Hi,

I would like to use ClientBundle and ImageResource.
But I would like to supply different images (under the same name) by
browser.

Does anyone have an idea how this could be achieved easily?

 I need only date value in exported data file.

 Please suggest us that how I remove time (00:00:00) value and also how I

 Below is snippet of my code.

Re: Dev plugin for firefox 3.7

I'm developing a large WebGL application which is currently only

sadly, no :-) .


I really, really want to be able to debug GWT in Firefox, so if 
necessary I'd be prepared to help with testing/building.

UiBinder and child widgets

2010-06-15 Thread Joost Bloemsma

Hi,

I've made a very simple GroupBox widget which works fine. I can add it
in java to a panel, set caption and add widgets. But now I want to add
it in a UiBinder template file.
To enable it to contain HTML, I had to implement the HasHTML
interface. Now the following works fine:

g:HTMLPanel
b:GroupBox caption=hello
Hello World
/b:GroupBox
/g:HTMLPanel

Next step; I want to be able to add child widgets from within my
template, eg:

g:HTMLPanel
b:GroupBox caption=buttons
g:Button ui:field=btnShowShow/g:Buttonbr/
g:Button ui:field=btnClearClear/g:Button
/b:GroupBox
/g:HTMLPanel

Even though my GroupBox class extends the AbsolutePanel class, which
implements the HasWidgets interface, it fails with the following
error:
Found widget g:Button ui:field='btnShow' in an HTML context

Has anybody an idea how I can add child widgets in my UiPanel
template? How do I have to implement my container widget?

Thanks, Joost

Re: 1 layout - 3 browsers - 3 results?

Hi!

I guess the point is that you used a FlowPanel which does not stretch
its children. I found out that this is also true for AbsolutePanel.

Thanks!

BTW: I wonder why you use this construct:

 int parentH = dock.getWidgetContainerElement(this).getOffsetHeight();

Why not simply call:

doc.getParent ().gettOffsetHeight(); ?

The latter code would also be usable for parents that are no
DockLayoutgPanel. Is there a special reason?

  But let me come back to your code for centering the chess board: The

  However, doing the same with a form was not possible for me since I am
  building on top of your code template. The reason is that I don't know
  the size of my form. I put all the widgets together in a panel (I
  tried every type) and add this panel to my DockLayoutPanel. Then it's
  immediately stretched, so that I cannot retrieve its natural size.
  But exactly this size is needed to do the centering as you did in your
  code.

  How would you do this? Can you help me again?

  Thank you

Re: Layout UI Objects and GWT Themes

Hi,

Old widgets uses a 9-box (a table with 3x3 entry).

CSS3 allows to similate a 9 box with border images.
However, images inccrease download time.

And CSS3 allows to apply rounded corner (-o/-moz/-webkit/-border-
radius)


Without a modern browser you still have to take 9 box.

SuggestBox MultiWordSuggestOracle autocomplete can't create suggestion/display pairs except for default

2010-06-15 Thread Marc Hacker

I have a GWT autocomplete new SuggestBox((new
MultiWordSuggestOracle());

For the default suggestions which appears before the user types any
prefix, there is a nice method

MultiWordSuggestOracle.setDefaultSuggestions(CollectionSuggestion
suggestionList)

so I can pass a nice list of a Suggestion's which are displayed as
html (for example I can create FaceBook style autosuggest with two
lines displayed in each item but with a simple replacement text by
simply implementing the Suggestion interface).

But for suggestions that appear once the user starts typing, the only
method seems to be

 add(String suggestion)

where I cannot control how it is displayed at all.

Any ideas how I can create a Suggestion with separate (html) display
and (simple text) replacement  values for the auto-complete as I can
for the default?

Thx

Marc

Does AdSense work with GWT? If so, How?

I'm looking at using this framework for a new project, but I need to

1 - Does AdSense work with GWT?

2 - If so, how?  I see a whole bunch of hacks that 'might' work, but I
need something more stable than that.

This is really a deal breaker for us...if AdSense does not work with
GWT, then we can't use GWT.

DockLayoutPanel inside a ScrollPanel

Hi,

I have a layout defined by:
- ...
  - ScrollPanel
- DockLayoutPanel
  - north
  - west
  - center
  - east

The problem is that the dock layout panel is cut off from the window;
the scroll bars don't appear. I can force the scroll bars to appear by
setting the height of both panels to some pixel, but this is obviously
not a useful solution.

Any hints?

Re: UiBinder and child widgets

2010-06-15 Thread Joost Bloemsma

Okay, fixed my problem already ;-)
First of all, it seemes that you cannot implement both the HasWidgets
and HasHTML interface. Well, you can, but the UiBinder will only
accept the first one. This means that if you implement HasWidgets,
HasHTML, you can only add child widgets. If you implement HasHTML,
HasWidgets, you can only add HTML. This is quite easy to work around.
Simply just implement HasWidgets and add all HTML using an HTMLPanel.

Then the tricky part:
My GroupBox is subclassed from AbsolutePanel, which already implements
the HasWidgets interface. It seems though, that I have to declare that
interface again in my GroupBox class, else UiBinder won't recognize
it!
(Is this a bug?)

So the solution was simple: add the HasWidgets interface to the
GroupBox class declaration and we're done!

g:HTMLPanel
b:GroupBox caption=hello
Hello World
/b:GroupBox
b:GroupBox caption=buttons
g:HTMLPanel
g:Button ui:field=btnShowShow/g:Buttonbr/
g:Button ui:field=btnClearClear/g:Button
/g:HTMLPanel
/b:GroupBox
/g:HTMLPanel

Works like a charm now!

 Next step; I want to be able to add child widgets from within my

         g:Button ui:field=btnShowShow/g:Buttonbr/
         g:Button ui:field=btnClearClear/g:Button
     /b:GroupBox
 /g:HTMLPanel

 Even though my GroupBox class extends the AbsolutePanel class, which
 implements the HasWidgets interface, it fails with the following
 error:
 Found widget g:Button ui:field='btnShow' in an HTML context

 Has anybody an idea how I can add child widgets in my UiPanel
 template? How do I have to implement my container widget?

Re: UiBinder and child widgets

2010-06-15 Thread Joost Bloemsma

Okay, fixed my problem already ;-)
First of all, it seemes that you cannot implement both the HasWidgets
and HasHTML interface. Well, you can, but the UiBinder will only
accept the first one. This means that if you implement HasWidgets,
HasHTML, you can only add child widgets. If you implement HasHTML,
HasWidgets, you can only add HTML. This is quite easy to work around.
Simply just implement HasWidgets and add all HTML using an HTMLPanel.

Then the tricky part:
My GroupBox is subclassed from AbsolutePanel, which already implements
the HasWidgets interface. It seems though, that I have to declare that
interface again in my GroupBox class, else UiBinder won't recognize
it!
(Is this a bug?)

So the solution was simple: add the HasWidgets interface to the
GroupBox class declaration and we're done!

g:HTMLPanel
b:GroupBox caption=hello
Hello World
/b:GroupBox
b:GroupBox caption=buttons
g:HTMLPanel
g:Button ui:field=btnShowShow/g:Buttonbr/
g:Button ui:field=btnClearClear/g:Button
/g:HTMLPanel
/b:GroupBox
/g:HTMLPanel

Works like a charm now!

Re: using gwt for games - svg, canvas or something else?

Hi,

the gwt-canvas demo impressed me:
http://stud-in.fh-swf.de/Oliver.Zoran/gwt-canvas/

But I cannot see how this relates to standard GWT programming. It
seems that there is a separate library that has to be used. How can I
be sure that my code will still run with the standard GWT SDK in the
future? Are'nt there methods for using canvas with plain GWT?

 I've been wondering about the same thing. SVG and canvas aren't
 supported very well yet. The same goes for WebGL. But I'd love to use
 GWT to create games as the end result would be highly portable *and*
 it would not require the user to install any plugins.

 I've been thinking of trying a Java game engine like JMonkeyEngine or
 JGame but such engines often rely on OpenGL or DirectX (for hardware
 acceleration) and I'm not sure how that would translate into the
 JavaScript world. I haven't found any pure JavaScript game engines
 that looked really usable. The Aves Engine looks very promising but
 it's still alpha.

 I too would love to hear other people's opinions on this.

Failure creating a timer in ServerImplementation

2010-06-15 Thread uwi_u

Hi!

I'm writing an application which starts a new timer for each user
logging in.
I'm storing the timers in a HashMap for easy access. A KeepAlive from
Client will get the timer out of the Hashmap and reset it. But when
executing Timer t = new Timer(){}, the method crashes. Can
somebody tell me why?

Heres the Code of my ServerImplementation:

if (setConnection(server, DBschemeName, user, passwd) == false) return
0;
else {
connectedUsers.put(user, passwd);
logWarn(Baue Timer);
Timer t = new Timer(){
   public void run() {
   logoutUser(user);
   logWarn(User +user+ logged out due to Timeout!);
}
};
t.schedule(logoutTime);
userLogoutTimers.put(user, t);
return 1;

Re: AOP Framework

2010-06-15 Thread fmod

I did not thought on having a feature like that. Can be great if you
can provide some case study for it.

IMHO doing something similar to gin, should not be that difficult. At
least when it comes to provide a factory for the intercepted
classes.

What it struggles me a bit more, is how the methods interception are
defined. Since you don't want to modify the classes, I guess you less
want to annotated their methods. Maybe a good approach is using
Matchers as GIN does.

I believe this feature is more in the scope of GIN. In fact they have
plans to introduce AOP some day.
http://code.google.com/p/google-gin/issues/detail?id=38

I'm developing this 'framework' together with a real application. So,
the features are a bit driven for the needs of my application. But an
integration with GIN is a must someday I will need to face.

On Jun 15, 4:56 am, Carl Pritchett bogusggem...@gmail.com wrote:
 IMHO it would be great if you didn't have to add an interface to the
 Interceptable classes, but instead created a binding class (something

 target classes.

 Of course easier said than done.



  The code looks like:

  {{{
  public class MyClass implements Interceptable {
    @Intercept(LoggerInterceptor.class)
    public int add(int a, int b) {
    }

  }
  }}}

Re: where to define domain objects

2010-06-15 Thread Denis

The domain object I mentioned needs some further clarification:
It's a serializable Data Transfer Object/Bean/POJO that will be
transferred across all layers: presentation, business, and
persistence.

With this in mind, I put the domain package under \client following
the approach described in the book of 'Pro Web 2.0 Application
Development with GWT'

On Jun 13, 11:08 am, Stefan Bachert stefanbach...@yahoo.de wrote:
 HiDenis,

 It is absolutely clear where domain object are NOT located, in client
 and shared. Domain objects have nothing to do in GUI or client

 for a very simple project I would put it under server.
 But in general I would put domain objects into a separate project.
 The reason is, in general there is more than one application possible
 dealing the same domain objects.

 In general you have the following kind of objects on the server side
 which may build an own layer and thatfore projects.

 Session objects (state of your gui, application dependant, may be
 persistent)

 Application objects (application dependant, persistant)

 Domain objects (application independant, persistant)

GWT 2.1 / Google I/O 2010 - GWT's UI overhaul

2010-06-15 Thread magnum

in response to:

http://www.youtube.com/watch?v=g2XclEOJdIcplaynext_from=TLvideos=3iOGbt6Y2as


great work guys!! The GWT is becoming what I hoped it to be back in
2007, a lot of nice cleanups. Actually the code splitting, multiple
entry points on one page, and integration with existing javascripts
were our biggest concearns and 80% of them ahave been resolved over
the years.

Still most of the new functionalities suffer from the java-syndrome
- too many abstraction layers and plainly frustrating boilerplate.

Now I want a graphic UI editor and crawlable gwt code.
With UI binder we've done a full circle ... from JSP / Velocity to
Swing/Programatic layouts to another form of templates. I want my
templates to be renderable / editable by my web designer. This is a
must!

Also the crawlability is a must, once this is done, PHP can finally
rest in peace. Until then, wordpress is the best tool if you want your
page to be findable. I don't care how great service you provide,
people need to know your page exists before they use it.

I tried to copy the sample html that launches the GWT app in the project
outside it and play a bit with it, but I didn't get far to be honest.

Any help will be appreciated ^^

That's the code that DOESN'T work

Re: GWT 2.1 / Google I/O 2010 - GWT's UI overhaul

2010-06-15 Thread Katharina Probst

Thank you, glad we're addressing your concerns.

As for crawlability, Google has recently introduced a new scheme to make
Ajax (including GWT) apps crawlable. It is documented here:
code.google.com/web/ajaxcrawling.

Several users have used this scheme successfully in their apps. For GWT
apps, HtmlUnit is a good choice to create an HTML snapshot.

Thanks!

great work guys!! The GWT is becoming what I hoped it to be back in
2007, a lot of nice cleanups. Actually the code splitting, multiple
entry points on one page, and integration with existing javascripts
were our biggest concearns and 80% of them ahave been resolved over
the years.

Still most of the new functionalities suffer from the java-syndrome
- too many abstraction layers and plainly frustrating boilerplate.

Now I want a graphic UI editor and crawlable gwt code.
With UI binder we've done a full circle ... from JSP / Velocity to
Swing/Programatic layouts to another form of templates. I want my
templates to be renderable / editable by my web designer. This is a
must!

Also the crawlability is a must, once this is done, PHP can finally
rest in peace. Until then, wordpress is the best tool if you want your
page to be findable. I don't care how great service you provide,
people need to know your page exists before they use it.

 The intermediate panel would be sized when added to the

Re: GWT and Spring - with Spring Web MVC or without it?

2010-06-15 Thread Richard Allen

For operations like file upload which cannot be done with Ajax, GWT
provides no server-side facilities. With Spring MVC, you can easily
wire up a Spring Controller that handles the file upload request that
a GWT client submits to.

See:
http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/mvc.html#mvc-multipart

Yes, Spring MVC is a page-based framework with both server-side and
client-side facilities, and GWT is a component-based mostly client-
side only framework that was designed for web applications that
execute in a single page, such as Gmail, Google Maps, and Google Wave.
However, even an app like Gmail has a login page that is separate from
the actual application which submits a form post, then redirects the
browser to a separate page that loads the application. Spring MVC is
well suited for serving pages like that login page and handling the
form post.

Additionally, there is great benefit derived from using Spring Core
for dependency injection and AOP of your server-side code. All serious
Java web applications that I have worked on have significantly more
server-side code than client-side code.

Hi,

Spring MVC does not fit to GWT at all.

GWT considers the browser to be a thin/rich client, and the server to

Spring MVC considers the browser to be an ultra thin client (something

where presentation, business logic and persistence live.
Spring MVC is an artefact of the pre-AJAX-era.

Use GWT for real application (RIA) and use Spring MVC for hyperlinked
documents.

In a complex website you may switch between real applications and
hyperlinked documents, so you will find both in one site.
But it makes NO sense to drive GWT with Spring MVC.

Hi all...

I am new to GWT - had some contact with it earlier but not enough to

My task is to investigate this technology and pair it with Spring

done, but what is bothering me is I can't decide which approach to
choose. For example, I've seen one using Spring's MVC (like this
one:http://technophiliac.wordpress.com/2008/08/24/giving-gwt-a-spring-in-...),

(e.g.http://code.google.com/p/gwt-spring-starter-app/)

I am afraid to miss something important by choosing one of these
approaches and possibly lose some of Web MVC functionalities that
might be needed later or end up in dead end street using it.

I would be grateful if anyone explained me what are the pros and cons
of these approaches from practical point of view - is there a need for
DispatcherServlet and Controllers while having GWT and its RPC
mechanism.

Thanks in advance.

Build file Corresponding to GWT Compilation From Eclipse

2010-06-15 Thread Daniel Simons

I'm curious about what occurs with regard to Ant when eclipse compiles my
gwt project.  I'm assuming there is a build.xml file that is generated and
ant runs some javac process declared within the build.xml to compile the
java into javascript.  If this is correct, is it possible to view the
contents of that file?  If not correct, could someone explain further what
is actually going on?

Re: DockLayoutPanel inside a ScrollPanel

You need to set the docklayoutpanel's height and width.

 Hi,

 I have a layout defined by:
 - ...
  - ScrollPanel
- DockLayoutPanel
  - north
  - west

  - east

 The problem is that the dock layout panel is cut off from the window;
 the scroll bars don't appear. I can force the scroll bars to appear by
 setting the height of both panels to some pixel, but this is obviously
 not a useful solution.

 Any hints?

how do you place applet in gwt? You know that applet must be placed for

Re: DockLayoutPanel inside a ScrollPanel

If i'm not mistaken you may be running into essentially the same kind
of dilemma I've had to deal with. My site doesn't use a DocLayoutPanel
cuz I made this part of my site long before layout panels existed in
GWT, but I think some of my divs are the same thing as layout panels.
I use css styling; position:absolute along with specific top, right,
bottom, left coords to make a panel that takes up all the the
remaining width and height left in the page. The internal divs are
absolute and set with width and height at 100% and that seems to be
enough to create scroll bars if the contents are larger than the
container. I do actually have the second inner div with overflow set
to auto, but I'm playing with the CSS right now and having that (the
overflow css) NOT set doesn't change the scrollbar or anything. I
guess I don't need it...

So... is my assumption that LayoutPanels have position:absolute and
the four directions set to 0px (or whatever value) correct? If so,
maybe that panel can gain scrollbars by making inner panels have
position:absolute and height:100% as well?

I'm not entirely sure, though I'm sure I could figure it out if I
played with the css on your site. Or you can just use a DOM inspector
on my site at http://subtabs.skystrider.com and see how I accomplish
it.

hope that helps a little bit :)

Re: exchange image by browser

I personally prefer to keep logic in the application's language. I
like to keep CSS for just styling and keep all my logic in JS. Is
there a particular reason you can't just use JS to detect which
browser is running and then grab the right ImageResource for the job
(in this case you then need one ImageResource for each browser)? Of
course, you don't have to comply with my own standards and as such you
would need to use conditional css as was kindly mentioned by fmod.

 Hi Guys,

 from GWT which i am not able to solve.
 Now when user clicks on something(link/button etc) i add the token to
 History and my history callbacks get called.
 Now in history value change handler i do something like this

 1) FInd out what page need to be dispalyed(basically identify the
 panels etc).
 2) now each of my panel which can have history implementing
 hasHistory(my own) interface, which has function
 recoverPanelFromHistory.
 3) In this function, i check if i have client side data cahced for
 this panel, if yes then load it into panel and display it(basically
 add to main panel widget tree).
 4) But if no cache data found then go to server and get data.

 one such implementation
 @Override
         public boolean recoverPanelFromHistory(MapString, String
 historyTokens) {
                 String page = historyTokens.get(PAGE_PARAM);
                 boolean returnValue = false;

 mainPanel view of client
                                 mainContentPanel.add(userHomePanel); //and 
 adding the view
 according to history token value
                         }
                       else
                       {
                            //dont change the browser view and stay at
 current panel/view/page. This also means child panel can not be
 recovered and there must be some problem with history tokens provided.
                       }

                 }
                 if(profile.equalsIgnoreCase(page))
                 {
                         returnValue =
 prodilePanel.recoverPanelFromHistory(historyTokens); //and this
 function will calls its child panels if they support history
                         if(returnValue )
                         {
                                 mainContentPanel.clear(); //clearing the 
 mainPanel view of client
                                 mainContentPanel.add(profilePanel); //and 
 adding the view
 according to history token value
                         }
                       else
                       {
                            //dont change the browser view and stay at
 current panel/view/page. This also means child panel can not be
 recovered and there must be some problem with history tokens provided.
                       }

                 }
                 return returnValue;

         }

 So till now theoretically it sounds good and works good.

 Problem starts when lets say user lost his Internet connection or call
 fail at server because of any system level error..

 userHomePanel.recoverPanelFromHistory(historyTokens);

 This function does following things.
 1) get the data from cache for this panel
 2) if found call loadDataIntoPanel(data) function and load it into
 panel and return true.
 3)  else call the server to get data.
     Now server call is async and I need to return some value from
 userHomePanel.recoverPanelFromHistory(historyTokens);, so if i return
 true and call fails at server because of some network problem then
 ideally i dont want to switch to new view as per this history action
 but my function has already returned true and mainPanle has already
 changed the view to new panel.
 Now i dont want child panels to call parentPanel's method to tell them
 later that server call was success or failure so that main parent
 panel can decide whethere i should switch panels/view or not. If child
 need to know parent then my all panels will be too much dependent on
 each other and they will be too much crossed chain to each other.

 If you see gmail it uses such features. If you have loaded ur inbox
 and then you lost ur internet connection and then u click on any
 email. Then gmail doesnt take you to single mail viewer page and then
 tell oh u lost ur connection but it just keep you on inbox view and
 keep trying and after some time stop trying.

 How can i achieve such functionality.?
 Are there any existing libraries to do that or any particular design
 pattern is there?

 Thanks, in advance

Re: History and server call.

Well, I don't know about the event bus and I have yet to watch that
GWT best practices video (but I really should!) and I haven't done MVP
with GWT, BUT I'm super creative so here's what I would do with your
situation! :D

I would have an object that is rather more aware of the all
recoverPanelFromHistory async actions going on. This object would
store a copy of each other object that is performing the
recoverPanelFromHistory for a specific panel. (in other words a list
of objects that have the method(s) controlling all that async
goodness) The code inside recoverPanelFromHistory() that does the
async data retrieval from the server would talk back to this object,
which is the owner. It tells the Owner that it's finished getting
the data (even when it already had the data cached). Every time the
owner gets told that one of it's subjects finished getting data it
checks to see if that was the last subject to get it's data, and if
so it talks to the mainContentPanel and gets it to do it's view change
(clear and add). Inside the recoverPanelFromHistory code you can do
your repeatedly trying to obtain the data and even if you don't get
the data until a day later when the user finally reconnects your code
will be able to continue on no prob.

Did that make sense? It makes sense in my head, so if it doesn't make
perfect sense to you ask me to clarify things and I'll do my best!

You'll have to do some refactoring... the code inside
recoverPanelFromHistory() that does the depth search through all
children and fires recoverPanelFromHistory() on all children and their
children you'll want to still happen at the place where you currently
call recoverPanelFromHistory() from the top of the tree... BUT you'll
want to refactor the code that does the data cache check and then
calls the async-data-get out of that method. The depth search of all
children will add each child (aka subject) to the Owner object.
After the Owner knows about all of it's subjects it then loops through
and calls the recoverPanelFromHistory() code which does the data cache
check and asyn-data-get goodness. This way the owner doesn't think
it's done loading just cuz the first subject added has it's data
cached and immediately tells the owner before any other subjects have
been added. did that make sense?

btw, did I just invent an event bus?

cheers! ^_^

  Hi Guys,
  I have just implemented a multipage(basically multi url) website using
  History. It works great using history token. But i need something else
  from GWT which i am not able to solve.
  Now when user clicks on something(link/button etc) i add the token to
  History and my history callbacks get called.
  Now in history value change handler i do something like this

  1) FInd out what page need to be dispalyed(basically identify the
  panels etc).
  2) now each of my panel which can have history implementing
  hasHistory(my own) interface, which has function
  recoverPanelFromHistory.
  3) In this function, i check if i have client side data cahced for
  this panel, if yes then load it into panel and display it(basically
  add to main panel widget tree).
  4) But if no cache data found then go to server and get data.

  one such implementation
  @Override
          public boolean recoverPanelFromHistory(MapString, String
  historyTokens) {
                  String page = historyTokens.get(PAGE_PARAM);
                  boolean returnValue = false;
                  if(home.equalsIgnoreCase(page))
                  {
                          returnValue =
  userHomePanel.recoverPanelFromHistory(historyTokens); //and this
  function will calls its child panels if they support history
                          if(returnValue )
                          {
                                  mainContentPanel.clear(); //clearing the 
  mainPanel view of client
                                  mainContentPanel.add(userHomePanel); //and 
  adding the view
  according to history token value
                          }
                        else
                        {
                             //dont change the browser view and stay at
  current panel/view/page. This also means child panel can not be
  recovered and there must be some problem with history tokens provided.
                        }

                  }
                  if(profile.equalsIgnoreCase(page))
                  {
                          returnValue =
  prodilePanel.recoverPanelFromHistory(historyTokens); //and this
  function will calls its child panels if they support history
                          if(returnValue )
                          {

GWT Print

2010-06-15 Thread abhiram

Hi,

   I have been using the standard GWT printing methodology but I see
that the border lines and the grid lines get missed out in the print.
And the final printout only has the texts without any decorations. Can
someone suggest a nice GWT Print logic where the grids/scrollTables
appear with the borders and all ?

Thanks and Regards,
Abhiram
