Hellos!!!
I have the solution you searching for:
check this code: :D
/**
*
*/
import java.util.Date;
import pt.quantum.padroes.client.services.LoginService;
import pt.quantum.padroes.client.services.LoginServiceAsync;
import pt.quantum.padroes.client.util.LogUtils;
import com.google.gwt.core.client.GWT;
import com.google.gwt.event.shared.HandlerRegistration;
import com.google.gwt.user.client.Event;
import com.google.gwt.user.client.Timer;
import com.google.gwt.user.client.Event.NativePreviewEvent;
import com.google.gwt.user.client.Event.NativePreviewHandler;
import com.google.gwt.user.client.rpc.AsyncCallback;
/**

*/
public class UserIdleTimeOutControl {
Timer mInactivityTimer;
HandlerRegistration mHandlerRegistration;
int mTimeoutInMillis = 5*60000;//thirty minutes max user inactivity
public UserIdleTimeOutControl() {
mInactivityTimer = new Timer() {
@Override
public void run() {
// Logout
mHandlerRegistration.removeHandler();
mInactivityTimer.cancel();
LoginServiceAsync service =
GWT.create(LoginService.class);
service.logout(new AsyncCallback<Void>() {
@Override
public void onFailure(Throwable caught) {
LogUtils.error(caught.getMessage());
LogUtils.loggingOut();
}
@Override
public void onSuccess(Void result) {
LogUtils.info("User idle for "+
(mTimeoutInMillis/1000)/60 +" minutes" +
" logout occur : " + new Date());
LogUtils.loggingOut();
}
});
}
};
mInactivityTimer.schedule(mTimeoutInMillis);
NativePreviewHandler handler;
handler = new NativePreviewHandler() {
@Override
public void onPreviewNativeEvent(NativePreviewEvent event) {
mInactivityTimer.schedule(mTimeoutInMillis);
LogUtils.info("User Event fired occur: " + new Date());
}
};
mHandlerRegistration = Event.addNativePreviewHandler(handler);
}
}
Basically it listens all the interface events and if no event occurs in X
minutes session invalidate and logout will be called.
Is something like this you looking for ?
Hope it helps! :
