Re: Are you happy with GWT?
There is no such thing as producing clean vs not clean html unless you rely on other peoples widgets. 100% of my widgets are a UIBTemplate.. of my creation… I use GWTQuery (or jquery) to add/remove elements from my widgets. Thus, the HTML is exactly as clean as any HTML that any non-gwt application would use/produce.

Re: Are you happy with GWT?
It helps the most when highly talented html5/css3/jquery people produce mockups etc.. as then translating them to GWT to get i8n, code splitting and a handy way to do an event bus + business logic all in java, is pretty darn easy Roger On Oct 10, 2012, at 6:03 PM, Brian Slesinsky skybr...@google.com wrote: The original goal of writing clean HTML was for static, document-centric websites where you could do things like run a filesystem search or a web spider to create an index of all your documents, use an HTML editor, or perhaps do a search and replace.

Re: Are you happy with GWT?
So, let me give my take on GWT (and add, I'm' happy). I use GWT, UIBinder, and JavascriptOverlayObjects to handle my tempting, i8n and client side business logic code (event bus, writing happy things like if (account.isOpen()) etc) I use 100% ajax calls to JSON endpoints.. I don't use gwt-rpc. I use GWTQuery or JSNI =- jquery for 99% of my actual DOM manipulation event handling. GWT/Java people can read it. The web designer / html / css / jquery people can read it.

Re: Are you happy with GWT?
I tend to just always start with an index.html, a reset.css main.css, and a kitchensink.js hah.. and at some point.. that grows.. and then, at some point, I migrate it to a GWT structure when I feel all the application logic, event bus handling etc warrants it. I really like java package structures for my widgets.. it helps my old brain out when things get giant. Sure, I love backbone, and handlebars, and mustache… angular.js is awesome.. but I find, most often, that there is me and then 15 java people who like Spring MVC in the room.. and so I have to migrate to a middle ground for the long term productivity of the people.

UIB click handlers, GWTQuery, and TD's ;)
I'm building an app that has a really good use case for me to have my own/raw HTML Tables (I thought of flextable.. but the api pains me). Anyway.. i'm trying to figure out something and am a bit stuck, thought the crowd might have some ideas. piece of code: GQuery td = $(td colspan='x'/); ThingyBarUIB thingyBar = new ThingyBarUIB(); thingyBar.loadData(someObject); td.append(thingyBar.getElement()); addClickHandlerToBar(someObject, thingyBar); Now.. I easily add click handlers via the method/gwtquery all is well. I'd really like, just to be.. I dunno.. closer to GWT.. to be able to use @UiHandler on the UIBinder backed via class ThingyBarUIB. I realize this 'fails' the second I do thingyBar.getElement(). Any known techniques to get around this i.e. use UiHandler? reAttach()? Thanks!

Re: jquery?
There are many (many) jQuery based live grid implementations. They are far easier to style, implement and customize than CellTable A massive strength of GWT, is the ability to model your domain objects on the client. Sure, you can do this in javascript using Backbone and other techniques, but that is beyond the technical realm of 'using jquery' Roger On Oct 27, 2011, at 7:04 PM, Andrei wrote: I wrote complex apps in both JQuery and GWT. My experience boils down to two key points: (1) 2-3,000 lines of code or less, you can do it much faster in JQuery than GWT, and the resulting JavaScript will be much smaller. More code - go with GWT. (2) If you plan to use widgets like DataGrid or trees, GWT is much more convenient. This is not a religion kind of question: these frameworks are very different, and each has very distinct advantages in certain situations. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: GWT advantages
As someone who uses GWT, but also knows HTML/CSS/jQuery… I will at least honestly (flames expected) say that developing with GWT, while great for 'java devs' is far slower and more painful than just doing traditional html/css/js development (if you know what you are doing that is) Roger On Oct 23, 2011, at 2:19 PM, Dennis Haupt wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 what about telling them why you chose to use the GWT? :) as someone who just worked on a google maps integration (for 2 month) using the GWT, i would say that the GWT gives the programmer a lot more power in general, development speed and possibilities to debug everything than any other technology that runs on the client that i've seen so far.

Detecting a checkbox click
I'm trying to detect a checkbox selection click so I can do some other work (enable a button/change some css.. trivial stuff) I tried GWTQuery, which fails (I can bind a click handler to every checkbox.. but after 1 click, CellTable appears to remove my bindings hah) I've tried overriding piles of methods.. setting handleSelection to true and overriding methods.. and in the end.. I can't seem to solve this trivial use case. i'm doing: table.setSelectionModel(selectionModel, DefaultSelectionEventManager.MyObject createCheckBoxManager()); (selection Model is single selection) I've seen posts on stack overflow about a custom checkbox manager, but none of the code compiles/works (even if I try to tweak it to get it compilable) I also tried using column.setFieldUpdater (how i've done click handler on other columns) and that as well fails to work.

Re: GWT Designer Libraries
Well.. a quick bit of objective (having used all 3) opinions. It is simple: 1) don't use GWT-EXT. 2) GXT is a pure java solution, and the only one of the 3. 3) SmartGWT is *really slick*, but it is basically a little java code, that just wraps the SmartClient javascript library (imagine a couple megs of javascript/css, with a JSNI layer on top of it). So, that leaves #2 and #3. It really depends from there how pure GWT you want your solution (GXT being the only choice there). Or if you really like the VAST choices of SmartClient widgets etc and don't mind that technically, you are just using a javascript library with a java API. Maybe I didn't make it simpler hah Roger On Nov 12, 2010, at 8:25 PM, jaybose wrote: I see in the Designer docs (and in the actual tool itself) that there are 3 promoted libraries: - GWT-Ext (http://gwt-ext.com/) - Ext GWT (http://www.extjs.com/products/gxt/) - SmartGWT (http://code.google.com/p/smartgwt/) Their respective showcases look great.

Re: Integration of hibernate with GWT
Why GWT scares me these days just a bit: I'd suggest waiting a bit (a few days, maybe even just hours) for the 2.1 RC1 release of GWT and use RequestFactory (you could go with the current M3, but many things have changed since then, so starting with RC1 would probably be better).

Re: Integration of hibernate with GWT
The general consensus is that GWT moves incredibly fast :) I should have tried convey a bit more smirk in my comment. I'm super excited for all the changes GWT brings. I just am ready for it to slow down, so it is an easier sell to the other people (management). I hate saying, The new version broke X,Y,Z No worries though :) Roger On Oct 7, 2010, at 2:09 PM, Thomas Broyer wrote: On 7 oct, 19:42, Roger Studner rstud...@gmail.com wrote: Why GWT scares me these days just a bit: I'd suggest waiting a bit (a few days, maybe even just hours) for the 2.1 RC1 release of GWT and use RequestFactory (you could go with the current M3, but many things have changed since then, so starting with RC1 would probably be better). What scares you exactly? The milestones were about building new stuff (Places, Activities, Cell widgets, RequestFactory, etc.). AFAIK, RC1 is an API-freeze release; so yes, many things have changed since M3, but only about the new stuff (and mainly about RequestFactory, and there's the new Editor stuff), and it won't change after RC1 (unless I'm wrong about the API- freeze, but I'm pretty sure I'm not ;-) ). Many things have been postponed, not to 2.1 GA, but to 2.1.1, so I think 2.1 GA will only be about having a more stable RC1. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Using Javascript Overlays vs. Manually setting up POJO instances?
The only problem I found with this interface technique (which I immediately
wanted) was this:
public interface MyEntity {
ListString getNames();
}
The javascript overlay type has to deal in JSArray's, the server can't etc.
So for all lists/collections I found it broke down pretty quick

implements the interface as a wrapper around the JSO. This wrapper is
a zero-overhead implementation (just method forward).

It always makes sense to Javascript Overlays, otherwise you loose type
safety and all the other advantages java has over javascript. It is a pain
to maintain two versions for the same entity, but the advantages far
outweigh the inconvenience. You can perhaps even build a small utility that
generates the overlays -- shouldn't be too difficult.
And finally, if it eases your pain, most people end up having DTOs and Model

on the server may be a complex hierarchy of objects; what you want on the

Re: GWT support for Grails/Groovy domain objects
Just checked this out.. it still has I guess the one sort-of problem. If you have a complex client side object.. that you have to marshall into JSON.. it is a pain point. But hey, that is what coding is about :) The reason I use a JavaScriptObject (btw, for me, it is a very large tree structure that represents a file system and has business logic). is so I can do JSONObject jo = new JSONObject(myJavaScriptObject); doPost(jo.toString()); The resty-gwt project doesn't address this client side JSON generation, it just handles making the server side endpoints (and since it uses JAX-RS, that means please include there 83 jars in your project).

Re: MVP Question
I've found after (far too many) years of engineering software, that consistency is far better than dogma. It is incredibly rare that a design pattern, taken off the shelf and dusted, works for every case. In your case, if you have a reason to create the view via the presenter, I wouldn't fear it. I would just update my diagrams accordingly and then *stick to it* in all cases. The statement I'm using Pattern X and then varying 50% of the time is far more dangerous, than modifying a pattern and sticking to it :) Roger On Jan 25, 2010, at 8:54 AM, rmuller wrote: Should not the Presenter create the view? Sometimes you need different views (based on authorization data in my case) where you can reuse the Presenter. I let the Presenter decide which view to use. I do this in the ctor. In all examples I see however, the Presenter and View are created by the parent Presenter/AppContext. Also every View has its own Presenter (1 : 1). So I wonder if my design is correct. What is the general opinion about this? Ronald -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

HostedMode/Dev Mode, 2.0 and Javascript Overlay Types
Question.. if I have an interface:
public MyInterface {
ArrayListSomething getSomethings();
}
Then on the client I implement:
public JSMyInterface extends JavascriptObject implements MyInterface {
private ArrayListSomething mySomethings;
public ArrayListSomething getSomethings() {
return mySomethings;
}
}
This works great when I deploy my app/run it in a browser.
BUT, if I run it in DevMode(2.0).. I get:
ClasscastException, cannot cast javaScriptObject to ArrayList.
So why is DevMode being a stickler/stinker hah

Re: HostedMode/Dev Mode, 2.0 and Javascript Overlay Types
Yeah, I send back JSON from the server, and eval it into the JSMyInterface
object.
What is odd, I guess, is that this works perfectly when i'm running my app in
the browser.. only DevMode picks up the class cast exception.
I mean, I *do get* that it probably should be a class cast exception haha.. but
I just can't figure out why it works just fine in the browser, but dies in
DevMode.
Because, it would be great to have it work, since that means my Server and
Client objects could share the exact same interface (that returns
ArrayListSomething) versus basically never being able to do so (since i'd
need ArrayList on the server and JsArray on the client).

How do you create an instance of JSMyInterface. If you are doing eval then i
think you have to first create an JsArray and copy the elements to the
ArrayList. This is beacuse there is now way to now that it is an ArrayList
when you using eval. But I could be wrong.

ClassCastException in DevMode on GWT 2.0 w/ Overlay Types
I'm trying to do this:
public interface Alert {
public ArrayListAlert getOtherAlerts();
}
Client Code:
public class JSAlert extends JavaScriptObject implements Alert {
public final native ArrayListAlert getOtherAlerts() /*-{
return this.alerts;
}-*/;
}
another class:
public void onModuleLoad() {
JsonpRequestBuilder jsonp = new JsonpRequestBuilder();
...
public void onSuccess(JsArrayJSAlert list) {
for (int i=0; i list.length; i++) {
JSAlert alert = list.get(i);
ArrayListAlert more = alert.getOtherAlerts();
}
}
Now.. in the browser.. this works great.
But if I run this in DevMode, I get a ClassCastException that
alert.getOtherAlerts(); is a JsArrayAlert and can't be cast to arraylist.
Any ideas why this works in the browser.. no Js errors etc.. but in hosted
mode/dev mode, it freaks out?
My goal, is to have a client side Javascript Overlay Type that can implement
that same interface as a server side object.. so marshalling to/from JSON is
made easier.. and so the server side object can have a nice basic
java.util.ArrayList to work with.
Thanks,
Roger
