Hi,
I have a label that contains some text and part of it must link:
For example the whole Label text is : bla bla bla. Reference:link, bla bla
bla.
I tried : Reference : a href=http://www.google.com;Help Desk/a
But gwt doesn't detect it as url, may be i should use HTML?

Regards.

Re: Rounded Corner In Gwt Button

For my custom buttons i use Flex Table with 1 row and 3 columns: left,
repeat and right, where left and right are images with rounded corners and
repeat is 1px width image that is repeated.
I also have predefined styles that are placed in enum. The only problem here
is that my images are not in bundle, but it can easily be done with bundle.
At the and is the css.
Here is an example:

public class ImageButton extends FlexTable {

public enum Style {
HEADER, TABLE_CLOSE;

private static String fromEnum(Style i) {
switch (i) {
case HEADER:
return header-image-button;
case TABLE_CLOSE:
return table-close-image-button;
default:
return header-image-button;
}
}
}

private final HTML left = new HTML();
private final HTML middle = new HTML();
private final HTML right = new HTML();
private final CellFormatter cf = getCellFormatter();

public ImageButton(String title, Style style) {
this(style);
middle.setText(title);
}

public ImageButton(Style style) {
// make all flex table cells like one
this.setBorderWidth(0);
this.setCellPadding(0);
this.setCellSpacing(0);
this.setWidget(0, 0, left);
// cf.setWidth(0, 0, 6px);

this.setWidget(0, 1, middle);
middle.setHorizontalAlignment(HasHorizontalAlignment.ALIGN_CENTER);
cf.setVerticalAlignment(0, 1, HasVerticalAlignment.ALIGN_MIDDLE);
cf.setHorizontalAlignment(0, 1,
HasHorizontalAlignment.ALIGN_CENTER);
this.setWidget(0, 2, right);
// cf.setWidth(0, 2, 7px);
setOverridenStyleName(style);
}

private void setOverridenStyleName(Style style) {
super.setStyleName(Style.fromEnum(style));
switch (style) {
case HEADER:
setLeftStyleName(bg-left);
setRightStyleName(bg-right);
setMiddleStyleName(bg-repeat);
break;
case TABLE_CLOSE:
setLeftStyleName(left-table-close-button);
setRightStyleName(right-table-close-button);
setMiddleStyleName(repeat-table-close-button);
break;
}
}

public void setLeftStyleName(String style) {
cf.setStyleName(0, 0, style);
}

public void setMiddleStyleName(String style) {
cf.setStyleName(0, 1, style);
}

public void setRightStyleName(String style) {
cf.setStyleName(0, 2, style);
}

@Override
public void setTitle(String title) {
middle.setText(title);
}

@Override
public String getTitle() {
return middle.getText();
}

public void setEnabled(boolean enabled) {
DOM.setElementPropertyBoolean(getElement(), disabled, !enabled);
if (enabled) {
this.removeStyleName(disabled-button);
} else {
this.addStyleName(disabled-button);
}
}

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


CSS:

bg-left {
background-image: url(left.gif);
background-repeat: no-repeat;
}

.bg-repeat {
background-image: url(repeat.gif);
background-repeat: repeat-x;
}

.bg-right {
background-image: url(right.gif);
background-repeat: no-repeat;
}

USE IT:
ImageButton b1 = new ImageButton(Style.HEADER);
Hope this help.

Re: RootPanel.get().clear() does not clear the page

 Hi,
 Thanks for your reply.
 I have not tested but I think getElement().setInnerHTML will work.

 First, I thought that I can juse use RootPanel.get().clear() to remove 
 everything on the current page; then I hope I can use something like 
 RootPanel.get(id).clear() if I have sometign like this in my html file:
  div id=id/div
 But it does not work..

 So looks like I need to use setInnerHTML.

You should really use the clear() method of your different RootPanels,
or you'll leak memory (until the user leaves the page and/or closes
his browser window/tab).

Re: java.io.Serializable not accepted for serialization

2010-02-10 Thread Andrea Polci

Yes it is.

Meanwhile We've found the source of problems.
We have a dispatcher servlet so that we don't need to register our
services in the web.xml file.
The code for this servlet was probably taken from an example that was
using an old version of GWT that didn't need to pass the
SerializationPolicy and SerializationPolicyProvider to the RPC
methods.

Now the problem is solved.

Thanks the same for your help.

Re: can not set breakpoint

2010-02-10 Thread Ashar Lohmar

that's the problem you are missing the ?gwt.codesvr=localhost:9997
from the URL, all the urls need to have that so that your application
will comunicate with the eclipse so you'll be able to debug i think
that's specified somewhere in the docs.

also if you don't have ?gwt.codesvr=localhost:9997 on the url, you
won't see the client modfications if you refresh the browser.

cheers,
take a glance on the documentation for development mode

Re: Not able to use External Jar file for DB connection

2010-02-10 Thread Ashar Lohmar

what JDK do you use ?
JDBC4 driver should be used only starting with JDK 1.6,
acording to the postgresql site : JDK 1.6 - JDBC4. Support for JDBC4
methods is limited. The driver builds, but the majority of new methods
are stubbed out.
maybe you will consider in using the JDBC3 version

in my apps, i put the jar in the war\WEB-INF\lib folder, and the using
eclipse I add it to the build path

but one more thing ... i just noticed ... why do you have the
appengine in a application that will use an normal SGBD ?
if i recall well, using appengine you won't be able to connect to the
database

any way hope any of this helps

Re: Not able to use External Jar file for DB connection

2010-02-10 Thread Bill Michell

Forgive me if I am wrong, but I was under the impression that the App Engine 
*required* you to use the database implementation it provided.

Either deselect the app engine option from your project, or abandon any 
attempts to use an alternate database.

Hi folks,

I'm trying to get GWT2.0.1development mode working with the -
noserver option. The main issue is that while running in development
mode, any changes I make in the GWT java classes are not reflected
when I refresh the browser.

This is a bit of a nonstandard setup, so let me outline it a bit.

We have a number of apps that depend on some other cvs modules:

* gwtapp1
* gwtapp2
* gwtlib1
* gwtlib2

All of these depend on code running on the server (json files, RPC)
and I couldn't figure out how to get them working with the built in
Jetty server. (For one thing, I couldn't figure out how to have the
different projects all compile into one WEB-INF/classes directory.)

gwtapp1 compiles the GWT into the root directory, and works just fine.

gwtapp2 compiles the GWT into /static/gwt/ One other difference that
may be relevant is that gwtapp2 uses the cross site linker. However,
removing that line from the .gwt.xml file didn't seem to make a
difference in the behavior. Another difference is the directory that
gwtapp2 compiles into actually has 3 different modules in it (but I'm
not trying to touch any of the other modules).

It works fine in 'production' mode, when built via ant. But it
doesn't work in development mode.

Here's the arguments I'm using for the eclipse launcher:

-noserver -startupUrlhttp://localhost:8080/HomePage.do
com.foo.gwtapp2 (I've tried different URLs, including a static html
page)

The GWT development mode window pops up just fine, but I never see the
'FF' tab pop up when I click 'launch default browser'. I do see this
url in the browser window:
http://localhost:8080/HomePage.do?gwt.codesvr=192.168.3.103:9997

I see no messages in the development mode window. However, when I
turn the logLevel up to DEBUG (-logLevel DEBUG) I see the 'Loading
Modules' line. When I am working with gwtapp1 (which works) I also
see a 'Connection received from xxx.xxx.xxx.xxx' message.

Before the 'Connection recieved', I see the following TRACE messages
when running either app:

00:00:02.078 [TRACE] Invoking Linker RPC policy file manifest
00:00:02.078 [TRACE] Invoking Linker Standard
00:00:02.094 [DEBUG] Attempting to optimize JS
00:00:02.141 [TRACE] Invoking Linker Export CompilationResult

artifacts
00:00:02.141 [TRACE] Linking compilation into C:\eclipse-workspace
\account\war\com.foo.gwtapp[12]

I imagine that the Connection is the issue, but am not quite sure how
to debug it.

I've installed the Google FF plugin, and am using FF 3.6. This is an
old project so it was not created with the google eclipse plugin.
Running on eclipse 3.4.2 on Windows XP, if that matters.

I've reviewed this
FAQ:http://code.google.com/webtoolkit/doc/latest/FAQ_DebuggingAndCompilin...

and made sure that I have all the .rpc files in the /static/gwt
directory. This directory is browser accessible (ie, when I put a
file here:http://localhost:8080/static/gwt/a.txt, I can read it with
my browser).

I also played around with the -codeServerPort argument, but that
didn't seem to make any difference. In the thought that it was
perhaps a urlrewrite issue (gwtapp2 does some url rewriting) I put a
static html file in the /static/gwt directory, but that still didn't
lead to a Connection being made.

I have done some searching on the web and in the GWT google group, but
haven't found much else. I also didn't find anything when searching
through the bug list.

What am I missing? Can anyone give me further places I should look or
ideas?

Thanks,
Dan

Re: Rounded Corner In Gwt Button

2010-02-10 Thread George Georgovassilis

There is a way using a button with the sliding door techique [1]. The
example does it with a link simulating a button, but it also works
with buttons.
Please be advised that buttons pose an unforseen behavior when
pressed: they displace their content by a few pixels. Unfortunately
not all browsers report that state correctly (depends whether the
button is clicked with the mouse or the keyboard) and you might be
stuck occasionally with a few uggly artifacts.

Re: Click handler not called

2010-02-10 Thread Sydney

I found out the problem. When I created the SimpleButtonPresenter in
the ContainerPresenter constructor, I created the SimpleButtonView but
it was not the one displayed on the screen. The one displayed on the
screen was the one created in the ContainerView. The fix:

In ContainerPresenter:

public interface Display {
Widget asWidget();

SimpleButtonPresenter.Display getSimpleButtonDisplay();
}
In the constructor
simpleButtonPresenter = new SimpleButtonPresenter(eventBus,
display.getSimpleButtonDisplay());

In ContainerView:
@Override
public Display getSimpleButtonDisplay() {
return sbv;
}

Re: Can't get dev mode on external server working (GWT 2.0)

2010-02-10 Thread Chris Jones

Hi Swami,

I was having a similar issue that you are describing.  I found that
removing the rename-to attribute from the module tag helped.  This
does mean that when you do a GWT compile it will compile to a folder
that has the whole package string of you module xml.  So you will have
to change your html to reflect that:

script type=text/javascript language=javascript
src=com.some.package.App/com.some.package.App.nocache.js/script

Hope this helps.

Hi,

as you wrote, label doesn't allow rendering HTML,
you should use HTML for external link:

HTML externalLink = new HTML(a href='http://www.google.com'Help

or for internal link

Hiperlink = new Hyperlink ( test.getLink(), test.getLink());

Overnight The response could not be deserialized

2010-02-10 Thread Nicolas Gramlich

Hi guys,

I have a pretty strange problem. I have a rather simply GAE-App,
located here: http://3.latest.honstatslogger.appspot.com/ (I'll try to
keep that version so the bug can be inspected in the future)

There are two methods on the RPC-Class and one is performing
normally:
#
void addPlayer(final String pPlayerName, final AsyncCallbackBoolean
pCallback);
#

The signature of the RPC that causes the _problem_ is this one:
#
void getPlayerStats(final String pPlayerName, final
AsyncCallbackCollectionPlayerStatsEntry pCallback);
#
[PlayerStatsEntry is persisted using JDO what worked perfectly fine
and still is working perfectly fine (see bottom).]

The exception I get on the _client_ side is (due to the GAE-Logs,
nothing is crashing on the _server_ side):
#
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
The response could not be deserialized
#

I can verify that the problem occuring is not related to a change of
the code. (I was asleep when it occurred first)

The implementation of the above RPC ends with (Its Scala code but as
it worked before it's not a Scala issue):
#
LOG.warning(Result:  + result.toString)
return result
#

To narrow the problem-scope I added a new single dataset to the
server, (usually more than one gets returned) with very simple data,
so I could easily see a failure in the data-strucutre, but there was
none.
This is what gets logged to the server (simple generated toString of
the class):
#
Result: [PlayerStatsEntry [AP=1, APEM=1, AR=1, AREM=1, acc_actions=1,
acc_amm_solo_count=1, acc_amm_solo_rating=1, acc_amm_team_count=1,

#
Perfectly valid data as I can tell you.

So I have absolutely no idea what is going wrong here and it would be
great if someone could help me on this as there are currently a couple
of hundred people waiting on this to be fixed =(

Big Thanks in advance!

GWT Composite with MVP

2010-02-10 Thread murugra

I am new to GWT and currently writing some stub programs to get used
to it. I had a look at the MVP Architecture presentation on the
website and tried some sample application. I struggling to find out
how to position my widget.

Overview of my dummy application.

This is a filtering application that has filter panel(List of
Listboxes) and main panel displays the results of the search criteria.

I have written 2 Composite Views and an appcontroller to control the
application.
1. FilterView
2. ResultOverviewView


table width = 1200px
  tr
td id=filterView align = left valign=top width=20%/
td
td id=resultView align = left width = 80%
valign=top/td
  /tr
/table

How do i force the composite view(ResultOverviewView to display inside
the resultView table.

GWT browser plugin + websense

2010-02-10 Thread Mart

Hi,

When I try to install the GWT Developer browser plugin, the
installation program tries to connect to tools.google.com and this
page is blocked by our websense software at work.

I *think* that all the required files are there, because the
GwtDevPluginSetup.exe installs a bunch of DLLs in the directory
\Document and Settings\username\Local Settings\Application Data
\Google\Update

The installation fails however when it tries to connect to
tools.google.com, presumably to install the update software (which I
do not want).  Is there a way to tell the installation program to
install the plugin anyway and not to try to connect to this web site?

JLayeredPane in gwt possible?

2010-02-10 Thread Samas

Hi, I want to reuse code from an older gui. There I used JLayeredPane.
Is it possible in gwt to create different Layeres containing each
objects?
The only solution I could find is using - in one panel - the same
position (top,left) of the widgets. But I hope for a solution where
the widgets are more separate - thus in different layer.

Thanks,

development mode console

2010-02-10 Thread levier

Hi all,

I'm getting a bit annoyed with the development mode console behavior
in Eclipse.
It always jumps up when something happens in the GWT application.
It jumps back when I close it.
If I put my editor full screen, it jumps over my editor.
If I switch to another tab, it steals the focus.
And it's not all that informative, because it seems to not scroll down
whenever something happens.

This is not the behavior of a normal tab in Eclipse.

Does anyone know of a setting somewhere, somehow to make it not do
these things?

using ImageSource from ClientBundle in CSS file

2010-02-10 Thread Tsukasa

Hi,

I'm trying to get some modular app desgin working using GWT and MVP.
But now I'm stuck in some ClientBundle issue.

I wanted to create a ClientBundle for my header widget which contains
the CSS information and image resources. CSS definitions should be
stored in a seperate file called header.css and after working with the
Developers Guide - UiBinder I tried the following approach:

public interface Resource extends ClientBundle {
public interface HeaderCss extends CssResource{
public String headerBanner();
public String menuItem ();
public String selected ();
public String hovered();
public String langswitch();
public String nav();
}

@Source(header.css)
public HeaderCss css();

@Source(header_bg.png)
public ImageResource headerBackground();
}

this interface is included into header.ui.xml by:
ui:style src=resource/header.css
type=appgui.client.ui.widgets.header.resource.Resource.HeaderCss/

I now want to know how to include ImageResource headerBackground(); in
my header.css
I tried to do this by using the @sprite annotation as described in GWT
CSS CookBook (referenced by
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/f3ba1d8dfc9d67f8/b5bf0790aca915ea?lnk=gstq=cssresource#b5bf0790aca915ea)
but i couldn't get it working. GWT plugin in eclipse announces
[ERROR] [appgui] Unable to find ImageResource method
value(headerBackground) in
appgui.client.ui.widgets.header.Header_HeaderUiBinderImpl_GenBundle :
Could not find no-arg method named headerBackground in type
appgui.client.ui.widgets.header.Header_HeaderUiBinderImpl_GenBundle

My Header class is set up in the way Developer Guide describes:

public class Header extends Composite {

private static HeaderUiBinder uiBinder =
GWT.create(HeaderUiBinder.class);

interface HeaderUiBinder extends UiBinderWidget, Header {
}

@UiField
HeaderCss style;

...

public Header(String firstName) {
initWidget(uiBinder.createAndBindUi(this));


}

...
}

header.css:
@sprite .headerBanner {
gwt-image: 'headerBackground';
height: 100px;
width: 100%;
margin: 0px;
}

I think my current Problem is, that I have missunderstood the usage of
either @sprite or the ClientBundle or both.

Re: TreeMapString, ListInterface_For_Custom_Pojo can not be serialized by gwt-rpc in gwt 2.0

2010-02-10 Thread István Szoboszlai

Hello David!

I don't think it is a bug. How would the gwt compiler know that you want to
transfer Pojo_Object_Concrete_Class over RPC. You only declare
Custom_Pojo_Object_Interface in your RPC interface. You have to explicitly
show the compiler what classes you want to transfer over RPC.

I hope this helps

 in fact i tried mixing GWT, Isomorphic SmartGWT and CometServlet.
 I have one main GWT Project and a couple of java projects to create

 i use smartgwt for the user interface and gwt for the client server

 in fact i´m not absolutely clear if my problems are caused by
 compiling the gwt or the smartgwt parts.

 but as soon as i can localize the code that causes the problems i will

  Are you trying to run this under an external app server (e.g. Tomcat), or
  have you simply changed the port that the embedded server uses? If you're
  deploying your app to an external app server, I can see how you might end
 up
  with an application/application path (although I don't know how correct
 it
  would be).
 
  Let's take a step back, can you describe the directory structure that you
  see after you run the GWT compiler?
 
 
 
   i think the gwt compiler has a problem with it´s pathes and the
   folders within the war file.
   i have a new problem, when i compile the application and start it at
   the application server all pathes to the images folder are wrong, but
   this time the name of the application instance is missing in the image
   pathes.
 
   i´m absolutely sure both problems had nothing to do with the upgrade
   but are compiler errors. i had similar problems before when ich made
   an if statement on an Tree.
 
   my original code was something like:
   if ( tree != null )
 
   that caused compiler error that have not been displayed but the
   XYZ.cache.js couldn´t been found
 
   wehn ich changed the line to:
   if ( tree.getRoot() != null )
 
   the compiled code worked.
 
  I was able to successfully run the following code in both Development and
  Web mode:
 
  public class Test implements EntryPoint {
 
public void onModuleLoad() {
  Tree t = new Tree();
  TreeItem ti = null;
 
  if (ti != null) {
 
  }
  else {
ti = new TreeItem(hello there);
  }
 
  t.addItem(ti);
  RootPanel.get().add(t);
}
 
  }
 
  Is there something different between your app and the above snippet?
 
  So i guess, you google folks have to do a coulpe of fixes to your
 
   compiler :-)
 
  I think several, mutually exclusive issues are being confused here. Would
  you mind sending me your project, or a sample project that reproduces the
  issues you mention above?

There are no settings for controlling its behavior at this time. It
basically works like a console view in Eclipse. It won't auto-scroll in
general, but it should focus you on the first error/warning in the log. How
many log entries are showing up for you? What is your log level set to?

 There are two possibilities: inheriting DialogBox or having a

Re: IncompatibleRemoteServiceException with -noserver argument in gwt 2.0

2010-02-10 Thread denis56

Thanks a lot for your help.

I figured out that you need to deploy in exploded war when using an
external server, since on every start and page refresh DevMode would
generate a new rpc policy file in my project which was actually
missing in the war on the server and since the problem.

On 28 Jan., 17:02, Rajeev Dayal rda...@google.com wrote:
Hi,

If you want to pick up changes to your server code while the development
server is running, you need to deploy your application in exploded-war
format to JBoss.

When you run GWT in -noserver mode, you should point your -war directory
over to your JBoss server's deployment directory - that way, any files
generated by GWT will be dumped into your running server's directory.

Unfortunately, there is a bug in GWT's RPC system that will prevent the
server from picking up changes to the RPC serialization policy file, even if
you copy the modified serialization file into the running server's
deployment directory:

http://code.google.com/p/google-web-toolkit/issues/detail?id=4548

I'd recommend that you star this issue if you want it to be prioritized.

for a while and was able to find a clumsy workaround. Could anyone
please suggest a solution in the following case as I believe it may
be either my configuration error or gwt bug.

Here is a sample project structure to refer to:
- java
- modules
| -- gwtclient

There is an ant task that compiles gwt code and puts it generated code
under modules/gwtclient, this folder is than zipped as war file and
deployed to jboss. It all runs then smoothly in a browser.

However should I start DevMode with -noserver option and the -war
option pointing at NOT PACKAGED directory modules/gwtclient in the
project structure, the following exception
com.google.gwt.user.client.rpc.IncompatibleRemoteServiceException:
Type 'XYZ' was not assignable to
'com.google.gwt.user.client.rpc.IsSerializable' and did not have a
custom field serializer. For security purposes, this type will not be
deserialized.
will be thrown.
I noticed that on every start DevMode creates new .gwt.rpc file under
modules/gwtclient (and not to deployed war) and that the exception
disappears if the modules/gwtclient is packaged and redeployed as
DevMode runs.

From
http://groups.google.com/group/google-web-toolkit/browse_thread/threa...
I understand that the server (jboss' tomcat?) cannot find
suitable .gwt.rpc file and falls back to LegacySerializationPolicy
which demands IsSerializable interface.

Shouldn't DevMode running with -noserver argument be able create
new .gwt.prc files direct in the war file deployed to jboss or not
create it at all?
Is this a bug or my DevMode configuration mistake?

Thanks

XMLParser Help

2010-02-10 Thread Russ

Hi,
Could someone point me to an example (or tutorial) of how to retrieve,
parse and display data from a reomte XML doc?

I've tried numerous examples from the web with no luck. This time I'd
like to try GWT's XMLParser.

Thank you,
-Russ

Re: How to use g:DialogBox UIBinder definition from Java

2010-02-10 Thread Stefano Ciccarelli

Sorry, I was talking about Thomas Broyer solution #1.
Your code (pastebin) is what I was already doing.

BTW this is the .java:

public final class AboutDialogDisplay {
@Inject
private AboutDialogDisplay() {
uiBinder.createAndBindUi(this);
}

@UiFactory
DialogBox thatsJustMe() {
return this;
}
}

And this is the .ui.xml:
g:DialogBox animationEnabled=true glassEnabled=true modal=true
..
/g:DialogBox

Thanks
Stefano

Re: How to use g:DialogBox UIBinder definition from Java

In your code, for solution #1, you need to extends DialogBox, you forgot

For my solution, I only encapsulate DialogBox within an HTMLPanel an then I
added two public function for showing and hiding my dialogbox. (Solution #2)

I'm already doing like you, but I'd like to try the solution #1 explained by
Thomas Broyer, so the code is from that test. The class already extends
DialogBox and I get the error reported, the extends is missing because I
done something wrong with cutpaste.
I need @Inject because that class is the Display injected in a Presenter.

I want to try that solution because I prefer to extends DialogBox.

If you want to map the XML to model classes you can take a look at

take data from the XML and inject it into your model classes.

Deploying to jboss

In the older versions of GWT I created build.xml scripts and ran ant to

Do I still have to do this with the new (2.0) architecture?  I tried copying
the war directory (generated by eclipse plugins for compilation) into
jboss/server/default/deploy/project but I got errors.  My project runs
fine in the embedded jetty server.

Is there a simple script or command I can execute to do this?  My project is

GWT enum comparison

2010-02-10 Thread bconoly

Hello All,
I have an enum in which I'm trying to use it's natural ordering.
In the javadocs for the java enum I get that it's based on the order
the enum constants are declared so if I declare an animal enum as:

DOG,
CAT;

then using DOG.compareTo(CAT) will tell me that dog comes before cat.
Where if i declare them as:

CAT,
DOG;

then using DOG.compareTo(CAT) will tell me that cat comes before dog.

My question is, Does the GWT compiled version of Java's Enum support
this same feature?

Thanks in advance


JAVADOC FOR REFERENCE:
public final int compareTo(E o)

Compares this enum with the specified object for order. Returns a
negative integer, zero, or a positive integer as this object is less
than, equal to, or greater than the specified object. Enum constants
are only comparable to other enum constants of the same enum type. The
natural order implemented by this method is the order in which the
constants are declared.

Specified by:
compareTo in interface ComparableE extends EnumE

Parameters:
o - the object to be compared.
Returns:
a negative integer, zero, or a positive integer as this object
is less than, equal to, or greater than the specified object.

Re: XMLParser Help

In the server impl file:

@Override

*public* String getMapURL(String theURL) {

URL url = *null*;

String s = *null*;

String retstr = ;

*try* {

url = *new* URL(theURL);

BufferedReader reader = *new*
BufferedReader(*new*InputStreamReader(url.openStream()));

*while* ((s = reader.readLine()) != *null*) {

retstr += s + \n;

}

*return* retstr;

} *catch* (MalformedURLException e) {

e.printStackTrace();

} *catch* (IOException e) {

e.printStackTrace();

}

*return* retstr;

}

}

Call from the client with the name of the URL that you want.

On  the client side, you can parse with stuff similar to this:


*protected* MapWidget createMapWidget(String mapString, *int* width,
*int*height, TextArea ta) {

Document doc = XMLParser.*parse*(mapString);

Element root = doc.getDocumentElement();

NodeList tempNodes = root.getElementsByTagName(temp);

String s = *new* String();

AreaWidget[] areas = *new* AreaWidget[tempNodes.getLength()];

*for* (*int* i=0; itempNodes.getLength(); i++) {

Element tempElement = (Element) tempNodes.item(i);

String theTemp = getElementText(tempElement, number);

String theDescription = getElementText(tempElement, description);

String theXStart = getElementText(tempElement, xstart);

theXStart = String.*valueOf*(Math.*round*(Float.*parseFloat*(theXStart) *
width));

String theXStop = getElementText(tempElement, xstop);

theXStop = String.*valueOf*(Math.*round*(Float.*parseFloat*(theXStop) *
width));

String theYStart = getElementText(tempElement, ystart);

theYStart = String.*valueOf*(Math.*round*(Float.*parseFloat*(theYStart) *
height));

String theYStop = getElementText(tempElement, ystop);

theYStop = String.*valueOf*(Math.*round*(Float.*parseFloat*(theYStop) *
height));

String theArea = theXStart + , + theYStart + , + theXStop + , +
theYStop;

s += theTemp + \n;

s += theDescription + \n;

s += theXStart += \n;

s += theXStop += \n;

s += theYStart += \n;

s += theYStop += \n;

s += theArea += \n;

areas[i] = *new* AreaWidget(rect, theArea, theTemp,
*new*SolarSystemCommand(theTemp));

}

ta.setText(s);

MapWidget map = *new* MapWidget(areas);

*return* map;

}

*private* String getElementText( Element item, String value) {

String result = ;

NodeList itemList = item.getElementsByTagName(value);

*if* (itemList.getLength()  0  itemList.item(0).hasChildNodes()) {

result = itemList.item(0).getFirstChild().getNodeValue();

}

*return* result;

}


In this example, I am parsing an XML file that describes an image map to be
applied to a jpg which I retrieve.

The XML contains entries like this:


temperatures

temp

number044/number

descriptionTest *Temp* Sensor OTA 4,3: TTS(4,3)/description

xstart0.508/xstart

xstop0.566/xstop

ystart0.477/ystart

ystop0.532/ystop

/temp

temp

number081/number

descriptionTest *Temp* Sensor OTA 7,5: TTS(7,5)/description

xstart0.731/xstart

xstop0.795/xstop

ystart0.332/ystart

ystop0.387/ystop

/temp

temp

number066/number

descriptionTest *Temp* Sensor OTA 3,1: TTS(3,1)/description

xstart0.434/xstart

xstop0.496/xstop

ystart0.622/ystart

ystop0.685/ystop

/temp
.

/temperatures

The rectangles are percentages offsets from the top left corner of the image
(values range between 0 and 1)... by multiplying by the size of the image
(width and height) you can create an image map.

copypaste and TextBox

2010-02-10 Thread seven.reeds

Hi,

Which of the gwt 2.0 style event Handlers recognize pasting text into
a TextBox?  I have ChangeHandler, KeyUpHandler and MouseUpHandlers
installed on a TextBox but no joy.

I am trying to accomplish the following: I have a TextBox group
together with a button.  In the start state the TextBox is empty and
the button is disabled.  If I type in the box the KeyUpHandler seems
to know this and I can enable the button if the value is what I think
it should be.  I have yet to find the magic for using the mouse to
paste text into the box and have that trigger the enable-button
condition.

ideas?

Re: How to get unpublished events from a SuggestBox?

2010-02-10 Thread phb

Okay, as I think about it, this approach won't work anyway, because I
don't want to change the drop down menu here.  I only want to fill in
the suggestion textbox, like the Google suggestbox does.  So short of
cloning the class and all its support (yuck) I guess this ends up
being a feature request for the base class.  It's a tiny change to the
underlying code, but I can't see a way to create the effect from the
outside.

Still very curious about why the suggestbox wasn't seeing my event
though.  I even tried suggestBox.fireEvent() on it, and it seemed to
have no effect.  Anybody know how to do this right?

Re: copypaste and TextBox

2010-02-10 Thread seven.reeds

Ok, yikes.  I created the following tiny sample to try and find out
which events fire when.

I did have a handler for *every* possible TextBox event but the mouse
over and move events just flooded everything -- I removed those.

Now I load the test.  I select some text that is outside of the text
box and move the cursor to the text box.  I click in the textbox to
gain focus and the event flooding starts again.  I click to paste-in
the copied text and more event flooding happens but no text is
actually pasted.

I will keep pruning down on event handlers.

Re: Get data of widgets in a Panel or dynamically determine their class

2010-02-10 Thread Sudeep S

you can try checking widget.isAttached on all the widgets.

the one widget that is added will return you a true.

now that you know the widget you can retrieve the data entered.

hope it helps

 Hi all,
  I'm dynamically adding different widgets (TextBox, CheckBox or
 TextArea) to a Panel, depending on the columns found in an SQL table.
 Once the different fields are filled up by the user and the Save
 button is clicked, the code must collect all the introduced data and
 send it to server side.
  The problem I have is: How do I access data on every widget without
 knowing what class is each one? That is, I can have access to any
 widget in the Panel, using the getWidget method:
 myPanel.getWidget(i)
  But how do I access data? I've tried something like
 TextBox myWidget;
 myWidget = (TextBox) myPanel.getWidget(i);
 String data = myWidget.getText();
  But this generates an exception if the Widget is of type CheckBox,
 because it cannot be cast to TextBox class.
  If I could determine the class of myPanel.getWidget(i), then I would
 use some if's to cast that to whatever class it's needed.

 Thanks

Does Image not serialize? How to transfer image back to client?

2010-02-10 Thread Ralf B

Hello everybody,

I am new to GWT and want to have a service that transfers an Image
object (com.google.gwt.user.client.ui.Image) back to the client.
(Using GWT 2.0.0 with Eclipse Galileo and Eclipse GWT plugin).

On the client, I have the following service method:

import com.google.gwt.user.client.ui.Image;
Image getImage();

and the following service async method:

import com.google.gwt.user.client.ui.Image;
void getImage(AsyncCallbackImage callback);


On the server, I have the following service implementation:


import com.google.gwt.user.client.ui.Image;
@Override
public Image getEventTimeline() {

// 1) code to generate image from data

// 2) create new image and return to client
   Image image = new Image(test.png);
return image;
}

When I compile the code, I get the following error:

[ERROR] com.google.gwt.user.client.ui.Image is not assignable to
'com.google.gwt.user.client.rpc.IsSerializable' or
'java.io.Serializable' nor does it have a custom field serializer
(reached via com.google.gwt.user.client.ui.Image)
  [ERROR] com.google.gwt.user.client.ui.Image has no
available instantiable subtypes. (reached via
com.google.gwt.user.client.ui.Image)

'com.google.gwt.user.client.rpc.IsSerializable' or
'java.io.Serializable' nor does it have a custom field serializer
(reached via com.google.gwt.user.client.ui.Image)

This suggests that an Image cannot be serialized. I have two questions
about this:

1) Isn't every Google object serializable  by default. Otherwise, what
is the point of having a separate image class in GWT?

2) What is the proper way of doing this? I want to create the image
server-sided every time a user clicks a button and return it back to
the user where it is supposed to be displayed in a panel.

Any suggestions?

Thanks a lot,

How to define and read Global JavaScript Variable in GWT

2010-02-10 Thread Ashish Khivesara

Is there a way to define a global javascript variable in GWT?
I was able to define one in a sample.js file and then read the same using a
JSNI native method.
But was wondering if there is a way to this purely in Java (GWT) .

My goal is to be able to have a global object that can be shared between
multiple gwt apps which are modules inside the same project.

Re: How to declare dependent style names with UiBinder

I'm facing a similar problem. Is there any UIBinder team members on

 I want to control the background color of this textarea for writeable

 achieve this. So I try this:

 !DOCTYPE ui:UiBinderSYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;

         .textBoxStyle-readonly {
             background-color:lightgray;
         }
     /ui:style

     g:TextArea styleName={style.textBoxStyle} visibleLines=3 /
 /ui:UiBinder

 Obviously this won't work becausestylenames are obfuscated for
 CssResources resulting in something like this:

 .G1x26wpeN {
     background-color:yellow
  }
 .G1x26wpeO {
     background-color: lightgray;

 }

 The result HTML for writeable textarea looks like this:

 textarea tabindex=0 class=G1x26wpeN rows=3/

 The read only textarea looks like this:

 textarea tabindex=0 class=G1x26wpeN G1x26wpeN-readonly
 readonly= rows=3/

 How do I declare thestyleso GWT will obfuscate the primary part but
 not the -readonly decdorator?

 I know that I can disable the obfuscation for the entirestylename.
 But I'd like to keep the obfuscation while making use of the
 decorators.

The trick I have used is to encode the image in Base64, and then send the

 ... make the image  ( a spiral dither pattern) and save to disk

Re: Problem with Thread in GWT2.0

Thanks a lot for you all I currently stopped at timer's solution -
just for quickly gett the working app, and further I planned to use
GWTeventservice library - it's a very useful feature.

 If I understood truly this code may help to solve your problem. This
 is getting an integer result from server 8 times in time interval 800

Re: copypaste and TextBox

Try it like this:

import com.google.gwt.user.client.Event;
import com.google.gwt.user.client.ui.Button;

final Button sendButton = new Button(Send);
sendButton.setEnabled(false);
final TextBox nameField = new TextBox()

}
};
nameField.sinkEvents(0x7fff);
RootPanel.get(nameFieldContainer).add(nameField);

Re: Read XML file on server using ServletContext.getResource() never works for me

2010-02-10 Thread Lucas86

Unfortunately that doesn't get results that are any better. What's the
configuration that you're referring to? I just use the following

public class DataServiceImpl extends RemoteServiceServlet implements
DataService {
  public String getData() {
ServletContext context = getServletContext();
ServletContext context = getServletContext();
InputStream t1, t2, t3, t4, t5, t6, t7;
InputStream isr;
InputStream stream;
String paths = Dummy start value;
try {
//This is lifted straight from the google groups 
answer, what is
the configuration?
//Tried on 2/10, all of these get null too
stream = getServletContext().getResourceAsStream(/);
paths = context.getResourcePaths(/).toString(); 
//Gets: /, /
MyApp.css, /MyApp.html, /WEB-INF/...
isr = context.getResourceAsStream(/);
t1 = context.getResourceAsStream(/MyApp.css);
t2 = context.getResourceAsStream(/MyApp.html);
t3 = context.getResourceAsStream(MyApp.css);
t4 = context.getResourceAsStream(MyApp.html);
t5 = context.getResourceAsStream(/WEB-INF/);
t6 = context.getResourceAsStream(WEB-INF/);
t7 = context.getResourceAsStream(WEB-INF);
} catch (Exception e) {
System.out.println(Problem!);
}
  }
}

Am I doing something wrong in how I get the context? I could
understand if I was doing something totally wrong, but again, the
getPaths call lists exactly what I expect. I'm also working on a Mac,
if anyone's heard of that making any difference. Thanks again.

 My understanding is faulty.

 The final keword gave me grief so I moved the button and textbox

 triggered.  I am using GWT 2.0, eclipse 3.5 with the GWT plugin.  I am
 on the most recent or a very recent Ubuntu box and am displaying this
 test in a firefox 3.5.7 browser.

 So, the app starts with an empty textbox and disabled button.  I use
 the mouse to select some text and then either I:

 - move the mouse to the textbox and just paste or

 - move the mouse to the textbox, click the textbox and then paste

 In either case onBrowserEvent is not triggered... as far as I can tell.

 After the paste, if I click outside the textbox then I get a change
 event alert message from onBrowserEvent.

 The new test is:

 public class Test implements EntryPoint {

         Button sendButton = new Button(Send);
         TextBox nameField = null;

         public void onModuleLoad() {
                 nameField = new TextBox() {

JBOSS deployment from GWT Eclipse projects

Okay, this is ulitmately easy...

Step 1. Recursively copy your war directory to project.war in
jboss/server/default/deploy

You HAVE to name it with the .war or JBOSS becomes TERRIBLY confused.

Step 2. For some reason, database connectivity (for me, at least) broke in
JBOSS.  I needed to copy mysql-connector-java-3.0.17-ga-bin.jar into
jboss/server/lib

This lets JBOSS see the database connectivity in a way it understands.  I
don't understand, but hey, it works.  Of course, if you use Oracle you'll
probably copy a different file..


I hope that this saves someone time in case they have to do it themselves.

Oh, when you start your project don't set it up as for GAE (Google App
Engine)... I think this might cause problems.

 Still very curious about why the suggestbox wasn't seeing my event

Re: Any Google Wave developers in this group?

Sky, maybe you should check again :)

I have just released WaveConnector - a turnkey solution for developing
wave gadgets using GWT and testing them in hosted mode. Please head
over to my blog at http://thezukunft.com or the project page at
http://code.google.com/p/waveconnector-gwt/ for details. Developing a
Wave Gadget is as easy
as downloading a zip archive :D

Also, there are some people on the Wave Dev group that would also be
interested in a Wave+GWT group. I think I'll try to start something
like that tomorrow. (and then I won't have to cross-post as much,
sorry for that)

 Hi guys,

 I am about to publish my own mock implementation of the Wave API for

that's the problem you are missing the ?gwt.codesvr=localhost:9997

also if you don't have ?gwt.codesvr=localhost:9997 on the url, you

Re: using ImageSource from ClientBundle in CSS file

 Hi,

 I'm trying to get some modular app desgin working using GWT and MVP.
 But now I'm stuck in some ClientBundle issue.

 I wanted to create a ClientBundle for my header widget which contains
 the CSS information and image resources. CSS definitions should be
 stored in a seperate file called header.css and after working with the
 Developers Guide - UiBinder I tried the following approach:

 public interface Resource extends ClientBundle {
         public interface HeaderCss extends CssResource{
                 public String headerBanner();
                 public String menuItem ();
                 public String selected ();
                 public String hovered();
                 public String langswitch();
                 public String nav();
         }

         @Source(header.css)
         public HeaderCss css();

         @Source(header_bg.png)
         public ImageResource headerBackground();

 }

 this interface is included into header.ui.xml by:
         ui:style src=resource/header.css
 type=appgui.client.ui.widgets.header.resource.Resource.HeaderCss/

 I now want to know how to include ImageResource headerBackground(); in
 my header.css

AFAICT, you can only use ui:image within ui:style, because
UiBinder will create a ClientBundle for the ui.xml, and you can
(AFAIK) only use an ImageResource that is in the same ClientBundle as
your CssResource.

[gwt-contrib] Re: RFC: sharded linking

2010-02-10 Thread Alex Moffat

I've replied before but don't see it here, if it turns up ignore this
dupe.

I don't maintain any linkers but I have experimented with multi-
machine builds. The current Precompile, CompilePerms, and Link
implementation has the nice feature that the CompilePerms step does
not require access to the source code being compiled. This makes it
very, very much easier to deploy additional CompilePerms workers as
they don't need to check out source code etc. I like the plan for
being able to perform some linking in parallel but I wouldn't like to
lose the ability to deploy a useful CompilePerms worker that does not
need source code access. If performing Java parsing, creating AST and
generating artifacts is something that may need to be parallelized for
some builds then I'd like it if that was done in an additional step so
that people could choose whether or not to run that on multiple
machines while still being able to run the CompilePerms steps on
multiple machines.

On Feb 9, 4:31 pm, Lex Spoon sp...@google.com wrote:
 This is a design doc about speeding up the link phase of GWT.  If you don't

 sure your linker can be updated with the proposed changes.  If you do have a
 multi-machine build, or if you have some ideas about them, then perhaps you
 can help us get the best speed benefit possible out of this.

 I want to speed up linking for multi-machine builds in two ways:

 1. Allow more parts of linking to run in parallel.  In particular, anything
 that happens once per permutation and does not need information from other
 permutations can run in parallel.  As an example, the iframe linker chunks
 the JavaScript of each permutation into multiple script tags.  That work
 can happen in parallel once the linker API supports it.

 2. Link does a lot of Java serialization for its artifacts, but the majority
 of the artifacts in a compile are emitted artifacts that have no structure.
  They are just a named bag of bits, from the compiler's perspective.  It
 would help if such artifacts did not need a round of Java serialization on
 the Link node and could instead be bulk copied.

 === Transition ===

 The compiler will support two compilation modes: maximal sharding and
 simulated sharding.  Maximal sharding is used when all linkers support it
 and the Precompile/CompilePerms/Link entry points are used.  Simulated
 sharding is used when either some linker can't shard or when the Compiler
 entry point is used.

 Linkers individually indicate whether they implement the sharding or
 non-sharding API. This allows linkers to be updated one by one and to leave
 the non-sharding API behind once they do. It does not cause trouble with
 other linkers, because in practice linkers are highly independent.  I've
 looked at as many linkers as I could find to verify this.  Occasionally one
 linker depends on another; in such a case they'll have to be updated in
 tandem, but the need for that should be rare.

 By default, a linker is assumed to want the legacy non-sharding API. For
 such linkers, it isn't safe to assume it generators or its associated
 artifacts can be safely serialized and then deserialized on a different
 computer.

 The non-sharding API will be deprecated.  After the sharding API has been
 out for one GWT release cycle, support for non-shardable linkers will be
 dropped.

 === Maximal sharding ===

 Currently, Precompile parses Java into ASTs and runs
 generators. CompilePerms then runs one copy for each permutation, in
 parallel. Each instance optimizes the AST for one permutation and then
 converts it into JavaScript plus some additional artifacts. Finally, Link
 takes the JavaScript and all the produced artifacts, runs the individual
 linkers, and produces the final output. In summary, the three stages are:

 current Precompile:

    - parse Java and run generators
    - output: number of permutations, AST, generated artifacts

 current CompilePerms:

    - input: permutation id, AST
    - compile one permutation to JavaScript
    - output: JavaScript, generated artifacts

 current Link:

    - input: JavaScript from all permutations, generated artifacts
    - run linkers on all artifacts
    - emit EmittedArtifacts into the final output

 With maximal sharding, Precompile does no work except to count the number of
 permutations. Each CompilePerms instance parses Java ASTs, run generators,
 and optimizes for a specific permutation. Additionally,
 each CompilePerms instance also runs the shardable part of linkers on the
 results for that permutation. It then thins the artifacts (see below) and
 emits them. Finally, Link takes these results from the CompilePerms
 instances, runs the final, non-shardable part of each linker, and emits all
 the artifacts designated as emitted artifacts.  In summary, the
 maximal-sharding staging looks like this:

   We can't transfer handlers because the HandlerRegistrations are linked

  Why would I expect that? I'd use such a call expecting it to allow me to
  swap different sets of handlers around, e.g. a widget that has two very
  different modes (edit v. nav).

   Also, we've been trying to move to a model where we add Event Handlers
   in a widget's constructor instead of overriding onBrowserEvent(). Those
   handlers will be lost when we switch to a new HandlerManager, unless we
   unregister the old ones and register new ones.  That complicates the
   widget creation process.

  I hope you mean add event handling capabilities at constructor time, not
  actual handler instances. If you mean the latter, that's a dreadful idea.

  I still don't buy this argument. If I swap it out, I can swap it in.

   If we require that the user specify the one and only HandlerManager when
   the first handler is added, then we avoid these problems.

  I really think this is over protective, and the kind of thing that makes our
  widgets too hard to customize.

[gwt-contrib] Re: RFC: sharded linking

2010-02-10 Thread Alex Moffat

I may have misunderstood the proposal but I've experimented a little
with multi machine builds so I'll comment based on that.

One very nice feature of the current system is that the CompilePerms
step does not need access to the source code being compiled. This is a
significant benefit as it makes it very easy to setup a new machine to
perform CompilePerms work. Without this each CompilePerms machine
would have to checkout the source to compile, a significant amount of
work and potentially difficult to configure. My experiments showed
most of the time being spent in the current Precompile step, but that
is because I was not generating a large number of permutations. I
imagine the use case for multi machine builds is that you're doing a
build for QA or release that needs to include all languages etc,
certainly 10s of permutations. One big machine with access to the
source to run Precompile in parallel on multiple pages and then being
able to simply make available lots of dumb CompilePerms workers that
need just GWT installed would be a big advantage here. Or, Precompile
different pages on different machines (using some out of band
distribution system) and then use a farm of dumb workers to
CompilePerms. Individual developers probably use dev mode or just
build a single language.

 Making it possible to run portions of the linkers as part of
CompilePerms would certainly be a benefit and I'm all for the reduced
serialization plan.

 and the Precompile/CompilePerms/Link entry points are used.  Simulated
 sharding is used when either some linker can't shard or when the Compiler
 entry point is used.

 Linkers individually indicate whether they implement the sharding or
 non-sharding API. This allows linkers to be updated one by one and to leave
 the non-sharding API behind once they do. It does not cause trouble with
 other linkers, because in practice linkers are highly independent.  I've
 looked at as many linkers as I could find to verify this.  Occasionally one
 linker depends on another; in such a case they'll have to be updated in
 tandem, but the need for that should be rare.

 By default, a linker is assumed to want the legacy non-sharding API. For
 such linkers, it isn't safe to assume it generators or its associated
 artifacts can be safely serialized and then deserialized on a different
 computer.

 The non-sharding API will be deprecated.  After the sharding API has been
 out for one GWT release cycle, support for non-shardable linkers will be
 dropped.

 === Maximal sharding ===

 Currently, Precompile parses Java into ASTs and runs
 generators. CompilePerms then runs one copy for each permutation, in
 parallel. Each instance optimizes the AST for one permutation and then
 converts it into JavaScript plus some additional artifacts. Finally, Link
 takes the JavaScript and all the produced artifacts, runs the individual
 linkers, and produces the final output. In summary, the three stages are:

 current Precompile:

    - parse Java and run generators
    - output: number of permutations, AST, generated artifacts

 current CompilePerms:

    - input: permutation id, AST
    - compile one permutation to JavaScript
    - output: JavaScript, generated artifacts

 current Link:

    - input: JavaScript from all permutations, generated artifacts
    - run linkers on all artifacts
    - emit EmittedArtifacts into the final output

 With maximal sharding, Precompile does no work except to count the number of
 permutations. Each CompilePerms instance parses Java ASTs, run generators,

This check will in most cases not be needed. However GWT is doing this
check also on the other cases where it is accessing the __listener
attribute (DOMImplStandard for example). When you create the
RichTextAreaImpl in module one and a second module sets up the attribute
on the iframe element, you will need this check (you should normally not
od that).

If you think we should not do this safty check, we can remove it here.

Description:
At the moment you cannot use the RichTextAreaImpl class without the
Widget class. If you have a custom class that implements the
EventListener interface and sets up the __listener attribute that gets
used with the RichTextAreaImpl you will get an execption. This patch
changes the RichTextAreaImpl classes to not be coupled to Widget but be
bound to the EventListener interface.

It also decouples it from the RichTextArea class. The only reason the
RichTextArea is linked is because of the initialize event.

With this changes you are able to use the wonderful RichTextAreaImpl
classes in any custom EventListener and any custom class that implements
HasInitializeHandlers.

Sebastian,

Sorry it's taken so long for anyone to respond. This sounds like useful
functionality, and I would suggest creating an issue (
http://code.google.com/p/google-web-toolkit/issues/) and a patch for public

easier for people to try out your patch and refine it.

 Hello,

 I was missing the ability to format a block with h1 - h6 tags. I
 researched the topic and build a patch which allows to insert block
 tags. It makes use of the FormatBlock command.

 I would like to ask, if you are interested in the patch and discuss
 the coding decision I took.

 1)
 I couldn't find any guidance on testing. I have tested with Safari 4,
 Firefox 3.5, IE 6, IE 8 and IE 8 in IE 7 mode.

 2)
 Currently only the tags h1 to h6, pre, address and p work
 stable across browsers. To limit the choice of tags, I have created an
 enum to limit the possible values.

 public static enum BlockTag {
H1, H2, H3, H4, H5, H6, PRE, ADDRESS, P;
  final String OPEN = ;
  final String CLOSE = ;
  public String toTag() {
return OPEN+name()+CLOSE;
  }
}

 The advantage is that you cannot provide the wrong tags. The
 disadvantage is that you cannot provide tags which are for example
 supported in newer browser versions.

 The rest of the tag is just a new method in RichTextAreaImplStd.
  public void formatBlock(RichTextArea.BlockTag blockTag) {
execCommand(FormatBlock, blockTag.toTag());
  }

 Shall I leave it that way or turn it into a String parameter?

 3)
 Should I create a bug tracking entry for this?

 If somebody is interested, here are some links, I found interesting
 while exploring the topic.

Sven, you're arguing both sides here. You want things to be more
customizable in general, but with your specific patch you're trying to be as
restrictive as you can to achieve your personal goal.

I'm assuming that if we provide an unrestricted setHandlerManager we would
also provide a getHandlerManager. It doesn't seem like rocket science to
expect someone to check for an existing one if before clobbering it. I'm
also assuming that these methods are protected, not part of every widget's
public api.

I also would argue against providing both createHM and setHM. Redundant API
is confusing API, another unfortunate trait of our widget set. Lazy creation
can happen in the default implementation of getHM. A custom widget author
could override that method to maintain laziness, or call setHM from their
constructor to keep ours from ever seeing the light of day.

Re: [gwt-contrib] Re: RFC: sharded linking

2010-02-10 Thread Lex Spoon

What you describe, Alex, is available via the Compiler entry point, though
it hasn't been particularly well documented.  There is a
PermutationWorkerFactory that can create CompilePerms workers.  The default
worker factory spawns Java VMs on the same machine, but it is possible to
write a replacement worker that uses ssh or whatnot to do the work on a
separate machine.  The way to plug in a replacement worker factory is to set
the Java property gwt.jjs.permutationWorkerFactory .


That said, I thought the reason for existence of Precompile, CompilePerms,
and Link is to get the best build time but at the expense of needing extra
configuration.  We are finding that by spending a few seconds copying source
code over, we save 10+ minutes in Precompile and 10+ minutes in Link.

Is copying source code so inconvenient that it would be worth having a
slower build?  I would have thought any of the following would work to move
source code from one machine to another:

1. rsync
2. jar + scp
3. svn up on the slave machines

Do any of those seem practical for your situation, Alex?

Overall, it's easy to provide an extra build staging as an option, but we
support a number of build stagings already

Another option to achieve this with potentially less danger is to maintain a
stack of HandlerManagers.  If one HM doesn't handle an event, it goes down
to the next one.  Then, if you want to have some modal event handling logic,
you push a new HM on the stack with its own set of event handlers.  When you
are done with the modal logic, you pop it off the stack.  Event types not
handled by the modal event handler fall through to the main one, so in your
example onOpen would still get handled properly.

I still think my proposal solves this for both cases.  We add a protected
createHandlerManager, which is more restrictive because it is only called
once per widget.

We also make getHandlerManager() protected, which allows users to replace
the HandlerManager if they really want to by overriding getHandlerManager to
return one of many.  It would be up to the developer to add a
setHandlerManager() method in their own widgets that would change the return
value of getHandlerManager(), so its intentionally more difficult and
therefore forces the developer to think about it a little more.

What does make it difficult is that you can't have a pool of worker machines
that can build any project that are asked of them without copying the
sources to the worker for each request.  For a large project, this can get
problematic especially when you have to send the transitive dependencies.

Besides, what is gained by having the user have to arrange this copying
themselves rather than the current method of sending it as part of the
compile process?  For example, distributed C/C++ compilers send the
preprocessed source to the worker nodes, so they don't have to have the
source or the same include files, we currently send the AST which is a
representation of the source, etc.

 build?  I would have thought any of the following would work to move source 
 code from one machine to another:
 
 1. rsync
 2. jar + scp
 3. svn up on the slave machines
 
 Do any of those seem practical for your situation, Alex?
 
 Overall, it's easy to provide an extra build staging as an option, but we 
 support a number of build stagings already
 
 What does make it difficult is that you can't have a pool of worker machines 
 that can build any project that are asked of them without copying the sources 
 to the worker for each request.  For a large project, this can get 
 problematic especially when you have to send the transitive dependencies.
 
 Besides, what is gained by having the user have to arrange this copying 
 themselves rather than the current method of sending it as part of the 
 compile process?  For example, distributed C/C++ compilers send the 
 preprocessed source to the worker nodes, so they don't have to have the 
 source or the same include files, we currently send the AST which is a 
 representation of the source, etc.

Re: [gwt-contrib] Re: Add the ability to change the default HandlerManager of a Widget

 We also make getHandlerManager() protected, which allows users to replace
 the HandlerManager if they really want to by overriding getHandlerManager to
 return one of many.  It would be up to the developer to add a
 setHandlerManager() method in their own widgets that would change the return
 value of getHandlerManager(), so its intentionally more difficult and
 therefore forces the developer to think about it a little more.


The javadoc for getHandlerManager would have to say that the result can't be
cached and should be called each time you need one.
