialization here (in EDT)        addPropertyChangeListener(new PropertyChangeListener() { @Override void propertyChange(PropertyChangeEvent e) {     if (    "state".equals(e.getPropertyName())         &&  e.getNewValue() == Statevalue.STARTED) {         // Background thread has just started, show a progress dialog here         progressBar = new JProgressBar();         ...     }     else if ("progress".equals(e.getPropertyName())) {         // Update progress bar here with e.getNewValue()         ...     } }        });    }    @Override protected Void doInBackground() {        // Archiving process here and update progress from time to time        setProgress(progress);        return null;    }    @Override protected void done() {        // Ensure that archiving process worked correctly (no exception)        try { get();        } catch (Exception e) { // Handle exception (user feedback or whatever)        } finally { // Close progress dialog ...        }    }}

然后，您可以

ArchivingWorker

根据需要使用：

ArchivngWorker worker = new ArchivingWorker(...);worker.execute();
