Re: novice question
Hi Shaul, Generally, GWT has only one html page. Everything is done by showing and hiding stuff. For example, you have a menu panel on the left and a display area on the right. When you click a menu item, your program swaps out the current display and swaps in the new one. The actual html file is the same one and is not reloaded, but you hide the 'home page' widget and show the 'about us' widget. If by 'two modules' you mean two entrypoint classes, then all the entrypoint classes get run when you start the application. If you mean something else, then yuo'll have to explain a bit more about what you have done.

Re: Does panel has border?
To add the borders to a panel, we will create a style in CSS:
.test {
background-color: red;
border: thin solid #00;
margin: 10px;
}
Then set the style to a panel like this:
FlowPanel panel = new FlowPanel();
panel.setWidth("100%");
panel.setHeight("100%");
// panel.addStyleDependentName("test") does not work?
panel.setStyleName("test");
Why the above code works with setStyleName() but nothing happen when calling
addStyleDependentName()?

Re: RPC + Serializable objects

Re: SetAccesskey question...
thank for your answer..
But I don't understand your answer. May be my question is strange...
( english problem.. )
I know keyboard event. ( keyPress, keyDown etc )
I want know is that setAccessKey()...
setAccessKey event is static.. ( => mouse focus not need )
btn.addKeyEvent( ~~ ) is local.. ( => mouse focus need )
example))
short cut : Ctrl + F
I want CTRL + F => alt + f + c
thank... I need your help.

Re: PureMVC
Hi Thomas,
I've seen some widgets be injected other widgets but not a single
event listener (or I missed something).
It's true that for my project I only injected some widgets on a main
panel. That's the project specific choice. Because it's more easy to
do that.
I'am not very clear your use case now. Let me have a guess for the use
case:
1. We have two widgets w1 and w2, both of them would fire Event
clickEvent.
2. We need one Event Listener named CommonEventListener, we expect it
can be used to process clickEvent fired from both w1 and w2.
3. We hope the container, that is Gin to inject when system
initialize. So refractor the code like.
W1 w1 = new W1();
w1.addClickEventListener(new CommonEventListener(p1,p2){});
W2 w2 = new W2();
w2.addClickEventListener(new CommonEventListener(p1,p2){});
by:
CommonEventListener aCommonEventListener =
injector.getCommonEventListener();
W1 w1 = injector.getW1();
w1.addClickEventListener(aCommonEventListener);
W2 w2 = injector.getW2();
w2.addClickEventListener(aCommonEventListener);
Because polymorphism is not usable in GWT, we can not use W1 or W2's
common interface or base class as CommonEventListener. My suggestion
is:
private W1 w1;
private W2 w2;
@inject
public CommonEventListener(W1 w1,W2 w2){
//w1 and w2 should be created by ginmodule as singleton instance.
this.w1 = w1;
this.w2 = w2;
}
public void onClick(Event e){
if(e.getSource() == w1){
//w1.update();
}else if(e.getSource() == w2){
//w2.update();
}
}
I don't think it's an perfect solution(you must change the parameter,
as you said, use List is same like ). But it should be able to
manage the listener and ui creation by container and unit test could
be implemented easily.
Hope that is not confusing.

Re: Deploy RPC on WAMP5 Server
GWT-RPC uses Java Servlets on the server side. apache + mod_php doesn't directly support servlets, so you'd have to install a servlet container as well (tomcat or jetty for instance). however, the better option, if the rest of your application is written in PHP would be to just forgo GWT-RPC and instead use RequestBuilder and JSON to communicate with your server. -jason On Oct 26, 2008, at 7:29 AM, Muhannad wrote: > > Hi, > > I'm building a website using PHP, MYSQL, and Apache (WAMP5 server).

GWT with the G1
Has anyone ran into any issues with the browser on the G1? Our site is pretty much all GWT and the G1 browser seems to not be able to make RPC calls. I'm still trying to figure out what is going on, but there is something bizarre going on. Like I said the browser on the G1 is behaving like the RPC servlets are not configured correctly. However I'm not getting any logging coming through on the server side. If anyone has any thoughts let me know, I just tested out the GWT Kitchen Sink and all of the client side seems to work, as on my site. It's just the RPC calls that are failing. -Aaron O'Brien Shawnee Kansas --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Use the same code within a JSNI method.
Eventually you could instanciate a JSONObject to wrap your overlay,
but it has a cost.

Sorry, I should have been clearer: I know what Guice (and Gin) and
Spring are. Just that they cannot AFAIK inject listeners (i.e. call
some addXListener method, eventually several times on a single
instance). Of course you can use method injection with a
setXListeners(List) method (should be supported by Gin as
of today) but I wouldn't call it "injecting event listeners"; or
inject event sources or event targets but that's not flexible at all
(why having "event listeners" in this case, just keep references to
the injected widgets and call the appropriate methods on them)

I've seen some widgets be injected other widgets but not a single
event listener (or I missed something).

Re: PureMVC
Hi,
Actually, Gin is used to implements Ioc Container. It can bind everything
not only event Listener.
Guice or Spring can do that naturally, but because GWT can not support
Java reflection, such as forClass("className").getInstance. So Gin use
generic and annotation to do that.
I have a open source project to do that. GinModule and GindInjector are
key players for that.
please check out here, that's a real world project.

Re: Suggestion: GWT port to Desktop
We have a similar requirement, to have part of our GWT app also run standalone on someone's desktop. We haven't done anything yet, except for designing our app using MVC. We have an GWT view and a batch testing view and will add other views later.

Re: RPC + Serializable objects
Hey Ravi, Thanks for the detailed input. I should have updated this for everyone's benefit and I'll try to get into that habit. Much like you mentioned, I found that XmlBeans would not be a viable approach with the GWT/RPC mechanism. Although, without thinking deeper about the datatypes, I attributed it to the fact that the source that's generated extends from XmlObject and others, which I'm sure are contained in jars of their own and ultimately identifying and downloading the source for each of these items would probably be a really bad idea :). Thus, I'm doing exactly what you're doing at the moment i.e creating Transfer Objects to contain the bean data. As for the Serializable issue, you could be right but isn't it also that GWT is trying to deprecate isSerializable so, ideally they do want to be able to support as much of the Standard java serializable classes if not all? So, not sure if we should or should not be using the interface. I guess that's a personal decision though. Since you're doing somewhat similar stuff, a question for you now. Have you had any experience in trying to integrate GWT into any framework? I ask because I currently have a Struts framework for the application that's being enhanced by adding this GWT module. And "ideally" I'd like not to move too far from the Struts framework so any incoming requests should be rerouted from the custom RemoteServiceServlet to be then defined at the struts-config so that the Action-Delegate-DAO structural integrity is maintained. i.e Browser <---> GWT (Client) <---> GWT (Server - RPC) <> SomeAction Thanks for any info.

Re: How do you actually use MVC?
Thanks for your very elaborate answer! I spend some time googling around to see what other peoble do. I think a nice way of separating the three entities is implementing the Observer/Observable interfaces. Possibly the PropertyChangeSupport interfaces. However, these are not directly available in GWT (yet) and the later requires GWTx. Are many of you, out there, using PropertyChangeSupport or similar on- change events? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Tor: Awesome.
Just downloaded the beta python for netbeans. -awesome-. One thing that is seriously borked in this install, though: whitespace. Backspacing to go back to previous levels is all screwed up and tends to jump in steps of 4, right in the middle of indents. So, if for example I have a method indented 2 spaces, and inside it, a for loop, with the body of the for loop indented 6, and I hit backspace, it'll first go back to 4 spaces in, which is not an indent at all, and another backspace will then go to 0, which isn't where I wanted to be either.

Does panel has border?
Hi How can I draw a border, and set the background color of a FlowPanel?

Re: applicationCreator to generate Ant tasks
The projectCreator does generate an Ant build file. I actually submitted a patch a while back that adds a little more zing to that build file. It's been marked low priority, but you can add your star to the issue if you want to see it included. Here's the issue: http://code.google.com/p/google-web-toolkit/issues/detail?id=2315 For compiling to JS you can also try out the GwtCompilerTask, which is available in the GWT Incubator project. I wrote about the custom Ant task here: http://publicint.blogspot.com/2008/10/introducing-gwtcompilertask.html I've thought about a GwtHostedModeTask, but personally I prefer starting hosted mode using Eclipse since it handles the debug hooks for me.

Re: Deploy RPC on WAMP5 Server
I don't think the out of the box WAMP will serve servlets...JSP pages. You could use it out of the box if you did JSON with PHP to be your client/server bridge. But if you want to do GWT-RPC, you need a servlet container and Tomcat does that nicely. Also check out Jetty, it's very slick and fast as well and both should be able to fit into the WAMP stack with no problems.

applicationCreator to generate Ant tasks
Hi The applicationCreator generates scripts to allow us to start application in hosted mode, translates the Java to JavaScript (creating web folder under www) and etc. I think it is also useful to add -ant option to applicationCreator, so that applicationCreator will auto-generate Ant tasks to start application in hosted mode, and to translate the Java to JavaScript in www folder and etc. This is useful for example, create a Ant tasks to clean the directories, then compile the Java classes, followed by the translation to JavaScript and finally, create the WAR file and etc. What do you think? -- Hez --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Enumerating Javascript Overlay Types
Hi,
In Javascript its possible to enumerate Javascript Objects:
e.g:
var my obj = {"key1": "value 1","key2":"value 2", "key3","value3"};
for (var key in obj)
{
var currentValue = obj[key];
};
I would like to know how to do this with Javascript Overlay Types in
GWT.
Thanks in advance!
Thanks,
Mathew

Deploy RPC on WAMP5 Server
Hi, I'm building a website using PHP, MYSQL, and Apache (WAMP5 server). In addition, I used GWT to create some widgets that access the server through RPC. Would you please help me how to deploy my GWT-RPC on the WAMP5 server? Do I need to use Apache Tomcat instead of WAMP5?

Re: Drag&Drop + database
I solved! The problem was in the toString of widgets' text.
widget.toString returns a result like this:
1) ciao ciao
([EMAIL PROTECTED])
So, it is clear that to capture the right data to be included in db is
necessary to consider the sottoscringhe created by parentheses ")",
"(" ")" , and not by spaces

Drag&Drop + database
Hello World! for my GWT project I am using the library gwt-dnd for the
functionality of drag & drop. I have two lists box, in the left a list
of widget with data collected from the database. From db, I exstact
the object Person, that contains attributes:id, nome, cognome,email,
and I add these to the list:
public void onSuccess(List result) {
Iterator iter = result.iterator();
int i = 1;
while(iter.hasNext()){
i++;
Person item = iter.next();
dualListBox.addLeft(item.getId() + ") " +
item.getNome() +" " +
item.getCognome() +" (" + item.getEmail() + ")" ) ;
}
In the right list, I can drag the widget from the left. On this list I
do a query to save the data in database.
I want to add each Person in a Team, adding the "id" of the person and
the "id" of the Team in a table Person-Team. The id_Team is written
correctly in the table Person-Team, but the data of Person are not
captured well, then not properly sort of conversion from a widget
object.
I do like this:
Person person = new Person();
ArrayList widgetRight = dualListBox.getWidgetRight();
Iterator iterWidget = widgetRight.iterator();
int indexSpace1, indexSpace2, indexParentesi1,indexParentesi2;
String dati;
while(iterWidget.hasNext()){
Widget item = iterWidget.next();
dati = item.toString();
indexSpace1 = dati.indexOf( " " );
indexSpace2 = dati.indexOf(" ", indexSpace1+1);
person.setNome(dati.substring(indexSpace1+1, indexSpace2 ));
indexParentesi1 = dati.indexOf("(", indexSpace2+1);
person.setCognome(dati.substring(indexSpace2, indexParentesi1-1));
indexParentesi2 = dati.indexOf(")", indexParentesi1+1);
person.setEmail(dati.substring(indexParentesi1+1, indexParentesi2));
comunicationService.getIdPerson(person.getNome(),
person.getCognome(), person.getEmail(), callback9);
}
final AsyncCallback callback9 = new AsyncCallback(){
public void onFailure(Throwable caught) {
// TODO Auto-generated method stub
}
public void onSuccess(Object result) {
long idNew =
Long.valueOf(result.toString()).longValue();
lab = new Label("nome = " +person.getNome() + " Cognome
= "+
person.getCognome()+" Email = "+ programmerTO.getEmail() + " id =" +
idNew);
panelFormContent.add(lab);
idList = new ArrayList();
idList.add(idNew);
Iterator iterId = idList.iterator();
while(iterId.hasNext()){
long itemId = iterId.next();
comunicationService.createPersonTeam(itemId,
idTeamRet,
callback10);
}
}};
Writing in the Label name, id, surname and email is this:
nome = id="ext-gen163" Cognome = class="gwt-HTML dragdrop-draggable
dragdrop-handle">3) enrico spanu Email = [EMAIL PROTECTED] id =0
So, only the email is properly captured by the string. How can I do
this kind of conversion so that it works?
Thanks!!

JUnit Testing error
I use GWT with Hibernate. For testing my server side Methods I use the GWT-JUnit implementation. It works fine. But now I've added a new Testcase. It first loads the data that is to be expected as the answer by the server from the database (via Hibernate) and subsequently compares the loaded data with the data retrieved from the Server. Actually it is simply an assertEquals which I want to perfrom.
