下面的代码阻止了我的 UI，我检查了其他帖子，这似乎是一个正确的实现，请让我知道我在这里做错了什么：
public class RecordTest {
public static boolean stopFlag=false;
public static void main(String[] args) {
Display display = Display.getDefault();
Shell shell = new Shell (display);
Label label = new Label (shell, SWT.NONE);
label.setText ("Enter your URL:");
final Text text = new Text (shell, SWT.BORDER);
text.setLayoutData (new RowData (100, SWT.DEFAULT));
Button ok = new Button (shell, SWT.PUSH);
ok.setText ("Start Record");
Thread updateThread = new Thread() {
public void run() {
Display.getDefault().asyncExec(new Recorder(stopFlag));
}
};
// background thread
updateThread.setDaemon(true);
updateThread.start();
ok.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
System.out.println("Start Record");
}
});
Button cancel = new Button (shell, SWT.PUSH);
cancel.setText ("Stop Recording");
cancel.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent e) {
System.out.println("Stop Recording");
stopFlag=true;
}
});
shell.setDefaultButton (cancel);
shell.setLayout (new RowLayout ());
shell.pack ();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}
------------------------------------Recorder.java------------ ------------------------------
public class Recorder implements Runnable {
private boolean stopFlag = false;
public Recorder(boolean stopFlag) {
this.stopFlag = stopFlag;
}
@Override
public void run() {
for (int i = 0; i < 10; i++) {
try {
System.out.println("Waiting ....");
Thread.sleep(3000);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
