I'm okay for blocking one part of the application or the whole for
global processing (login...). What I dislike is application blocking
me when I just ask for a little component to upgrade. Like if you have
a iGoogle page and click refresh on one widget block all widgets ;).

 When the user presses load / submit / ... on my app, I enable the
 glass pane, and they have to wait until the submit has completed
 successfully.  I see nothing wrong with this approach:

 PopupPanel loadingDialog = new PopupPanel();
 loadingDialog.setWidget(loadingImageAnimation);
 loadingDialog.setGlassEnabled(true);
 loadingDialog.center();

 .. do the work

 onSuccess and onFailure callback
 loadingDialog.hide();

  I wouldn't popup (block user interaction) over the whole page! Just
  the component that needs to load. In fact you don't even need to block
  user interaction. I just do it in my application because (for example)
  the user has clicked refresh on a component and any interaction with

Re: Using Javascript Overlays vs. Manually setting up POJO instances?

You have also some framework like piriti allowing easy mapping between
JSON and Java object. But I don't like them because their overhead. I
use another approach.

My model is made of interfaces. I share the interfaces between the
server and GWT. For GWT, I have a generator that automatically
implements the interface as a wrapper around the JSO. This wrapper is
a zero-overhead implementation (just method forward).

You can find my generator here if it can help you:
http://code.google.com/p/tyco/source/browse/trunk/tyco-gwt/src/main/com/googlecode/tyco/gwt/tikray
And you have some unittests here:

and use the JsonParser, or b) write a 2nd implementation of my classes
using Javascript overlays?

I don't really like either approach, one option means having 2 types
of objects that I would need to keep in sync (the pojo and the
Javascript overlay) and the other way means I have to traverse the
Json myself, populating my object glyph manually.
Either way, ouch.

Re: Using JavaScript Overlay Types for Nested JavaScriptObjects

Hi,

Imagine you have this in your HTML page:
-
html
  ...
  script
window.data = { prop1 : { prop2: 42 } };
  /script
  ...
/hmtl
-

First create a JSO for the prop1 value:
class InnerJSO extends JSO {
  protected InnerJSO() {}
  public native int getProp2() /*-{ return this.prop2; }-*/;
}

Second create the outer JSO (the data value):
class OuterJSO extends JSO {
  protected OuterJSO() {}
  public native InnerJSO getProp1() /*-{ return this.prop1; }-*/;
}

Finally create a method that returns data:
public native OuterJSO getData() /*-{ return $wnd.data; }-*/;

Okay? Do you need more explanation?

Re: Does entire IncrementalCommand run in one tick?

 Do all steps of an IncrementalCommand run in one tick, or does it

 i.e. will the 2nd deferred cmd (i.e. the cleanup step) always only run
 after the incremental command is done, or can it creep in between
 steps of the incremental command?

 Thanks much for replies!

Your incremental command will execute once, then the deferred command,
then the incremental command again during at most 100ms (I mean,
repeating, and GWT will check between each call whether the total was
less than 100ms so it can call once more, or not; because JS is single-
threaded); and only then it'll yield to the browser. And if you
incremental command wasn't done (i.e. returned true), then quickly
after it'll start executing again, repeating for at most 100ms before
yielding to the browser, etc.

Well, this is from memory, maybe it's rather how Scheduler works
rather than DeferredCommand. But ther'll be one call to the
incremental command, then the call to the deferred command, then only
the remaining calls to the incremental command.

 So is there a way I can hook my code before the actual change occurs?

No, and you can't prevent the browser from changing the history.
What GMail does is that it lets the history in an inconsistent state.

 Can somone please tell me why I get these errors? Did I forgot other
 modules?

I believe your app's gwt.xml is in myproject, and it has a source
path=client / (or no source/ at all, which is equivalent). If
that's the case, then the interfaces aren't within the
myproject.client package so you can't use them right away.
You have to either move the interfaces into you module's client source
path (myproject.client package or a subpackage) or create a module
(say in resources and with source path=strings/, or in
resources.strings and with source path=/) that you then inherit.

The only problem I found with this interface technique (which I immediately

Re: Using jqPlot library (javascript chart) with the MVP pattern

2010-06-10 Thread Rizen

Thank you very much for this explication. However I had already added
a div id=chart1/div Element into the HTML page to be sure that
it was adding correctly. But I will use your method for the wrapper.

After this I make two different test.
First I used only the JQuery library with a simple $wnd.$
('#chart1').text('Salut');. It works perfectly and Salut has been
added inside the div Element.

The same method just replacing the code with the chart's code print
the error message : $ is not defined. So it seems that the problem
comes from jqPlot only. I developped also a simple HTML page with the
chart's code and all is ok. As a result my external jqPlot file
doesn't have some problems (hopefully).

So now I don't know if there is a conflict between JQuery and jqPlot,
but I'm going to make some others test.
Thank you.

Re: 1 layout - 3 browsers - 3 results?

Hi Alejandro,

thank you very much!!!
This solution seems to be perfect for me!

I played around a little bit. I Changed the base class for the
ChessTable to DockLayoutPanel, to add some annotations to the chess
board. This worked, too!

Then I inserted a grid into the center section of ChessTable. It's
clear that this was not centered.
May I use the same mechanism to center this grid within the
ChessTable?

I understand the mechanism as follows:

- create a new class, which implements RequiresResize
- write a onResize method which centers this object within the parent

Well, it works great on FF and IE. Good job!

Thanks again!

GWT Localistion for Large Enterprise apps

2010-06-10 Thread Brian

Hi,

I am developing a massive enterprise application from scratch using
GWT.
I want to use GWT's implementation of localisation but I have some
concerns with performance.
I will have thousands of labels across all my screens that will
require conversion to the appropriate language. Do I have to put all
these label tags into one .properties file? If so, I fear this will
add alot of time to the application startup.
Another approach I was thinking of taking was having multiple
properties files per module and implementing code splitting for each
module. Will code splitting work with loading locale properties files?

It would be great to hear of other people's experience developing
large enterprise apps with regards to localisation.

Thanks

Re: Using Javascript Overlays vs. Manually setting up POJO instances?

My TNativeList is a list-like wrapper around a JS array (http://
code.google.com/p/tyco/source/browse/trunk/tyco-gwt/src/main/com/
googlecode/tyco/gwt/tikray/client/TNativeList.java). It is used by
TList, a List implementation that maps a JS array to a List without
(too much) overhead.

The following unittest is an example of ListString member:
http://code.google.com/p/tyco/source/browse/trunk/tyco-gwt/src/test/com/googlecode/tyco/gwt/tikray/client/collection/GwtTestCollection.java
. I plan to reduce this code be providing a default list where the
list if null.

Currently, my code allows the members of:
- primitive types (int, boolean...)
- wrapper types (Integer, Boolean...)
- String
- Collection/List of wrapper types or String
- Collection/List of JSO
- Collection/List of TObject (something generated by my generator)

Adding Map is not so hard, I just have no need it before ;).

com.google.gwt.core.client.JavaScriptException: (TypeError): methodTable[2] is not a function

Hi guys,


I have just upgraded my web application from GWT 1.5 to GWT 2.0.3 and
I get this error:

uncaught exception: com.google.gwt.core.client.JavaScriptException:

7ED6F3C652B9A90CD7E6F789A9414211.cache.html:33827

It looks like it is linked to the serialization but the classes
serialized are exactly the ones that were perfectly serialized by GWT
1.5
I must say I am completely stuck on this one and I don't see anyway to
debug.

Does anybody know about this ? Any idea about how to nail down the
issue ?

Many thanks !

Google visualization over HTTPS

I am using GWT 2.0.3 and have a page, compiled as client-side Java
code
into JavaScript containing a Google Visualization chart included in
the Java code with VisualizationUtils.loadVisualizationApi.

This page is delivered over https.

The problem being that the call to retrieve the chart from the
compiled javascript is made over http and browsers, especially IE
create warnings that pop up about insecure items being imported into
the secure page.

Is there any way to specify an option in the Java code or the setup
(*.gwt.xml file) so that the http request to retrieve the chart is
made over https ?

app engine with hosted mode

2010-06-10 Thread alexh

Hi,

I am currently developing a GWT application that will run on Google
App Engine. I have chosen to use Maven and am running my application
from the command line for debugging and testing. What I would like to
be able to do is run my application in the GWT 2.0 hosted environment
but still initialize the App Engine runtime. Can someone help me out
with what I need to configure in order to make this happen? I'm
currently using gwt-maven-plugin in my pom.xml. Any help with this
would be greatly appreciated.

Thanks,

Alex

Does @DefaultMessage and @PluralText really work?

2010-06-10 Thread PEZ

I'm making (porting really) a relative time module for human
readable date-and-time messages to GWT. The first (alpha-ish) version
is up on Github: http://github.com/PEZ/GWT-Relative-Time

Anyone who tries it will notice that it reports all times as plurals.
When it should say an hour ago, it says 1 hours ago. My messages
interface looks like so:

public interface TimeMessages extends Messages {
...
@DefaultMessage({0} {1,number} hours {2})
@PluralText({one, an hour})
String hours(String prefix, @PluralCount int count, String
suffix);
...
}

From what I can understand of the documentation, that is how you
should be able to deal with singular and plural forms, right? Well, it
doesn't work. Anyone who knows how this works? Or, if it's a bug in
GWT, can I work myself around it?

Re: Get today's date, and the first day of this week's date?

2010-06-10 Thread Nicholas

To answer #6: I asked the GWT team about this during the fireside chat at
I/O this year.  They appeared to be caught off guard by the question but
eventually came out and said that they have no plans on resolving this
issue.  I kind of got the feeling that this was the first time that it came
up to them.  We have attempted to tackle this issue in two different ways.
 We first made a DateUtil class that wrapped up all of the deprecated
methods that we used from java.util.Date.  This was an OK solution but it
seemed really dirty.   Then a co-worker went about modifying Joda Time (
http://joda-time.sourceforge.net/) for the purpose of using it within GWT.
 The result was gwt-time (http://code.google.com/p/gwt-time/).  It is usable
but it is considered alpha as there is much work to be done with it before
it is ready for GWT prime time.  It is our hope that we will be able to make
this a rich implementation of the joda time API that plays well in GWT land.
 Unfortunately neither of the contributors have had much time to hack away
at it lately.

 Hey guys, I just found out that the Java Calendar class isn't

 help would be appreciated.

 1. Get today's date.
 2. Using the current date, get the date of the first day of the week
 (Sunday), and I think I might need to know how to get the end date
 also.
 3. How to Add and subtract a number of days to a date.
 4. I need to know how to parse all the above questions information
 into a string.

 Off the top of my head, that's what I'm trying to do. 1 More question:
 5. Would it improve performance while handling a start date and an end
 date for an event, instead of keeping an end date, calculating the
 duration that the event would last, rather than calculating the date?
 Would it even be worth it? (A friend recommended this)

 6. Are we seeing any updates coming for working with dates? I'm
 currently using GWT 2.03.

Re: quirks vs. standard mode

2010-06-10 Thread Ata

 In GWT some widgets only work properly in quirks or standard mode, not
 both. As far as I could tell I should be running the app in standard
 mode because I have !doctype html as the first line of the root HTML
 page, however widgets like TabLayoutPanel that are supposed to work in
 standard mode don't work, and the quirks mode ones do. I'm using IE6
 (I can also try with chrome and IE8 later, but it should work with any
 browser). Does anyone know why this quirks/standard mode is not
 working as advertised? Could it be a browser thing, or am I really NOT
 in standard mode even though I think I am, or is the GWT documentation
 just lying to me?

Re: quirks vs. standard mode

2010-06-10 Thread Daniel Le Clere

Ummm... IE 6 doesn't have a standards mode... Adding that doctype is
probably just causing more issues. The HTML 5 doctype is useful for
forcing IE 7 and 8 into standards mode. If you want to get your
program rolling for IE 6 you're going to have to write some specific
views under the MVC or accept greater restrictions in your overall
design. GWT is not magic, it cannot force IE 6 to do something that
was not accounted for in its design. If you want that kind of magic
try Google Frame :)

Re: GWT Localistion for Large Enterprise apps

2010-06-10 Thread Stefan Bachert

Hi Brian,

let us calculate

1000 Labels, average 10 characters in size.
makes 10KByte

How fast do you expect your network?
10KB/s - 10 Sec (Modem)
100KB/s - 1 Sec (ISDN)
1MB/s - 0.1 Sec (DSL)
10MB/s - 0.01 Sec (ADSL)
100MB/s - 0.001 Sec (intranet)

How often this addition time applies?
Exactly the first time you download the app. After that, it is in the
cache.
OK, each release requires a further download

When your figures are in that range, is it really worth to care about
it?

Do what is good for modularisation but do not care about download
performance.

 Hi,

 I am developing a massive enterprise application from scratch using

 I want to use GWT's implementation of localisation but I have some
 concerns with performance.
 I will have thousands of labels across all my screens that will
 require conversion to the appropriate language. Do I have to put all
 these label tags into one .properties file? If so, I fear this will
 add alot of time to the application startup.
 Another approach I was thinking of taking was having multiple
 properties files per module and implementing code splitting for each
 module. Will code splitting work with loading locale properties files?

 It would be great to hear of other people's experience developing
 large enterprise apps with regards to localisation.

Re: Using jqPlot library (javascript chart) with the MVP pattern

Because the array is bound to the sub-frame used by GWT.

When you create an array using [], the Array function is called. This
is the same as new Array(). Then the following condition returns
true: [].constructor == Array.

But, there is an Array function for each frame. If you create an array
in one frame, and use the same comparison in another, it will returns
false.

You must create your array using new $wnd.Array(). That's another

Re: quirks vs. standard mode

2010-06-10 Thread Chris Lercher

Daniel, IE 6 does have something like a standards mode - it's not
really standards compliant, but it does behave differently, when
putting it into that mode. That's because, when it's in quirks mode,
then it behaves like IE 5.5. See http://www.quirksmode.org/css/quirksmode.html
for more details.

As far as I can tell, the new layout panels of GWT 2.x are designed to
also work on IE6 in its standards mode - sometimes by emulating CSS
properties with javascript.

@Ata: Try to use !DOCTYPE html (note the uppercase DOCTYPE). Make
sure, that it's the very first thing in the document (no comments or
anything in front of it!)


On Jun 10, 2:28 pm, Daniel Le Clere daniel.lecl...@gmail.com wrote:
 Ummm... IE 6 doesn't have a standards mode... Adding that doctype is
 probably just causing more issues. The HTML 5 doctype is useful for
 forcing IE 7 and 8 into standards mode. If you want to get your
 program rolling for IE 6 you're going to have to write some specific
 views under the MVC or accept greater restrictions in your overall
 design. GWT is not magic, it cannot force IE 6 to do something that
 was not accounted for in its design. If you want that kind of magic
 try Google Frame :)

Re: LayoutPanel question

2010-06-10 Thread Stefan Bachert

Hi Chris,

it is not really clear to me.
Did you switched of the added child, or the layer (div) containing the
added child.
The first is not suffient and will leave the layer (div).

I think, the correct method to get the layer div of any child widgets
is
getWidgetContainerElement.

Call this and set the visibiltity

 Hi there

 I'm trying to hide a layer in my LayoutPanel. The idea is to have a
 layer act a bit like a popup, but it's not really a popup, and it
 makes it easier if it is a layer.

 I'm trying to hide it, so I toggle the layer child (a simplePanel)'s
 visibility property on/off, which seems to work fine, but it leaves a
 div element (from the layer I suppose), which means I can't click
 through to the elements behind it... When I look at the DOM, I get a
 div with all the properties from my layer, and then the div inside
 that is the SimplePanel I'm using.

 Any ideas? I guess i could just ask for the widget's parent? But that
 seems hacky. Am I doing something wrong?

mean the Datastore class in GWT framework.

Even GWT is very good for creating nice GUI on the client side, it's
object-relational mapping is still in incubation period and you
following options how to proceed:
1.) You need to manually write the functions which manipulate with
data on the server side and call it via AJAX (JavaScript) from the
client side when necessary.
2.) Look at EoD SQL project athttp://eodsql.sourceforge.net/this
library may help you, there are also tutorials how to use it together
with GWT
3.) This is the easiest, free for trial then payed, option. Use
SmartGWT Professional or Enterprise. Take a look at it
http://code.google.com/p/smartgwt/. It has integrated tomcat inside.
In the SDK there are lot of examples and tutorials, but also something
what you will find maybe really useful:
Datasource generator - generate XML DS descriptional file, works with
standard database engines, etc.
Visual designer - you can create client layouts in visual way, in this
tool you are also able to use for example Datagrid directly with
Datasource you created in generator, and you have component directly
interacting with any datasource.

I found SmartGWT SDK best for learning, as standard GWT, you have
access to all Java, XML files, but from Visual designer you also
generate JSP file and can see what have you created.

Hope I helped you. Also send me your experiences I you already found
something better, different.

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

2010-06-10 Thread Brian Reilly

I've had good luck with the second (non-invasive) approach. A coworker
of mine implemented the first (using Spring MVC) approach and it did
work for the most part. However, we aren't otherwise using Spring MVC
and don't have any broad expertise in it, so I was initially confused
when looking at it. Specifically, I didn't know about the relationship
between the servlet name and the -servlet.xml file, the contents of
which require some learning to understand (i.e.,
SimpleUrlHandlerMapping and its mappings property). I also didn't
like the additional wrapper GwtRpcController around the actual
service; it seems like an unnecessary layer. I think this setup keeps
you from having to extend RemoteServiceServlet, but you still have to
worry about GWT serialization of parameters and return values so I
don't see it as a big gain. Also, the proxy means that you lose
getThreadLocalRequest unless you add code to the GwtRpcController to
forward it to your service.

I like the non-invasive approach because it keeps the setup of the GWT-
RPC servlet exactly as explained in the GWT documentation. Your spring-
configured services don't change either. You just gain the ability to
inject those services into your GWT-RPC remote servlets.

I think it comes down to where you're coming from. If you already use
and like Spring MVC, you'll probably prefer the first approach. (I
hope someone with that perspective also responds to describe the
benefits of that setup.) If you like GWT and just need to integrate
with your spring-configured services, you'll probably prefer the
second approach.

 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-...),
 but also other where integration is done without it 
 (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.

you can try this:

if (enabled) {
this.removeStyleName(disabled);
} else {
this.addStyleName(disabled);
}
}

public boolean isEnabled() {
return !DOM.getElementPropertyBoolean(getElement(), disabled);
}

// css
.disabled {
cursor: default ! important;
color: #888 ! important;
}

Extend DatePicker, add these two methods. The only problem is that you have
to check on every event if the DatePicker is enabled or not...

Re: Cleaning up threads on GWT application shutdown

Technically, the proper way according to the specs is to not utilize
background threads.  Of course, since nobody actually obeys that
proclamation, use a ServletContextListener to start your Thread when
the servlet context is started and stop the thread when the context is
being destroyed.  In general, that's the proper way to do any init /
teardown work in a web application.

uibinder file to access an image in a ClientBundle?

I've tried the following which Chris Ramsdale at Google claimed would
workhttp://groups.google.com/group/google-web-toolkit/browse_thread/thread/ed48cc0ddde4b52fbut
it doesn't:

ui:with field=theme type=com.companyname.resources.ThemeManager /
ui:image field=myimage resource={theme.res.globalrelaylogounity}/
ui:style
 @sprite .header {
  gwt-image: 'myimage';
 }
/ui:style

I can't use ui:image src= because I definitely can't put a hard-coded
path there because it needs change if the user changes themes. I'm grabbing
the ClientBundle from ThemeManager.res(). We need to be able to switch
themes, which involves switching the ClientBundle being used. I've tried
putting an expression in src= using curly braces to get the path dynamically
but that doesn't work.

The only alternative I can think of is to layout the UI in java code which
sucks.

Re: Access ClientBundle ImageResource from UiBinder

2010-06-10 Thread David Grant

The other solution which seems to work is that I can put

@sprite .header {
gwt-image: 'myimage';
}

in a css file and reference it as a CssResource in a ClientBundle...then it
will look for an image resource called 'myimage' in that ClientBundle.

it works but it just puts stuff in to the css file associated with my global
theme that I would rather just keep local to my widget.

Haven't tried, but should not matter.

Re: 1 layout - 3 browsers - 3 results?

Hi,

there is a strange problem with the menubar in your example using IE8
(not with FF).

When it opens a popup menu, the whole page disappears and only the
popup menu is visible.

The popup menu is added to the menubar as follows:

MenuBar m= new MenuBar (true);
m.addItem (Login, (Command)null);
m.addItem (Logout,(Command)null);
m.addItem (Register,(Command)null);
m.addItem (Profile,(Command)null);
menu.addItem (Account,m);

What's that again?

Hi Alejandro,

thank you very much!!!
This solution seems to be perfect for me!

I played around a little bit. I Changed the base class for the
ChessTable to DockLayoutPanel, to add some annotations to the chess
board. This worked, too!

Then I inserted a grid into the center section of ChessTable. It's
clear that this was not centered.
May I use the same mechanism to center this grid within the
ChessTable?

I understand the mechanism as follows:

- create a new class, which implements RequiresResize
- write a onResize method which centers this object within the parent

Well, it works great on FF and IE. Good job!

Thanks again!

Hi Alejandro,

this looks very good and I am still analyzing the java code. I will
give you a more detailed feedback later...

The java code looks clean, but the html file is pumped up with of
JavaScript.
Does this code belong to the solution or is it just generated from
other sources?

opening popup menu hides all remaining page content

Hello,

I found a strange problem under IE 7:

When I click on a menu item that opens a popup submenu, the whole page
content (all widgets including the menubar itself) is hidden and only
the popup menu is visible.

I reduced the code to a minimum example and added it at the end of
this posting. There is no other code and no CSS, just the empty
project created with the eclipse plugin.

Since there is nothing special in this code, I assume that this
problem must be known to others.

Thank you
Magnus
