Re: Mouse Cursor Position
I would suggest adding a mouseMove Listener to the root panel of the GWT application. That way you get informed about every mouseMove - and the new position. Of there is no event within your time interval (2 seconds), the mouse has obviously not moved and the position is the same as before.

Re: How to support multiple custom cache manifest for offline use in GWT, on a user by user basis?
Hi David, Let me point out the steps I have performed to solve a similar task. A while ago I wanted to create different manifest files - specific for the browser type - because I did not want to cache all HTML files (even the ones that are not relevant for a specific browser) in its cache. Here is what I did: 1.) Create a custom GWT-Linker by extending the class SimpleAppCacheLinker. 2.) Register this new Linker in the module.gwt.xml 3.) Inside the linker i have put code for generating different manifest files 4.) On every build the linker gets called and new manifest files are generated. 5.) Paste a UID as a comment in every manifest and change the UID on every build process. Your browser will only validate the cached files, if the manifest file has changed... 6.) Within the applications main HTML file I reference the manifest like html manifest=myApp/appcache.nocache.manifest 7.) In order to return the correct manifest file to the caller (the browser) I added a simple ServletFilter to the application. 8.) This ServletFilter listens for requests for the file appcache.nocache.manifest. If such a request is detected - the filter reads the HTTP Header Attribute to detect the typ of the calling browser. 9.) Last but not least the filter redirects the response to the correct, appropriate manifest file. I think with little adaptions this approach may be usesful for your problem as well. Hope this helps!

JPA2 Support inside Legacy and GWT Application
Hello, I am currently facing the task of adding a new database layer based on JPA2 to both a standalone Java application as well as a GWT project that is based on the business logic provided inside this standalone Java application. (Basically GWT acts as the UI-layer by providing service methods for accessing certain methods of the business logic...) The GWT application is running ontop of Tomcat 6 (so no EJBs, ... - But EJBs would not work in the standalone application... so no need to feel pitty ;) Right now the database connectivity is solved by direct SQL commands. The standalone application has to be runnable without the GWT project as well. Especially the JPA2 connectivity. So here is my approach so far, which I would like to discuss. 1.) Create DB-Entitiy objects for all needed DB-Tables. 2.) Create some kind of static class that holds the EntityManagerFactory for our persistence context. 3.) As soon as any method (inside the business logic of the standalone application or within a GWT service class) needs to create/update/read/ delete data from the database, use the EntityManagerFactory from the static class to obtain a new entitymanager. 4.) Perform the transaction and close the entitymanager at the end of the method. 5.) Objects transferred between the server and the client are simple DTOs. No annotations or anything. The service methods will wrap the objects obtained from the database into the corresponding DTOs. The update process works the other way round. This way both the standalone application as well as the GWT application would work fine, am I right? No problems with parallel sessions, ... or am I overseeing anything. It is kind of the same approach Google Guice suggest by creating a new Entity Manager for every HTTP Request with the help of a ServletFilter. But honestly I can not see the need for dependency injection in my scenario. The only difference is, that my solution does not create an EntityManager automatically with the help of a ServletFilter, but manually through the EntityManagerFactory obtained from the Singleton class. Please share your comments, advices, hints on the proposed approach. ;) Thanks in Advance for your help!

Re: JPA2 Support inside Legacy and GWT Application
Hi Jens, Thanks for the quick reply. I have the creation of DTOs and the JPA query language in mind. Thanks for pointing out. Our DB-Accesses are very straight forward, so no really complex queries. Just one more thing... Why is it important to have one EntityManager instance per request? What would the consequences be? If I am only allowed to have one EntityManager from the top till deep down in the business logic maybe it would be better to write a servlet filter and keep the EntityManager as a ThreadLocal variable for this request... Greetings Stefan On 19 Sep., 12:26, Jens jens.nehlme...@gmail.com wrote: Should work.. just make sure you only have one EntityManager instance per request. I use a command pattern so I have one place where I can handle the transaction (create transaction before command handler executes and commit afterwards). But command pattern as well as DTO's leads to lots of classes for a simple server request...don't know if I would choose it again (command, command result, command handler, JPA entity, DTO class, possibly DAO class). Also JPA's query language (JPQL) does not support everything that native SQL supports so you have to keep that in mind (but sure you can also execute native SQL queries with JPA if there is no other possibility). Currently I am looking into myBatis (http://www.mybatis.org/) for a new projects. It uses native SQL and has some nice code generator support. Maybe you should take a look at it, as you already have native SQL for a given database. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Application Cache Events
Hello, I am currently experimenting with the application cache. After creating a appcache.manifests for the different browser versions I am wondering if there is a way to listen for the application cache events inside GWT? Using Chrome Dev Tools you see a lot what is going on with the application cache. For example things like: Document was loaded from Application Cache with manifest XXX Application Cache Checking event Application Cache Downloading event Application Cache Progress event (0 of 43) XXX ... Application Cache UpdateReady event Any chance to capture these events inside GWT? My further goal is to detect dynamically if my application is on- or offline. Thanks in Advance!

Re: HTML5 Offline Web-Application
Hello Shwan,
Thanks for you reply!
@1: Chrome Dev Tools are great. Nevertheless I was thinking about
reading the online/offline DOM flag from within my client code to
detect whether the application is online or offline.
@2: Great idea. Servlet filter, intercepting requests to
appcache.nocache.manifest and returning the correct one (depending on
browser version) seems pretty clear to me.
But I am really stuck on how to write the linker class that generates
different appcache.nocache.manifest files for every permutation.
I am using the class SimpleAppCacheLinker (see below) provided within
a GWT mobile sample.
This linker get called once during the GWT compile - right after all
permutations have been compiled. And not, as you said once for every
permutation. GWT API says that the link() method gets called once -
and only once - too.
Can you point me in the right direction on how to generated manifests
for different permutations?
Maybe even a code snippet?
THANKS!
Greetings
Stefan

Re: HTML5 Offline Web-Application
Sorry for getting confused with the API. I did not want to sound
rude...
Using the @Shardable annotation, the method link(...) gets called for
every permutation.
The paramter ArtifactSet artifacts contains exactly those files I need
and want to add to my offline manifest.
Sadly I am stuck on getting the user.agent of the permuation, the
method link has been called for.
Using the LinkerContext returns null for the property user.agent.
The only solution I have come up so far is this:
(It generates an offline manifest for every user.agent. So after
compiling I have six different manifests in the WAR directory. I plan
on writing a servlet filter that returns the correct one upon
requesting the offline manifest...)
@Override
public ArtifactSet link(TreeLogger logger, LinkerContext context,
ArtifactSet artifacts,
boolean onePermutation)
throws UnableToCompleteException {
ArtifactSet toReturn = new ArtifactSet(artifacts);
for (CompilationResult compilationResult :
artifacts.find(CompilationResult.class)) {
for (SelectionProperty property :
compilationResult.getPropertyMap().first().keySet()) {
if (property.getName().equals(user.agent)) {
String userAgent =
compilationResult.getPropertyMap()
.first().get(property);
System.out.println(userAgent);
// Create the general cache-manifest resource
for the
// landing page:
toReturn.add(emitLandingPageCacheManifest(context, logger,
artifacts, userAgent));
}
}
}
This calls a method for generating a offline manifest for every
user.agent. But there gotta be an easier way than to navigate over the
compilation result?
Any ideas!
Thanks!
Stefan

Re: HTML5 Offline Web-Application

Upon requesting the offline manifest, the filter redirects to the

offline mode does not work...

HTML5 Offline Web-Application
Hello, I already succeeded in tweaking the simpleappcachelinker class a little bit to create a first simple Offline application. Now I have two question concerning this topic: 1.) Are there methods inside GWT to read HTML5 Offline Web Appliation events? (Online? Offline? Finished Caching? Caching not necessary? ...) 2.) appcache.nocache.manifest contains all HTML files generated by GWT. The effect is that a user calling the web app from FireFox will cache all HTML files inside this browser. Altough he/she would only need the FireFox HTML file. Difficult topic because creating the manifest happens during linking, browser detection during runtime. Any thoughts on this? Thanks for your help!

I was too quick to draw my conclusions. I copied both the SimpleCacheAppLinker code as well as the AppCacheLinker code to my project and now it works.

Canvas Multi-Touch Simulation for FireFox
Hello, I am currently developing a small prototyp using the HTML 5 canvas element included in GWT 2.2 The focus of this prototyp is in evaluating the multi-touch event of the HTML 5 canvas. Basically I have some questions about HTML 5 and multi-touch and I hope someone can help me answer them! ;) 1.) Is the touch event mechanism (Touchstart, touchmove, touchend, touchcancel) HTML 5 or specifc to every browser like FF. Chrome, IE, ... Is a multitouch canvas specified by HTML 5 or be the browser vendors? 2.) Is there a way to simulate multi-touch without having a multi- touch monitor/trackpad/... I am thinking about something like connecting two or more mice to the computer to simulate multiple fingers. I have already seen and testes such approaches for mt4j or the MS Surface.

Re: To GWT or Not to GWT
Hello, After reading the whole thread - it has gotten quite large, I would like to share some thoughts, too. ;) Personally I regard creating something like a desktop JRE for GWT to be a suboptimal solution. From my point of view all GWT application/ projects/... already have a common base - HTML 4, CSS and JS. Every new GWT application is based on these three components. So in a certain way this can be seen as a - and I quote you - desktop GWT JRE. Creating a common library with GWT logic that may or may not be needed by every new application sure sounds promising when thinking about filesizes and transfer time. After all this library would have to be transferred only once to the client and live on inside the browser cache for some time. BUT the code inside this library would not be optimized for your specific application. Moreover it would contain code for all possible browsers supporting all of their weird interpretations. One of the strength of GWT is the compile step and the optimization of the produced code for one specific application - one specific problem. And for the next project the code will be optimized again - but maybe in a different way. So personally I can not honestly see your problem. Greetings Stefan On Dec 16, 3:31 pm, bkard...@gmail.com bkard...@gmail.com wrote: I think you're still not understanding the distinction Christian, since GWT is Java let's try to use an appropriate Java analogy rather than .exe's... The distinction is more like whether a class is on the environment/server classpath (even part of the JRE itself like Swing) vs each app having a distinct copy of it. The JRE is kind of the most obvious example - in theory, we could compile up only the relevant bits of the JRE and deliver one hyper-optimal download for each app. Given Java's classloading architecture, anything above the JRE level is probably less analogous. So that's kind of the two things that I'd like to see... 1) Some way to deliver a single sort of desktop JRE which would include the GWT JavaScript JRE stuff + an exposed base of the whole WT part which the rest of my projects can just use... Just like the regular JRE, I'm totally willing to say go ahead and get the whole thing, because I only have to get it once per version no matter how many programs I develop against it... I can stick it on a CDN and I'll never have to re-get, in fact, if more people did it, most apps would never even pay the initial cost. Even in IE6, the memory required for that whole kit to be there once loaded is comparatively negligible. 2) (ideally) Something more or less analogous to a specialized URL classloader for this (and potentially of things like it) where I can provide a URL to point it at some GWT lib resource, effectively putting it on the classpath and accounted for by the compiler by not attempting to optimize it, but merely reference.

Actually I would reformulate it another way : I compare the problem to an .exe that is using .dll files If you build a new .exe app you may reuse existing .dlls I understand that this is not possible with GWT as when you compile your GWT-app, you compile the entire code in once. The big advantage is the javascript optimization. But would it be possible in the future to allow building GWT-app by reusing previously built GWT-dlls ? This implies that those GWT-dlls have a know API-contract used by the main GWT-exe In a distributed and disparate environment this has been solved with the SOA concept using SOAP, an ESB,... with all the paylod and complexity allowing the communication between the components. So I don't have in mind an ESB solution, as the environment is not distributed nor disparate. But in the context of GWT, would it be nonsense (for the future of course) to build new app by using pre-compiled building blocks having their own life-cycle independant of each other ?

Re: To GWT or Not to GWT
Very brave of you to point out that this discussion is meaningless. Especially when your understanding of GWT is to have one widget on the same page at a certain time. Good luck with that. I am very eager to see one of your applications having one label or one button or one textbox on the same page. ;) So, and now back to the topic: I think we all got a little bit mixed up with the wording widget - composite - gadget. Because of that I think - or at least I hope - you are not referring to a widget but to a more complex user-built GUI object - an composite. And honestly I can not see anything wrong with having different composites on one page. I would go even further and say that this behavior - having independent composites within one page - should be the only way to go for it. Greetings Stefan On Dec 17, 10:30 am, Matt Hill matt2...@gmail.com wrote: I don't understand the discussion of widgets here because GWT is clearly not designed to be used for multiple embedded widgets on the same page. You can do it, but it'll require using some lesser-known features and maybe even hacks to get it to run as get the initial download for all of the gadgets as small as it would be with other libraries.

GWTCanvas and IE8
Hello Everybody,
Currently I am trying to use the GWTCanvas from gwt-incubator-2.1.0
(together with gwt2.1).
All I want to do right now is a simple proof on concept by drawing two
rectangles.
Does not sound very fancy, but even this simple task fails in IE8.
I started by creating a new GWT project using the Eclipse Plugin (The
HelloWorldService template).
Then I placed basic GWTCanvas code into the onLoad method.
code
/**
* This is the entry point method.
*/
public void onModuleLoad() {
GWTCanvas canvas = new GWTCanvas(640, 480);
canvas.setLineWidth(3);
canvas.setStrokeStyle(Color.RED);
canvas.strokeRect(30, 30, 100, 100);
canvas.strokeRect(60, 50, 200, 200);
RootPanel.get(mainArea).add(canvas);
}
/code
Works perfectly in FF 3.5, Chrome but shows an empty page in IE8.
Compatibility mode in IE7 show one rectangle, but only one. Changing
from HTML Standard to Quirks mode did not have any effect.
Am I doing something obvious wrong?
I have found no information stating that the GWTCanvas does not work
with IE8.
Moreover the provided sample [1] from google incubator work perfectly
even in IE8.
What are the guys doing differently? ;)
Thanks in Advance for both your time and your knowledge!
Greetings
Stefan

Re: Composite Library
Thanks a lot Steve! I just overlooked one simple detail - include the source files. Now it is working perfectly! Currently I am just pondering about two follow up questions: Say I have kind of a GWT Base project. Including CSS, Entry Point, ... What would be a recommended approach to create an inherited lets say extended project based on the base project? Or is it better to create a base widget library which can be used by both a GWT Base project and an Extended Project? Actually I prefer this way. Nevertheless this does not answer the question on how to deal with for example CSS resources... They are specified by each projects HTML Start page. So how can I use the one from the base widget library? Sure I can manually include the CSS inlcude to HTML but that is a step that is potentially failure prone... Thanks in Advance for your help!

Re: Session Management on server side through timer task
Hi Sunny, You need some kind of polling solution. For example an invisible frame on the client side that asks the server periodically (f.e. every second) if the session is still valid. If not, then this invisible frame will display an alert box on the client side informing about the session expiration.

Re: Session Management on server side through timer task
@Sunny: Although you found the thread on the server there is no way (except polling) to inform the user/client/browser about the occurrence of this event. @Bruno: Nice solution, but it is basically a counter/timer on the client side. Please correct me if I am wrong. You specify a time and after the time has run off, the user gets logged off. Except if his is clicking a special button in the small window of opportunity. Basically what you all want to do is to kick the user after he/she has worked for an amount of time. From my point of view this differs from the concept of session. Those define a timeout of inactivity time - not a maximum working time (There is a great difference in limiting the time a user has to max. 30 minutes or set the maximum inactivity time to 30 minutes). If this time is reached the session object is removed from the server. Why? In order to free up resources on the server side. In your client timer solutions how to you ensure that the session object gets removed from the server? In order for your solution to work properly you need to start your server with an infinite session timeout and this can very easily be a problem if your session-object-free-up mechanism fails.

Format Double to String
Hello Everybody, Our application puts out a lot of double values. Unfortunately it is not ok to output the double value using the exponent - for example: 12E-7 we want the the whole number - for example 0.00012 I am really stuck, as GWT does not support the DecimalNumberFormat and I do not get it to work using the NumberFormat class. Any ideas? Help? Thanks in Advance for your help! Greetings Stefan -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

MenuBar with Icons
Hello Everybody, Can anyone be so kind and point out some documentation for creating MenuBars with Icons. I already have the ResourceBundle (MenuBar.MenuBarImages) and I create the menubar using the follwing constructor: new MenuBar(Resource resource). Unfortunately no icons are displayed. Furthermore I could not find any examples about this on google or any documentation at all. Very sad... :( Perhaps I could proceed if a knew what the method: AbstractImagePrototype menuBarSubMenuIcon() does? Do the image resources and the menuItems have special names so that the appropriate icons can be found? As you can see help is really appreciated! ;) Thanks in Advance for your help!

Register Labels to listen for combo box events
Hello Everybody! I have a more or less complex GWT page, consisting of comboxboxes, labels, buttons... (yes, it is the specification for a calculation! ;) Now I need a good approach/solution for the following problem: As soon as I change the value on one combobox I need the text of some labels to change. It can not be done manually from the combobox (use the onValueChange event and call label1.setText, label2.setText, ...) as the combobox does not known which labels to change. Only the label knows which combo box it should listen to. (Reason: Number of comboboxes is created dynamically) So I was thinking if there is a way to tell specific labels (during their creation) to listen for onValueChange events on a specific combobox. If the comboxbox changes its value, and an event is fired, all labels will be called an can change their value. Is this possible? (How!? ;) Anyone ever had the same problem?

Re: Session Timeout Popup
Thanks for your quick reply. I am just wondering if there is no easier way to do this.

Re: NumberFormat
No one?
On Mar 25, 11:32 am, StrongSteve swe.sta...@gmail.com wrote:
Hello,
I experience the following - from my point of view unexplainable -
behaviour when using the GWT NumberFormat
(com.google.gwt.i18n.client.NumberFormat). I am using GWT 2.0.3,
Eclipse Ganymed and IE8/FF3.6.
Within my client package I have a static helper class which contains
the following method:
code
public class Utils {
...
public static final NumberFormat DOUBLE2_FORMAT =
NumberFormat.getFormat(##.00);
...
public String formatDouble2(double d) {
return DOUBLE2_FORMAT.format(d);
}
...
}
/code
Using the code above I get a javascript error when using the
formatDouble2 method. Compiling the GWT code in a detailed way and
the javascript error message is something like
com...i18n.client.positivePrefix is null or not an object. The GUI
gets stuck and the application is no longer usable.
So how did I solve it?
During debug instrumentalization I found two ways. Unfortunately I can
not explain either of them - so I was hoping someone can explain me
why it works! ;)
Adding a Window.alert(...) into the formatDouble2 and everything works
fine. Why!?
code
public class Utils {
...
public static final NumberFormat DOUBLE2_FORMAT =
NumberFormat.getFormat(##.00);
...
public String formatDouble2(double d) {
Window.alert(Utils: inside formatDouble2 d= +d);
return DOUBLE2_FORMAT.format(d);
}
...
}
/code
The solution I am currently using is to only use pattern itself as a
static member and create the NumerFormat within the method. This works
too.
code
public class Utils {
...
public static final String DOUBLE2_FORMAT_PATTERN = ##.00;
...
public String formatDouble2(double d) {
return NumberFormat.getFormat(DOUBLE2_FORMAT_PATTERN).format(d);
}
...
}
/code
BTW, changing the public static to private static did not work either.
Thanks in Advance for your help!
