Re: if change css, need restart the server?

2012-12-23 Thread RyanZA 
Documentation is really bad for CSS resource - don't think there is even 
any CSS code in the documentation itself...

Css file my.css would be placed in the same folder as 'MyResources.java' 
file

If my.css looks like the following:

.className {
 width:100px;
}

.something {
 width: 200px;
}

then MyCss interface must look like this:

interface MyCss extends CssResource {
  String className();
  String something();
}

Now in your actual code, where you have addStyleName("something") before, 
it must now be addStyleName(resources.css().something())

GWT will now create the minimum css for that style and inject it in.

For more information, we found if using jetty server and development, 
changing css will reflect in browser in development mode, if using 
externaml sever, then even using development, changing css will not cause 
browse UI change.

I have a look about cssResources at 
https://developers.google.com/web-toolkit/doc/latest/DevGuideClientBundle#CssResourceCookbook
but feel very complicated, any simpler tutorial to teach about using it?

in its documentation,

in a normal css file, there should be many class name, so how to insert the 
classname in addStyleName()?

no luck in refresh twice, maybe really need to change to CssResource or 
ClientBundle.
I am using maven, my css placed under public folder as the first post 
mention, change css in that place will not be reflected in development 
mode, still need restart server everytime, very trouble.

You can't set a gradient as a background *image* - only images can be set

When and where should I call:
IGradientStyle.INSTANCE.style().ensureInjected()  ?

I called IGradientStyle.INSTANCE.style().ensureInjected() 
just before 
mySimplePanel
.setStyleName(IGradientStyle.INSTANCE.style().backgroundtoolbar());
but without any effect.

@Andrei:
What kind of definition should I use instead?
I tried IE and Chrome.

GWT application works perfectly fine in hosted/dev mode but its not working in production mode.

2012-12-23 Thread Vasu 
My application on which I am working on, is working fine in dev / hosted 
mode. But when its compiled by GWT compiler and deployed in production, it 
was just showing blank. It was not showing any javascript errors on browser 
(firefox error console). I tried and confirmed searched on net but I didn't 
find any damn solution. So finally I decided to cleanup unwanted dead code 
in the project which is in way good thing but it took me a while to 
identify the issue. The issue was I was defining a property (

) 

inside one of the module (i.e. .gwt.xml) but was not setting any value 
(haven't done 



. When I removed this unwanted line, and deployed the code after "GWT 
compile" it started working. It was unbelievable for me to find this 
problem, so I reconfirmed it by adding just define tag and removing it 
multiple times.  
   My problem is solved now , but I feel there should be some 
way to identify such a situation (as it took me big amount of time to 
investigate the root cause and identify the solution). I do agree that one 
should take care of and remove unwanted/dead code, but still if it can be 
identified by the compiler and it throws error that will make developers 
life easy. So posting it here to understand what others have to say on this.

Re: Background css gradient

2012-12-23 Thread Andrei 
I think you have wrong definitions of gradients, so browsers just ignore 
them. You don't need "literal" for non-IE browsers. Google a "CSS gradient 
maker" and use its output - I never had problems with gradients.

Have you called IGradientStyle.INSTANCE.style().ensureInjected() ? Only 
when calling this method the CSS will be injected into your html page. Once 
it is injected this method becomes a no-op.

Re: Background css gradient

2012-12-23 Thread Marco 
I tried this way now:

*GradientStyle.css*

.backgroundtoolbar {
  background-image: literal("-ms-linear-gradient(top, #000 20%, #fff 80%)");
  background-image: literal("-moz-linear-gradient(top, #000 20%, #fff 
80%)");
  background-image: literal("-o-linear-gradient(top, #000 20%, #fff 80%)");
  background-image: literal("-webkit-linear-gradient(top, #000 20%, #fff 
80%)");
  background-image: literal("linear-gradient(to bottom, #000 20%, #fff 
80%)");
}

public interface IGradientStyle extends ClientBundle {
 public static final IGradientStyle INSTANCE = 
GWT.create(IGradientStyle.class);
 @Source("GradientStyle.css")
Style style();

public interface Style extends CssResource{

String backgroundtoolbar();
}
}

mySimplePanel
.setStyleName(IGradientStyle.INSTANCE.style().backgroundtoolbar());

Again, no effect. Have I missed something? Is there a other better way to 
have a simple gradient background?

Re: using autobeans in a gwt-rpc call

2012-12-23 Thread RyanZA 
Really great option if you have the flexibility to use it - use RESTful 
services - https://www.google.co.za/search?q=RESTful

On the server side you can use Jersey(JAX-RS) to make REST services that 
can use POJOs to automatically map to JSON/XML - http://jersey.java.net/ 
and http://jackson.codehaus.org/
On the GWT side, you can use RestyGWT which understands Jersey annotations 
- http://restygwt.fusesource.org/
For persistence if using appengine, you can then use 
https://github.com/icoloma/simpleds which uses jackson to map to JSON also

This gives a VERY nice stack that is easy to use, and allows your services 
to be accessed by non-GWT clients, as creating clients for RESTful 
services+JSON is very simple. This allows things like iOS clients or 
java-Android clients.

Re: AJAX crawling scheme

2012-12-23 Thread RyanZA 
You generally need to do more than #! as GWT is all javascript..

However, cleanest approach is to make your own PlaceHistoryMapper - you can 
then control exactly how places are turned into tokens.

You will also need to provide html snapshots though, which is a lot 
tougher...

Re: Gwt 2.2, guice and gin...

2012-12-23 Thread Avanish Raju 
Please help me. I've still not been able to resolve this.

At least, any pointers as to why this might be happening? I tried to search
online, but this thread is the only reference to this issue that I found.
I've even tried to build guice from svn head, and added gin- and gin-src-
jars to my project. I still get the same error about:

 No implementation for
javax.inject.Provider was
bound.

Also, currently, I'm only using GIN on client side, and haven't done any
server-side Guice setup. Could this be the cause for my problem? In other
words, will Gin only work if I'm also using guiceServlet configured?

Thanks,

This is not how one uses a CssResource. You have to call the foo() method 
of your CssResource interface.

.foo {
  background-image: literal("-ms-linear-gradient(top, #000 20%, #fff 80%)");
  background-image: literal("-moz-linear-gradient(top, #000 20%, #fff 80%)");
  background-image: literal("-o-linear-gradient(top, #000 20%, #fff 80%)");
  background-image: literal("-webkit-linear-gradient(top, #000 20%, #fff 80%)");
  background-image: literal("linear-gradient(to bottom, #000 20%, #fff 80%)");
}

OR

@def FOO_GRADIENT_COLORS #000 20%, #fff 80%;
@def FOO_GRADIENT_OLD top FOO_GRADIENT_COLORS;
.foo {
  background-image: -ms-linear-gradient(FOO_GRADIENT_OLD);
  background-image: -moz-linear-gradient(FOO_GRADIENT_OLD);
  background-image: -o-linear-gradient(FOO_GRADIENT_OLD);
  background-image: -webkit-linear-gradient(FOO_GRADIENT_OLD);
  background-image: linear-gradient(to bottom, FOO_GRADIENT_COLORS);
}


I have set the css to my SimplePanel:

mySimplePanel.setStyleName("foo");


Sadly there is no effect. The panel is just white.


Any ideas?
