 Surprisingly was unable to find any prior discussions about this...

 I'm optimizing my app's load time by merging all my stylesheets into a

 number of HTTP requests.  I'd like to also concatenate all the
 stylesheets from third party libraries I'm using into this single CSS
 file, but don't see a way to undefine the stylesheet module XML
 elements in these third party modules.

 For example, I'm using Fred Sauer's gwt-dnd library, whose module XML
 contains

 stylesheet src=gwt-dnd.css/

 This line instructs the browser to request gwt-dnd.css when this
 module is loaded, but I don't want this to happen.

 Any ideas?

Don't do it by hand, write a linker to be run before the primary
linker (@LinkerOrder(Order.PRE)) that'll process all artifacts.find
(StylesheetReference.class) and replace them with a single
StylesheetReference while emitting the new single CSS file.

Re: At new item to a list at each position

2009-08-18 Thread Tobe


I had AbsolutePanels with other Widgets added to it, but now I just
have one Widget in each. In other cases I used VerticalPanels instead
of AbsolutePanels to get access to the different Widgets in the rows.
Unfortunately I can't get the Widget of a Widget e. g. when I have a
ListBox inside a VerticalPanel and the VerticalPanel inside a
FlexTable by using flextable.getWidget(1,0).getWidget(0);, but it
works when I get the Widgets step by step and cast it in each step.

  Ok, but in this case inside the (1,0) there can be some more Elements

   You have an outer table with 'Insert' buttons in the even rows
  (0,2,4,...)
   and child tables in the first column of the odd rows (1,3,...)

   To access the first child table, you use

   FlexTable inner = (FlexTable)outer.getWidget(1, 0);

Wrap TextBox with span

2009-08-18 Thread Dominic


Hi

We would like to extend the gwt TextBox such that it is wrapped by a
span. The reason for this is  to integrate a validation icon. The
rendered html should look something like this:

span class=my-TextBox style=
input class=text type=text/
div class=validationIcon/
/span

How can we achieve this?

Regards,
Dominic

Re: Localization workflow?




On 18 août, 06:38, Dobes dob...@gmail.com wrote:
 What tools are people using for localization?

 For example, currently I've defined all my strings using @DefaultValue
 (...) for my Constants interface instead of a properties file - is
 there a tool out there to convert an interface into a properties file,

Add a @Generate(format =
com.google.gwt.i18n.rebind.format.PropertiesFormat) attribute to
your Messages or Constants interface and then just compile your
project (if using GWT 1.6 or higher, pass the -extra argument with the
target directory as the value) and it'll generate the properties file
from the interface (if using GWT 1.5, in the www/module-aux
directory).

 or validation a properties file against and interface?

AFAICT, you'll have exceptions if a key isn't translated, so there's
some kind of validation built-in when you compile the project.

 Has anyone seen a tool to take all the properties from the interface
 including the @Meaning annotations and generate/update and excel
 spreadsheet from that with columns Untranslated, Meaning, ID?
 This could be used as the first step of the translation workflow.

 Next I could merge this file with any prior translations by detecting
 any rows where the Untranslated or Meaning has changed or added
 and produce a new Excel file with additional columns Old
 Untranslated, Old Meaning, and Old Translation.  This file can be
 sent to the translators for translation, who would be responsible for
 filling in the translation column only.

 When it comes back I need another tool to extract the ID and
 Translation column data and dump that into the appropriate .properties
 file.

 I'm thinking I'm not the only one who needs to create and update
 translations of their GWT app, but so far my Googling hasn't turned up
 any tools for this - especically the first step where the interface
 IDs and meanings are extracted out into a useful format.

 Anybody got anything to help with this?

We're in the process of translating our app (read: imported the
generated properties file into an Excel sheet –just key/default
message, as we do not (yet) use @Meaning et al.– and have it
translated, translations not yet turned back into a properties file)
so I guess the answer is not yet, but I'm definitely interested in
whatever you could find about it.

Re: GWT 1.7 compiles null.nullMethod() into javascript for HTMLTable sub-class




On 18 août, 01:30, Bob The Cheese bobtheche...@gmail.com wrote:
 OK, so I'm making a custom type of table which manages a datastore,

 in particular this line:
 td = null.nullMethod();

 I've looked around, and can't find anything which really explains to
 me what's going wrong.

Looking at the equivalent method in Java world:
  public void setHTML(int row, int column, String html) {
prepareCell(row, column);
Element td = cleanCell(row, column, html == null);
if (html != null) {
  DOM.setInnerHTML(td, html);
}
  }
...
  private Element cleanCell(int row, int column, boolean
clearInnerHTML) {
// Clear whatever is in the cell.
Element td = getCellFormatter().getRawElement(row, column);
internalClearCell(td, clearInnerHTML);
return td;
  }


It looks like getCellFormatter() always return 'null' so the compiler
translated the getRawElement(row,column) into 'null.nullMethod()' to
cause a null pointer exception equivalent in JavaScript.

What it means is that you never ever called setCellFormatter(...)

Re: Allow other domains to access a GWT application (running on Google App Engine)




On 18 août, 01:08, Everett everett.to...@gmail.com wrote:
 Hi All,

 I would like to allow a particular set of other domains to access my
 GWT application (running on Google App Engine).  Is this possible with
 GWT and how to do it?

 For example:

 Let's say I have the StockWatcher application from the tutorial
 running onhttp://stockwatcher.appspot.com.  Part of the page
 StockWatcher.html are the lines

 link type=text/css rel=stylesheet href=StockWatcher.css
 ...
 script type=text/javascript language=javascript src=stockwatcher/
 stockwatcher.nocache.js/script

 The application is run ashttp://stockwatcher.appspot.com/StockWatcher.html
 and everything works fine.

 Now let's say I want to also allow example.com to run my StockWatcher
 application.  I tell them to make a copy of StockWatcher.html in their
 root directory and change the lines above to

 link type=text/css rel=stylesheet href=http://
 stockwatcher.appspot.com/StockWatcher.css
 ...
 script type=text/javascript language=javascript src=http://
 stockwatcher.appspot.com/stockwatcher/stockwatcher.nocache.js/
 script

 The application is run ashttp://www.example.com/StockWatcher.html
 and, ideally, everything works fine.

 I tried a scenario similar to this but when I 
 viewedhttp://www.example.com/StockWatcher.htmlI didn't see the StockWatcher
 application and no errors were reported.  When I view the source of
 the page everything looks fine to me.

 My questions are:

 1. Is this kind of application deployment possible in GWT?

yes, provided the app doesn't talk to the server using GWT-RPC or
similar (Google for same origin policy to understand why) or the
domain where the app runs also runs a proxy (the app calls the
proxy at the same origin, which relays the requests to your AppEngine
app, therefore bypassing the SOP restriction)
In the near future, browsers will implement CORS http://www.w3.org/TR/
cors which will enable safe cross-origin requests (similar to Flash
and IE8's XDomainRequest), but for now you'll have to go the proxy
way (or use ugly hacks such as JSONP and/or post form to hidden
iframe which then sets window.name)

 2. If so, how would you go about doing it?  I'm a developer new to GWT
 so I just need a kick in the right direction.

Add add-linker name=xs / (it's known as the cross site linker)
to your module's gwt.xml to generate *.cache.js instead of
*.cache.html; that way it won't use an iframe and won't face the same-
origin policy that have been blocking you in your experiment. But your
app will run in the context of the page instead of being sandboxed
in an iframe, which means that if another script modifies, say, the
Array object, you might run into troubles (this is not quite likely
but it's still a possibility).
I think the choice of GWT to run within an iframe by default also has
to do with caching wrt IE (or was it Firefox?) and/or HTTPS, which
caches *.html well but won't cache *.js...

 3. How would you get the example.com domain to check it against a
 whitelist of allowed domains in the GWT application?

In your app, in onModuleLoad, check that Window.Location.getHostName()
is what you expect.

Re: GALGWT, Eclipse 3.5 / Galileo, and GWT 1.7 -- how to add this or any other GWT library to projects?

2009-08-18 Thread philipmac


right, everything looked like it should be ok, compiled completely
without warning, but somehow hosted mode only worked with the

I was wondering though why the gears GWT stuff is not distributed as a

for this but it would be nice to have it all as slick as the core
GWT.
Or is that just being greedy?

GWT1.6.4 multiple module and gwt-ext

2009-08-18 Thread Vlad


When putting multiple GWT modules on the html host page that use gwt-
ext library there is JavaScript error and only in the OBFuscated mode.
Everything works just fine in the PRETTY mode. Most likely the error
is caused by the name collision in the obfuscated mode when method aa1
() from one module collides with the same obfuscated name from the
second one. Basically when first module executes some method there is
an error and stack trace reference to the HTML file from the different
module.

Is there any way to specify some range for JavaScript method names
when compiling in the OBFuscated mode via linker etc.

Thanks.

Server side

2009-08-18 Thread Alexei Telles


Hello guys.

I'm trying finally to make my GWT application works client and server
sides.
I have a simple service (just one method for now).

This method, on the server side, uses a Jar file (created for me) to
connect in my database (MySql) using hibernate.

I am having a problem to use hibernate (the java method that uses
hibernate is in the jar file - that is in the class path of my GWT
project).

It throws me an exception when I am configuring hibernate
SessionFactory sessionFactory = new Configuration().configure
(guardian.hibernate.cfg.xml).buildSessionFactory();

I don't know if you guys use hibernate, but I am sure this problem is
in my GWT project, because if I create a basic java project and try to
use this Jar file (that uses hibernate) everithing works fine.

The exception is:

 worked, though I did not have a server-side component.  I'm not sure what
 the noredist does not contain, but if you notice strange behavior, you may
 want to try with regular gwt-gears.jar on a clean project.

 Good news everyone!

 So, I was wondering why there is two gears jars, one called gwt-gears-
 noredist.jar and one called gwt-gears.jar.


 Well, instead of adding gwt-gears.jar to the project, I added gwt-
 gears-noredist.jar.
 The above seems to work now.
 I shall have to test the db functionality now.

2009-08-18 Thread Saurabh Naik

Hello..

 I want to use suggestionbox and data should be added dynamically
from database. so for that I am going to use JSON.
but I am not getting how to do that. I also searched for this kind of
example.. but in every example data is hardcoded in suggestionbox so can any
one give me the idea for that


Thanks

Re: Wrap TextBox with span

2009-08-18 Thread jwheat3300


From the look of your html code, your validation icon will continue to
be placed below your input because you are using a div as your
container for the icon. For GWT you can make this work by using a
HorizontalPanel, so basically you will have.

HorizontalPanel panel = new HorizontalPanel();

TextBox box = new TextBox();
box.setStylePrimaryName(text);

SimplePanel divPanel = new SimplePanel();
divPanel.setStylePrimaryName(validationIcon);

panel.add(box);
panel.add(divPanel);

This will get you to where you want to go, but there are other options
such as a FlowPanel or you could also use the InlineHTML widget.The
InlineHTML widget wraps text or html in a span. So you could also do:

InlineHTML html = new InlineHTML();
html.setStylePrimaryName(validationIcon);

Then add it to the panel that contains your TextBox.

Hope this helped.

 Hi

 We would like to extend the gwt TextBox such that it is wrapped by a
 span. The reason for this is  to integrate a validation icon. The
 rendered html should look something like this:

 span class=my-TextBox style=
     input class=text type=text/
     div class=validationIcon/
 /span

 How can we achieve this?

Re: generics, events, dependency injection

2009-08-18 Thread Eugen Paraschiv


Quick question...when you say provider, what do you mean exactly? Is
there a specific provider method pattern?

   Hi all.

   I've been trying to get a nice setup of the best practices presented
   at google i/o. I have something working, but a few questions.

   The first one is how fine-grained do you go for the events you define?
   Say i have events for updates in entities A and B in my model:
   UpdatedAEvent, UpdatedBEvent. To prevent creating new event classes
   for every entity i might add, i liked the idea of usinggenericsafter
   looking at the source code of GWT.

   Classes like:
   public class ModelUpdatedEventV extends
   GwtEventModelUpdatedHandlerV {
   ...
   private static TypeModelUpdatedHandler? TYPE;
   ...
   public static TypeModelUpdatedHandler? getType() {
     if (TYPE == null) {
       TYPE = new TypeModelUpdatedHandler?();
     }
     return TYPE;}

  I'd rather write:
  @SuppressWarning(unchecked)
  public static V TypeModelUpdatedHandlerV getType() {
     return TYPE;

  }

  (TYPE might have to be of type Type?)

  (Given that you most probably won't use ModelUpdatedEvent without its
  TYPE, you can just initialize it in the declaration, like GWT does,
  and have getType() just return TYPE)

   But then i guess i can't use them with an event bus (the
   HandlerManager)? I lack complete understand ofgenericsand wildcards,
   but assuming the class doesn't know the type, this won't work right?

  Even if the class did use V, it wouldn't work, becausegenericsin
  Java are hardly more than just syntactic sugar (google for 
  javagenericserasure).

   eventBus.addHandler(ModelUpdatedEvent.getType(), ...)

  However you write ModelUpdatedEvent/ModelUpdatedHandler, you'd end up
  having all your handlers receive all ModelUpdatedEvent? events.

  The only way you could make this work is having a getType(Class?
  cls) returning a different TypeModelUpdatedHandler? instance for
  each class given as argument:

  public static V TypeModelUpdatedHandlerV getType(ClassV cls) {
     // do your magic here}

  ...
  eventBus.addHandler(ModelUpdatedEvent.getType(A.class), ...);

  ...or you could instead have a getTypeForA() and getTypeForB()
  methods:
  public static TypeModelUpdatedHandlerA getTypeForA() { return
  TYPE_A; }
  public static TypeModelUpdatedHandlerB getTypeForB() { return
  TYPE_B; }

  ...this wouldn't be that different from having a ModelUpdatedEvent
  subclass per model class.

 Thanks for your reply. I've done this (multiple subclasses), but was
 looking for a better option.



   The second point is regarding dependency injection. I got it working
   for things implementing interfaces, to which i bind implementations.
   But how do you go for the HandlerManager for example? I've tried
   making it a singleton as in:
       protected void configure() {
           ...
           bind(HandlerManager.class).asEagerSingleton();
           ...

   but i get No @Inject or default constructor found for class
   com.google.gwt.event.shared.HandlerManager.

   Same if i use .in(Singleton.class). I've seen that GWT should fallback
   to GWT.create when there's no injection available, but if i don't
   mention the HandlerManager in my injector it also fails.

  ...and GWT.create() expects a default constructor.

  The solution IMO is to use a provider.

 Provider it was (as in provider method), it worked fine.

 Thanks again,
 Ricardo

Implementing the HasLoadHandlers interface

2009-08-18 Thread Tamás Gömbös

Greetings Everyone!

I am relatively new to web development and I started to use GWT just a few
days ago.

I have the following problem:
The ListBox widget does not implement the HasLoadHandlers interface and I
have a ListBox that I would like to load with some data from a server. I
extended ListBox as class LoadableListBox. I searched for some examples and
created the code below:

public class LoadableListBox extends ListBox implements HasLoadHandlers{

public HandlerRegistration addLoadHandler(LoadHandler handler) {
return addHandler(handler, LoadEvent.getType());
  }

@Override
 public void fireEvent(GwtEvent? event) {

 }

}

I have another class which implements the LoadHandler interface and
overrides its void onLoad(LoadEvent event) method. With the code above, the
LoadableListBox on the page does not load.
What is the correct way of implementing a HasXXXHandlers interface?

Thank you very much for your help,
Tamás Gömbös


P.S.: Alternatively, I tried to load the data into the widget via its
parent's void onLoad() method and it doesn't load the ListBox when I open
the page, only if I reload it. I suppose this is because of the
client-server mechanism or something like that. I don't go into details in
this case, because I think the correct way is the former.

Hi to all,

I am new to GWT. I read GWT communication with server tutorial. It
provides various mechanisms to communicate with the server. Any way i
know how to use GWT RPC and HTTP mechanism to communicate with
server.

I request all of you can you give perfect explanation to when should
we use RPC mechanism and when should we use HTTP mechanism. I mean at

Confused about GWT + App Engine

2009-08-18 Thread mthakershi


Hello,

I have been studying and trying GWT for 2 weeks now. I love it. So I
decided to start building something useful.

Now, I came across google app engine. For someone, who just wants to
build something to learn this sounds like a very good place to install
applications without spending $$$ for hosting and other resources.

App engine provides data storage, authentication and hosting.

GWT will give me ability to manipulate DOM using Java at the same time
communicate with server-side.

But is it possible to use GWT in JSP pages that are hosted on App
Engine? I am confused about what will take precedence.

I am sorry if my question sounds stupid but GWT and App Engine are
sort of very different architecture for a traditional web developer to
understand.

Thank you for help.

 Hi everybody,

 I am just new to GWT and experiencing a little bit with SmartGWT,
 implementing and trying to change the Tile Sort  Filtering Example
 from the Showcase 
 http://www.smartclient.com/smartgwt/showcase/#featured_tile_filtering

 I am trying to implement the above example with a fuzzy search but
 without the extra SearchItems, which causes the FuzzySearch to fail
 and draw back on an EQUALS search.


 Everything works fine with the example, but here comes my  'error' /
 'bug' :
 Here is an excerpt from the code from the showcase example:

 code

 final DynamicForm filterForm = new DynamicForm();
filterForm.setIsGroup(true);
filterForm.setGroupTitle(Search);
filterForm.setNumCols(6);
filterForm.setDataSource(AnimalXmlDS.getInstance());
filterForm.setAutoFocus(false);

TextItem commonNameItem = new TextItem(commonName);
SliderItem lifeSpanItem = new SliderItem(lifeSpan);
lifeSpanItem.setTitle(Max Life Span);
lifeSpanItem.setMinValue(1);
lifeSpanItem.setMaxValue(60);
lifeSpanItem.setDefaultValue(60);
lifeSpanItem.setHeight(50);
lifeSpanItem.setOperator(OperatorId.LESS_THAN);

SelectItem statusItem = new SelectItem(status);
statusItem.setOperator(OperatorId.EQUALS);
statusItem.setAllowEmptyValue(true);

filterForm.setFields(commonNameItem, lifeSpanItem,
 statusItem);

filterForm.addItemChangedHandler(new ItemChangedHandler() {
public void onItemChanged(ItemChangedEvent event) {
tileGrid.fetchData(filterForm.getValuesAsCriteria());
}
});

 /code


 Three search items are created and fit together in the filterForm.
 Using the form and entering just a part of a Common Name, will break
 down the results with each letter I type.

 Now comes the bad part:

 I do not want the lifeSpanItem and statusItem any more. So I change

 code
 filterForm.setFields(commonNameItem, lifeSpanItem, statusItem);
 /code

 to
 code
 filterForm.setFields(commonNameItem);
 /code

 Now, trying to enter just a part of a Common Name will not break down
 my results with each letter I type, but instead the behaviour is like
 commonNameItem.setOperator(OperatorId.EQUALS)


 So what I am saying is that the search works fine for searchItems
 greater than just one TextField. My workaround therefore was to create
 a HiddenItem as follows:
 code
 HiddenItem tagsItem = new HiddenItem(tags);
 tagsItem.setOperator(OperatorId.EQUALS);

 filterForm.setFields(commonNameItem, tagsItem);
 /code

 Now I think that this can't be right. Now am I missing something? Do I
 have to use .setOperator on commonNameItem, if only commonNameItem is
 present? If yes: Which OperatorId should I choose?


 Thank you very much for your help,

 Greets,

 Jan

Re: Offline GWT Applications

2009-08-18 Thread Dominic Holt


So it seems RPC calls definitely do NOT work when the browser is in
Offline Mode. If you just unplug your machine, RPC calls will still
work. If you, however, close the browser, and restart your
application, it is possible that your application will not load until
you've put the browser into Offline Mode. Once the application is
loaded, you can of course take it off this mode and the RPC calls will
work again. Does anyone know why I might have this problem where the
browser must be in Offline Mode to re-load the app? I assume it is
because I have built a Maps Application.

Use an Event Bus - Ray

2009-08-18 Thread Nathan


Hey GWT peoples,

  In Ray's GWT talk, he suggests using the Event Bus pattern in GWT
applications, to keep things clean.  Does anyone have suggestions on
how to approach this?  Do we think he meant use the EventBus available
at https://eventbus.dev.java.net/, or just the general Event Bus idea
with a custom implementation for each application, depending on its
needs?  Are there any people out there with a simple, GWT-oriented
(maybe even GWT-optimized) EventBus implementation that covers the
basics, and doesn't increase your GWT app size, that they are willing
to share?

This controller class is implemented using Struts2 (we're slowing
swapping out Struts in favor of GWT).  So, the service is wired up
using ServiceDefTarget to define the entry point in the Struts
controller.  Because of this setup, I can't run against the real
service in hosted mode (that I'm aware of).  So, we have a dummy
service implementation for that purpose and comment out the
ServiceDefTarget stuff.  From that point of view, everything seems to
be working.  It's just when I try to hit the real service that things
fail.  This works great for the first screen, but the new one is
failing.

Anyone got any insight that might help me track down the problem?
Thanks,
Dave

Code Splitting

2009-08-18 Thread lineman78


Is code splitting available yet in some sort of semi-finished form.  I
am about to start a rather large portlet project that is going to have
several main applications (known as components to those familiar with
Joomla) and would like to defer the loading of each of the components
until that area of the application is accessed.  I found some examples
of this for pre 1.4 with dynamic module loading, but I don't think
differed binding would work correctly for my application, as from what
I understand the code to decide the implementation class is only run
once and not every time gwt.create is run.  If code splitting is
available, could someone please provide an example of how I might
write my factory class.  Here is my first instinct of how it should be
used.

public final class ComponentFactory {
  public static Component getComponent(String pageArg, String[]
otherArgs)
  {
if (arg == null)
  return new BlogComponent(otherArgs);
  }
}

public final class ComponentWrapper extends Panel implements
HistoryListener {
  ...

  public void onHistoryChanged(HistoryEvent e)
  {
GWT.runAsync(){
  public void run()
  {
clear();
add(ComponentFactory.getComponent(HistoryManager.getPageArg(),
HistoryManager.getArgs()));
  }
};
  }
}

rich und web application in one Eclipse project

2009-08-18 Thread jenny


Hallo everyone,

i have a fine working eclipse-developed java rich client application.

Now i want a new way to display my data, namely in a browser.
(So i can install my app on a webserver)

But the existing solution has to work like it is!

I imported the GWT SDK 1.6.4. and the App Engine SDK 1.2.1 for getting
GWT components for the websolution.

But now my Swing components arn't supported any longer.

The question:
Is there a possibility to develop my new browser-solution with GWT
components alongside my rich client solution in the same eclipse
project?
Or do you know another solution for my prob?

Thanks for replys, jenny

Re: MVP design issue - any work around?

2009-08-18 Thread Dalla


Eventually, I solved it like you suggested.

I can see why this is good, as it will be decoupling the presenter
from the view.
However, it seems a bit bulky. Let´s say I want to be able to set a
style aswell,
add a KeyPressHandler, add a ValueChangeHandler and so on,
and that I have 10 or more textboxes in the same widget,
for example in a widget for user registration requering details about
address, phone number, email and so on.
I would probably end up with an interface with more than 50 methods...

Would this still be the way to go?

  Hi all

  A design question for everyone using MVP for their GWT
  implementations :-)

  I have a simple interface like so:

  interface ArrivalWidgetInterface {
             
             HasText getSlotText();
             
  }

  Let´s say that I want to set the SlotText in my widget implementing
  the above interface.
  I´m leaving some code out here, but it should be pretty straight
  forward if you have been using
  examples from Google IO 2009 and so on.

  Pretty simple, in a async success method I put the following:
  widget.getSlotText().setText(result.getSlot());

  Done.

  Let´s say now that I want to manipulate the Slot textbox in some other
  way,
  for example disable it after the value has been set.
  How can I do this in a good way?

  Changing the interface to return an TextBox instead of the HasText
  interface seems like a bad idea,
  since that would give me problems when testing. If possible you´ll
  want to keep all the UI-code outside the presenter, right? So what
  would be best here? Create a new public method in the widget, and
  expose that method in the interface aswell?

Re: MVP design issue - any work around?

2009-08-18 Thread Daniel Jue


You have to decide on the granularity you want.  I found it easier to
use an interface that would give me the actual widget in my presenter,
and then the presenter can do several things on each widget as it
needs.

I am using the widget's class in the interface, since I am using
SmartGWT widgets it seemed easier that way.  I kept switching back and
forth between different widgets that had different Has Click
Handlers types of interfaces. (the kind for Forms and the regular
kind)

So I may only pass back 4-5 widgets for a simple login widget.  Also
one of the widgets I modify through a setter in the view, which is
also defined in the interface given to the presenter.  One setter in a
view of my app is a SetStatusText(String text), so the presenter can
update as it the RPC is going on.  I'm still trying to find a
consistent approach that is easiest to manage.

Re: MVP design issue - any work around?

2009-08-18 Thread Ian Bambury

Probably not.
I'm no expert on this, but my intuition would say that if you want to have,
say, a telephone number entered then your registration view ought to add a
TelephoneNumber widget which would have the logic in it to validate
telephone numbers. You would then only need logic in the registration
presenter/controller to say thiungs like

if(phone.isValid())...

or

if(!phone.isEntered() || phone.isValid())...

or

if(!phone.isValid(country.getCountryCode())) phone.indicateInvalid()...

depending how complicated you want to get, and somewhere else

phone.getPhoneNumber()

if everything is OK

the registration presenter/controller can easily formulate the business
logic required for optional and required fields. It would be a lot simpler
than just having a whole load of text fields that the registration
presenter/controller had to validate everything in every way.

But I haven't really thought it through :-)

I have a question similar to this one? Has the GWT team ever
considered adding a CSS compiler into GWT? Example create classes
and such in Java that help with the layout. Offering as much
flexibility as possible as CSS does, but then making the CSS browser
independant as well as the JS. In this way the CSS can be compiled
with the rest of the page, but we can be sure that (to the best of
googles ability) our pages will look identical regardless of browser.

has this been discussed/considered?

Using horizontal and vertical panels is the prefered way of realizing

For my layouts I use tables, meaning gwt horizontal and vertical panel,

Hi,

I'm trying to use CSS for the layout of my website (for now, the

Does GWT developpers really use CSS? For what use? (IMHO positionning
with CSS really suck, the margin: auto to center a div doesn't work
on IE8)

Re: Which use for CSS?

2009-08-18 Thread brian richards

HI Guys,

I am new to Java and everyday i am seing the discussions and i have a small
doubt that please give me the simple View about GWT and let me know the full
form of GWT.

 I have a question similar to this one?  Has the GWT team ever
 considered adding a CSS compiler into GWT?  Example create classes
 and such in Java that help with the layout.  Offering as much
 flexibility as possible as CSS does, but then making the CSS browser
 independant as well as the JS.  In this way the CSS can be compiled
 with the rest of the page, but we can be sure that (to the best of
 googles ability) our pages will look identical regardless of browser.

 has this been discussed/considered?

   It seems like the themes used in GWT only change colors, which is not

GWT.create() doesn't work outside onModuleLoad()

2009-08-18 Thread Adam Pratt


Hey All,

I'm trying to get one very simple line of code to work:

MyService service = GWT.create(MyService.class);

I've been playing around with this a lot, and I'm noticing that this
works fine within in the onModuleLoad() method, but anywhere else in
my client code, I get the following error (when in hosted mode):

java.lang.ClassCastException: [packagename].shared.MyService_Proxy
cannot be cast to [packagename].aspect.shared.MyService

Anyone know what might be causing this error?

Thanks,
Adam

NullPointerException when annotations are used


I just added google-gin to my project.  I set it up and configured it

doing DI just fine -- as expected.

However, now when I try to compile, I get this stack trace:

[other stuff deleted]

gin-1.0-SNAPSHOT.jar I built today from SVN revision 109 of google-
gin.  The annotation class for @GinModules does exist in the jar at
com.google.gwt.inject.client.GinModules

I'm at a loss for why this is failing.  Can someone help?

Thanks!

Re: GWT.create() doesn't work outside onModuleLoad()

2009-08-18 Thread Adam Pratt


The problem I was having with MyServiceAsync is that if I want to call
service.getSomething(), I had to pass in an AsyncCallBack object with
two functions: onSuccess() and onFailure(), both of which are of type
void. I can't, within onSuccess(), set a global string variable to a
certain value, which is what I'm trying to do (if you don't understand
what I mean, check out 
http://www.java-forums.org/new-java/20629-callbacks.html).

Also, if I'm able to use GWT.create() to create a MyService object in
onModuleLoad(), why am I unable to do this elsewhere?

Re: NullPointerException when annotations are used


Thank god for online source.  line 704 of TypeOracleMediator:

http://code.google.com/p/google-web-toolkit/source/browse/releases/1.7/dev/core/src/com/google/gwt/dev/javac/TypeOracleMediator.java

if (expectedElementValueType.isArrayType()  -- NPE

the object is passed into the method from above (line 441-442):

TypeBinding expectedElementValueType = mvp.binding.returnType;
Object elementValue = getAnnotationElementValue(logger,
expectedElementValueType, expressionValue);

It seems mvp.binding.returnType returns null -- anyone familiar with
GWT code know what might be the root cause?

right, you need to read:
http://groups.google.com/group/Google-Web-Toolkit/browse_thread/thread/faca1575f306ba0f/3be719c021aa19bd

Now, what you'd get as a return from you method is not at all what you  
would expect.

myVariable will NEVER be set by the time you exit the method.

Re: MVP design issue - any work around?


I asked pretty much the same question:
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/19b1600e34ca8f99#

I am in the same boat as you are.  I am trending toward just returning
a TextBox when it is really a TextBox I have in the view.  Will I
really need to change the TextBox with something else?  Sure maybe I
might add some other widget library's TextBox, but this is not really
a future concern, and regardless, re-factoring something like this in
an IDE by changing the interface is a 5-second operation.  It isn't
like this interface is widely used by the rest of the code base --
we're talking about coupling two classes here.

You can mock TextBox with EasyMock.createMock(TextBox.class), so
testing isn't a problem.

Regards,
Davis

 Eventually, I solved it like you suggested.

 I can see why this is good, as it will be decoupling the presenter
 from the view.
 However, it seems a bit bulky. Let´s say I want to be able to set a
 style aswell,
 add a KeyPressHandler, add a ValueChangeHandler and so on,
 and that I have 10 or more textboxes in the same widget,
 for example in a widget for user registration requering details about
 address, phone number, email and so on.
 I would probably end up with an interface with more than 50 methods...

 Would this still be the way to go?

 On 18 Aug, 14:10, Ian Bambury ianbamb...@gmail.com wrote:

  How about
  void setEnabled(boolean enabled);
  It's really up to the view how it indicates whether something is disabled or
  not. Different views for the same interface might do different things.

   Hi all

   A design question for everyone using MVP for their GWT
   implementations :-)

   I have a simple interface like so:

   interface ArrivalWidgetInterface {
              
              HasText getSlotText();
              
   }

   Let´s say that I want to set the SlotText in my widget implementing
   the above interface.
   I´m leaving some code out here, but it should be pretty straight
   forward if you have been using
   examples from Google IO 2009 and so on.

   Pretty simple, in a async success method I put the following:
   widget.getSlotText().setText(result.getSlot());

   Done.

   Let´s say now that I want to manipulate the Slot textbox in some other
   way,
   for example disable it after the value has been set.
   How can I do this in a good way?

   Changing the interface to return an TextBox instead of the HasText
   interface seems like a bad idea,
   since that would give me problems when testing. If possible you´ll
   want to keep all the UI-code outside the presenter, right? So what
   would be best here? Create a new public method in the widget, and
   expose that method in the interface aswell?

 Right, but why not just do:

Great! That's the track that I'm on. Thanks for the confirmation.

 If all goes well, your provider will be inlined so having two classes
 won't have any runtime overhead.
 
 Are there any examples that use Gin and JSNI?
 
 I'm not sure I understand what problem you have and/or want to solve.

The specific problem is that I want to be able to re-purpose the
PagingScrollTable sample using a JSON data source.

Right now, I'm working on the tri-state data generator in that sample:
generate zero rows; generate data from the server; generate random data.
I'm sure that particular routine is a perfect fit for Provider.

Right now I'm trying to get the random data generator part to work.

Re: Use an Event Bus - Ray

Request: programmatically setting the style com.google.gwt.dom.client.Element.getStyle()

2009-08-18 Thread GWTCurious


There exist the method com.google.gwt.dom.client.Element.getStyle() to
get the Style object of the element but there is no corresponding
setStyle() method. Also Style has the getProperty() and setProperty()
methods but no removeProperty method().

Consider the case : you want to add width and height properties to an
image to programmatically zoom it but later want to reset it to  the
original style. Currently you can not remove the width and height
properties, you could only set their values to original size values.
But this has not the same effect as resetting the style to the
original status without with and height properties. For example if you
would like the animate the image, size and width properties cause
animation to be not fluid.

So either we should have com.google.gwt.dom.client.Element.setStyle
(Style s) to set back the original saved style object or Style should
have a removeStyle(String property) method to remove a property from a
style. Best we should have both as it gives flexibility regarding
dynamic styling.

What do you  think?

Re: Who is using smartgwt?

2009-08-18 Thread shay


a few other aspects that i was considering before going with smart.

1) documentation on smart is much better, which is a major issue.
2) dev console is a huge help.
3) although isomorphic on the forums is at times raw , Ext have
their own raw posters which when combined with the lack of
documentation is a serious issue.
4) i found the ext architecture to be overly complex, for example
their data binding , maybe sometimes you need all this complexity ,
but sometimes you don't , Smart components allow me to start simple
and add complexity later, Ext forces me into the complexity from day
one.
5) I might be wrong , but Ext feels to me just like Spring, their open
source code is just a way to drive , sales of books, trade shows , and
support contracts.  Now don't get me wrong they should be able to make
money , but i i find their approach a bit forced. not to mention the
fact that there are as good alternatives like smart that don't suffer
from these shortcomings.

I'm creating a project for the plugin + guice gin + gwt validation. It

Drawing graphics without using Canvas

2009-08-18 Thread David Given


-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

I've got an app which is going to want to draw some simple diagrams
client-side. I don't want to use a Canvas for this, partly for
compatibility reasons, and partly because the hosted browser doesn't
support it which makes it a pig to test.

Right now I'm using DOM to create a DIV containing lots of other DIVs
- --- all I need is text and horizontal and vertical lines, so this works
fine, but it's a bit slow. Right now I have about 500 graphics elements
and I'm probably going to want to double that eventually.

What other choices do I have?

(What I'd *particularly* like is a nice GWT wrapper widget which
abstracts over all the implementation details and uses Canvas, VML or if
all else fails, this:

http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm

...but I haven't found one yet.)

 I'm not sure I understand what problem you have and/or want to solve.

I think I have a solution. As I understand it, when testing, one
modifies the Gin Appmodule as required?

In this example, I use the EmptyServer... provider. When in
production, I use the Server... provider.

The class retrieved as the Provider is never used; the JSNI class is
read/written directly. The Gin magic still happens. I can prove this by
referencing ServerProvider (which doesn't yet initialize the Server
class). Sure enough, the setId() method fails at runtime with a no
properties exception.

o The JavaScript overlay type Server is as expected, i.e. as described
at
http://code.google.com/webtoolkit/doc/1.6/DevGuideCodingBasics.html#DevGuideOverlayTypes

o The Gin AppModule is basically:
package com.foo.client.jsnitest.client;
import com.google.gwt.inject.client.AbstractGinModule;
public class AppModule extends AbstractGinModule {
 @Override
 protected void configure() {
  bind(Server.class).toProvider(EmptyServerProvider.class); // test
or
  bind(Server.class).toProvider(ServerProvider.class); // production
 }
}

o EmptyServerProvider is basically:
package com.foo.client.jsnitest.client;
import com.google.inject.Inject;
import com.google.inject.Provider;
public class EmptyServerProvider implements ProviderServer {
 private final Server   server;

 @Inject
 public EmptyServerProvider() {
  this.server = getEmptyServer();
 }

 @Override
 public Server get() {
  return server;
 }

 public final native Server getEmptyServer() /*-{
  var JSONObject = '{server : {id : '}';
  return eval('('+JSONObject+')');
 }-*/;
}

o A Server consumer is basically:
package com.foo.client.jsnitest.client;
import com.google.inject.Inject;

public class MainWidget {

 private final Server server;

 @Inject
 public MainWidget(Server server) {
  this.server = server;
  GWT.log(1. Server: +server.toSource(),null);
  server.setId(001);
  GWT.log(2. Server: +server.toSource(),null);
}

Re: MVP question

2009-08-18 Thread Davis Ford


Hi Thomas, thanks for replying...

The style thing is I guess questionable, but the basic problem with
the pattern as presented which favors the Has* interfaces, etc. I
think is still a design issue to consider.  Another post shortly after
mine basically issued the same question
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/19b1600e34ca8f99/b6671eb90041154c#b6671eb90041154c

If it isn't addStyle( ) (your point is well taken)...it will be
something else the presenter wants to manipulate on the view's widget.

I guess my point is that if you have a view that is something beyond
most blog/tutorial posts, it just seems to me that not returning the
actual widget either makes the interface blow up, or you end up doing
lots of nasty casting.

My basic question is: why not just return TextBox if that is what is
in your view?  The coupling is between 2 classes: view and presenter.
If you later change TextBox to SuperWidgetTextBox, you can re-factor
it in your IDE in 5 seconds and be done with it.

Am I missing something?

Regards,
Davis

 I'm trying to implement a version of MVP as discussed at Google I/O
 talk:

 http://code.google.com/events/io/sessions/GoogleWebToolkitBestPractic...

 So, one can have a presenter class that defines an internal interface,
 and I see it typically done like this:

 class PhoneEditor {
    interface Display {
       HasClickHandlers getSaveButton();
       ...
    }

 It seems to me that this tends to get a bit unwieldly in practice.
 For example, I have an account registration page.  Let's say it
 contains a TextBox for username and a PasswordTextBox for password.

 Here are some things I'd like to do to that box in my presenter:

 get the value, so I could have

   interface Display {
      HasValueString getUsername();
      HasValueString getPassword();
   }

 But I also have validation code in my presenter, which will validate
 the content of the fields, and do things like set style errors.

 #addStyleName( ) is defined on UIObject, so I'm kinda out of luck with
 that interface unless I define something like:

     interface Display {
      HasValueString getUsername();
      HasValueString getPassword();
      UIObject getUsernameBox();
      UIObject getPasswordBox();
   }

 but that is kind of a ridiculous and redundant interface.  So, really,
 my question is what is so wrong with:

     interface Display {
       TextBoxBase getUsernameBox();
       TextBoxBase getPasswordBox();
     }

 I get the fact that if you can use the Has* interfaces, it helps
 decouple the presenter from the view more by allowing the view to
 change to other UI widgets later on, but I find it far too limiting in
 being able to manipulate the view objects without either having large,
 redundant interfaces or else doing lots of unsafe casting.

 Has anyone else encountered this conundrum, and how are they
 approaching it?  I'm inclined to make my Display interfaces explicit.

 Your presenter shouldn't deal with styles, it should instead tell
 the view to show error near/on the username and/or password (or
 nowhere particularly). It's the responsibility of the view to
 determine (be implemented that way) if it should set a red background
 and/or red border on the textbox, and/or show an icon next to the box,
 and/or show an error summary above or below the boxes, etc.
