Re: VerticalPanel insert and index
If anyone else ever wonder about this issue I looked in the source code and the index range is actually set using the getWidgetCount() which I think is wrong but nevermind. As a workaround I'm using another grid with 1 column and k rows for each column so I can have an uneven grid On 25 נובמבר, 11:27, Ittai wrote: > Hi, > I tested and saw that when the verticalPanel is created it will > receive the index values of 0 and 1. and if you add by panel.add > (widget) > a label then you will be able to use 0,1,2 > but still I have no way to manipulate the index myself > Please has anyone any idea? > > On 24 נובמבר, 18:38,Ittai wrote: > > > > > Hello all, > > I have an array of strings which I divide unevenly between different > > columns of a grid (by some unrelated logic) and I need the string in > > the i place of the array to be inserted to the i place of the column. > > My grid holds one row and 6 columns and in each column I have a > > VerticalPanel which acts as my column, mainly because the columns are > > in different sizes and can change. > > What i wanted to do is something like this: > > > for (int i=0;i > Label labelWidget = new Label(array[i]); > > getVerticalPanelColumn().insert(labelWidget,i); //where > > getVerticalPanelColumn() is my method > > } > > > Now I noticed that the API stated that IndexOutOfBounds will be thrown > > if the index passed to insert is out of range but the problem is that > > I couldn't, for the life of me, find any way to set the range'/size/ > > capacity of the verticalPanel or to query it (and I don't mean > > widgetCount() I mean the index to which I can relate). > > So basically as a horibble workaround (which I won't use) I think I > > can add "i" null widgets to the VerticalPanel thus I believe I will > > increment the index and do my iteration but this hack is irrelevant > > for me due to the "cost" of all those null widgets addition to all my > > columns. > > Basically I would like the insert to just insert the widget at the > > closest point to i that is if i==5 and the panel holds only widget > > whose index is 1 4 7 then the insert should insert the widget between > > 4 and 7 if i==10 it should just insert it in the end and remeber its > > index is 10. > > > Has anyone encountered this? > > Isn't this some sort of bug that you have no way to set or query an > > object about the index range but you can pass it an index variable? > > > Thanks a million for any help > >Ittai-הסתר טקסט מצוטט- > > -הראה טקסט מצוטט- -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: Should we use maven or not for a project?
I think there is an Ant integration for Maven, so it should be possible to reuse existing Ant builds. But I'm not sure how well it works. So the reasons, why Maven is easy for our GWT project is simple. We do Java development and all our GWT modules are build as plain Java projects, as JARs (containing a file called xxx.gwt.xml and the source code), that's it. So our whole Maven stuff works completely as pure Java stuff like in any other Java project to. The only point where GWT integration comes in, is that in our web app's POM file, there is the GWT-Maven plugin configured to compile a specified GWT module (included in a JAR, which is a provided-scoped dependency) as JavaScript to the web-app directory (so it's included in the WAR). We don't use GWT unit tests, instead our code is as independent from GWT as possible (e. g. MVP Pattern) and normal unit tests work well. We don't use i18n Message interface generation, since it doesn't increase productivity, we're using an IDE. We don't run anything from Maven, we're launching our development environments from Eclipse (GWT plugin). So at least, Maven has two roles in our project. The first is doing the build, running the unit tests automatically, but all on top of typical Java projects. The second is the project configuration. We're using m2eclipse plugin to enable Eclipse configuration by Maven. Since we're doing no special stuff, m2eclipse configures our Maven projects as simple Java projects or web projects. There is one project containing our 'main' GWT module, this has to be made a GWT project manually (GWT Eclipse plugin, just do it once) to launch the hosted browser from the IDE. This works well, except sometimes m2eclipse changes the order of the libraries in Eclipse classpath and then hosted browser crashes, but it can be fixed easily. I wouldn't do it another way, if I had chosen Ant or Gradle or anything else. The rules are clear, use the power of your IDE for development (it's not the work a build tool is made for) and keep your project a Java project. The second point is important. You can do standard Java development with JUnit or TestNG, standard packaging and build tool configuration and that's exactly, what I recommend. Reduce GWT to the things it's really needed for in your project. Regards Jan Ehrhardt On Sat, Nov 28, 2009 at 11:47 PM, jbdhl wrote: > Thanks for all your insightful comments!

LayoutPanel support in RC2
Has anybody managed to get the GWT layout panels to work in RC2? In
the javadoc for SplitLayoutPanel has the following example that does
not work for me, it just shows a blank page.
SplitLayoutPanel p = new SplitLayoutPanel();
p.addWest(new HTML("navigation"), 128);
p.addNorth(new HTML("list"), 384);
p.add(new HTML("details"));
RootLayoutPanel rp = RootLayoutPanel.get();
rp.add(p);
Is there some extra css I need to use? My host html page looks like
this

Re: ERROR: GWT.create() is only usable in client code! It cannot be called, for example, from server code.
This is because you are using XMLParser in server side. Otherwise you should
put that code under the client package.

Re: Should we use maven or not for a project?
I would suggest using ant, it provides more flexibility. I have been on a GWT project with Maven and Ant, and Ant hit a lot less roadbumps. Also if you want to build GWT itself it uses Ant.

ERROR: GWT.create() is only usable in client code! It cannot be called, for example, from server code.
I have the following code on my server
public ArrayList getAMIs()
{
ArrayList amis = new ArrayList();
int n;
AMI ami = new AMI();
GetResources amiResourceXML = new GetResources();
try
{
Document amiDom =
XMLParser.parse(amiResourceXML.getAmi());
Element root = amiDom.getDocumentElement();
XMLParser.removeWhitespace(root);
...
}
catch
{ ..}
return "some value to client"
}
Why do I receive this error below?

Re: lacking an interface with "setEnabled" method
I ended up writing a bunch of small *Ext classes (TextBoxExt, etc.) that implement some interfaces of my creation, HasEnablement (clunky naming, I know) being one of them. I second the request that such an interface be added to GWT. On Nov 23, 9:37 am, Michel Daviot wrote: > Hi, > > I think an interface defining the setEnabled method is lacking.

Re: HMVP design pattern?
> MVP structure with item duplication prevented by checking > proposed additions to a shopping cart against all the others via the > event bus. This is basically what I've done in my first GWT hierarchical MVP app. One of its functions is to collect two password recovery question choices, one from each of two listboxes The parent presenter adds two questionbox presenters which communicate selection choices via the eventbus. User selections for questions, answers, password updates, etc. bubble up this way to a level where it can be determined whether or not the update button can be enabled. At first, I thought this might be too fine-grained, but it's worked out well to separate out the logic this way. The problem I quickly ran into with MVP was that the ratio of boilerplate to interesting code was very bad. So, I built a quick and dirty codegen using StringTemplate that reads an XML description of the presenters/UI (no 2.0 yet) and generates a display impl, a presenter interface, a presenter impl abstract base class, associated events, and RPC plumbing (and validation bindings, etc, etc.) So far, so goodI feel like I'm writing mostly unique code without too many redundantly expressed ideas. One additional problem was that some of the presenter logic got very complicated very quickly. I ended up drawing a state machine and implementing it with SMC (http:// smc.sourceforge.net/). The presenter fires state machine actions which in return fire presenter methods to modify the display and other client-side state. With minor modification, the generated SMC code plays nicely in client-side GWT. I'm now interested in how hierarchical state machines could be used to model GWT apps in a more integrated way. How much of client side behavior can be declared without boxing a developer into a too-rigid framework? Would the resulting JavaScript be small enough? Has anyone else experimented with these sorts of things? Anyone interested enough in what I've done for me to attempt to open source it (it's corp-owned right now)?

Re: dynamic Messages/ImageBundle possible?
Thanks a lot,
that's indeed what i needed. It took me sometime to realize what the
requirement to put Messages.properties files in "classpath root"
really means. Is there a possibility to have Messages.properties
reside within the same package where the code using it (maybe though
an interface), since it makes it somewhat uncomfortable the way it
works now, more even so when you have several gwt modules in a single
project that should use difference bundles.
thanks

Youtube video not displayed
Hello all,
I have a problem when trying to display youtube videos in my gwt
application. I have the youtube video url in my data base.
Then i try to display the player by doing that:
String htmlTag = getEmbedTag(linkPublication.getLinkURL());
HTML html = new HTML();
html.setHTML(htmlTag);
this.extraArea.add(html);
private String getEmbedTag(String linkURL) {
return "";
}
The embed tag is attached to the page but I cannot see the video.
Any ideas?

Re: GWT 2.0.0rc2 ::: Unknown argument: -portHosted
Hi All
I should really know by now, that the Internet is a wonderful, wonderful thing!
On the page I quoted:
http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC
there is a comment, currently second from bottom, on November 23rd by
"a.revolution.ultra.blue", which states, in response to another
comment that has the same problem the people in this tread are having:
--BEGIN---
YES! You CANNOT use the google g-icon "web app run menu", you need a
plain jane java application runner, with main class
com.google.gwt.dev.DevMode??
Make sure you have the usual program arguments for a gwt project; mine
are: -port -startupUrl / ai.yx.xSeed
I have / set to a welcome servlet in web.xml, and my gwt project is ai.yx.xSeed
If you want to use appengine, you will also need to add the program
arguments and vm arguments I mentioned in the post above. ALSO, if you
do NOT use appengine, leave the working directory at default. If you
DO use appengine, add /war to whatever your default directory is... My
project xBook uses ${workspace_loc:xBook}/war
If you absolutely can't get it to go, just download ms2 from the
deprecated dl page, and you can go ahead and use the old google-plugin
launch configuration.
--ENG--
So, I am now a little further. I have a Java Application Run
Configuration that uses com.google.gwt.dev.DevMode as the Main class
and has the arguments: -port Gwt2RC2 (my project is called
Gwt2RC2).
However, i still have a problem when I run it:
[ERROR] Unable to find 'Gwt2RC2.gwt.xml' on your classpath; could be a
typo, or maybe you forgot to include a classpath entry for source?
I've tried fiddling with the classpath and source settings of the Run
Configuration, but so far nothing's worked. Does anyone know what I'm
doing wrong?

Re: GWT 2.0.0rc2 ::: Unknown argument: -portHosted
Hi I've just done a completely fresh Eclipse and GWT 2.0 RC2 install including the new plugin: 1.Extracted eclipse-java-galileo-SR1-win32.zip to C:\Program Files (x86). 2.Ran Eclipse, set up a new workspace workspace at C:\Users\Paul\Documents\Sandbox\EclipseWorkspace and selected “Use this as the default and do not ask again.” 3.Then installed Eclipse's Web Standard Tools (WST) - Help->Install new software. - Manually added the update url as none was present: http://download.eclipse.org/releases/galileo/ - Then Web, XML, and Java EE Development -> Eclipse Web Developer Tools - Restarted Eclipse and then closed it. 4.Then copied gpe-e35-1.2rc1.zip\eclipse\features to C:\Program Files (x86)\eclipse. 5.Then copied gpe-e35-1.2rc1.zip\eclipse\plugins to C:\Program Files (x86)\eclipse\plugins 6.Then copied the contents of gwt-2.0.0-rc2.zip to gpe-e35-1.2rc1.zip\eclipse\plugins 7.Started Eclipse again and used the plugin to create a new project. - Started the wizard. - Configured the GWT SDK as C:\Program Files (x86)\eclipse\plugins\gwt-2.0.0-rc2 - Unticked “Use Google App Engine” - Entered project name etc and clicked finish. 8.Then opened the “Web Application” Run Configuration for the project and ticked “Automatically select unused port” and clicked Run. And I get the same error: Unknown argument: -portHosted Google Web Toolkit 2.0.0-rc2 DevMode [-noserver] [-port port-number | "auto"] [-whitelist whitelist-string] [-blacklist blacklist-string] [-logdir directory] [-logLevel level] [-gen dir] [-codeServerPort port-number | "auto"] [-server servletContainerLauncher] [-startupUrl url] [-war dir] [-extra dir] [-workDir dir] module[s] where -noserverPrevents the embedded web server from running -portSpecifies the TCP port for the embedded web server (defaults to ) -whitelist Allows the user to browse URLs that match the specified regexes (comma or space separated) -blacklist Prevents the user browsing URLs that match the specified regexes (comma or space separated) -logdir Logs to a file in the given directory, as well as graphically -logLevelThe level of logging detail: ERROR, WARN, INFO, TRACE, DEBUG, SPAM, or ALL -gen Debugging: causes normally-transient generated types to be saved in the specified directory -codeServerPort Specifies the TCP port for the code server (defaults to 9997) -server Specify a different embedded web server to run (must implement ServletContainerLauncher) -startupUrl Automatically launches the specified URL -war The directory into which deployable output files will be written (defaults to 'war') -extra The directory into which extra files, not intended for deployment, will be written -workDir The compiler's working directory for internal use (must be writeable; defaults to a system temp dir) and module[s]Specifies the name(s) of the module(s) to host I assume I must be doing something wrong in my install? Having to manually copy the SDK took me rather by surprise. I guess its kind of implicit here, http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC, but an explicit instruction would have been helpful. I'm running Vista Business if that makes any difference? -- Thanks Paul Paul Grenyer e: paul.gren...@gmail.com b: paulgrenyer.blogspot.com -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT1.7 + Spring3 intégration
I don't know, how your application is structured, but why don't you use
Spring 3 with REST and JSON?
Spring 3 comes with a cupel of nice features to create RESTful APIs on top
of Spring Controllers. This fits much better into the Spring world, than GWT
RPC could ever do.
On the other hand, GWT + JavaScript Overlays makes the usage of RESTful API
with JSON very smart to GWT apps.
We'd the same idea for the Grails GWT plugin, since Grails comes with REST
build in and GWT-RPC never felt native.
For me it would definitively be the preferred way in a Spring world.

Re: Should we use maven or not for a project?
Yes, Maven can be complex, but if your project has a clear structure, it can be very powerful. Another option, I haven't tried yet, could be Gradle. It is a build tool, that uses Groovy for writing build scripts. The benefit is, that it's based on Ant and Ivy, so it allows you to use all the Ant stuff around.
