Re: IntelliJ

[Alexander]

There is a demo from Jetbrains itself.
http://www.jetbrains.com/idea/features/gwt.html

I believe its enough to
understand how configure and run simple application in IDEA. What about
Maven integration - its not so hard just read about
http://mojo.codehaus.org/gwt-maven-plugin/

Debugger works out of the box. What problem do u have?

Don't do this when using GWT on Linux. This might be OK on Windows GWT, I
don't know. The hosted mode browser (FireFox) starts automaticatlly when you
start hosted mode.

 If you want to see how hosted mode debugging works on Linux, please try the
StockWatcher tutorial. Considering your skill level, running that tutorial
will be a no-brainer.

I don't see a reference to mozill-hosted-browser.conf. It may be that the

environment. I don't know.

At this point, I'd really recommend getting the StockWatcher tutorial
running in your Gentoo environment. That will give you a feeling of
accomplishment and will provide a solid foundation to understand how to port
your app to Linux from Windows.

DockLayoutPanel inside custom DecoratorPanel

[Will]

I am trying to create a custom DecoratorPanel that will work with
DockLayoutPanel as the child widget.  I tried a normal DecoratorPanel
and found that only Widgets in the North section of the
DockLayoutPanel actually render.  I used FireBug to determine that the
rest of the widgets are added to the DOM but are simply not rendering
on the screen.
I have also tried extending DecoratorPanel and implementing
RequiresResize, ProvidesResize but that didn't help.  When I
implemented the two interfaces my onResize was as follows:
public void onResize() {
if(getWidget() instanceof RequiresResize){
((RequiresResize)getWidget()).onResize();
}
}
The if logic executes (I verified with a System.out.println) however
the North section is still the only part that renders.  The
DecoratorPanel is added to the DOM with:
RootLayoutPanel.get().add(myPanel);
I am going to test with other LayoutPanels and see if this problem is
unique to DockLayoutPanel but I was curious if anyone else has
encountered this or has any suggestions for how I might resolve the
dilemma.

Re: Query on Google Web Toolkit (GWT)

[Chris Ramsdale]

Google has no intention of dropping support for GWT. Instead we will
continue to add features and functionality, much like we are doing with the
2.0 release of GWT. There's no reason to worry that the toolkit that you
have invested in will be deprecated.

Thanks,
Chris

Re: geocoder.LatLng don't work

[Eric Ayers]

geocoder.getLatLng() is an asynchronous method.  Your callbacks from
geocoder.getLatLng() will not going to have a chance to get called before
your method "getAddress()" returns.

Re: Development Mode Firefox 64bit Linux Issue

Im having the same problems, Im on debian so my Im technically running
iceweasel which is the free software version of firefox, It may be
complaining because it doesnt realise that iceweasel = firefox (Wave
does) or it may be, and that it does have the plugin installed or it
may be another issue. I really dont want to have to put non-free
software on my system like Chrome or Firefox to get GWT, do you know
of a work round, are the other chaps also on Debian?

Versions:
Iceweasel 3.0.6

Cache control for host page?

[shawnjohnson]

We are trying to resolve a caching issue we are having when we deploy
our GWT app.  Currently our servers don't really set any cache control
headers, not even expires.

I've only seen one opinion on this issue - they say to set cache-
control headers for the host page and nocache.js files to no-cache
(http://seewah.blogspot.com/2009/02/gwt-tips-2-nocachejs-getting-
cached-in.html).

Our GWT app really lives in one .html file - the host page, so if
someone were using the app when we deployed a new WAR their browser
wouldn't really know it.  To me it seems that we'd want to have
clients cache for at least a while?

Is there a best practice on this?

Query on Google Web Toolkit (GWT)

[Nilesh]

Hi Everyone,

I am working with one of the reputed software companies in India.
Recently I heard from one of my friends that google would stop
supporting GWT and start promoting Smart GWT. In our product
technology stack we have GWT and some other applications. if google
stops supporting GWT, what would the steps users would need to migrate
to Smart GWT?

can somebody answer my questions please?

Thanks

Embedding a gadget into a UIObject/Panel within GWT

[mmedvinsky]

Hi All,

I am having difficulty embedding gadget script tag with a UIObject in
GWT.  Has anyone done this?  It seems obvious at first but I can not
get it to wor for some reason.

What I would like to do is to use GWT as a layout container for
gadgets and that means adding a gadget to a container, such as
Panel.

For example: this gadget.

http://www.gmodules.com/ig/ifr?url=http://
www.webblossoms.com/gge.xml&synd=open&w=300&h=330&title=Web+Blossoms+Flowers&border=%23ff%7C3px%2C1px+solid+%2399&output=js\">

Renders fine in the browser if I include it as a script tag directly
into the page, however, it does not work from within GWT.

I tried setting innerHTML, creating manual elements, etc.  Nothing
works.

Thank you for you help

Re: mozilla-hosted-browser.conf and Gentoo Linux

[Mary-Anne Wolf]

I have been puzzling over your post for days.
Thank-you, but I still do not understand.

I am running GWT 1.5.3, which is <2.0 as you had guessed.

I am trying to run it within Eclipse using a .launch file.
I have an existing .launch file which is filled with Windows-specific
pointers to libraries,  I have created a second .launch file
which copies the first and substitutes in Linux equivalents.
It is this second file which I am trying to use on Gentoo Linux,
and which seems to be referencing mozilla-hosted-browser.conf.

When I open the .html file using a browser from within Eclipse,
which I assume must be Xulrunner, without running .launch,
I get a blank page, so I must assume that the .launch is
setting up some essential things the plain HTML is not.

This is what the .launch contains:












"/>


"/>


"/>




"/>


"/>








While I know that using GWTShell is no longer as common in later
versions of GWT, I think it is still recommended in 1.5.3.

Re: Has any one written new annotations for GWT Client side ?

[Jamie Gennis]

> Can you provide more information on the generator side and how can i
> accomplish this ?

It's not really well documented as far as I know, so the best place to get
information is by reading the source code of GWT and other libraries that
implement generators.  The basic idea is that in your .gwt.xml file you
specify an interface and a
Generatorclass.
 When the GWT compiler comes across a GWT.create(Foo.class) call
where Foo.class extends the interface you specified, it calls your Generator
class to create the implementation of that interface.  Your Generator class
can then generate the Java code for the implementation of the interface, and
an instance of that generated class will be returned by the GWT.create()
call.

This is how GWT's RPC interfaces work (see
RemoteService.gwt.xml
 and 
ServiceInterfaceProxyGenerator)
as well as many other GWT features (localization, UI binder, client
bundles).  You can also define a class that gets invoked at the GWT
compiler's link phase, but I don't think you'd need to do this just for
JSON marshaling.

Problem with JSON in Stockwatcher Sample

[TalkinJive]

Hi,

I'm new with GWT. I'm trying JSON with Stockwatcher application (with
servlet, overlay type and RequestBuilder). I've fixed the coma problem
in the JsonStockData servlet.

When I add or remove an item, method refreshWatchList call
JsonStockData servlet and everything is OK.
BUT when the timer call refreshWatchList, the servlet is not called
and the Response is always the same. So the prices don't change. No
exception is throwed !

I've found the same problem here :
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/33b64e07a9b13aba/362d25fe6524c07b?lnk=gst&q=JSON+bug#362d25fe6524c07b

Have I done an error ?
Is there a bug in Stockwatcher JSON tutorial ?
or a bug in GWT ?
Could you help me to fix that please ?

Re: Has any one written new annotations for GWT Client side ?

[keyboard_samurai]

Thanks for the reply ...

Can you provide more information on the generator side and how can i
accomplish this ?

I would definitely look into the lovely json rpc code. Any directions
on this would be greatly appreciated.

Thank you !

Cheers!

Re: Can anyone over here help me out in sending the email from gwt application

[Jeff Chimene]

Another technique is to create a mailto url (www.ietf.org/rfc/rfc2368.txt ).
Clicking such a link will launch the user's smtp client.

SplitLayoutPanel - Is there a way to set splitter position programmatically?

[shiang]

Hi all,

Do you know is there any workaround solutions to set the splitter
position programmatically of a SplitLayoutPanel?
(example: HoriozontalSplitPanel has the setPosition() method but
SplitLayoutPanel does not have).

Thank you,
Shiang

Re: Full GWT Website with MS SQL Server 2008

[Joe]

Well, You're right Sathya,

it is taking time, this is because the website contains lots of
tables,
horizontalpanel, htmlpanel, verticalpanel, etc ...

TextBoxes on the other hand do not take long, what takes long is
every dropdown, this is a customized widget built from scratch,
this too needs to be optimized.

The website has lot of images that load at startup, the website
doesn't take benefit yet of the powerful GWT technique, ImageBundle.

So you have lot of HTTP round trips. The listboxes, dropdowns,
are loading their data on startup upon creation, this too, can be
optimized
by loading data on demand, which means on click on the drop down
arrow.

as for the structure, I am working on a new layout which is div + css,
no tables.

As soon as things get finished, i'll be posting them!

Regards,

Joe

Re: listbox that contains widgets instead of just text..

[Joe]

Hi Jaimon,

There's a widget i have created long time ago, it's a listbox
functionality,
but where i have control on all css and styles and design of it. As
you know, the normal listbox of gwt depends on your browser look and
feel.

But the idea is simple: You need to have a textbox  with image(drop
down arrow).

Then, when you click on the image, a popup will appear below it.

The popup can contain a scrollpanel with a vertical panel.

The vertical panel can conatin any widget you want, a label, an
image,
a textbox, etc ...

Hope this will be helpful, let me know if you need any help.

Good luck,

Joe

Re: listbox that contains widgets instead of just text..

[Miroslav Genov]

Ops. My mistake, wrong answer of the right question :).
 Sorry about that. 

 So I think that you could define your own custom widget that is using
several existing widgets that are looking similar to that you wanna
build.
 You could extend the Composite widget and to combine other several
widgets together on it. Here is some example that would make the things
more clear (note that code is not compiled and may contains some
mistakes):

 public class MyListBox extends Composite {
   private Button showListButton = new Button("");
   private MyListBoxListItemsView items = new MyListBoxListItemsView();

   private HorizontalPanel container = new HorizontalPanel();
   
   public MyListBox(MyObject[] items) {
 initWidget(container);
 showListButton.setStyleName("myListBoxButton"); // set background
image and etc
 this.items.addAll(items);

 showListButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent e) {
 if (!items.showed()) {
   items.showList();
 } else {
   items.hideList(); // second button click have to hide list
items
 }

}
 }) 
 container.add(items);
 container.add(showListButton);
   }
 }
 and so on. 

 Hope this will help you to solve your issue. 

 Also You can look at the showcase example:
http://gwt.google.com/samples/Showcase/Showcase.html 
You could use Basic Popup for showing and hiding list items to the
user.(i.e in my example:showListButton could show and hide the Basic
Popup widget with rendered items) 

 Another option would be using of existing js widget and binding them
through JSNI, but I think that it's a little bit harder then using GWT's
widget library.
