Re: How to change css value's through CssResource mechanism?
Yes, I was afraid of that. I hoped to do it more elegant and be able to use preferences per Widget instance. It's however only possible to use preferences per Widget type (globally). Is it even possible per instance, such that would it be worth adding an issue about this?

Re: What is current state/fix of/for deprecated PlaceController constructor

VerticalPanel differently rendered on FireFox and Chrome
if i add some stuff to a verticalPanel nested in a SimplLayoutPanel(100%h,100%w) the result is very different on different browsers: chrome don't use the 100% and sticks all stuff in VP together. Firefox(6) and IE(6) use all the space to layout the stuff inside VP. Why does this happen? The main reason to chose gwt was to get rid of such problems. So if a table with 100%(i think that is the html translation of my VP) is rendered differntly, gwt should use a different translation to get same results, shouldn't it? the other question is how to get the same result on all browsers - i want the result of chrome: all stuff should stick together vertically arranged. thx in advance -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Extend RequestFactory to Make Use of None Primitive Types
Thanks for your detailed explanation. It helped me understand RF and GWT a little better. I ended up with a EmplyeeGWT class, which extends the MongoDB model but returns the ObjectId as String and parse the returned String to ObjectId. This seems to work. One restriction to our problem is also, that the model gets generated. The thing that bugs me is that I have an extra model and also an extra service just for GWT. We are thinking about making GWT use the JERSEY Service over RPC, but than we cant use the Objects on the client side. So far many thanks for the help. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

why getPermutationStrongName is final and writeResponse is private?
Hi, I am extending the RemoteServiceServlet and having trouble with those methods because one is final and the other is private. Is there any special reason for this? It is funny that the method readContent is protected and its counterpart writeResponse is private. This means in my subclass I can change how the payload will be extracted from the request but I can not change how the response is going to be sent. For the getPermutationStrongName case I don't want to send it as a header anymore so I had to overwrite the method checkPermutationStrongName that calls that method.

Re: Is it possible to stop the browser from interpreting control-key presses?
Vid,
Thanks very much for the reply.
I made the following example. It can either capture keyboard
events no matter what has the focus, or only if a focusPanel has the
focus, depending on the last line in onLoad()..
It captures everything on Firefox 8
It captures everything except ^W, ^T and ^N on chrome v15
It captures everything except ^P, ^O, and ^H on IE 8
I am coming to the conclusion that we really cannot capture all the
control keys on Chrome and IE.

Does the GWT magic ever fail you?
My company has taken the decision to move from Flex to HTML5/ Javascript for a corporate web-app. So far we are very impressed with GWT and are thinking of utilizing it, especially since we are mostly a Java house. My biggest concern, however, is the wonderful magic that is the GWT Javascript compiler. If this thing produces production code that is different from the development code, or if the Javascript isn't aligned with the Java, I fear we will be unable to effectively diagnose/debug the problem.

Re: Does the GWT magic ever fail you?
Well there are some cases where the development code is not the same as the executed Javascript code. You'd typically notice this around async RPC calls where the order of events during Java based debugging session is different from the Javascript. But then again this is something you'd have to design around and always be mindful of async operations. Just because it seems to work in development mode does not necessarily ensure it'll behave the same with javascript, but if you know how to properly deal with non-sequential operations, yoiu should be okay. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

server 1. http://factory-dev03.example.com:8111/
server 2. http://factory-dev109.example.com:8111/
in IE browser i am getting response with status code as '200' from
server 2 but in FireFox and Safari i am getting response with status
code as '0'.
i have gone through same origin policy (http://code.google.com/
webtoolkit/doc/2.0/
FAQ_Server.html#What_is_the_Same_Origin_Policy,_and_how_does_it_affect_GWT)
and i also added add-linker name=xs/ in application.gwt.xml file
but no luck.
below is my code for reference
String url=http://factory-dev03.example.com:8111/CustomerUI-dev03/

Question for experts: Pluggable gwt module CompileModule class XXXX.gwtar file.
OK this one is for GWT experts!! I have a GWT app that has widgets. We are shipping 5 widgets out of the box. The widgets also depend on our API which act as simple DAO pojos Now when this gets outs to customers. They have a requirement where they want to create their own widgets (as GWT modules) and use them inside our GWT app. Of course, to make things complicated, we cannot give them the source of our app or the API. Now I know a more prevalent solution here is to have a JSNI API of some sort to have the widget and our app talk to each other, document it and have it rest in peace. But we are also looking around to see if there are alternatives. For example, looking at this CompileModule class http://code.google.com/p/google-web-toolkit/source/browse/trunk/dev/core/src/com/google/gwt/dev/CompileModule.java?r=10304 Can this be used to mickey mouse our sources. It looks like this compiler will / could compile a module into a .gwtar file and in theory that might all customers would need to compile there custom module. Any thoughts? Are we on to something here or is it dead end. thanks -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Does the GWT magic ever fail you?
In my experience, debugging has been OK as long as you are savvy with dev mode.

Re: Does the GWT magic ever fail you?

My biggest concern, however, is the wonderful magic that is the GWT Javascript compiler. If this thing produces production code that is different from the development code, or if the Javascript isn't aligned with the Java, I fear we will be unable to effectively diagnose/debug the problem. Not to belittle your observation, but replace Javascript with object code and Java with C. It's a good question - how much do you trust your compiler? As a profession, we've apparently dealt with this issue in the past: One thing we do is to disable optimizations. GWT has a compiler mode for that. However, it produces more code, and one aspect of GWT is to reduce code bloat. Most real-world compilers have similar a trade-off. Another thing we do is instrument our code. For example, GWT supports the java.util.logger framework. We also employ test-driven development. There is the GWTTest environment as well as other, superb test frameworks. Has this been a problem for folks? Is there some other concern we should be aware of? I'd suggest, if your group hasn't done so, that you create a proof-of-concept, deploy it to a select group of blind men, and ask them to describe the resulting Elephant.

Re: Question for experts: Pluggable gwt module CompileModule class XXXX.gwtar file.
On 11/11/2011 01:07 PM, KD wrote: OK this one is for GWT experts!! Maybe GQuery plugins? No doubt there will be rework required. I have a GWT app that has widgets. We are shipping 5 widgets out of the box. The widgets also depend on our API which act as simple DAO pojos Now when this gets outs to customers. They have a requirement where they want to create their own widgets (as GWT modules) and use them inside our GWT app. Of course, to make things complicated, we cannot give them the source of our app or the API. Now I know a more prevalent solution here is to have a JSNI API of some sort to have the widget and our app talk to each other, document it and have it rest in peace. But we are also looking around to see if there are alternatives. For example, looking at this CompileModule class http://code.google.com/p/google-web-toolkit/source/browse/trunk/dev/core/src/com/google/gwt/dev/CompileModule.java?r=10304 Can this be used to mickey mouse our sources.

DialogBoxes and MenuBars . . . zIndexing a bad thing?
All, I'm working on my ever-evolving bit of code, and have run across something of an issue. My apologies for the lengthy prelude before I get to the actual question. Firstly, I have a full-browser-screen display - a DockLayoutPanel. Within it are a: MenuBar - NORTH FlowPanel - SOUTH Now, there's a big empty section in the middle, which is fine because that's what I want. The MenuBar looks like a typical application - File, with sub-items Open, Close, etc. Edit, with sub-items Copy, Paste, etc. I have also created a, for lack of a better term, WindowPrototype class that extends DialogBox. It has a close button, minimize, and maximize. I have not yet done draggable resizing with the corners and edges. So, my test code basically, when an item in the menu is chosen, it launches one of my WindowPrototype objects (which is mostly empty, just some text to show which item in the menu launched it). Now, of course, by default, DialogBox does not allow popping up of non- modal instances of itself over each other. The LAST one shown is ALWAYS on top - clicking on a partially hidden one does NOT bring it to the top. To get around this, I used a trick I came across on a web-search which puts a static int in the class that extends DialogBox (in my case, the WindowPrototype class), and increments it every time a new WindowPrototype is opened, or one is clicked to be brought to the top. This actually works fine as far as my WindowPrototype objects are concerned. However, when I do this, then there's a problem with the MenuBar items. If I click on a menu item, say File, then the subitems (Open, Close, etc) are shown UNDER any WindowPrototype object that happens to be in the area - the WindowPrototypes will obscure the menu items. Now that I've written half a novel, here's my question: How do I add the ability for my WindowPrototype objects to be clicked on to bring to the top, but ALSO make sure that the MenuBar items are ALWAYS on top of any/all WindowPrototypes that may be on the screen?

Re: GWT HTTP RequestBuilder
Sure you got a 200 in IE? IE should also give some error if you try to make a request to a different domain/port. Also shouldn't your code snippet use factory-dev109.example.com if server 2 is the server you want to request? Well but in general you have three options to make cross domain requests: 1.) You have to use a reverse proxy so you can make requests to external servers without leaving the domain which serves the GWT application. 2.) Make a GWT request to server 1 (works because there is no SOP) and then let your server side code on server 1 do a request to server 2 using plain java. 3.) Use JsonpRequestBuilder. But this would require some rewrite of your server 2 code as you now need to provide your data as JSON and also wrap this JSON data in a javascript callback function whose name is send by GWT to your server 2 via a GET parameter. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: DialogBoxes and MenuBars . . . zIndexing a bad thing?
Well, this is embarrassing, but maybe the answer will help someone
else who's run into the same problem.
Override the onBrowserEvent() method in my own subclass of DialogBox
as follows:
@Override
public void onBrowserEvent(Event event) {
switch(event.getTypeInt()) {
case Event.ONMOUSEDOWN:
hide();
show();
}
super.onBrowserEvent(event);
}
And that does it, with no ill effects in terms of obscuring the
MenuBar objects. Sheesh, I must now hold the record for shortest time
between someone posting and answering their own question!

[ANN] Scala+GWT 0.1-M3 released
Hello, I'm excited to announce second milestone of Scala+GWT project. Download (and then follow README instructions) from here: http://goo.gl/RZdVT Release notes (included below) can be found here: http://goo.gl/H8san Scala+GWT 0.1-M3 The third official milestone release from the Scala+GWT project. You can check release notes for previous release [here]( http://scalagwt.github.com/releasenotes). This release consists of just samples packaged along with snapshot of jars needed to build them. Those jars include our own version of both GWT and Scala. This release doesn't come with any official artifacts apart from the tarball you can download from [ http://github.com/scalagwt/scalagwt-sample](http://github.com/scalagwt/scalagwt-sample) . ### Changes since last release * Eclipse support for development mode ### Eclipse support We've integrated [Scala IDE](http://www.scala-ide.org/) so you can develop GWT applications in Scala using Eclipse. Development mode is supported. ### Known issues * many patterns in pattern matching logic are not supported (should be fixed in next release) examples include * pattern alternatives (`|`) * guard patterns (`if` guard) * in some cases (like gwtdlx sample) optimizations enabled in gwt lead to broken JS code ### Reporting issues We appreciate feedback. If you find something that doesn't work (e.g. crashes either Scala or GWT compiler) or JavaScript gives you weird results we'd love to hear about it. The most effective way of reporting issues is to modify `Hello World` sample to show your problem. Exact steps are: 1. Fork `scalagwt-sample` repo from here: http://github.com/scalagwt/scalagwt-sample 2. Clone it: `git clone git:// github.com/YOUR_USER_NAME/scalagwt-sample.git` 3. Modify hello world sample located in `src/com/google/gwt/sample/jribble/client` 4. Commit and publish your example. 5. File a ticket here: http://github.com/scalagwt/scalagwt-sample and mention your fork while explaining your issue. If you want to discuss your problem before reporting it, join [scala...@googlegroups.com](http://groups.google.com/group/scalagwt). ### What if I don't know GWT? That shouldn't be a big problem. You've got Scala source code for samples that show basic functionality and provides basic setup. You may want to start with changing hello world sample, recompiling it and testing in a browser. ### What if I don't know Scala? You might still want to check out samples to see how they might look in a language other than Java. We'll be cutting a lot more of the boilerplate code once GWT libraries and APIs receive enough of Scala's [pimp-love](http://www.artima.com/weblogs/viewpost.jsp?thread=179766). ### Need help?

Re: Using DockPLayoutPanel - can I get an autoexpanding south widget?
Don't use DockLayoutPanel. Use LayoutPanel instead. It gives you complete control: you can make any area expandable. Personally, I never use DockLayoutPanel: it adds no useful functionality compared to LayoutPanel, while the size of the compile code jumps if you use both of these widgets. If you want the menu to wrap, however, the best solution is to use a FlowPanel (or HTMLpanel, if you use UIBinder), and CSS rules for your menu items. Then the browser will do the work for you. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Dart and GWT
Hi Eric, I saw the Dart Editor (Linux, Mac, Win). It's a standalone editor based on Eclipse UI. Is there a real Dart plugin for Eclipse ? If not, do you plan to provide one ? 2011/11/11 Eric Clayberg (Google) clayb...@google.com See... http://googlewebtoolkit.blogspot.com/2011/11/gwt-and-dart.html The Google Web Toolkit team has been asked recently about our plans following the announcement of the Dart programming languagehttp://dartlang.org/ a few weeks ago. Dart and GWT both share the goal of enabling structured web programming. In fact, many of the same engineers who brought you GWT are working on Dart. We view Dart as an ambitious evolution of GWT’s mission to make web apps better for end usershttp://code.google.com/webtoolkit/makinggwtbetter.html#introduction, and we’re optimistic about its potential. As Dart evolves and becomes ready for prime time, we anticipate working closely with the GWT developer community to explore Dart. Meanwhile, rest assured that GWT will continue to be a productive and reliable way to build the most ambitious web apps — and even games like Angry Birds.

As I understand it, in the case of the DevMode, only the common, browser-independent, part would be binary (there might not even be a need for glue code, or only for calling back to the JS engine) and everything else would be done in JS; so it'd save us from compiling one version of the binary component per Gecko SDK version, only one per OS. So releasing for a new version of Firefox would mean, in the best case, only bumping the maxVersion in the update.rdf; something that can be done by anyone locally, and you no longer have to wait for the SDK to be released. That'd also make it possible (and really easy) to test/use the plugin on beta or aurora versions. All the calls from the plugin to the JS engine will have to be proxied through the JS code (for example, I didn't see how to allocate a JS string), which will mean a lot of boilerplate and a likely performance impact. So, assuming the finalizer problem can be overcome, I think it would be possible but would be a lot of work to get worse performance. Searching a bit on the MDN, I don't see how the finalizer issue could be worked around, so I guess it's a show-stopper. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
