Re: Classloader problem

hi, when you put something into WEB-INF/lib folder, the library is
loaded to the classpath of the servlet container regardless if its on
eclipse classpath or not. if you dont want to roll out the library
with the war file or it resides somewhere else than WEB-INF/lib - you
can still add the jar to eclipse classpath manually, so just do it.

you can also put this special jar on servlet container's classpath
when starting it, do it from a context menu on the root project -
Run... - Run As... then ensure Google Web Toolkit is selected on
the right menu and choose the Classpath tab on the right window
panel, then add the jar there manually and click Run

Re: Script tag dynamic loading

..but watch out, in case you have a code depending on A.js you cannot
run it directly after loadJS(A.js) - it will not work, since
loadJS() is always asynchronously loaded, meaning you code is executed
whilst A.js has not been loaded yet, you have to work with callbacks
to proceed executing AFTER A.js has been loaded

this is a little bit tricky, since SCRIPT tag does not allow you cross-
browser to hook in to know if code is loaded, but there some
strategies for it we can discuss if your problem really relates to the
async control flow..

Re: synchronize asynchronous calls?

write a class which can be used like this:

Executor.async(cmd1).async(cmd2).async(cmd3).sync(cmd4)

it gonna start cmd1..cmd3 and when all are finished it gonna start
cmd4
and go for observer pattern

everytime an async call finishes it checks if it was the last one, if
so it triggers cmd4,
being in java you could have implemnted the lock with .wait()
and .notify() but in javascript its not possible where yu have to
write an own blocker, which imitates the wait() on java side, for this
you can use a timeout with maximum waiting time looping forever, so
the browser prevents execution, your executor should then implement
clearTimeout() which is called upon every async call termination
causing the timer to terminate and iterating with the next operation

On 12 Aug., 16:30, Kevin Qiu kevin.jing@gmail.com wrote:
 I don't know if the title makes sense but working with gwt for about 2
 years, I often find myself in the position to mix both asynchronous and
 synchronous (blocking) apis. It's easy to transform a synchronous call to
 asynchronous, but the other way around is not immediately obvious to me,
 especially in the context of the single-threaded browser environment.

 Imagine I the following:

 abstract class GetListT {
   abstract void execute(AsyncCallbackListT callback);

 }

 class GetContactList extends GetListContact {
   void execute(AsyncCallbackListContact callback) { /* implementation */

 }
 }

 class GetAddressList extends GetListAddress {
   void execute(AsyncCallbackListAddress callback) { /* implementation */

 }
 }

 class GetPhoneList extends GetListPhone {
   void execute(AsyncCallbackListPhone callback) { /* implementation */ }

 }

 now imagine I keep a list of GetList objects:
 ListGetList commands = Arrays.asList(new GetContactList(), new
 GetAddressList(), new GetPhoneList());

 and I have an executor that executes these commands:

 class Executor {
   List? extends GetList? commands;
   Executor(List? extends GetList? commands) {
     this.commands = commands;
   }
   void execute() {
   // XXX:
   }

 }

 Now, for whatever reason, I need my execute() method to be a blocking call
 (synchronous). It should terminate after all GetList calls are returned. How
 can I achieve this?

Re: String.matches() does not work with \p{ASCII}

hard to say, its up to the engine implementing regex, if you want to
check for ascii code of each character you gonnamake a loop

like

function isAscii(str){
for(i=0;istr.length;i++){
 if(str[i]127)return false;
}
return true;
}

when making regex its like a touring machine which scans the character
applied to the pattern, so it also depends on a pattern how many chars
are scanned, and in your case you want to know if a character is in
ascii range, so anyway it has to scan each. there is one chance regex
is faster inthis case, if its implemented natively and not
interpreted.

the loop above has the advantage is has not to scan all of the chars,
in case its not ascii but returns after first non-ascii

  faster than a regex evaluation

 Are you sure? given that trimming blanks is faster with regexes
 (str.replace(/^\s+/, ).replace(/\s+$/, )), I tend to think that
 regexes are really fast.

Yes, yes and YES ! ;) The lack of pure GWT widgets really does hurt, I

MyWebApp is not a GWT project - message

Hi,

How do I launch a project in debug mode in Eclipse that was created
with the command line tool?

- - - Background - - - -

Following the tutorial, I created an application using the command
line:

webAppCreator -out MyWebApp com.mycompany.mywebapp.MyWebApp

Next, I installed the Eclipse plug in.  I imported the MyWebApp
project into eclipse.

When I click Projects - Run As, I do not see an option for Web
Application as the tutorial says I should.  When I try to compile the
GWT project, I get the message, MyWebApp is not a GWT project.

When I try to create a debug configuration, the message appears
Project does not use GWT or GAE.

The gwt-user.jar and gwt-dev.jar of GWT 2.0.4 are both referenced
libraries.

What am I missing?

You might want to use a Label (or maybe Anchor if you want it to

copy link URL, etc.) with a ClickHandler in which you'd call
History.newItem *and* do what you want to do (or: call newItem(token,
false) and then fireCurrentHistoryState if you really want to keep
your logic ValueChangeHandlers)

Using UI Binder

2010-08-13 Thread $ a r j i t h Pullithodi

HI All,


   I am a beginner in GWT, I was trying to develop an application through UI
Binder way. but it found really difficult to integrate designers (html) code
to gwt widgets. is it possible to use g:widgets inside html tag and vice
versa?. I can't use complete html as ui binder xml since its owner class
will be an UIObjects instance instead of a widget instance.

Any suggessions?? or any site for reference ??

Re: showing all the elements from SuggestOracle in suggestionBox

2010-08-13 Thread ctasada

You can send me a private message attaching the source of your class,
so I can take a look.

I'm using it in my code without problems.

 Hello,

 yes you are right we dont have direct access to SuggestBox Popups.

 I have already extended SuggestOracle and have overridden method

 requestSuggestion(request,callback);

 code for the following as follows :

 public class StartsWithSuggestOracle extends SuggestOracle
 {
    //...  some other code...

 *   �...@override*
 *    public void requestSuggestions(Request request, Callback callback) *
 *    { *
 *        final List suggestions =
 computeItemsFor(request.getQuery().toLowerCase(),request.getLimit()); *
 *        Response response = new Response(suggestions); *
 *        callback.onSuggestionsReady(request, response); *
 *    } *

 }

 and the underlined method computeItemsFor(); returns me the suggestions
 based upon request so as per my

 logic if request contains no character that is an empty string  i have
 returned all suggestions from oracle object.

 so here i m able to get this response correctly but i m nt getting wht
 should be done next with this response.

 from where i should give a call to this method and how that list get
 populated.

 I have followed that link suggested by you but that was the same mechanism
 that used there.

 so i m lil confuse why its not showing the response.

  Hi Aditya,

  The problem is that you don't have direct access to the SuggestBox

  If you want to see all the possible solutions you should extend the
  SuggestOracle and implement your own requestSuggestions method (see

  In this way yo can simply return all your list, even ignoring the

Re: MyWebApp is not a GWT project - message

You need to go to the Project Properties (right-click on your project),
under Google, Web Toolkit Settings, and click the button that says Use
Google Web Toolkit (same for AppEngine, if you're using it). Also, make
sure that under Web Application, the button that says This project has a

Re: CalendarService application showing total meeting from Google Calendar

2010-08-13 Thread ichi

Fernando, I've already downloaded the right version, but I've already
checked each class in which the compiler said the method is undefined,
such as:
getEventEntries (in Calendar Service
http://code.google.com/intl/fr/apis/gdata/javadoc/com/google/gdata/client/calendar/CalendarService.html
I also didnt find getEventEntries()),
show data( in CalendarEventEntry), etc

But the code that i copied is exatcly from the Book of Programming
GWT, so i think it should work.
And this method of getEventEntries I found in JavaScrip doc, I'm
confused, may be you can suggest?

otherwise --no noServer-- it doesn't really work when multiple modules
are used either, looking for a module name in the runTarget). Some

Re: synchronize asynchronous calls?

2010-08-13 Thread Kevin Qiu

Jeff,

is it safe to say the skeleton of your method looks like this?

void execute() {
  // 1
  DeferredCommand.addCommand(new IncrementalCommand() { /* state machine
logic as posted above */ }
  // 2
}

The problem is, DeferredCommand isn't blocking, so after
DeferredCommand.addCommand(...), whatever logic you put inside the
incremental command won't be executed before the outer execute method
finishes. e.g., if I put System.out.println(execute() started) at //1
position and println(execute() finished) at //2 and loads of print()
inside the incremental command, the output will be:
  execute() started
  execute() finished
  // whatever I put in the incremental command
Therefore, execute() method isn't blocking.

I think I need to clarify/reiterate what I need: I have a list of async
commands, and I want execute() method to execute these commands, either in
serial or parallel, and execute() method waits until all these commands
finish and then returns.

 It's a processing occurring timer. I think I mentioned it earlier, so
 I didn't remove it from the example.

  (IncrementalCommand is executed by DeferredCommand.CommandExecutor
  and it already has a timer with timeslice set to 100ms).

 Right.

  Also, I suppose you need to reset the busy flag in the callback of
  the asynchronous calls.

 Yes. You already had that bit sussed. The case statement asynchronously
 drains the command queue, while providing a structure that synchronously
 resolves to a final command step.

  I'm still a bit incredulous but I'll give it a try. Thanks again :)

 Feel free to ask.

  Looking at your code a bit more closely (and while composing an

  structure.
 
  You have the IncrementalCommand() correctly implemented. Forget my
  previous answer.
 
  Now that I really understand what you're asking (I think)...
 
  I solve the problem using a state machine. Notice how the SM loops on
  DICTIONARYREAD until the command queue is empty.
 
  DeferredCommand.addCommand(new IncrementalCommand() {
   @Override
   public boolean execute() {
 switch (startupState) {
   case INITIAL:

 startupState = StartupState.DICTIONARYREAD;

 startupState = StartupState.FINAL;
 break;
 
   case FINAL:  // Kevin's RETURN POINT?
 timer.cancel();
 return false; // command is complete
   }
 return true;
  });
 
  public boolean getDictionaryPages() {
   while (dictionaryRequestList.size()  0) {

Re: synchronize asynchronous calls?

2010-08-13 Thread Kevin Qiu

cokol,

could you elaborate on the timer idea? namely, how do you block the current
executing method using a timer?

I'm sure I missed your point, but just for argument's sake, I cooked up this
method:
public void execute() {
  Timer blocker = new Timer() {
public void run() {
  while (currentIdx  commands.size());  // 1
  this.cancel()  // 2
}
  }

  DeferredCommand.addCommand(new IncrementalCommand() { /* checking if it's
busy, if not, get the next cmd and execute. increment currentIdx, etc etc */
});

  blocker.scheduleRepeat(100);  // 3
}

Now // 3 is supposed to help me block execute() method from returning,
except that // 1, the spinning lock locks the current thread, and // 2 is
never going to be called, because the incremental command never gets a
chance to execute, so currentIdx is going to stay the same.

I'm sure I'm doing it the wrong way, but I haven't figured out how a timer
can help me here. Maybe you can enlighten me.

 write a class which can be used like this:

 Executor.async(cmd1).async(cmd2).async(cmd3).sync(cmd4)

 it gonna start cmd1..cmd3 and when all are finished it gonna start
 cmd4
 and go for observer pattern

 everytime an async call finishes it checks if it was the last one, if
 so it triggers cmd4,
 being in java you could have implemnted the lock with .wait()
 and .notify() but in javascript its not possible where yu have to
 write an own blocker, which imitates the wait() on java side, for this
 you can use a timeout with maximum waiting time looping forever, so
 the browser prevents execution, your executor should then implement
 clearTimeout() which is called upon every async call termination
 causing the timer to terminate and iterating with the next operation

  I don't know if the title makes sense but working with gwt for about 2
  years, I often find myself in the position to mix both asynchronous and
  synchronous (blocking) apis. It's easy to transform a synchronous call to
  asynchronous, but the other way around is not immediately obvious to me,
  especially in the context of the single-threaded browser environment.
 
  Imagine I the following:
 
  abstract class GetListT {
abstract void execute(AsyncCallbackListT callback);
 
  }
 
  class GetContactList extends GetListContact {
void execute(AsyncCallbackListContact callback) { /* implementation

  }
  }
 
  class GetPhoneList extends GetListPhone {
void execute(AsyncCallbackListPhone callback) { /* implementation
 */ }
 
  }
 
  now imagine I keep a list of GetList objects:
  ListGetList commands = Arrays.asList(new GetContactList(), new
  GetAddressList(), new GetPhoneList());
 
  and I have an executor that executes these commands:
 
  class Executor {
List? extends GetList? commands;
Executor(List? extends GetList? commands) {
  this.commands = commands;
}
void execute() {
// XXX:
}
 
  }
 
  Now, for whatever reason, I need my execute() method to be a blocking
 call
  (synchronous). It should terminate after all GetList calls are returned.
 How
  can I achieve this?

 Jeff,

 is it safe to say the skeleton of your method looks like this?

 void execute() {
   // 1
   DeferredCommand.addCommand(new IncrementalCommand() { /* state machine
 logic as posted above */ }
   // 2
 }

 The problem is, DeferredCommand isn't blocking, so after
 DeferredCommand.addCommand(...), whatever logic you put inside the
 incremental command won't be executed before the outer execute method
 finishes. e.g., if I put System.out.println(execute() started) at //1
 position and println(execute() finished) at //2 and loads of print()
 inside the incremental command, the output will be:
   execute() started
   execute() finished
   // whatever I put in the incremental command
 Therefore, execute() method isn't blocking.


Of course the DeferredCommand isn't blocking. I know that. The SM just loops
at DICTIONARYREAD until the queue empties. Post your entire implementation
of the execute() method.

Do not put code at //1 or //2 Did my example show that? I don't think it
did. //1 and //2 should be inside the SM. Did you code an implementation or
just do a desk check?

The dictionary entries are downloaded one at a time. The UI isn't live until
all downloads complete. Either way, it looks like I've failed to communicate
how this works. If you want to see a live demo, feel free to send an OpenID,
I'll add it to to the authorization and you can watch it using FF and
Firebug.



 I think I need to clarify/reiterate what I need: I have a list of async
 commands, and I want execute() method to execute these commands, either in
 serial or parallel, and execute() method waits until all these commands
 finish and then returns.

It does. As I noted earlier, the position of those code fragments won't

logic. Placing them where you did simply {ignores | doesn't follow} my
advice.

To correct your example:
code fragment //1 goes in the body of INITIAL state. This message will
print once.

code fragment //2 goes in the body of the DICTIONARYREAD state. This
message will print for each element in the execute queue.

code fragment //3 (not shown) goes in the body of the FINAL state.

Re: GWT/Tomcat serialization issues during deployment

2010-08-13 Thread duey

Had to get my hands dirty to figure this one out.  Here's how I got
around these exceptions.

1. First, on the client side.  Instead of calling
testService.sendTestData(new TestData(), sendTestDataCallback);   I
did the following:
String content = ServiceUtils.marshallTestServiceObject(new
TestData());
testService.sendTestData(content, sendTestDataCallback);

where marshallTestService looks like this:
public static String marshallTestServiceObject(Object obj) {
String content = null;
SerializationStreamFactory factory = 
GWT.create(TestService.class);
SerializationStreamWriter writer = factory.createStreamWriter();
try {
writer.writeObject(obj);
content = writer.toString();
} catch (SerializationException se) {
content = null;
}
return content;
}

That successfully sent the object to the server side.

2.  On the server side I had to create my own
AbstractSerializationStreamReader and call it as follows:
 CustomSerializationStreamReader reader = new
CustomSerializationStreamReader(
Thread.currentThread().getContextClassLoader(), 
null);
try {
reader.prepareToRead(content);
TestData testData = (TestData)reader.readObject();
// viola, I have the testData instance
} catch (SerializationException se) {
se.printStackTrace();
}

Before I created a custom string reader I tried to use the
ServerSerializableStreamReader.  This did not work because of the
following line of code:
Constructor? constructor =
instanceClass.getDeclaredConstructor();

That line of code essentially makes the following call:
 
System.getSecurityManager() 
.checkMemberAccess(TestData.class.getDeclaredConstructor().getClass(),
Member.DECLARED);

Unfortunately, when Tomcat is running with a security manager,
this call causes an AccessControlException because we can only see
Member.PUBLIC.  So...Long story short.  My
CustomSerializableStreamReader simply calls Constructor.newInstance(),
which does the trick.  I know that my default ctor exists and is
public so this worked for me.

I hope somebody is able to find this useful.  Especially if you run
your app on GoDaddy and need reflection.

Acris Security and App Engine

2010-08-13 Thread spierce7

I've been trying to find out more information about sessions in GWT,
as I couldn't figure out how to get them to work, and something that I
stumbled across is Acris, which has a Security implementation. I've
been reading about it and I can't find detailed information on how to
use maven to setup a gwt project, and I'm so confused as to how maven
works, or what it's actual purpose is even. However, Acris is
something I'm very interested in using.

I was searching around trying to figure out how I could do this, and I
happened across a post of someone telling someone that acris couldn't
be implemented onto projects hosted with AppEngine. Is this true?

Also, does anyone have some detailed steps as to how I setup Maven
with GWT and Eclipse? I've installed maven on eclipse, but now (from
what I gather, I'm taking a leap and concluding this) I have to do
some setup in my pom.xml file. I don't know if this is before or after
the creation of the project, but I can't figure out how to create a
project either, so overall I'm very confused. I'd be thankful for any
help at all in this area.

The host html alignment always overriding the the alignment of the horizontal panel

Hi,

The following is part of my host file.
table align=center
tr
td id=main/td
/tr
/table

HorizontalPanel hpanel = new HorizontalPanel();
hpanel.add(button);
hpanel.setHorizontalAlignment(ALIGN_CENTER);
Root.get(main).add(hpanel); 

The alignment is always dominating by the setting of the html host file; So 
from above, the button in hpanel is aligning on the left instead of the center. 
How can I make the setHorizontalAlignment effective again?

Thanks

Thanks, but it's not the panel I want to decorate, it's the elements
within the panel (i.e. I want to put a box around Center).

Yes, I know, use uibinder.  That doesn't work when you're building
things grammatically, which is what I'm doing.

BTW, why don't the Showcase application use ANY *LayoutPanels?  I
thought they were supposed to be the preferred way to do things, no?

Expose URL as REST service how?

Hi All,
I am evaluating GWT for my new project which is going to be started
shortly. I have a requirement with REST support.

For example, I have a list of users. If I click on any one the user,
the details of the user will be shown in a different view.

I need to expose this URL, http://sample.com/user/123 as a REST
service.

If anyone try to access this URL directly, the particular user details
should be shown.

I don't know how to achieve this using GWT. I am using RPC service to
fetch the details of the user from the server.

Can any one help me on this?

How to send data back to client side code?

StringArray to client/Example.java am fine, but now I tried to send

Question about GwtEvent and setting source

2010-08-13 Thread Christian Goudreau

I wanted to set the source of my custom event fired on our eventBus and
ended up digging inside handlerManager just to find out that we just can't
set the source. Source is package private AND setted uppon creation of
HandlerManger.

Common pratice for an EventBus is to extends HandlerManager... and set the
source to null.

Is there a good reason why we can't have a setSource function iside GwtEvent
?

Thanks

Re: Expose URL as REST service how?

REST is provided by most app servers in the form of a reference
implementation of JSR-311.  Glassfish uses Jersey, JBoss RESTEasy.
Most app servers bundle support in one way or another now.  Some GWT
people have found RESTlet easy to use also.  The Jersey users manual

It's a bit complicated (otherwise you would have to overwrite the

@TimeoutCapable(15000)

That should work for most cases (unless you want different timeouts

question about code splitting

2010-08-13 Thread Joe Hudson

Hi,

I'm wondering if I still get the benefits from code splitting from the
example below:

String className = MyClass.getName();
...
GWT.runAsync(new RunAsyncCallback() {
  onSuccess() {
new MyClass();
  }

  onFailuare() {
 ...
  }
});

Basically, I am wondering that since I referenced MyClass.getName()
prior to the GWT.runAsync, does that kill the benefits I would get
from code splitting if I am trying to load all of the code related to
MyClass asynchronously.  Thanks.

UiBinder Performance

2010-08-13 Thread Adam

I have been looking over the ColumnDefinition code from
http://code.google.com/webtoolkit/articles/mvp-architecture-2.html
MVP Architecture 2.  In particular the render method.  We have
considered using UiBinder in the render portions.  The concern some of
us have are the performance implications.  Consider an example where
we generate a table with 10 columns and 100 rows.  Just like in the
architecture each row is a model object.  The though is instead of
using inner html to render (probably the fastest way) we're
considering using a UiBinder.ui.xml view instantiated multiple times
(once per row). So based on my example above we'd have 100 model
objects, and UiBinder fragmets. The reason we've considered this
method is to remove html code generation in Java.

I was wondering what everyone thought about this or if they have
another idea?

Re: How to send data back to client side code?

hi the problem is that gwt does not have source of your Employee
class, since you have put it into the server package, you always have
3 packages to handle (as per default):

client
server
shared

everything under client becomes javascript after compilation and is
not aware of anything contained in server package, everything
contained in server package is intended to run in java VM and remains
java, here you may have references to classes used in client package
if you like, this would not break up gwt. the shared package contains
everything what is required for client and server package, like the
service interfaces AND transfer objects  payload classes like your
Employee. furthermore everything whats inside client and shared
package has to be translatable to javascript, i.e. you shall not use
3rd party libraries in there.

so just move the Employee and all related (payload) classes to the
shared (or client) package and you are done

Re: question about code splitting

to load code asynchronously does not make sence unless not loaded by
demand, as a sample:

if you have login-screen as a first screen, and after login you want
to initialize the application,here you would benefit from splitting
the code, one part to handle login and the other for entire
application, because you never need entire application code as long as
you have not logged in successfully

  if(s.matches(\\p{ASCII}*))

  else

MVP suggestion

2010-08-13 Thread dmen

Hi, consider a panel that starts by showing a couple of buttons. When
you press a certain button, the panel expands with a form and an
anchor link. When you click the link, the panel expands once again
with some html content. The actual business purpose of the panel is
the form.

Everything is coded within the component and works fine. Now I'd like
to experiment with the View/Presenter pattern and move behavior from
the panel (view) to the presenter.

My questions are:
1. Should the presenter handle all interactions (e.g. the expanding)
or just the business form submit? In other words, should the
presenter also handle behaviors that only affect the internal state of
the view?

2. In the case of moving all behavior to the presenter, should it fire
application events in all circumstances? e.g. panel-expanded event and
so on..

3. In the case of firing app-events in all circumstances, would you
delegate the call to the actual handler method (within the same
presenter class) to the event-bus handler or would you call it
directly from the presenter?

4. Swing component architecture has View and Presenter integrated in
the same class. Would you consider using separate classes for all
components or maybe for heavy cases?

This is a presenter, not a controller. The goal is that the presenter
updates the view in response to events (listened to in the view and
forwarded back to the presenter).
Whether you'll have a onHyperlinkClicked with the presenter toggling
the view's expanded state, or an onExpanded with the presenter loading
data and pass it to the view (the view then toggling the display)
depends on which widget you use in your view (DisclosurePanel,
possibly with a LazyPanel as its child) and  how the expandable
panel's content comes from.
If you use a DisclosurePanel with static content, for instance, then
you won't have the toggling logic in the presenter, everything will be
in the view only.

 2. In the case of moving all behavior to the presenter, should it fire
 application events in all circumstances? e.g. panel-expanded event and
 so on..

On the event bus? No! only events that are deamed external (is your
panel currently firing such events?)
And remember: stay pragmatic, don't code things if YAGNI.

 3. In the case of firing app-events in all circumstances, would you
 delegate the call to the actual handler method (within the same
 presenter class) to the event-bus handler or would you call it
 directly from the presenter?

 4. Swing component architecture has View and Presenter integrated in

Swing uses MVC, not MVP. MVP is (should be?) at a higher level. You
could even keep the same presenter but give it a Swing view (instead
of GWT view) if you liked. There are precendents (a chess game in GWT
for the Web, and Android for handsets)
FYI, the new Cell widgets in GWT 2.1 have an internal presenter helper
object. This is so that you use them just like any widget, and not as
an MVP component in your MVP application (this is the business of
Activities in GWT 2.1, which are where you do MVP in an MVP
application).

It all depends what you consider your panel like (and how you'll use
it in your app): a widget or a higher-level component (business
component?)

 The way I normally do this:

In the Corresponding view class,

@UiField(provided = true)SuggestBox suggestbox;

In the constructor, before the initWidget() call, instantiate the 
suggestbox the way you want it.

 Not sure if there is such a documentation, however, one rule is that 
whenever a widget has a method say setName ( set methods), you can use 
name= in the UIBinder XML file for that widget.


May be someone else can give a better answer.

[gwt-contrib] ImageResource to html

2010-08-13 Thread stuckagain

Hi,

Is there an officially supported way to create a IMG tag as HTML
text from an ImageResource ?

Right now the only solution that I see is to create an
Image( ImageResource ) and do a toString() on it.

Many widgets from GWT support the user of setHTML, and in many cases I
need this to put an image in those locations, but there is no official
way of doing this as far as I know.

Alternatively I could use the ClippedImageImpl class, but since this
is in a impl package I can not really count on it not to change.

Any solution I found always depend on some undocumented features of
GWT ... there must be an official way in doing this that works on all
browsers.

Miroslav,

Thomas already gave me a workable solution.

I want to use ImageResources in widgets that expose a setHTML(...)
method to put something more complex in there (for example in the
ComplexButton/ToggleButton). They do not support widgets in thos
locations so I can not put an Image widget. I do not want to loose the
advantage of an ImageResource.

Yes.

There is no getHTML() method on the ImageResource interface because
the choice of how to render the data is ultimately part of the UI

Revision: 8536
Author: ncha...@google.com
Date: Fri Aug 13 06:36:43 2010
Log: Public:  Fix gwt compile errors in javax.validation.
I changed InputStreams to Strings and Local to GwtLocale.
For the Validation class, I completely gutted it,
bootstraping validation in GWT will not use this class.
