Have you tried using CSS?

.my-tab-content {
 position: absolute;
 top: 0;
 left: 0;
 bottom: 0;
 right: 0;
}

this *should* work as long as it's parent is positioned (relative/
absolute)...

The new layout panels I think require a RootLayoutPanel not a
RootPanel... but I can't remember exactly.

Cheers,
Dave

 Hi,

 sorry for repeating and posting in this thread without solution, but I
 must say that TabLayoutPanel is useless for me if its size cannot be
 maximized.

 So I'll have to build my own TabPanel, but this is not satisfactory
 since a framework should prevent me from building my own versions of
 things that should be already available.

 I cannot understand why TabLayoutPanel insists on having its content
 area squeezed at the top...

  Thanks! I tried with dummy panels, VerticalPanel and SimplePanel. I
  tried absolute and relative sizes but nothing seems to have an effect.

   private void init ()
   {
    TabPanel pnl = new TabPanel ();
    pnl.setSize (100%,100%);
    //pnl.setHeight (100px);

    SimplePanel p = new SimplePanel ();
    p.setPixelSize (100,200);
    HTML txt1 = new HTML(This isa Text 1.);

   I think for that you will require to set its border explicitly.
   that will settle this issue.
   you can add a dummy panel on tab home1 or home2 and set its height
   but here  if you set height using % then it will not work you will have to
   set height in pixels or any other like em...

   i hope this will work.

In addition, it would set the wrong height! The height of the TabPanel
(pnl) is ok, it covers 100 % of the available space.
But the VerticalPanel p that I add as the client panel to one of the
tab pages is not affected.

Look at this screenshot:
   http://yfrog.com/4rtabpanelp

The TabPanel (red border) is ok. But its child panel (blue border) is
crunched at the top.

How can I get the blue border maximized to the red border?

Re: Different paging behaviour for CellTable and SimplePager

2010-07-12 Thread DennisLaumen

Hi,

Overriding seems like a hard thing to do as CellTable depends on a
private final attribute of type CellListImplT for most of its logic.
It seems like the easiest way to implement the paging behavior
described in the above post would be to copy CellTable and change the
code here and there. Unfortunately, this wouldn't be a very elegant
solution, let alone maintainable as it appears these widgets are still
moving targets.

Can anyone offer me any tips? Maybe some Googlers with sage advice?

Regards,

Dennis Laumen

Re: GWT RPC with Adobe AIR 2

Well i think i ve figured it out

the first Problem is  in the RequestBuilder class. (Well actually is the
XMLHttpRequest Class)

take a look at the  XMLHttpRequest Class in the method *clearOnReadyStateChange
(*line 113)

 public final native void clearOnReadyStateChange() /*-{
var self = this;
$wnd.setTimeout(function() {
  // Using a function literal here leaks memory on ie6
  // Using the same function object kills HtmlUnit
 * self.onreadystatechange = new Function();*
}, 0);
  }-*/;

this throws an error inside adobe AIR.

So to overcome this i did someting like this inside the RequestBuilder Class
in the doSend Method (around * line 381*)


  // Must set the onreadystatechange handler before calling send().
xmlHttpRequest.setOnReadyStateChange(new ReadyStateChangeHandler() {
  public void onReadyStateChange(XMLHttpRequest xhr) {
if (xhr.getReadyState() == XMLHttpRequest.DONE) {

/**
 * Avoide new Function security error in Adobe AIR
 */
   * if(! Runtime.isAIRRuntime()){*
*** *
*** **xhr.clearOnReadyStateChange();*
*}*
* *
*  request.fireOnResponseReceived(callback);*
*}*
  }
});


The Runtime class is a class i created my self.


After you have done this you are half way :)

You need to make a change in RemoteServiceServlet class too. Because  the
modeBaseURL of the adobe air application istarts with
*app:/ . This will throw an Exeption so you need to change that *
*
*
*i did something like (RemoteServiceServlet around line 41*) * :*
*
*
*
*
*
if (moduleBaseURL != null) {
  try {


  if(moduleBaseURL.indexOf(app:) = 0){

 moduleBaseURL =  moduleBaseURL.replaceFirst(app:/, 
http://127.0.0.1:/;);

}


modulePath = new URL(moduleBaseURL).getPath();
  } catch (MalformedURLException ex) {
// log the information, we will default
servlet.log(Malformed moduleBaseURL:  + moduleBaseURL, ex);
  }
}



And after that GWT RPC is running with Adobe AIR.

Hope this could help

 Yeah you are right.
 It looks the gwt is generating some new Function(){...} constructs,

 what adobe air doesnt like.

 Anybody has a solution to this ?
 I m also really  interested

  Why dont just use the RequestBuilder  and send  the response back as
 JSON or
  XML ?

 Because you have to write some of the conversion process manually
 which is automated with GWT.

 Unless you know of a project that is a drop-in replacement for RPC
 with no extra code required?

Surely a nasty bug! in RPCServletUtils.readContentAsUtf8

2010-07-12 Thread Shawn Brown

Hi,
 Can anyone suggest a work around for
http://code.google.com/p/google-web-toolkit/issues/detail?id=5109

I'll have to look at the src when I get time but this is nuts to me.

Does this work for you?

private String showRequestedMethod(ServletRequest request) throws
IOException, ServletException {

//requestCopy2=(HttpServletRequest) request;

//HttpServletRequest requestCopy =(HttpServletRequest) request;

String r1 = request.toString();
Log.info(request.length + request.getContentLength());
String payload =
RPCServletUtils.readContentAsUtf8(((HttpServletRequest) request));
Log.info(payload: +payload);
pay=payload;
RPCRequest rpc_request = RPC.decodeRequest(payload);
//  Log.info(rpc. method  + rpc_request.getMethod());
Log.info(r.ts +request.toString());


Log.info(request.length + request.getContentLength());
String r2= request.toString();
String payload2;
try {
payload2 = 
RPCServletUtils.readContentAsUtf8(((HttpServletRequest) request));
Log.info(payload2: +payload2);

} catch (Exception e) {
Log.info(Why the #$% + e.getMessage());
e.printStackTrace();
}
Log.info(r.ts2 +request.toString());

Log.info(Are r1 and r2 the same +r1.equals(r2));

return rpc_request.getMethod().toString();
}

I get an error every time saying Client did not send 197 bytes as
expected.  Why it's the same request that is passed into
RPCServletUtils.readContentAsUtf8(((HttpServletRequest) request));

Basically I am checking for authorization in a filter so I need to
find out what rpc method is being called.  Then if the user has auth,
I let it go through but then see an error when the method is really
called.  I call it twice in this method as an example to narrow down
what is failing.

Any help?  Please!

Shawn

GWT and Spring - More Generation Options

2010-07-12 Thread Christiana Thompson

This week Genuitec and Skyway Software released the second milestone
(M2) of MyEclipse for Spring 8.6, which includes scaffolding for GWT
applications.  With this new release, our users can now generate full
ready-to-run GWT applications from a domain model (i.e. DB tables,
Java Beans, or JPA Entities).

As excited as we are about this new feature, we are eager to get
feedback from the GWT community.  Some key aspects of our GWT
scaffolding:

- The functionality is based on GWT 2.0.4 (no dependency on early
access or non-GA libraries)
- The generated code is based on current best practices (from last
year's Google I/O session with Ray Ryan and the MVP tutorials from
Chris Ramsdale) and UI Binder
- The GWT RPC services are based on Spring Services, and include
conversion of JPA objects to/from data transfer objects (DTO) that are
optimized for GWT
- The generated applications support both Spring 2.5.x and Spring 3.0

Again, we'd appreciate input and feedback from the GWT community.
Additional information and resources are as follows:

Passing data between modules - MVP architecture

2010-07-12 Thread grandanat

Hello all.
I Have a simple scenario:
-a GWT application with an application controller that handles history
and initialize modules. ( a module is an entity formed by a presenter
+ view - classic MVP, nothing special)
-from a module should be opened another module and pass init data to
it, and then after child module finishes its job to return another
response data.

I followed two approaches and i would like to comment them.

1.eventBuss approach - pass data within events.
i have StartChildModuleEvent event that encapsulates a module parent
ID, and some init data, and an ExitChildModuleEvent event that
encapsulates some return data.


2 callback approach.
i added to my modules a callBack handler


public abstract class ModuleCallBackHandlerD, T implements
DataCallBackHandlerT {

  private ModuleID parentID;

  private D initData;
  private T returnData;

  public ModuleCallBackHandler(ModuleID parentID) {
this.parentID = parentID;
  }

  public ModuleCallBackHandler(ModuleID parentID, D initData) {
this.parentID = parentID;
this.initData = initData;
  }

  public void onCancel(){
  }

  public void onFailure(Throwable caught){
Window.alert(AppGin.injector.getAppConstants().msg_moduleError() +
 :  + caught.getMessage());
//caught.printStackTrace();
  }

  public ModuleID getParentID() {
return parentID;
  }

  public D getInitData() {
return initData;
  }

  public T getReturnData() {
return returnData;
  }

}


and when i want to init a child module i instantiate a new callback

AppGin.injector.getAppController().doStartChildModule(ModuleID.ITEMSEARCH,
new ModuleCallBackHandlerString, Item(getModuleID(),
itemID) {

  @Override
  public void onSuccess(Item result) {
//do some stuff - update this module with received
data
  }

});

I would like some opinions regarding this two approaches.

Thanks all

New to GWT, Questions on loading modules...

2010-07-12 Thread boringNerd

Hi, I'm extremely new to GWT and was playing around with it the past
few days and was beginning to see the wonders of it. Just today, I was
learning how to load additional modules and there's a question that's
been bothering me

Can someone please explain to me the purpose of creating a .gwt.xml
file in your module package (eg. com.mytestapp.security)? If I want to
access additional modules I wrote, I can just define it in the source
tag under the main .gwt.xml right? I'm not particularly familiar with
this 'cause I'd been working mostly with PHP all the while.

Using large files in gwt

2010-07-12 Thread Roope

Hi

I'm currently developing some bioinformatics tools and I want to make
them as web apps.

The thing is that user needs to input files that might be up to 4Gb
but usually the biggest is just about 250Mb.

There are two main use-cases:
1. Steaming the file and taking just some small parts of it to string
2. Reading the whole file and making object from each line in file

I would like to do all the file processing in client side, but I
understood that it is not yet possible using gwt?

If I keep the server local it is feasible to upload some 250mb files
and process them at the server side, but I have no success so far in
this, even with 10mb file.

So what would you suggest me to do? Besides dumping the web
application idea and making some java applet.

Roope

Firing native event in gwt 2.0.3

Hi all,

I have a small problem, moved from gwt 1.6 to gwt 2.0.3,
and i have this problem to fire manually native event!!

In 1.6 that was possible with Document.fire*event() methods,
but I cant find a way how to do this in 2.0.3 ?!

One more problem i have:
I use google map api, and I cant find a way how to change
the default hand cursor over the map!!!

I used this code of line:

map.map.getPane(MapPaneType.OVERLAY_LAYER_PANE).getElement().addClassName(my-
map-cursor);

and only with this PaneType: OVERLAY_LAYER_PANE
I get the new style cursor, but when mouse is moved over the map
the cursor random changes between the default hand cursor style,
and my cursor style!!!

Tnx for the help!

Client OR mapping

How do you maintain rich OR mapping in client.

For example CUSTOMER has many ORDERS and each ORDER has many ITEMS.

Now GWT makes DIFFERENT ajax calls wherein CUSTOMER, ORDER, ITEM are
loaded at separate times (eager fetching does not look good thus lazy
fetching only).

Thus do you manually map objects again in client ( or do you store
CUSTOMER, ORDER, ITEM  in separate shared variables or something
else.).

I am sure you experts out there must have some directions for us.

GWT adoption

Do you guys think that GWT will the most widely used framework in
future ( or there will be mix of other frameworks in future. If yes
than which frameworks).

I am little worried that why GWT is not adopted at a rate I would have

Client session

How to implement a client side session ( and any best practices to
implement them).
Is it to just create a static variable ?

How do two different MVP widgets share MODEL data (i.e. user input
data).

How do two different MVP widgets share VIEW data ( for example if
display of one widget is dependent on mouse click location of second
widget, than how do two widgets share view information i.e. mouse
click location).

Again, all widgets are designed using MVP and send events using
EventBus.

How can I formulate the given problem in GWT context

2010-07-12 Thread Raza

I have just started using GWT for web interface for our application.

My app has three different views for three different types of users.
Each user has different type of interface (i.e. different navigation
different menus etc).

There is one login page which will be index page of the application.
The user shall enter the credentials and will be redirected to his/her
section.

My problem is that how I can transform this scenario in GWT context.
Weather I shall have four modules (i.e. one for login and other three
for three type of users); weather there will be one module and I just
have to change/load panels according to the user view type.

Kindly help me in this regard.

Cheers

Raza

gwt-visualization Table vs gwt-incubator ScrollTable

Hi,
I have seen examples of both and like both of them, at least for the basic
purpose of displaying data in Table form and with paging. However, I am
unable to pick one over the other for the following reasons:

a) Both lack Column Reordering using Drag and Drop that I wish in my Table
View.
I realize that one can use gwtQuery or gwt-DND to achieve the same, but I am
not sure with which one it would be easier.

b) I would want to replace default column headers with some clickable
buttons - to achieve : i) hide a given column ii) show small popup picking a
filter on the column.
Not sure with which one of the two, its feasible (or easier) to achieve.

c) I am not sure whether gwt-incubator stuff will ever ( or when) will it
get into main gwt-library

d) It seems that gwt-visualization is JSNI wrapper over original google
visualization JS library. Is it going to be a big factor in terms of
performance?

e) Any guidelines on why  when  should one pick one over the other!

Thanks,
Akshay

Passing data between modules - MVP architecture

2010-07-12 Thread grandanat

Hello all.
I Have a simple scenario:
-a GWT application with an application controller that handles history
and initialize modules. ( a module is an entity formed by a presenter
+ view - classic MVP, nothing special)
-from a module should be opened another module and pass init data to
it, and then after child module finishes its job to return another
response data.

I followed two approaches and i would like to comment them.

1.eventBuss approach - pass data within events.
i have StartChildModuleEvent event that encapsulates a module parent
ID, and some init data, and an ExitChildModuleEvent event that
encapsulates some return data.


2 callback approach.
i added to my modules a callBack handler


public abstract class ModuleCallBackHandlerD, T implements
DataCallBackHandlerT {

 private ModuleID parentID;

 private D initData;
 private T returnData;

 public ModuleCallBackHandler(ModuleID parentID) {
   this.parentID = parentID;
 }

 public ModuleCallBackHandler(ModuleID parentID, D initData) {
   this.parentID = parentID;
   this.initData = initData;
 }

 public void onCancel(){
 }

 public void onFailure(Throwable caught){
   Window.alert(AppGin.injector.getAppConstants().msg_moduleError() +
 :  + caught.getMessage());
//caught.printStackTrace();
 }

 public ModuleID getParentID() {
   return parentID;
 }

 public D getInitData() {
   return initData;
 }

 public T getReturnData() {
   return returnData;
 }

}


and when i want to init a child module i instantiate a new callback

AppGin.injector.getAppController().doStartChildModule(ModuleID.ITEMSEARCH,
   new ModuleCallBackHandlerString, Item(getModuleID(),
itemID) {

 @Override
 public void onSuccess(Item result) {
   //do some stuff - update this module with received
data
 }

   });

I would like some opinions regarding this two approaches.

Thanks all

Dependency injection perf issues

I used DI i.e. used @Inject to inject (Presenter, EventBus) in all of
Views.

Now it seems that if I use DI than all views are generated at web app
intial start time in browser. Thus start time becomes slow. Am I
right? ( I think I heard something like this before also but just want
to validate).

So if above is true than using @Inject is no good .. right? ( or where
can we use @Inject ).

Can we use use @Inject to lazily create views instead of web app start
time?

The Contacts1 MVP tutorial worked well (http://code.google.com/intl/nl-

continue with contacts MVP part 2 but I have found this part very
confusing.

Has someone got a working Eclipse version which can be imported? The
one offered on the site isn't complete. I tried to update part 1 using
the part 2 tutorial but this gives me all sorts of errors I'm unable
to resolve. (learning from a working example is essential)

Re: Dependency injection perf issues

2010-07-12 Thread david.herv...@gmail.com

Hi,

the fact that you are using DI does not change your startup time. Your
application will take approximately the same time to load if you does
the injection by hand.
Actually, I think you want to create your view only when you really
need it instead of instantiating everything at startup. When using
Gin, it is common to let the
framework inject everything for you without considering what have to
be instantiate and when. Keep in mind that Gin is just here to help
you structuring your application.
If you want to instantiate view not at startup time but while using
application consider injecting ProviderT instead of directly T. This
way you have the ability
to instantiate what you need when you need via those providers. It
will be a little bit tricker, because you will have to manager when to
instantiate your views but it's not
a Gin matter

On top of that, if I compile the application and deploy on Apache

Re: GWT and Spring - More Generation Options

2010-07-12 Thread Niel

Yes, it does use Hibernate.

The scaffolding functionality of  MyEclipse for Spring generates the
GWT front-end integrated with the Spring (Spring/JPA/Hibernate) back-
end application.  The back-end is a Spring application that uses
Hibernate as the JPA provider, and the Spring Services (@Service)
provide the RPC interface/services for the GWT front-end.  The GWT
front-end (MVP, UI Binder) is generated to call the Spring services.
The GWT portion of the application has no notion of JPA (or even
Spring for that matter).  If you are interested in Hibernate without
JPA, the back-end application can be refactored without impacting the
GWT front-end.

I hope that helps.

SmartGWT RestDataSource sample code using Spring/CXF ?

Hi All,

We've embarked on a GWT project and using SmartGWT(TreeGrid , DynamicForm,
etc) -- we found out that the open source version of SmartGWT does NOT come
with DataSources that connect to a RDBMS. In order to connect to a RDBMS, we
need to extend RestDataSource and implement REST services that provides the
CRUD in the format that the RestDataSource expects.

Are there available Java sample source code that use, say, Spring/CXF to
implement a REST service (which has CRUD operations in a RDBMS) and the
corresponding Client side GWT/SmartGWT code that interacts with the REST
Service using RestDataSource ? This will help us meet our impossible
deadline!

Re: Detecting browser in GWT 2.0.3

There *might* be a way to do it... e.g.

1. only invalidate the session on a specific log out request
2. store a flag/timestamp clientside to either invalidate the session
or not
3. onload reads this flag and decides whether or not to to invalidate
the session (if a number of seconds/minutes have elapsed)

There are/maybe security implications with this method that may mean
it's just not worth it...

You can use LocalStorage, SessionStorage and window.name etc to store/
read the flag...

Dave

Re: GWT server design

2010-07-12 Thread Raphaël Brugier

Gwt is client side, so it's just totally depends on how many numbers

You can even have no request at all, just the first download of the
application.

Re: GWT adoption

2010-07-12 Thread buz...@gmail.com

To my knowledge the adoption rate is increasing constantly. Three
years ago only enthusiasts heard of that framework. Today, every
decent developer coming to interview either heard or used GWT in a
project or prototype. But this could be only our local situation.

GWT main limitation right now is that there is no consolidated MVP,
Data Binding, Cool Widgets library, which would be available free of
charge. Version 2.1 is making things easier, but I am afraid it will
take a couple of more iterations to gets the things stabilized and
unified.

If we talk about highly interactive web-based application the solution
now is either GWT or native JS libraries on top of traditional MVC
framework like Spring MVC or Struts (just my opinion). There is also
JSF, Wicket and ZK, but they do not have the momentum of GWT. So if
you are not JS Expert and have to build Rich Internet App there are
not too many options...

BTW take a look at Vaadin. It is an alternative way of how GWT gets
further popularized.

Re: GWT adoption

The majority of what GWT can do can be done by a good web developer/
designer... but what GWT is good at is all the compile time
optimisations - when you're trying to squeeze every last bit of
performance out of of your app... and if you only/have to write Java.

It is a crutch IMHO, probably quite a good one though ;o) - but a

Re: Google Plugin for Eclipse 3.6 + Different war directory

Hm, this is definitely off; the copy should be happening for you. Just to be
clear, you're using GPE's launch configurations, right?

What platform are you on? Windows, Linux, Mac?

Other issue: it still bothers me that GPE 3.6 doesn't create the WAR

Eclipse build the project, so the directory is created, but GPE should

When you say that GPE doesn't create the WAR directory for you, do you mean
when you're using the New Web Application Wizard? Or, are you talking about

And I made a new workspace for 3.6, so I'm not sure, what's the issue, why
it isn't working...
The project is the same, I didn't created a new project for 3.6, because

So I have a sry directory where are the sources of the war files (my

Re: Problem with Eclipse, Google plugin and WTP

2010-07-12 Thread Rajeev Dayal

How are you launching your project? Do you first launch the JBoss server in
Eclipse, and then use GPE's launch configuration to launch development mode?
If so, you should edit the launch configuration and ensure that the option
Run Built-In Server is unchecked. I know this is cumbersome; we're working
to make this process more seamless in GPE 1.4.

Now I use WTP to deploy on a local JBoss, and all is working except
one thing : the libraries of project-ui are not deployed in WEB-INF/

I have found after investigating several hours I can deploy correctly
if I set in the Java Build Path (in Eclipse) the Default output
folder to build/classes (and not WebContent/WEB-INF/classes). All libs
are present in WEB-INF/lib. I can even set the folder to build/

Meanwhile I have a new error in my project :
The output directory for the project should be set to /smart-ui/

If I set the Default output folder back to WebConten/WEB-INF/classes,
I don't have the error anymore but the libs aren't exported to WEB-INF/

I think there are some incompatibilities between WTP and Google plugin

Re: GWT roadmap: easier use of REST?

GWT has a bug that prevents it from being use with Restlet.  The
Restlet framework has direct support for both Appengine, as a service

 Hi
 
 I'm currently developing some bioinformatics tools and I want to make

 The thing is that user needs to input files that might be up to 4Gb

 There are two main use-cases:
 1. Steaming the file and taking just some small parts of it to string
 2. Reading the whole file and making object from each line in file
 
 I would like to do all the file processing in client side, but I
 understood that it is not yet possible using gwt?

In general the answer is yes, but not because of GWT. Until wide-spread
browser support of HTML 5 which will provide better local file handling.

 If I keep the server local it is feasible to upload some 250mb files
 and process them at the server side, but I have no success so far in
 this, even with 10mb file.

You might provide some background on the ... no success so far... path.

For files of this size, I'd consider creating a file share on the server
or using FTP. I'm guessing the data collection occurs on the PC? If so,
you won't be able to process the files locally until HTML 5 and local
file support. Depending on your environment, you might be able to
remote-mount a disk device and write directly to that device from the
data collection source.

 So what would you suggest me to do? Besides dumping the web
 application idea and making some java applet.

You want to move the data to the server, construct a server app that
retrieves data slices on demand and sends them to the client for
rendering. You can certainly do the Java app on the server to
retrieve/preprocess the data, then render it on the client using various
graphing packages. Search this list for pointers to SVG, or graphing
libraries.

Re: GWT adoption

I think we'r missing a point here. GWT is suited for web 2.0 apps not
websites. As long as the legacy code will continue to be maintained, people
may not consider moving away from JS libs but yes for all new web apps,
GWT's team has done an awesome job of teaming up with Spring Roo guys which
will help GWT invade the market where Spring stack of technologies is widely
deployed. On the other hand, Roo's code generation may help hide the
boilerplate aspects of GWT apps. So it's a win win for GWT now.

future ( or there will be mix of other frameworks in future. If yes
than which frameworks).

I am little worried that why GWT is not adopted at a rate I would have
thought for last 4 yrs. why why...

Re: Eclipse - Google Addons are gone after update

Hi,

I spent the last hours with reinstalling eclipse and the GWT plugin
all the time, and I do not manage to get the GWT functionality back
into eclipse. My GWT projects are shown with a red exclamation mark
and there are not GWT menu items.

I am running Debian 5.0.4 with the newest eclipse 3.6 (Helios), which
I downloaded from www.eclipse.org.

For the upgrade I did exactly what is documented on code.google.com:
Help - Install new software: http://dl.google.com/eclipse/plugin/3.6

Thanks for the hint with the error log: It says that the plugin is
already installed. However, when I reinstalled eclipse, I deleted the
eclipse directory (/usr/local/eclipse) as well as the local
configuration (.~/.eclipse). I do not know why the message appears
that the plugin is already installed...

Please help! I want to continue with my GWT projects! .-)

Re: Dependency injection perf issues

If you compile GIN from TRUNK, you will find a new AsyncProvider
interface... thats the result of a GIN PROVIDER + RUNASYNC

2010/7/12 david.herv...@gmail.com david.herv...@gmail.com

Hi,

the fact that you are using DI does not change your startup time. Your
application will take approximately the same time to load if you does
the injection by hand.
Actually, I think you want to create your view only when you really
need it instead of instantiating everything at startup. When using
Gin, it is common to let the
framework inject everything for you without considering what have to
be instantiate and when. Keep in mind that Gin is just here to help
you structuring your application.
If you want to instantiate view not at startup time but while using
application consider injecting ProviderT instead of directly T. This
way you have the ability
to instantiate what you need when you need via those providers. It
will be a little bit tricker, because you will have to manager when to
instantiate your views but it's not
a Gin matter

regards

Now it seems that if I use DI than all views are generated at web app
intial start time in browser. Thus start time becomes slow. Am I
right? ( I think I heard something like this before also but just want
to validate).

So if above is true than using @Inject is no good .. right? ( or where
can we use @Inject ).

Can we use use @Inject to lazily create views instead of web app start
time?

MVP Problem when implementing the presenter as singleton

2010-07-12 Thread crojay78

Hi,

I have a problem with my mvp project.

I do the binding in the constructor of each presenter, every presenter
is implemented as a singleton. I do that because otherwise I
discovered that the binding to the buttons, textboxes etc will be
established each time I use the presenter and so i had duplicated
actions. Now the bind method will be called only once like excpected
but when I click a button in my view there no action, its like the
binding to my buttons does not exist? Does anyone has an advise for
me? I do not see the issue? Or is it not possible to do that in gwt ?


Thanks

Reusability of GWT UI

MVP multiple buttons/fields

2010-07-12 Thread Fendy Tjin

Hi, I would like to elegantly code my application. I am rather
confused as to how to code for multiple button/field.

such as: multiple delete buttons, or multiple update text fields

I have a working sample of it, however it is very messy and I would
like to know if there is any other way to do it.

Currently my code is as such:

SomePresenter.java

// some code
private void addStock(JsArrayStock stocks) {
FlexTable viewStockTable = new FlexTable();
viewStockTable.removeAllRows();
viewStockTable.setText(0, 0, Symbol);
viewStockTable.setText(0, 1, Name);
viewStockTable.setText(0, 2, Price);
viewStockTable.setText(0, 3, Change);
viewStockTable.setText(0, 4, Remove);
int row = 1;

for (int i = 0; i  stocks.length(); i++) {
  viewStockTable.setText(row, 0, stocks.get(i).getCode());
  viewStockTable.setText(row, 1, stocks.get(i).getName());
  viewStockTable.setText(row, 2, $  +
roundDouble(getPrice(stocks.get(i).getStockPrice(), 0), 2));
  viewStockTable.setText(row, 3,
roundDouble(getPriceChange(stocks.get(i).getStockPrice(), 0), 2) + 
%);
  Button removeButton = new Button(x);
  final String code = stocks.get(i).getCode();

//Here is the problem--
  removeButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
  deleteStock(code);
}
  });
//
  viewStockTable.setWidget(row, 4, removeButton);

  row++;
}
display.addStock(viewStockTable);
  }

SomeView.java

private DecoratorPanel leftPanel = new DecoratorPanel();
private VerticalPanel leftStack = new VerticalPanel();
private SimplePanel viewPanel = new SimplePanel();
private FlexTable viewStockTable = new FlexTable();

public HomeView() {
 //... some code

// assemble left panel
leftStack.add(addPanel);
viewPanel.add(viewStockTable);
leftStack.add(viewPanel);
leftPanel.add(leftStack);

//... some code
  }

//... some code

public void addStock(FlexTable table) {
viewPanel.clear();
viewPanel.add(table);
// -- Can't be done unless I put it in another container
like the panel ---
// viewStockPanel = table;
//
--
  }

My structure:
SomePresenter.java
  - addStock method - retrieve data from rpc then is creates the table
to view and pass the table to SomeView.java

I also do not like all the buttons are created in the view, if so what
is the point of MVP while I can also create them in Model and
Presenter alone. Since I created all the buttons in the Presenter,
when I pass the table to View, It can't be done with (viewStockTable =
table).

I do not like this is structured, is there another way to do it?

Thank you.

Re: Eclipse - Google Addons are gone after update

But:

starting them with Run As Web Application results in:

Re: Client OR mapping

2010-07-12 Thread Stefan Bachert

Hi,

the client does not know about OR at all. There is NO WAY to lazy load
something. The client only know objects.

In a real good client architecture a view/control works against a
model proxy in the client (sometimes I call them client object cache)
Either the model object is already in the cache or it will be
requested.
In such an architecture the use of comet/server-push techniques is
essential.
You could decide on server side which strategy regarding a certain
model object is the best (eager supplying dependent object too, or
not )
However, feeling well in the async world is a prerequisite

 Thus do you manually map objects again in client ( or do you store
 CUSTOMER, ORDER, ITEM  in separate shared variables or something
 else.).

 I am sure you experts out there must have some directions for us.

in general a full AJAX web application (as GWT is one) do generate

 How do two different MVP widgets share VIEW data ( for example if

 Again, all widgets are designed using MVP and send events using

Re: Client OR mapping

Thanks for response. However may be my question was misleading and
thus I did not get the answer.

My question is how do you maintain mapping between Model objects at
client

Say for example, over the course of user conversation, there were
three DIFFERENT ajax calls to load CUSTOMER, ORDERS and ITEMS.

Now do you manually map CUSTOMER to ORDER and ORDER to ITEM in client
after data is received from server, to maintain mapping between Model
objects
( or do you store CUSTOMER, ORDER, ITEM  separatly with no mapping or
there is a framework which maps obejcts with configuration like
hibernate mappings in client)

thanks

  fetching only).

  Thus do you manually map objects again in client ( or do you store
  CUSTOMER, ORDER, ITEM  in separate shared variables or something
  else.).

  I am sure you experts out there must have some directions for us.- Hide

Re: TablayoutPanel - how to align tabs on right (top)

Hi,
I assume, by rtl, you meant right-to-left. Then, no, my UI designer gave me
this design to have the tab-headers on the right.
I do not want to go back to UI-designer that its not possible, unless I have
tried my options.
thanks,

The Music Collective, a GWT project

2010-07-12 Thread charlie

Hi all!

So I'm launching my first GWT app,
http://www.the-music-collective.com/listen/MP3Player.html .  A year ago
pandora started charging for more than 40 hours a month, so I decided to
write an online mp3 player that I could upload my music to once and listen
to wherever.

It's since become an sort of social networking meets music app, where you
invite friends, they 'like' songs, and you can get a glimpse of what
everyone is into, music wise, at the moment.

One interesting aspect was this deferred login / sign up.  The application
only prompts you for login / signup when you try to do something that
requires you to be logged in.  This was an after thought, but thanks to how
GWT is setup, it required little to no changes at all.

So, what have you built with GWT?  Share!

Re: The Music Collective, a GWT project

2010-07-12 Thread Nabeel Ali Memon

Nice app. Have you opened up the source?

To have some fun time, I had created this tiny amateur project I named
Gwt-Presentations. I actually had to deliver an internal (workplace) talk on
Maven 101 so I thought maybe I should create a simple clean presentation
in GWT and code my slides in Java to convert my boredom into fun ;)

The source is open for all
http://github.com/nabeelalimemon/Gwt-Presentations and everybody is welcome
to contribute and/or criticize. Remember, it's just targeted for some fun
and it's, currently, suitable only for creating some simple presentations.
To improve the quality, cleanup things and make it a nice sample GWT 2 app,
i plan to implement MVP, DI, UIBinder stuff into it. Currently if you wanna
try it, you may read the project's wiki page.

Re: Passing data between modules - MVP architecture

2010-07-12 Thread lineman78

May I also suggest that you look at an approach based on GWT exporter
so you can make calls between the modules directly.  I have been
playing around with making a GWT based plugable portal architecture
based on this approach and have been partially successful in my
limited experimentation.

On Jul 9, 9:35 am, grandanat marian.strug...@gmail.com wrote:
 Hello all.
 I Have a simple scenario:
 -a GWT application with an application controller that handles history
 and initialize modules. ( a module is an entity formed by a presenter
 + view - classic MVP, nothing special)
 -from a module should be opened another module and pass init data to
 it, and then after child module finishes its job to return another
 response data.

 I followed two approaches and i would like to comment them.

 1.eventBuss approach - pass data within events.
 i have StartChildModuleEvent event that encapsulates a module parent
 ID, and some init data, and an ExitChildModuleEvent event that
 encapsulates some return data.

 2 callback approach.
 i added to my modules a callBack handler

 public abstract class ModuleCallBackHandlerD, T implements
 DataCallBackHandlerT {

   private ModuleID parentID;

   private D initData;
   private T returnData;

   public ModuleCallBackHandler(ModuleID parentID) {
     this.parentID = parentID;
   }

   public ModuleCallBackHandler(ModuleID parentID, D initData) {
     this.parentID = parentID;
     this.initData = initData;
   }

   public void onCancel(){
   }

   public void onFailure(Throwable caught){
     Window.alert(AppGin.injector.getAppConstants().msg_moduleError() +
  :  + caught.getMessage());
 //    caught.printStackTrace();
   }

   public ModuleID getParentID() {
     return parentID;
   }

   public D getInitData() {
     return initData;
   }

   public T getReturnData() {
     return returnData;
   }

 }

 and when i want to init a child module i instantiate a new callback

 AppGin.injector.getAppController().doStartChildModule(ModuleID.ITEMSEARCH,
             new ModuleCallBackHandlerString, Item(getModuleID(),
 itemID) {

               @Override
               public void onSuccess(Item result) {
                 //do some stuff - update this module with received
 data
               }

             });

 I would like some opinions regarding this two approaches.

 Thanks all

Re: concerns on 2.1 MVP approach

2010-07-12 Thread Thomas Broyer



On 12 juil, 19:34, PhilBeaudoin philippe.beaud...@gmail.com wrote:
 Following an off-group discussion with Marius, he suggested that I
 comment back on this thread regarding the fear of many gwt-platform
 users and developers that the GWT MVP approach is too tightly linked
 to SpringRoo and the idea that it can generate a lot of boilerplate
 automatically. Do you think this apprehension is grounded, or that
 GWT's MVP can lead to lean code even when written manually?

First, it's a stated goal that RequestFactory/ValueStore is usable
easily enough without tooling such as Roo:
https://wave.google.com/wave/waveref/googlewave.com/w+WU4iAICkI
Key phrase: this is definitely intended to be useful without Roo

That being said, when you have many model objects, coding the as-many
Record interfaces and the @Service interfaces on the client-side is
cumbersome. This is going to change a bit though: M1 required a
ServerOperation enum for each @Service interface and a server-side
Config, M2 removes this using reflection on the server-side (as the
default implementation, because it's pluggable), and the goal is to
remove even more (The Property types are cumbersome and we plan to
drop them).
We're starting prototyping, so it's OK to code those things by hand
(and play by the current limitations: I'm coding a server-side object
extending a model object just to add the findXxx, persist and remove
methods), but if it proves necessary (or just worth it), we'll use
generators, probably in the form of an annotation processor.
(FWIW, we're using Morphia on the server-side to persist POJOs into
MongoDB, which is quite similar what Objectify is for AppEngine
AFAICT)

Time will tell if RequestFactory fulfills its stated goal of being
easy enough to be used without Roo, but it's promising and I guess
only feedback from the community will help make it useful in as many
contexts as possible (proof that Gogle is listening: the
RequestFactoryServletHelper answers an early user request)

Re: MVP multiple buttons/fields

Start moving the code of addStock to the view. Try not to use widget code on
the presenter.

Then create an interface and implement in the presenter:
class SomeViewHandlers {
void deleteStock(Stock code);
}

You already have the deleteStock method... so just add implements
SomeViewHandlers to it.

Then you need to give to the display that interface (generally in the
constructor):
display.setViewHandlers(this);

Then in the presenter lease the method as:
private void addStock(JsArrayStock stocks) {
display.addStock(stocks);
}

And in the view copyPaste the code of the method and change this:
 removeButton.addClickHandler(new ClickHandler() {
   @Override
   public void onClick(ClickEvent event) {
 *viewHandlers.*deleteStock(code);
   }
 });

Best

2010/7/12 Fendy Tjin fendyt...@gmail.com

 Hi, I would like to elegantly code my application. I am rather
 confused as to how to code for multiple button/field.

 such as: multiple delete buttons, or multiple update text fields

 I have a working sample of it, however it is very messy and I would
 like to know if there is any other way to do it.

 Currently my code is as such:

 SomePresenter.java

 // some code
 private void addStock(JsArrayStock stocks) {
FlexTable viewStockTable = new FlexTable();
viewStockTable.removeAllRows();
viewStockTable.setText(0, 0, Symbol);
viewStockTable.setText(0, 1, Name);
viewStockTable.setText(0, 2, Price);
viewStockTable.setText(0, 3, Change);
viewStockTable.setText(0, 4, Remove);
int row = 1;

for (int i = 0; i  stocks.length(); i++) {
  viewStockTable.setText(row, 0, stocks.get(i).getCode());
  viewStockTable.setText(row, 1, stocks.get(i).getName());
  viewStockTable.setText(row, 2, $  +
 roundDouble(getPrice(stocks.get(i).getStockPrice(), 0), 2));
  viewStockTable.setText(row, 3,
 roundDouble(getPriceChange(stocks.get(i).getStockPrice(), 0), 2) + 
 %);
  Button removeButton = new Button(x);
  final String code = stocks.get(i).getCode();

 //Here is the problem--
  removeButton.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
  deleteStock(code);
}
  });
 //
  viewStockTable.setWidget(row, 4, removeButton);

  row++;
}
display.addStock(viewStockTable);
  }

 SomeView.java

 private DecoratorPanel leftPanel = new DecoratorPanel();
 private VerticalPanel leftStack = new VerticalPanel();
 private SimplePanel viewPanel = new SimplePanel();
 private FlexTable viewStockTable = new FlexTable();

 public HomeView() {
  //... some code

// assemble left panel
leftStack.add(addPanel);
viewPanel.add(viewStockTable);
leftStack.add(viewPanel);
leftPanel.add(leftStack);

 //... some code
  }

 //... some code

 public void addStock(FlexTable table) {
viewPanel.clear();
viewPanel.add(table);
 // -- Can't be done unless I put it in another container
 like the panel ---
 // viewStockPanel = table;
 //

 --
  }

 My structure:
 SomePresenter.java
  - addStock method - retrieve data from rpc then is creates the table
 to view and pass the table to SomeView.java

 I also do not like all the buttons are created in the view, if so what
 is the point of MVP while I can also create them in Model and
 Presenter alone. Since I created all the buttons in the Presenter,
 when I pass the table to View, It can't be done with (viewStockTable =
 table).

 I do not like this is structured, is there another way to do it?

 Thank you.

reliability and repeatability) the releases of GWT not being available
in central within a day or two of release is an incredible pain in the
backside and a very negative image for GWT in corporate. We are
suffering this Safari problem and now I'm going to have to manually
insert these artefacts into our repository.

This is *not* hard, Sonatype have been really good about making this
straight forward. Who is responsible for doing this and who has done
it in the past? Whoever you are, if you can't do it quickly I
volunteer to take over the responsibility for it and make sure it is
in within a couple of days. If I get to do it it, I'll also create a
new googlecode repository for the nightlies for people to version
range over if they wish.

gwt-html5-persistence: GWT client side persistence

2010-07-12 Thread Dennis Z Jiang

Hi everyone,

I am working on an GWT generator project that enables objects to be
persisted on the client side html5 database (or Google Gears db). The
generator is a wrapper of a JavaScript library that provides the
actual object persistence functionality. If you have need to persist
objects on the browser database, you are welcome to visit the project
site for more details.

http://github.com/dennisjzh/gwt-html5-persistence

The sample code below demonstrates how to persist objects to the
browser database. The sample creates five task objects, persists them,
and then retrieves the ones that are marked as done. No SQL statement
is used in the code.

final EntityTask taskEntity = GWT.create(Task.class);
final EntityTag tagEntity = GWT.create(Tag.class);
final EntityCategory categoryEntity = GWT.create(Category.class);

Persistence.schemaSync(new Callback() {
public void onSuccess() {
final Category c = categoryEntity.newInstance();
c.setName(Main);
final Tag tag = tagEntity.newInstance();
tag.setName(Urgent);
for (int i = 0; i  5; i++) {
Task t = taskEntity.newInstance();
t.setName(Task + Integer.toString(i));
t.setDescription(Task No # + Integer.toString(i));
t.setDone(i % 2 == 0);
t.setCategory(c);
t.getTags().add(tag);
}

Persistence.flush(new Callback() {
public void onSuccess() {
CollectionTask allTasks =
c.getTasks().filter(Done, ==, true);
allTasks.list(new CollectionCallbackTask() {
public void onSuccess(Task[] results) {
for (Task task : results) {
RootPanel.get(taskNameContainer).add(new
Label(task.getName()));
}
}
});
Persistence.reset();
}
});
}
});

Re: Exception thrown when running on Google Chrome w ith compiler output style set to ‘OBF’

2010-07-12 Thread dob...@gmail.com

Hello,

I made a jar that is able to replace all occurrences of a regular
expression of a file or file extension. It can be called using pom.

A example:

C:\wde\jvm\jdk5\bin\java -jar RegularReplacer1-5.jar C:\wde\eclipse-
workspaces\main\ria\target\webb-2.0\br.com.webb.ria.Application
.cache.html ([^a-zA-Z0-9_])top\(( $1topazio\(

This will replace all the occurrences of top( by topazio(, in
the .cache.html files in the C:\wde\eclipse-workspaces\main\ria\target
\webb-2.0\br.com.webb.ria.Application directory.
Webb 2-0 is our project. You should point it to the place that GWT
generates yours .cache.html files. Of course, it could be used for
more things.

Using it with pom.

I made this code, and it is free and open source.

 Ya, I would seriously suggest upgrading to the GWT 2.0.1 because so
 many tiny little bugs have been fixed over all the releases. You'll
 have to start a new project and copy your code over to deal with the
 structure changes and other little stuff that changed in the project
 since GWT 1.5. It's not very hard to convert an app to a new project
 with a newer GWT. Most of the deprecated code still works I'm pretty
 sure. Event listeners and all that still work.

   I'd like to know if you guys have faced the same problem I'm facing,

   Sometimes, a small and harmless change in a Java class ensues strange
   errors at runtime.

   These errors only happen if BOTH conditions below are true:

   2) the application is run on Google Chrome, and

   1) the GWT JavaScript compiler output style is set to 'OBF'.

   So, running the application on Firefox or IE always works.
   Running with the output style set to 'pretty' or 'detailed' always
   works, even on Google Chrome.

   Here's an example of error message that I got:

       ((TypeError): Property 'top' of object [object DOMWindow] is not
   a function stack

   And here's what I have:
   - GWT 1.5.3
   - GXT 1.2.4
   - Google Chrome 4 and 5
   - Windows XP

   In order to get rid of this Heisenbug, I have to either deploy my
   application without obfuscation or endure a time-consuming trial-and-
   error process in which I re-implement the change in slightly different
   ways and re-run the application, until the GWT compiler is happy with
   my code.

   Would you have a better idea on how to avoid this?

  Which GWT version are you using?
  This seems related 
  tohttp://code.google.com/p/google-web-toolkit/issues/detail?id=4117
  but it seems to me that this was fixed in GWT 1.6

Re: Eclipse - Google Addons are gone after update

Hi Rajeev,

I always installed eclipse as root, i. e. extracting the tar archive
as root into /usr/local/eclipse and changing the ownership of all
files and folders to root.

I always used eclipse as a normal user by calling /usr/local/eclipse/
eclipse.

I always install new eclipse plugin within eclipse running as a normal
user.

This always worked, except with the GWT plugin. I would be glad if I
knew why...

You shouldn't need to change the ownership. If you're really extracting the
files as root, then they are already owned by root.



 I always used eclipse as a normal user by calling /usr/local/eclipse/

May I recommend using update-alternatives? You can keep several Eclipse
versions side-by-side

For example:
sudo mv /usr/local/eclipse /usr/local/eclipse-3.6
sudo update-alternatives --install /usr/bin/eclipse eclipse
/usr/local/eclipse-3.6/eclipse 100
.
.
.
sudo mv /usr/local/eclipse /usr/local/eclipse-3.7
sudo update-alternatives --install /usr/bin/eclipse eclipse
/usr/local/eclipse-3.7/eclipse 150

then

sudo update-alternatives --config eclipse

to switch among the alternatives

That's probably the source of the problem, Install the plugin as root.
Always update Eclipse as root.

This means starting Eclipse as root, and running add new software

When working w/ Eclipse day-to-day, run Eclipse as magnus:magnus or
magnus:users

I generally turn off check for updates when running as a normal user.
Every few weeks, I'll check for eclipse updates, although there are usually
posts on relevant lists (subversion, gpe, epic...)


 This always worked, except with the GWT plugin. I would be glad if I

I think that 3.6 tightened up on some permissions. I'm not really sure.

However, I'm now running eclipse using a local initialization file to get
around a new osgi-related locking issue.

eclipse --launcher.ini /home/jchimene/.eclipse/eclipse.ini 

Frankly, I like this better, as I leave /usr/local pristine.

  Probably one gif is smaller than the limit but the other is NOT.

 that seems to be the cause. However, only one out of four images in
 the resoucebundle is (slightly) larger than 32k, the others are
 smaller and still not displayed.

  For debugging just compile with output style: detailed. This gives

 Actually, I check the browser version and use setUrl() in case that it
