Re: Gin, SingleInstanceProvider?
Maybe this will clarify what I was looking for:

I implemented the SingleProvider, here is the test(FooBar isn't a
singleton):
public void testProviderInGinjector() {
ProviderFooBar fooProvider = injector.getFooBarProvider();
assertNotSame(fooProvider.get(), fooProvider.get());// A Provider
returns always new instances
}
public void testSingleProviderInGinjector() {
SingleProviderFooBar fooSingleProvider = injector
.getFooBarSingleProvider();
assertEquals(fooSingleProvider.get(), fooSingleProvider.get());// A
SingleProvider returns always the same instance

Re: Next GWT Designer release
We have spent a lot of time working on that and will continue to do so. Most of the time is spent in starting up the GWT dev mode environment that is used to create and render the widgets. We are exploring a number different strategies (caching and so on). In the past, we always used a customized, optimized version of GWT within GWT Designer to make it faster at the expense of always being 2-3 week behind a GWT release. A lot of effort has gone into making GWT Designer work directly with the unmodified latest version (or even the GWT trunk) and moving our custom optimizations into GWT itself (which has to be done very carefully). We are very aware of the GWT Designer startup issue and will continue to whittle away at it until it achieves a reasonable speed. -Eric On Feb 4, 6:11 am, cri chuck.irvine...@gmail.com wrote: With GWT Designer integration being a focus of the upcoming GWT/Plugin release, I hope some time will be (or has been) spent on speeding up the time it takes to bring up the GWT design window on a GUI class.

CellTable with all rows and columns being of same Type: eg. Thumbnail Grid View
Hello Everyone, Let me start with a concrete example: Thumbnail Grid view ! we have custom cells (images + text), layed out in X column and Y rows. with CellTable, when we are Displaying List of Items for example Contacts, each Row represents a Contact, and each Column represents a Property of Contact: eg. Address, Name but for Thumbnail Grid View, row and columns are not conceptually equivalent to CellTable row and columns. because for Thumbnail Grid View, our unit of display is not row, it is cell. and we might repeat this cell in X number of columns and Y rows. do you know what is the correct way of implementing this with CellTable ? I was thinking of using a container class C to hold X number of items, and break my items into X chunks. in other words, every X items, becoming a new type C, and displaying this C type in a CellTable, instead of individual items. can you think of another way to implement this ?

Re: Gin, SingleInstanceProvider?
Here is a simple way to do what you want:
public class LazyT {
@Inject ProviderT provider;
private T instance;
public T get( ) {
if (instance == null) {
instance = provider.get();
}
return instance;
}
}
public class Main {
@Inject LazyThing thingA;
@Inject LazyThing thingB;
Main() { }
}
And then this passes:
Main main = ginjector.getMain();
assert(main.thingA.get() == main.thingA.get());
assert(main.thingA.get() != main.thingB.get());
I have tested it with Gin trunk, but it needs the fix mentioned by
Thomas in:

Re: GWT with Hibernate and Oracle
Hi I checked the link that you sent and this is will work of course but you will have to create a lot of DTO objects for your application and map the POJO objects from Hibernate to the DTO which will require a lot of coding. The example should work, your DTOs should be serialized, Now what I don't understand is that if you're using Hibernate why use JDBC directly?. You can get a Connection to your database from the Session object or create an a SQLQuery. From what I'm reading it looks like you're using java.net.Socket on the GWT Client side and this is not a valid class.

Is it possible to convert ImageResource to ImageElement?
Hi there, I´m playing around with the new Canvas API in GWT 2.2. Great stuff! And I want to use a ClientBundle to get my Images for the Canvas, to use it as some kind of image preloader. But the ClientBundle is giving me ImageResource objects but I need ImageElement objects for the Canvas. This is the only way i figured out to add images on the canvas: ImageElement imgMap = Document.get().createImageElement(); imgMap.setSrc(some URL); contextMap.drawImage(imgMap, x, y); It doesn´t seem to be possible to add normal GWT Image objects to the canvas, or am I wrong? But I would like to use the ImageResource from the ClientBundle. Any ideas? Maybe I should try a different approach for an Image preloader? cheers, Michael -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

this is the class:
static class RequestFormData
{
static public void PrepareRequestFormData(RequestBuilder rb, String
variableName, String contents)
{
String boundary = MakeBoundary(variableName, contents);
rb.setHeader(Content-Type, multipart/form-data;
boundary=.concat(boundary));
rb.setHeader(Content-Length,
String.valueOf(ComputeContentLenght(boundary, variableName,
contents)));
rb.setRequestData(getRequestData(boundary, variableName, contents));
}
static private String getRequestData(String boundary, String vn,
String c)
{
String r;
r = --;
r += boundary;
r += \r\n;
r += Content-Disposition: form-data; name=\;
r += vn;
r += \\r\n\r\n;
r += c;
r += \r\n--;
r += boundary;
r += --\r\n;
return r;
}
static private int ComputeContentLenght(String boundary, String vn,
String c)
{
/* header:
--boundary\r\n
4 bytes +
strlen(boundary)
Content-Disposition: form-data; name=variableName\r\n
41 +
strlen(variableName)
\r\n
2 bytes
contents\r\n
2 + sizeof(contents)
--boundary--\r\n
6 + strlen(boundary)
*/
return 55 + 2 * boundary.length() + c.length() + vn.length();
}
static private String MakeBoundary(String vn, String c)
{
int i;
String boundary = Xd2Zy5fb;
do
{
i = c.indexOf(boundary);
if(i -1)
{
char x;
x = c.charAt(i + boundary.length());
boundary += (x + 1);
}
} while(i -1);
do
{
i = vn.indexOf(boundary);
if(i -1)
{
char x;
x = vn.charAt(i + boundary.length());
boundary += (x + 1);
}
} while(i -1);
return boundary;
}
}

Re: How to Display a Loading message when transitioning between Activities and Places ?
I solved this way:
1) i hard code a DIV (id=wait_glass1) in my html, and set this
style for it: style=position: absolute; visibility:visible; top: 0px;
left: 0px; width: 100%; height: 100%; background-color:#00;
filter: Alpha(Opacity=50); opacity: 0.5;.
2) hardcode a second DIV (id=wait_glass2) with
style=position:absolute; left:0px; top:0px; width:100%; height:
100%;, this DIV contents my loading, please wait message
I hardcode both DIV's in html because them are showed inmediatly,
before GWT loads
3) surround your delayed code this way (for example):
public void onModuleLoad()
{
// force image preload
Image.prefetch(img/carro.gif);
Image.prefetch(img/centro.gif);
Image.prefetch(img/der.gif);
Image.prefetch(img/izq.gif);
GWT.runAsync(new RunAsyncCallback() {
@Override
public void onSuccess()
{
code to be executed
delayed ..
RootPanel.get(wait_glass1).getElement().getStyle().setVisibility(Visibility.HIDDEN);
RootPanel.get(wait_glass2).getElement().getStyle().setVisibility(Visibility.HIDDEN);
}
public void onFailure(Throwable reason)
{
Window.alert(error loading program);
}
});
}
this code shows wait_glass1 and wait_glass2 during download, and hides
them after all delayed code is downloaded and executed, and after all
your images are downloaded

it is a common practice to display a Loading message/icon
when we have an operation that possibly would take some time to complete.
for example when retrieving data from Datastore, etc.
I was wondering how we can do the same for Activities/Places.
in GWT MVP, when navigating from one place to another,
an activity stops and another one gets started,
however at times there is a slight delay in between.
do you have any suggestions on how we can display a Loading message,
when transitioning between Activity/Places ?
Thank You

[gwt-contrib] Introduces SkipInterfaceValidation annotation. (issue1338807)
Reviewers: bobv, rjrjr, Message: I initially thought about skipping validation of the ProxyFor/ProxyForName/Service/ServiceName if the class is annotated (i.e. don't poison the RFIV, or fail in the RequestFactoryGenerator, if the ProxyFor/etc. annotation is absent), and allowing the annotation at the class level as a shortcut to annotating each and every method; but I don't think it's necessary: it's a very advanced feature, so you have to pay a bit for using it (and for the ProxyFor/etc. annotations, I simply do no longer think it's a good idea to bypass the check; my initial use case was using a naming convention outside the contexts/proxies, see http://code.google.com/p/google-web-toolkit/issues/detail?id=5761 ) We're doing two kind of things where this feature would help: 1. we need to wrap our domain objects before passing them to the service's domain method, which means the argument types don't match what RFIV expects (i.e. WrapperDomain instead of Domain); the use case is: we have embedded objects that we need to expose as EntityProxy-s; the domain object has no reference to its owner entity, so we have to use a wrapper object to pair the entity and the embedded objects (and the path from the entity to the embedded so the synthesized ID has enough information to let us implement Locator#find. 2. we add synthetic property methods to our proxies that don't match any method in the domain object. The use case is described at https://groups.google.com/d/topic/google-web-toolkit-contributors/G-O4tFXD3U4/discussion . I forgot to mention another usage of those synthetic, lazy-load, methods: when the reference is in a sub-object and we use an RFED; without them, we would have to retrieve the referenced entities before we edit() or display() the parent object, and give the mapping between the IDs (that we have in our domain objects) and the objects previously retrieved (remember, via a second HTTP request!). When you have a complex graph with several such references scatter all over, it can become very complex; much more than those synthetic methods. Don't hesitate to ask if you want more info, or even source code. We're currently bypassing the whole ResolverServiceLayer to skip the RequestFactoryInterfaceValidator (but then resolveClientType is a bit difficult to implement). With this patch, we would annotate our synthetic property methods or otherwise rewritten (signature-wise) service methods and fully benefit from the ResolverServiceLayer. Description: Introduces SkipInterfaceValidation annotation (I'm not too found of the name, it could be named @Synthetic for example). When a service method or property method in a context/proxy is annotated, the RequestFactoryInterfaceValidator (RFIV) won't be poisonned if it cannot find a compatible method in the domain object. This patch also fixes tests, that can fail for bad reasons (Domain mapped as EntityProxy but missing getId/getVersion/findDomain, and that's not what's being tested) and remove the proxyFor property in EntityProxyModel because it's not used anywhere.
