MVP best practices, how to expose a view to a presenter?
Hi guys,
I've been trying to find the best answer to the question above for a while
now. Here is the problem:
* assume you have a view with textbox and a vertical panel. The textbox is
used for searching, the vertical panel to display the found results.
In order to decouple everything, we'll define 2 interfaces:
interface ISearchView {
void populateResults (ListString results);
setPresenter (ISearchPresenter p);
}
interface ISearchPresenter {
void doSearch (String query);
}
* using the code above, I can safely bind events in view, that dispatch
business execution to a presenter (set via #setPresenter). Everything is
very clean organized.
However, when I'm implementing an Activity, here is how it would look like:
class SearchActivity extends AbstractActivity implements ISearchPresenter {
@Override
public void start(final AcceptsOneWidget panel, EventBus eventBus) {
ISearchView view = clientFactory.getSearchView();
view.setPresenter (this);
panel.setWidget (view);
}
@Override
public void onSearch (String query) {
// Execute some sync/async call.
clientFactory.searchService().search (query, ...);
// HOW DO I SEND RESULTS BACK TO VIEW??
}
}
I don't know how to access the view instance, in order to populate it with
some results. One way, which I honestly think it's uberly wrong -- is to
access it through clientFactory.getSearchView. But this basically forces me
to have a singleton scope of that view. Not acceptable, imo.
The example
http://code.google.com/webtoolkit/doc/latest/DevGuideMvpActivitiesAndPlaces.html
doesn't
include this case (by coincidence or ...)
Thanks.

Re: השב: Re: building custom event differently to avoid boiler plate coding?
You shouldn't use custom events for every possible event in your app, imo -- or, even better, identify the best events that match as much as possible. What you're suggesting by this is removing the strong-type event definitions provided by Java. Of couse, you can work with a class called Event, that merely has a String name and Object data, but this defeats the purpose of what GWT is suggesting -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Database jdbc
GWT library supports a limited subset of JRE. Some classes and packages are not and will never be supported. Those two are probably not supported, check this link: http://www.gwtapps.com/doc/html/jre.html And besides, when you're developing a client you wouldn't want to handle ClassNotFoundException, no? That makes no sense, this exception is probably thrown by the db connector implementation, you need to hide it. Same deal goes with the other exception.

Re: RequestBuilder and StatusCode=0
Same Origin Policy - you cannot call another host, or same host with different port. XML-RPC implementation will not allow you to do that. Actually, the XmlHttpRequest that is ajax core and used for all the calls will not allow you to do that (so the browser will actually limit you there). You could use REST, or have a proxy implementation (you proxy to a servlet using XML-RPC and the servlet is doing the call to that host, using http client). -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: RequestBuilder and StatusCode=0
It should return something, maybe there is a problem with the servlet. Try to do the GET by hand (wget, curl, etc) and see its response. If that is ok, maybe url is miss-spelled.

Re: Integrating GIN into HelloMVP sample from GWT
@AnnotatedWith is the annotation you're looking for. or @Named, but
personally I do prefer the first one.
http://code.google.com/p/google-guice/wiki/BindingAnnotations
Basically what you can do is replace the code below -
public Activity getActivity (Place place)
if (place instanceof GoodbyePlace) { . }
with
public Activity getActivity (@GoodbyePlace Place place) {
return new GoodbyePlace ((GoodbyePlace) place, clientFactory);
}
You will probably notice I've changed the method a bit, the
implementation selection decision (whether the method returns a
GoodbyePlace or something else) is not there anymore. So you will need
to adjust to this.
The change is a bit more subtle, you're exchanging runtime type info
with static compile time GIN functionality.

image. If they both work, then you've got a problem somewhere in your
object, so try allocating the Image at different points of the
constructor, until you've found the command that breaks the Image

You can also try a different Image, to see if the SPECIFIC Image is
the problem there, or if any image is a problem.
IOW, at this point we have no idea whether or not it's a GWT problem,

Persistence based on GAE and GWT serialization
Hi guys, I started experimenting with GAE (Google AppEngine) and I find persistence coding-style beautiful. But, there is the problem with use with GWT, since the annotations import from javax.jdo.annotations package (with obviously is unknown to GWT) and the PersistenceManagerFactory acts very similar to Hibernate's session mechanism (attaching objects returned by a query to the manager). Do you know of any *good* solutions for this matter? I ended up coding a second mirror class (like UserVO which reflects the members of User - at least the ones that are serializable) and a mapping mechanism from persistence classes = VO classes, which is used on server-side when handling RPC objects. While this may work, it increased the code needed by 170% (number taken from 1 persistence class of mine, Greeting + the two additional classes, GreetingVO, GreetingDataObject). Is there a better way than this (like ignoring certain imports)? Thanks --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

GWT more entry points on one html
Hello, I was wondering if I can make 2 or more GWT application embedded on one page. I know this is possible, but, it there a way to make them communicate with each other? It seems to me that the only way is through history tokens, but this coupling is too weak. I have to be sure that the tokens that I set will actually be processes by the second application. Moreover, did anyone try to make 2 GWT applications in 2 HTML files and, say, from one GWT app load the second HTML using the HTML widget (here I don't consider the full HTML for the second one, since embedding in such a way doesn't require head or title tag for second HTML file anymore).

compiling java sources from other projects with GWTCompiler
Hi, I have created 2 projects in Eclipse, one is intended to be the base code for the other (and many more in the future). However, I have encountered an issue concerning the GWTCompiler. How do I specify in what extra directories should it look for source code?

I have referenced the base project and the gwt specific libraries (such that Eclipse doesn't signal any errors).

Re: colorating a tab
GWT has default styles for all its widgets. For example, Button class has the style .gwt-Button. The same applies for other widgets, including more complex ones. What you see in firebug, .gwt-TabBar is the default style for TabBar, and .gwtTabBarItem (the next style on the same line) is the style for TabBarItem which is furthermore cascaded (derived) from .gwtTabBar. When you don't set any styles for a widget, it uses its default style (and further, cascades the style for complex widgets). You said the code overwrote your styles defined in main.css, this is because you don't have the required styles names in your CSS file (main.css). Otherwise, GWT would load the styles from your file. If you want other names for your styles, just define them and use setPrimaryStyleName (...). Furthermore (let's say you have a generic setting for a widget and you want further customization for a specific one), use setStyleDependentName (...). To finish, I haven't checked the following case: if I set a style name, let's say shyStyle for a TabBar, I don't know if GWT knows the styles for subitems, like .shyStyle .getTabBarItem Hope it helps, cheers. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Weird problem with shared code

You would ask 'if you get a new request back, what's the problem?' The problem is handling this request, since I have agents that handle the object inside this request, so ... request.getObject () - again, something breaks, because I used Window.alert(...) just before getting the object and again one just after. The second one doesn't get executed, but no errors, no exceptions!! I should mention that hosted mode works just fine and I am able to display the object (so it's handled correctly). Is there any problem if I use a shared package/classes (within same project) for both client and server code? How would I detect this problem since I don't get any errors?

Re: any plans to offer java bean support in future?
Why would you need this kind of code in GWT?

The following was suggested: General JavaBean support would be good which would include standardize support for property accessors, default constructors, custom editors, customizers, Beans.isDesignTime(), etc. see:http://www.instantiations.com/forum/viewtopic.php?f=11t=2174sid=301... The thing that I would need is custom editors. Would there be any plans in the future to support this kind of thing?

Re: colorating a tab
Does anybody know if it's possible to specify one or more CSS file(s)
(not styles, but rather files containing styles) from client code?
(currently I link them within HTML file).

Hi folks,
I'm new to GWT (but I read the tutorial). I need to give my tabs a
different color, and this is what I see in my firebug:
.gwt-TabBar .gwt-TabBarItem {standard.css (line 870)
background:#D0E4F6 none repeat scroll 0%;
color:black;
cursor:pointer;
font-weight:bold;
margin-left:6px;
padding:3px 6px;
text-align:center;}
.gwt-TabBar-Into .gwt-TabBarItem {main.css (line 55)
background:#EE none repeat scroll 0%;
color:#6F6F6F;
}
so the standard css background and color are overriding my locally
defined attrs in main.css.
Is it due to a bad configuration? or is it the way it is supposed to
work?
How is the main.css included? It might be a priority problem: if
main.css is loaded before standard.css (which will probably be the
case if main.css is not GWT-injected with a stylesheet in your
module's gwt.xml), given that the two selectors have the same
specificity [1], their rules are evaluated in the order they've been
loaded, so the background and color set in standard.css will override
the one set in your main.css.
Try adding an !important to your rules and see if they're applied
(with !important, the rules in standard.css won't override your own !
important rules, even though they are evaluated after them).
If that's the case, try to find a way for your stylesheet to be loaded
after standard.css (and remove the !important, which is bad practice
and recommended for user-stylesheets only [2]), either by getting your
main.css injected by GWT, or by inheriting StandardResources (instead
of Standard) and calling the standard.css by yourself...
If I were you however, I'd file a bug to have the injected stylesheet
come *before* the existing ones so that the ones already present in
the page override the injected stylesheets...

Calling an external servlet within Hosted Mode
Hello, I am new to GWT (3 months of experience) and we are running an servlet inside an application server which we want to call from within hosted mode. The problem is not necessarily local (my case), since hosted mode is great for debugging and really time-saving. The problem is as follows: You have client-side code which you run in hosted mode. After you define your interface, any servlet that implements it can be queried via RPC (through interface's methods). So you decide to make server- side code available and connect it with your applications through GWT = the servlet should handle the requests from/to the application that calls it. How do we set the target URL of the servlet path in the config module .gwt.xml ? Is it something we're missing? Since the ServiceDefTarget.setServiceEntryPoint function needs a relative, how can I specify an absolute URL for the servlet?
