I want to have a clock showing current time and refreshes every second. The code I am using is:
int timeDelay = 1000;
ActionListener time;
time = new ActionListener() {
@Override
public void actionPerformed(ActionEvent evt) {
timeLabel.setText(DateTimeUtil.getTime());
/*timeLabel is a JLabel to display time,
getTime() is samll static methos to return formatted String of current time */
}
};
SwingWorker timeWorker = new SwingWorker() {
@Override
protected Object doInBackground() throws Exception {
new Timer(timeDelay, time).start();
return null;
}
};
timeWorker.execute();
What I want to refresh the timeLabel
text in another thread other than EDT.
Am I doing it correct? Any other better way?
Also for information, i've added timeLabel
to a extended
JPanel
which contains few similar kinds of utilities, and is called in another Main
JFrame
.
You can do this without a SwingWorker, because this is what the Swing Timer is made for.
int timeDelay = 1000;
ActionListener time;
time = new ActionListener() {
@Override
public void actionPerformed(ActionEvent evt) {
timeLabel.setText(DateTimeUtil.getTime());
/* timeLabel is a JLabel to display time,
getTime() is samll static methos to return
formatted String of current time */
}
};
new Timer(timeDelay, time).start();
