GWT DynaTable Problem
Hi All!
I'm new to GWT and I have a little problem. I'm trying to modify one
of Google example apps - the dynamic table witch a school schedule.
The data in the example is generated randomly. I modified it so the
data in the table is from the JDO database. What I want to do is to
modify the code, so the rows in the table will be updated when there
is a change in the database, beacause right now they aren't updating.
Here's the server side application code:
public class RankTableServiceImpl extends RemoteServiceServlet
implements
RankTableService {
private static final Person[] NO_PEOPLE = new Person[0];
private static final int MAX_PEOPLE = 100;
private final List people = new ArrayList();
Query query;
List results;
PersistenceManager pm = PMF.get().getPersistenceManager();
public RankTableServiceImpl() {
generateUserList();
}
public Person[] getPeople(int startIndex, int maxCount) {
int peopleCount = people.size();
int start = startIndex;
if (start >= peopleCount) {
return NO_PEOPLE;
}
int end = Math.min(startIndex + maxCount, peopleCount);
if (start == end) {
return NO_PEOPLE;
}
int resultCount = end - start;
Person[] results = new Person[resultCount];
for (int from = start, to = 0; to < resultCount; ++from, ++to) {
results[to] = people.get(from);
}
return results;
}
@Override
protected void onAfterResponseSerialized(String serializedResponse)
{
System.out.println(serializedResponse);
}
private void generateUserList() {
int i = 0;
String login;
String money;
User element;
int cash;
query = pm.newQuery(User.class);
results = (List) query.execute();
Iterator itr = results.iterator();
Collections.sort(results, new MoneyComparator());
while (i != results.size())
{
if (i == MAX_PEOPLE) break;
Person person = new Person();
person.setPosition(Integer.toString(i+1));
if(itr.hasNext())
{
element = itr.next();
login = element.getLogin();
cash = element.getMoney();
money = Integer.toString(cash);
}
person.setLogin(login);
person.setMoney(money);
people.add(person);
i++;
}
}
}
and the client side applicatin code:
public class RankTableWidget extends Composite {
public class RankProvider implements DynaTableDataProvider {
private final RankTableServiceAsync rankService;
private int lastMaxRows = -1;
private Person[] lastPeople;
private int lastStartRow = -1;
public RankProvider() {
rankService = (RankTableServiceAsync) GWT.create
(RankTableService.class);
ServiceDefTarget target = (ServiceDefTarget) rankService;
String moduleRelativeURL = GWT.getModuleBaseURL() + "ranktable";
target.setServiceEntryPoint(moduleRelativeURL);
}
public void updateRowData(final int startRow, final int maxRows,
final RowDataAcceptor acceptor) {
if (startRow == lastStartRow) {
if (maxRows == lastMaxRows) {
pushResults(acceptor, startRow, lastPeople);
return;
}
}
rankService.getPeople(startRow, maxRows, new AsyncCallback(){
public void onFailure(Throwable caught) {
acceptor.failed(caught);
}
public void onSuccess(Person[] result) {
lastStartRow = startRow;
lastMaxRows = maxRows;
lastPeople = result;
pushResults(acceptor, startRow, result);
}
});
}
private void pushResults(RowDataAcceptor acceptor, int startRow,
Person[] people) {
String[][] rows = new String[people.length][];
for (int i = 0, n = rows.length; i < n; i++) {
Person person = people[i];
rows[i] = new String[3];
rows[i][0] = person.getPosition();
rows[i][1] = person.getLogin();
rows[i][2] = person.getMoney();
}
acceptor.accept(startRow, rows);
}
}
private final RankProvider rankProvider = new RankProvider();
private final DynaTableWidget dynaTable;
public RankTableWidget(int visibleRows) {
String[] columns = new String[] {"Position", "Nick", "Sum"};
String[] styles = new String[] {"pos", "nick", "sum"};
dynaTable = new DynaTableWidget(rankProvider, columns, styles,
visibleRows);
initWidget(dynaTable);
}
@Override
protected void onLoad() {
dynaTable.refresh();
}
}
Please tell me, how should I modify the code to make the table update?
I think it's the matter of modifying the getPeople() function so I
don't need to paste the rest of the code (correct me if I'm wrong)

GWT-Ext was a *wrapper* around the pure-JS Ext-JS lib, just like SmartGWT is a wrapper around SmartClient (AFAICT); this means that your page will load the whole set of widgets, classes, methods, etc. even those that won't ever be used. Ext-GWT (or GXT) on the other hand is a *port* of Ext-JS over to GWT, which means that only the code you actually use will end in the javascript loaded by the browser. That being said, I haven't ever used any of those libs, so I can't really tell which one to choose... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

So I have a modification to SearchProductsPresenter.onBind()
I want an instantiation that I can mock in this part of the code. There
are several steps to accomplish this:
o An /Action/ abstract class. This class supports real and mock requests.
o The /Requester/ interface
o One or more /Requester/ implementations (e.g. Flavors, Products). Each
implementation can be real or mock. The RequestBuilder.Method will be
set in the real implementation as well any request and authentication data.
The mock implementation declares a private /Response/ class. It is in
this class that the mock data are generated.
o A /Service/ interface
o A real /Service/ implementation
o A mock /Service/ implementation
There are two gin modules. One contains
bind(Requester.class).to(MockFlavorRequester.class);
bind(Service.class).to(MockServiceAsync.class);
and the other contains
bind(Requester.class).to(FlavorRequester.class);
bind(Service.class).to(ServiceAsync.class);
This is in support of a /Presenter/ class that does not know if it's
processing real or mock data.
private final Server server;
private final Service service;
private final Requester flavorRequester;
@Inject
public ServerAddPresenter(Display display,
// This service can be either real or mock
// ... do an XHR or mock the Response
Service service,
EventBus eventBus,
// This requester can be real or mock
// It can process real data or generate mock data
Requester flavorRequester,
Server server) {}
Please see http://pastie.org/599877
I look forward to your comments.

Re: Based on access privileges enable/ disable buttons at the time of application startup
Sri already gave you good suggestions. Note that you can avoid the RPC calls if you include the permission data inside your HTML host page. I did this in a previous application by adding a javascript variable inside the host page, and accessing it through the dictionary class. More information here: http://google-web-toolkit.googlecode.com/svn/javadoc/1.6/com/google/gwt/i18n/client/Dictionary.html Another solution, if the permission data is complex, would be to serialize this data, put it in your host page, and use it like a RPC payload. This is described here: http://www.techhui.com/profiles/blogs/simpler-and-speedier-gwt-with I discussed it in more details in this thread: http://groups.google.com/group/google-web-toolkit/browse_thread/thread/c932eec126195a8f Regards, -Etienne --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: "semaphores" in gwt
Woops... Missclicked :/ Let's try again: -- Thomas and Christian already gave you useful answers. I want to add the following: - As of now, Javascript is single threaded , so you don't have concurrency problems. So you know the onSuccess() method of your RPC services can not be run concurrently, and you may then use boolean flags to know whether you already got the other RPC response. There are some talks of making JavaScript multi-threaded with worker threads ( https://developer.mozilla.org/En/Using_web_workers ), but you don't have to worry about that now. - If you are interested in reducing your app's startup time, you could avoid the 2 additionnal http requests from the RPC calls by "pre- loading" the RPC data in your HTML host page, as explained here: http://www.techhui.com/profiles/blogs/simpler-and-speedier-gwt-with This technique needs some setup, but it seems like it would be perfect for your use case. - If your RPC calls fetch some really simple data like the current user's nickname/firstname/lastname, you could simply embed this data inside a javascript variable in your host page, and access it by using a GWT dictionary.

GWT plugin: Problem when project name is changed
Hi I have a GWT project named X created by Google plugin. Then later I want to change the name to Y, so I right clicked Project X -> Refactor -> Rename ... -> New name: Y When run, it will complaint the working directory does not exist: /X/war It seems that launch configuration is still referring to the old name. Would it be possible for the plugin to rename the launch configuration, hosted page and etc? -- Hez --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Based on access privileges enable/ disable buttons at the time of application startup
a) After authenticating the user, make a RPC call to the server to get the permissions map for the user. On the server side, get the userid from the session rather than the request parameter. b) On the client side, use the permissions map to figure out if a particular link can be shown or not. c) Be aware that client side disabling/enabling buttons is only usability and not security. In each your RPC Services you must check if the logged in user has the necessary permissions to perform the operation. Again, it is a matter of using the session object to see if the user is authorized. -sri On Aug 30, 4:08 am, mathesmond wrote: > Hi, > > I would like to enable/disable buttons in my application based on user > permissioning , this should happen at the time of application startup. > can you please provide me some pointers as to how this can be > achievedi > > Cheers --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Making a fancy GWT Chart
There are multiple ways to achieve this -
If you want to continue generating images in java, you will also have
to write a Servlet which returns the BufferedImage in one of the
formats (gif/jpeg etc). Then, in your ImageWidget you would give the
URL for your servlet. In the servlet, you would do something like this
-
a) Read the request parameters and created a BufferedImage
b) Set the appropriate content-type request headers to the tell the
browser that you are sending an image ('image/jpg' or 'image/gif'
etc)
c) Use the ImageIO class to copy the BufferedImage to the servlets
output stream
You can also take a look at FusionCharts. It provides a flash based
client side graph/chart library. In this case, you would have to
create an XML in your client side code and then pass it to
FusionCharts using its Javascript API.

Re: Has anyone used gwt-validation api? or is there a better one?
Its a good framework as long as you only want to do client side validations. The moment you want to do server side validations, GWTC starts complaining. The Annotation based framework would start requiring server side classes, which won't be available to GWTC.

Re: How to use multiple servers in a single client
Simply put, it can't be done. Cross Domain restrictions require that javascript code only communicate with the server from which it originated. So, all RPC requests that you make must go to the same server. However, you can have a simple facade on your server. You can let your webserver simply proxy requests to a different server where you can take appropriate action. Something like /update proxies to servera.com and /delete proxies to serverb.com. To the browser, it is always the same web-server, so no cross-domain issues. On Aug 28, 9:11 am, Ganesh wrote: > Hi > > I am working on a GWT application.

Re: Did you forget to inherit a required module? about jdo
Not all classes, of course. GWT related classes must be in client package
(or subpackages or packages that you include in your gwt.xml file as ).
It's difficult from here without source code to help you. Otherwise, did you
inherit User module in your gwt.xml file, and specify an entry-point class
as well?
For example, using your data:
in package com.Demo3 you should have a file named Demo3.gwt.xml as follows
(basic configuration):
http://google-web-toolkit.googlecode.com/svn/tags/1.7.0/distro-source/core/src/gwt-module.dtd";>
and in package com.Demo3.client:
public class YourEntryPoint implements EntryPoint {
public void onModuleLoad() {
/* everything starts from here */
}
}

Re: Did you forget to inherit a required module? about jdo
You should move your classes out of the package 'client'. This is because
GWT consider it by default as a source package, so the compiler will search
for source code to translate Java into Javascript.

Help With OnBrowserEvent
I'm trying to implement both right click and drag and drop. I want a
draggable label to also be rightclickable. However, when I add an
"onBrowserEvent" method to my label (to add right click functionality)
it removes the ability to drag objects (even if this function is
empty). It seems like this is because a left click seems to call
onBrowserEvent repeatedly. The drag functionality works when I remove
this function completely, but of course it removes the right click
functionality. Is there any way to disable calling onBrowserEvent on a
left click?
small bit of my code:
public class AdvLabel2 extends Label implements AdvClickNotifier {
private AdvClickListener listener = null;
public void onBrowserEvent(Event event) {
GWT.log("onBrowserEvent", null);
event.cancelBubble(true);//This will stop the event from being
propagated to parent elements.
event.preventDefault();
switch (DOM.eventGetType(event)) {
case Event.ONMOUSEUP:
if (DOM.eventGetButton(event) == Event.BUTTON_LEFT) {
GWT.log("Event.BUTTON_LEFT", null);
listener.onClick(this, event);
}
if (DOM.eventGetButton(event) == Event.BUTTON_RIGHT) {
GWT.log("Event.BUTTON_RIGHT", null);
listener.onRightClick2(this, event);
}
break;
case Event.ONDBLCLICK:
break;
case Event.ONCONTEXTMENU:
GWT.log("Event.ONCONTEXTMENU", null);
break;
default:
// Do nothing
}//end switch
}
}

I used that for enabling right clicks.
