Really interesting. I'll see what I can do with it in our project.

Thanks! :-)

Re: asm.js support?

[Colin Alworth]

There have been a few quick discussions about this in ##gwt on irc, and 
while I think we probably need to both move this to -contrib before much 
longer but also get some of the compiler experts involved, I suspect this 
is going to end up being a specific tool to optimize sufficiently c-like 
methods, not the entire application. 

The asm.js 'language' restricts down to just a few things - a TypedArray 
for a heap, standard lib (math, etc), and a variety of primitives. Within 
each module you can declare individual functions (as well as arrays of 
functions to do vtable sorts of things), and return a set of named 
functions to allow outside code to call into this asm-ified code.

This appears to greatly limit what code can do. Since you are confined to a 
heap, there is no free GC, it has to be implemented (or garbage collect the 
whole heap with the rest of the module). 

Since the set of functions in the module is 'exported', and the module may 
be given a set of 'foreign' functions, it seems likely that individual GWT 
methods could be compiled to asm-compatible code if they meet certain 
criteria. The more complex the data going in and out is (i.e. serializing 
strings or complete objects to the 'heap', then deserializing to call 
foreign functions or to return again), the more expensive that each call 
will end up being, so either methods must opt in to this (via an annotation 
perhaps?), or the compiler has to have a pretty specific heuristic to 
decide if a method is eligible or not (for example, 'does this method take 
only primitive/primitive[] arguments, use only primitive/primitive[] 
fields, return a primitive/primitive[] value, and call only other methods 
which meet this same criteria?').  Then, methods should be grouped so that 
they share a heap and are only compiled once, so that they can start to 
deal with field in a consistent way without encoding/decoding (i.e. asm-ify 
all of an object's methods, store its fields in the heap, and GC the whole 
heap when the object itself goes away, and expose methods that can read out 
fields (getters/setters) directly from that heap).

In short, the developer will likely need to be very aware of what GWT is 
going to try to do it their code and monitor something like the compiler 
report to see why a particular slow method isn't getting asm-ified. Ümit's 
point is probably right that for general purpose code, compiling code that 
the browser can handle efficiently while still viewing it as JS is a far 
easier win. But since the asm-ification has to be done to the JS code 
itself, I doubt that simply a library will make it possible to produce 
asm-compatible code, but instead that the compiler will need to be aware 
and actively participating, unless all such code is to be written in JSNI.

Re: gwt 2.6 SuperDevMode and injected css problem

[Colin Alworth]

Can you confirm that you are hitting the Compile button in each browser and 
that the SDM console is indicating that it is recompiling for each other 
user agent? It sounds as though you might be compiling when you start up 
one browser, then just turning dev mode on without recompiling in other 
browsers.

Help to create Lightweight widgets

[Axel R]

Hi,
I know there is a lot of doc in the web, but I cannot understand well many 
things...please feel free to help me:

#1 Does addClickListener() and addClickHandler() does the exact same thing 
(listener is just deprecated) ?

#2 I have created the following widget:

public class AreaPlaceHolder__TA_heavy extends TextArea 
{...
addFocusHandler(new FocusHandler() ...
addBlurHandler(new BlurHandler() ...
...}

BecauseI just have a onBlur and onFocus events to intercept, so I would 
like to optimise this widget such as :

public class AreaPlaceHolder__TA_light extends AreaElement implements 
BlurHandler, FocusHandler
{...
public void onFocus(FocusEvent event)...
public void onBlur(BlurEvent event)...
}...

- Is it the good/best way to have a lighter version of  
AreaPlaceHolder__TA_heavy  (and to always be able to use it in UI Binder)?

#3 When I create my own widget, I do not know 
 - when to extend Widget ?
 - when to extend Composite ?
 - when I am free to extend neither of them ? (I do not know if I need to 
at least extend one of them)

#4 Finally, I really would like to use event Bubbling, there is a lot of 
'little' code on the net, but nothing satisfy me...I mean, I would like to 
write a little class where a HTMLPanel has 3 differents ButtonElement and the 
HTMLPanel intercepts :
 - a clickEvent on button1 and say "hello 1" 
 - a clickEvent on button2 and say "hello 2" 
 - a clickEvent on button3 and say "hello 3"

I just see complicated all theses DOM manipulation, sink event so if you 
can give me the little example I need, I think I will be able to replace a 
lot of widgets by there Elements and reduce a lot my code (useful for the 
mobile version).

Thanks you a lot,
Axel

gwt 2.6 SuperDevMode and injected css problem

[Vassilis Virvilis]

Helo everybody,

I have enabled super dev mode and it works ok in chrome but fails in 
firefox and internet explorer.


More specifically

I added




in my gwt.xml

My application requires some css to be injected with

Resources.INSTANCE.css().ensureInjected();

which I do as the first thing in onModuleLoad()

When dev mode is on (the bookmartlet) everything is working in all browsers
When dev mode if off only chrome is working. In firefox and IE css 
resources are not injected.


Any ideas?

 Vassilis

CalendarUtil is a GWT class that can not be used on the server. Use 
java.util.Calendar or JodaTime library.

You can avoid these issues by not blindly use classes available in 
Eclipse/IntelliJ. Only classes from jar files in war/WEB-INF/lib are 
available on the server.

ok thanks.. i'll try your solution.. However sorry for my stupid questions
but i'm a newby on GWT and java.. ;) The source Code at line 707 is
something like this:

SimpleDateFormat df = new SimpleDateFormat("dd/MM/");
String data = "04/02/2014";
Date d = df.parse(data);

I think you just have mistakenly chosen the wrong import of 
SimpleDateFormat. gwt-user.jar contains com.ibm.icu.text.SimpleDateFormat 
but gwt-user.jar will not be deployed on the server. I think you want to 
change the import to java.text.SimpleDateFormat in your server side class.

com.pannelli.controllo.server.GreetingServiceImpl.SQL_fasi_c

com.pannelli.controllo.server is the package of the server
GreetingServiceImpl is the java class for the server
SQL_fasi_ciclo_per_tipologia(GreetingServiceImpl.java:707)  is a function

However i have to change only the library??

If you do use SimpleDateFormat from ICU (com.ibm.icu.text.SimpleDateFormat, 
as opposed to java.text.SimpleDateFormat), then you have to ship it within 
your WAR.

Out of curiosity, what's at 
com.pannelli.controllo.server.GreetingServiceImpl.SQL_fasi_ciclo_per_tipologia(GreetingServiceImpl.java:707)
 
?

Re: How to fix the Column Ordering issue when Insert and Remove columns in GWT?

[Thomas Broyer]

Sure, the index to insert at is the "original" minus the number of hidden 
columns before it; or put differently, the number of visible columns before 
it. In any case, it means tracking the visible state of your columns.

You could use an array of booleans representing the visible state of your 
columns (by their "original" index), and therefore count the number of 
visible/invisible columns.
Or each column could know its predecessor, in a linked list fashion, and 
its visible state, so you could ask the column to compute its "current 
index" based on its predecessor's index and its visible state (recursively).

How to fix the Column Ordering issue when Insert and Remove columns in GWT?

[Tom]

 

I have a cellTable that has many columns like the followings:

OrderID - OrderDate - OrderTime - Name .
1 - 2012-01-05 - 11:12:12 - Tom.. 

Each column will have a checkBox for Hide/Unhide column:

[x] orderID (CheckBox)
[x] orderDate (CheckBox)
[x] orderTime (CheckBox)
..

Requirement: I want that when users uncheck the CheckBox the corresponding 
column will disappear & when they check the CheckBox, the column will 
appear in the CORRECT ORDER as at the beginning. This is the code:

public void insertColumn(int beforeIndex, TextColumn textColumn, 
String columnName){
if(getView().getOrderListCellTable().getColumnIndex(textColumn)==-1){
getView().getOrderListCellTable().insertColumn(beforeIndex,textColumn, 
columnName);
textColumn.setSortable(true);
}
}
public void removeColumn(TextColumn textColumn){
int index= getView().getOrderListCellTable().getColumnIndex(textColumn);

if(index!=-1){
getView().getOrderListCellTable().removeColumn(index);
}
}

However, I got this issue, when I hide / unhinde just 1 column then the 
order is OK, ex, hide orderDate column then the table will be like this:

OrderID - OrderTime - Name .
1 - 11:12:12 - Tom.. 

And ofcourse, when unhiding orderDate then it will go back to the beginning 
correctly. 

Code to insert/remove orderDate

getView().getOrderDateCheckBox().addClickHandler(new ClickHandler(){

@Override
public void onClick(ClickEvent event)   {   
if(getView().getOrderDateCheckBox().getValue()){

insertColumn(1, orderDateColumn,"Order Date");
}
else{
removeColumn(orderDateColumn);
}
}

});

But if I hide both orderID & OrderDate & then unhide orderDate then it will 
be like this:

OrderTime - OrderDate - Name .
11:12:12 - 2012-01-05 - Tom.. 

This is not right cos he orderDate should be stand before orderTime. This 
cos I insertColumn(1, orderDateColumn,"Order Date"); at position 1 (before 
index).

Can you figure out a logic to fix this issue?

We'll give it a go once time allows...
Why don't you post some screenshots or deploy a sample web app ( on

It probably is impacted by the JDK change, but GWT does not use that 
feature (AFAICT and IIUC)

Re: GWT 2.6.0 now available

Great news.

I have a question on the included thirtparty products. I see that there is 
a guava version in there.

Is this version impacted by the JDK 1.7.0 update 51 issue reported here:
https://code.google.com/p/guava-libraries/issues/detail?id=1635

Maybe you are not using the features that cause the incompatiblity, but I 
am just checking since we plan to migrate to this version of java in our 
build environment.

GWT Desktop-Notification

[Marcel K]

Hey,

after some coding with gwt i want to publish a component that i wrote. It's 
an api for desktop-notification and should work with Chrome, FF and Safari 
(according to 
https://developer.mozilla.org/en-US/docs/Web/API/notification#Browser_compatibility
).

I would really appreciate if someone could take a look at it and maybe give 
me some advices ;) or.. maybe even use :)
