StatusBarController with EventQueues mechanism
Hi...
@terrytornado
Hope your problem is resolved.. but my problem is still there and I thought that you can help me to get out of this problem.
actually I had multiple events to publish one by one as per user selection for eg: user select Season, Service, DateFrom and DateTo and then clicks on the refresh button.
When the refresh button is clicked I had used the above logic to get all the datas using the below mentioned code
public void onClick$ref(Event event){
if(lbox_service.getSelectedIndex() != 0 || lbox_season.getSelectedIndex() != 0)
{
if(lbox_service.getSelectedIndex() == 0)
{
setService_id("0");
}
else
{
setService_id(lbox_service.getSelectedItem().getValue().toString());
}
if(lbox_season.getSelectedIndex() == 0)
{
setSeason_id("0");
}
else
{
setSeason_id(lbox_season.getSelectedItem().getValue().toString());
}
System.out.println("Service Index 11 : "+ lbox_service.getSelectedIndex());
System.out.println("Season Index 11 : "+ lbox_season.getSelectedIndex());
EventQueue evtQ = EventQueues.lookup("myEventQueue", EventQueues.APPLICATION, true);
//evtQ.publish(new Event("service_id", self, lbox_service.getSelectedItem().getValue().toString()));
//evtQ.publish(new Event("season_id", self, lbox_season.getSelectedItem().getValue().toString()));
evtQ.publish(new Event("service_id", self, getService_id()));
evtQ.publish(new Event("season_id", self, getSeason_id()));
//evtQ.publish(new Event("onClickRef", null, lbox_service.getSelectedItem().getValue().toString()));
//evtQ.publish(new Event("onClickRef", null, lbox_season.getSelectedItem().getValue().toString()));
/*.publish(new Event("onClickRef", null, lbox_service.getSelectedItem().getValue().toString()));
EventQueues.lookup("myEventQu", EventQueues.DESKTOP, true)
.publish(new Event("onClickRef", null, lbox_season.getSelectedItem().getValue().toString()));*/
}
else
{
setService_id("0");
setSeason_id("0");
EventQueue evtQ = EventQueues.lookup("myEventQueue", EventQueues.APPLICATION, true);
evtQ.publish(new Event("service_id", self, getService_id()));
evtQ.publish(new Event("season_id", self, getSeason_id()));
System.out.println("Service Index : "+ lbox_service.getSelectedIndex());
System.out.println("Season Index : "+ lbox_season.getSelectedIndex());
}
}
now i had publish all my value and after that my new Controller run that will subscribe those published values. using the below code
public void doAfterCompose(Component comp) throws Exception {
super.doAfterCompose(comp);
<b > EventQueues.lookup("myEventQueue", EventQueues.APPLICATION, true)</b>
.subscribe(new EventListener() {
public void onEvent(Event event) throws Exception {
/*String service = (String) event.getData();
logger.info("Servive $$$$$$$$$ " + service);
//String season = (String) event.getData();
//logger.info("Season $$$$$$$$$ " + season);
*/
if("service_id".equals(event.getName())) {
setService_id((String) event.getData());
baseController.setFilter_bar(true);
System.out.println("Service Id :" +event.getData());
}
else if("season_id".equals(event.getName())) {
setSeason_id((String) event.getData());
baseController.setFilter_bar(true);
System.out.println("Season Id :" +event.getData());
}
/*setService_id((String) event.getData());
setSeason_id((String) event.getData());*/
/*if("season_id".equals(event.getName())){
setSeason_id((String) event.getData());
}else
{
setSeason_id("0");
}*/
System.out.println("Filter bar :" +baseController.isFilter_bar());
if(baseController.isFilter_bar() == true)
{
String dateFrom = "";
String dateTo = "";
String order = "2";
List TDRetailers = verificationStoreHibernateDao.getTraditionalRetailers(getService_id(), getSeason_id(), dateFrom, dateTo, order);
//VerificationStoreHibernateDao storeHibernateDao = new VerificationStoreHibernateDao();
//List TDRetailers = this.verificationStoreHibernateDao.getTraditionalRetailers(service_id);
//ListModel listModel = this.retailers.getModel();
ListModelList listModelList = (ListModelList) retailer.getModel();
listModelList.clear();
listModelList.addAll(TDRetailers);
baseController.setFilter_bar(true);
}
}
});
}
but actully my problem is with running the query and with getting those published values. Based on them I will be able to run my Traditional getTraditionalRetailers queries.
My problem is
1. how to publish multiple events values. Is it the right way that I had done.
2.as I had done separate publish, everytime I publish new value The query runs, the result is that i had mutiple time query execution. for example If i will publish two values the queries run's for the two times and if I publish three values the query executes for three time.
I don't know what is their problem. .
help me to solve my error..
Look here.
Hi all,
I'm worry about my old statusBar and how i access it to actualize the values. So i spend a little time for do it now with the new EventQueues mechanism that 's shipped with the zk 5.x versions.
You can read and copy the codes from http://www.forsthaus.de/blog/?p=515.
Have fun with it.
best
Stephan
