DateTime?は日付・時刻の入出力を行えるウィジェットです

date = new DateTime(composite, SWT.DATE); // 日付ウィジェットの場合
time = new DateTime(composite, SWT.TIME); // 時刻ウィジェットの場合

DateTime?のウィジェットに時刻や日付データを反映させるサンプルです。

public static void str2TimeWidget(DateTime dateTime, String timeStr,
    String[] pattern) {
  String[] patternTmp = new String[] { "HHmm", "HH:mm" };
  if (pattern != null) {
    patternTmp = pattern;
  }
  try {
    Date parseDate = DateUtils.parseDate(timeStr, patternTmp);
    Calendar cal = Calendar.getInstance();
    cal.setTime(parseDate);
    int hours = cal.get(Calendar.HOUR_OF_DAY);
    int minutes = cal.get(Calendar.MINUTE);
    int seconds = cal.get(Calendar.SECOND);

    dateTime.setTime(hours, minutes, seconds);
  } catch (ParseException e) {
    e.printStackTrace();
    dateTime.setTime(0, 0, 0);
  }
