 Now, my initial instinct is to somehow try and determine whether or  not 
 the FlowPanel needs to vertically resize (how do I determine this?  Can it 
 be determined?) and then use DockLayoutPanel.setWidgetSize to perform the 
 resizing manually. 

 
Sounds like a good approach. On the bottom flow panel, you can use 
element.getScrollHeight()http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/dom/client/Element.html#getScrollHeight()
 and 
either getOffsetHeight or getClientHeight(I can't remember, sorry), to 
determine if you need to expand the flow panel. You should check this when 
the window is resized or when an item is added. When the scroll height is 
larger than the offset/client height, use DockLayoutPanel.setWidgetSize to 
resize the panel.

No idea. Seems to me that you should be using an Anchor and ClickHandlers

Re: MenuBar - how can I cause it to wrap?

The MenuBar uses a table, with each item being a table cell. AFAIK, you're 
not going to have any luck getting that to wrap. 

You should be able to check to see if any of the items are flowing out of 
the window and have those move themselves into a More menu item.

Re: How to determine at runtime which permutation is used?

You can use 
GWT.getPermutationStrongName()http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/core/client/GWT.html#getPermutationStrongName()

You can choose to write that to the screen like so
RootPanel.get().add(new Label(GWT.getPermutationStrongName()));

Re: CellList grid

2011-11-07 Thread Danny Kirchmeier

It's a bit of a hack, but since the cell list is just a list of Divs, you 
can use the CSS3 columns (but watch out, IE9 doesn't support this, and only 
the most recent version of opera does)

public void setColumns(int columns) {
if(columns  1) columns = 1;

Style style = cellList.getElement().getStyle();
String cols = String.valueOf(columns);
/* You could used deferred binding here if you weren't lazy */
style.setProperty(MozColumnCount, cols);
style.setProperty(WebkitColumnCount, cols);
style.setProperty(columnCount, cols);
}

public void setColumnPadding(int width) {
if(width  0) width = 0;

Style style = cellList.getElement().getStyle();
style.setProperty(MozColumnGap, width, Style.Unit.PX);
style.setProperty(WebkitColumnGap, width, Style.Unit.PX);
style.setProperty(columnGap, width, Style.Unit.PX);
}

Re: Ok, CssResources and ClientBundle, what am I doing wrong?

2011-11-04 Thread Danny Kirchmeier

Does your Style1.css now say this:

@external .gwt-Button;
.gwt-Button{
background: black;
color: cyan;
}

Don't forget the semicolon at the end of the @external line. I forgot it 
the first few times I used it. It causes no error to be thrown and next 
style to be completely ignored. 

It worked for me, so hopefully that is your issue.

Re: Possible to get HTML from a widget?

2011-11-03 Thread Danny Kirchmeier

Maybe you'll want to be using the GWT 2.4 docs instead of the GWT 1.4 docs 
you seem to have.
http://google-web-toolkit.googlecode.com/svn/javadoc/2.4/index.html

Anyway, from the Widget you can call 
widget.getElement()http://google-web-toolkit.googlecode.com/svn/javadoc/2.4/com/google/gwt/user/client/ui/UIObject.html#getElement()
 and 
from that element you can call 
element.getString()http://google-web-toolkit.googlecode.com/svn/javadoc/2.4/com/google/gwt/dom/client/Element.html#getString(),
 
which will get you the full html, including it's own tag.

Re: can I use Class.forName and newInstance in GWT ?

2010-12-30 Thread Danny Goovaerts

No, you cannot.

Dynamically instantiating classes would invalidate some of the goals
of the GWT compiler.
The GWT compiler builds a javascript application that only contains
code for the actual call graph of your application.
If you would be able to instantiante classes from arbitray Strings, it
cannot determine the call graph anymore.

This is not really a limitation. You can overcome this by using
factories that create instances of a particular class given its name
using a simple string comparison
and GWT.create(). Of course, you need to know all at development time
all the possible classes that you might need to instantiate. If later
you want to add support
for another class, you need to change the code and rebuild. But in
that situation, you probably need to add additional logic to your app
anyway.
Unless of course your app is completely dynamic, but in that case you
should ask yourself the question if GWT is the technology to use.

Regards,

Danny

Re: Ecryption best practices (server side, client side, password handling)?

2010-08-02 Thread Danny Goovaerts

Stefan has allready made some very good comments so I'm not going to
repeat them.
Some more additional thoughts.

Regarding encrypting the data in the database. If a user does not
trust you (yourself and any of the people that have access to your
server) to look at his data in the database,
why would he trust you when you make the claim that his data is
encrypted in the database? Furthermore, encrypting the data precludes
providing any form of application
level support to your users. Unless your service is exactly providing
extremely secure storage of confidential data, I dont' see any reason
for encrypting the data in the database and in that case you should
find some security experts to assist you.
This of course does not mean that you should not take precautions
against data being accessed by unauthorized people or data being
disclosed. But that falls
under traditional secure server deployment.

I'm afraid that there is no easy and proven solution to protect the
confidentiality and integrity of  Internet based communication without
https. The SSL//TLS protocols have been scrutinized by security
experts. Unless you are such an expert, don't
think that you can come up with something that is solid enough. I
personally would not trust any security measure that has not been
published and analysed by the security and encryption community.

 Hi Sven,

 i did have similar thought in the past.
 Encrypting the database base would solve any Datenschutz data
 protection topic since the application provider would not be able to
 even read the data of his customers.
 However, I do not see any easy solution, yet. Just encrypting any
 database data would destroy any orderings on indexes.
 It would work when only using equivalence, but this is a hard limit.

 The point of encryption should be the server.
 When you doing encryption on client side you must offer the encryption
 and decryption algo, too.
 So it is likely to loose more than to win. (And it is difficult to
 implement encryption without having an integral data type as it is the
 case with javascript).

 To hash the password on client side is equivalent as to put the
 password in clear to the database.
 You loose security when doing so. Any attacker would just send the
 encrypted password, may be to a similar service using the same
 approach!

 Any attacker could substitude the browser and code when he has a legal
 access to the service.
 So he can get the encryption algo and apply it to other users.

 The only thing which is under your control is the server.

  Dear group,

  I want to extend a GWT/GAE application by offering the option to
  encrypt information entered by the user on client side in the
  database. The goal is to increase trust when storing potentially
  sensitive data, e.g. to prevent that people who have access to the DB
  (like me) have read access to the stored information.

  For client-side encryption using GWT I found this 
  post:http://www.mooreds.com/wordpress/archives/000529

  However, others do not even recommend to compute password hashs on the
  client and propose to do that on the 
  server:http://www.owasp.org/index.php/Hashing_Javahttp://stackoverflow.com/q..

  From user's perspective, I would not be comfortable with transmitting
  my data unencrypted to the server (even using HTTPS), as the server-
  side may for example log my information (and my password!). Especially
  for the password-part I would feel unconfortable, as many people tend
  to reuse their passwords (please no discussion about this :-)).

  Currently, I see two options:
  a) Encrypt and decrypt the information on the client using JS/GWT.
  Pro: The password never leaves the browser, the unencrypted
  information never leaves the browser. Con: Depending on the size of
  the data the encryption/decryption may be slow; if loaded via HTTP,
  the JS code may be compromised, etc.
  b) Encrypt and decrypt the information on the server. Pro: Fast. Con:
  The information is transmitted unencrypted.

  What would be your recommendation?

  In case of server-side encryption, would it make sense to hash the
  password on client side and to use the hash to encrypt/decrypt? Or
  would that be a no-go?

  What happens if the user forgets his/her password? All data lost, I
  guess?

  I have no deep practical experience with cryptography, so I would
  appreciate any suggestions or pointers to resources in the web. My
  goal is not to have a bullet proof solution for highly sensitive
  information, but it should be an improvement compared to the current
  implementation (no HTTPs, no encryption).

Re: XML Validation directly

2010-07-29 Thread Danny Goovaerts

I use saxon from Michael Kay  (www.saxonica.com) for programmatic XML
validation. It's very good, but it does not proivided much more
detailed error messages.

You mention that you need this during development time. Do you want to
validate XML files that you
construct by hand before using them in your application? In that case,
I would suggest to invest in a XML editor that provides
validation. These generally provide much more detailed error messages,
including the line numbers where the error occurs.
 I use XML Studio from Progress, but there are others out there
(Altova XML Spy, probably also some open source or  Eclipse plug ins).
The investment in the license has been paid back multiple times in
saved effort.

Re: Do we have any Library for OpenID autentication(Authentication using Google accounts/Face book etc.)

2010-07-29 Thread Danny Goovaerts

I've implemented support for openID with special case for Google and
Yahoo mail (www.cellamea.eu).

I've written a servlet that uses openid4java to interact with the
openid providers. I can make the code available. On this moment,
it's not packaged in an isolated way, so it's not usable out of the
box, but it shows what you need to do.

I wanted also to provide support for Facebook, MSN, LinkedIn etc...
but I don't think that they are pure openid providers and I have not
yet found the time
to investigate the peculiarities of their authentication protocol.

Another possibility is to look at Janrain Engage , formerly known as
RPX (www.janrain.com). They support a whole variety of authentication
providers (that's their business).
I looked at it at the time, but I could not figure out how to
integrate it with a GWT frontend (interacting from GWT with the
Janrain's popup), and with my backend. It would be great if Janrain
could provide a GWT
integration. Anyone from Janrain on this mailing list?

Re: Mixed content warning on Chrome (skull and bones)

2010-07-15 Thread Danny Goovaerts

Thanks,
I'll go for the cache-control public solution that you suggest such
that the users can be confident about the confidentiality.
I've tested with FF3 and IE7. These browsers seem to persistently
cache the js when cache-control public is set on the reply headers.
I don't know about Chrome. Speedtracer shows From cache :false but I
do find the components in the cache.
I don't know how the mobile browser handle it, but the js files are
probably too big anyway to be cached.

 While I agree that the icon may be a little scary to uninformed users,
 I think it is probably better that way for the reasons I specified

 which parts of the page are not secure so that advanced users can know
 if there is something fishy going on.  Just last night I had 2 of my
 friends who are very non-technical ask me about security when it comes
 to using free wifi.  They have no clue what SSL is and it is much
 easier for me to tell them to not put in any sensitive information
 unless there is a lock icon on their screen.  In your purposes you are
 only loading javascript that has not data through an unencrypted
 connection, but what is to keep you from doing jsonp and sending
 unencrypted data, which from the browsers perspective looks exactly
 the same, loading a javascript file.  But from the users perspective
 one is sending personal information over an unencrypted connection and
 they should be notified because it is fairly serious.

Re: the button and its infoLabel problem...

2010-07-13 Thread Danny Goovaerts

I think that you need a deferred command to handle this. Limit your
clickhandler to set the infoLabel to Beginning and then launch a
deferred command who's execute method performs the search and then
updates the label.
In this way, the execution thread will finnish, causing the screen to
be updated with the beginning label and then only the defrred command
will be executed.

 thank Andreas and Aditya for your explanation.

 however the problem has nothing to do with RPC, the search operation
 i mentioned above is simply a local operation such as sort a large
 chunk of data which will take seconds to completed. meanwhile the
 client is unresponsive until the click OnClick() is completed, you can
 simply simulate this situation by doing a  while loop.

 is there other way i can see the beginning... ? or GWT has the
 ability to make UI responsive when it doing a time-consuming operation
 in client?

 thanks.

  HeyShelley,

  a bit of further information is missing but may it be that you issue
  an RPC between infoLabel.setText(Beginning); and
  infoLabel.setText(Completed);?

  If so you simply forgot the async nature of GWT RPC. Your code in
  onClick(...) will not sort of stop or wait until the RPC finishes and
  continue afterwards. That's why infoLabel.setText(Completed);
  will be immediately executed after infoLabel.setText(Beginning);
  and you're simply way to slow to see it.

  What you could do instead is call infoLabel.setText(Completed);
  in your onSuccess(...) in case I'm right with RPC or in the callback
  of whatever request you do for your search operation.

Re: GWT and CSS

2010-06-16 Thread Danny Goovaerts

Magnus,

standard.css is added after your style sheets are loaded. Unless
your style definitions are more selective that the definitions in
standard.css, the definitions in standard.css take precedence.
There are to possible solutions

- make your selectors more precise(googleon css priority for detailed
descriptions, much better that I could do here)
- mark your style definition as !important, for example, that's how I
override the settings for .gwt-button

.authenticate-button {
  background: white none  !important ;
  margin:2px !important;
}

  Hi Magnus,

   So what is the way one should use CSS? Is it possible to inherit a
   style into another style, e. g. my-button inherits gwt-Button, so
   that I just add my adjustments?

  just try to use addStyleName() instead of setStylePrimaryName(). By
  this you preserve the default standard.css styling of your elements
  and you can add additional formatting. More specific, the button would
  still have the class gwt-Button followed by your specific class which
  you can add to any CSS file linked in the main page.

  However, as GWT adds its standard.css as last css file you may still
  experience strage overruling of your styles (using Firebug helps to
  understand what is overruled by what).

  If that standard.css overruling is an issue for you, my blog post
  GWT's standard.css killed my page layout may help you:

Re: ClickHandler not called on second click

2010-06-03 Thread Danny Goovaerts

I think that I have found the underlying cause. In the ClickHandler, I
disable and enable the button. This incorrectly sets the state of the
button which then leads to the ClickHandler not being called.

I have a workaround in my application by not reenabling the button in
the ClickHandler if it already is enabled.

For reference :

http://code.google.com/p/google-web-toolkit/issues/detail?id=2885q=button%20click%20twice

ClickHandler not called on second click

2010-06-01 Thread Danny Goovaerts

I have a button with a ClickHandler. When I move the mouse over the
button and click the button, the ClickHandler is called. When I do no
move the mouse away from the button, the ClickHandler is not called on
any subsequent clicks. I have to move the mouse away from the button
and back. Then the ClickHandler is called when I click again.

To investigate, I have added a MouseDownHandler and a MouseUpHandler.
These are called on subsequent clicks, only the ClickHandler is not
called.
As the focus stays on the button, I have tried hitting the enter key.
This triggers calling the ClickHandler.

I 've tried adding a DeferredCommand to the ClickHandler with a
variaty of actions(remove focus, remove focus and set focus again),
but this does not change anything.

Environment
- GWT 2.0.3
- Vista
- Chrome 6.0.408.1 dev / Firefox 3.5.9/ Internet Explorer 7.0

There are several posts in this forum that describe a similar
behaviour (e.g.

but none have a solution.

Re: ClickHandler not called on second click

2010-06-01 Thread Danny Goovaerts

My application is quite large. The button is several levels deep,
i.e. in a FlowPanel which itself is in a HorizontalPaneI in a hierachy
of divs. I will try to isolate while still reproducing the error.
I would also try to step through the code in a debugger, but
unfortunaly for this I need to move the mouse from the page to
Eclipse, which prevents from reproducing the error.

Re: Facing problem tackling browser refresh

2010-04-20 Thread Danny Goovaerts

I faced exactly the same problem (see
http://groups.google.com/group/google-web-toolkit/browse_thread/thread/36979a4e8e51fdc5#
)
I concluded that in case of a refresh, the async call is cancelled in
the browser before it has concluded.
I solved the problem by waiting until the onSuccess() of the
callback was called. This waitingf is implemented by using a timer
that fires repeatdly until it is stopped in the
onSuccess() method of the RPC callback.

Here is the main piece of code

//code called in the ClosingHandler
final AsyncCompletionFlag flag= new AsyncCompletionFlag() ;
SessionGWTInterface.Util.getInstance().transfersSave(xml.toString(),
new AsyncCallbackString() {

public void onFailure(Throwable caught) {
   flag.setDone() ;
   return ;
}

public void onSuccess(String result) {
   flag.setDone() ;
   return ;
}
  }) ;
  //We need to have this to be sure to continue running until the RPC
completes. If not, it can be cancelled before
  //it acttually runs
 AsyncCompletionChecker checker = new AsyncCompletionChecker(flag) ;
 checker.run() ;

package eu.oobikwe.gwt.rpc;

import com.google.gwt.user.client.Timer;

public class AsyncCompletionChecker extends Timer{

private static int WAIT_TIME = 10 ;

private int waitTime ;
private AsyncCompletionFlag flag ;

public AsyncCompletionChecker(AsyncCompletionFlag flag) {
this(flag,WAIT_TIME) ;
}

public AsyncCompletionChecker(AsyncCompletionFlag flag,int waitTime)
{
super();
if(waitTime  0) {
this.waitTime = waitTime;
}
else {
this.waitTime = WAIT_TIME ;
}
this.flag = flag ;
}

@Override
public void run() {
if(!flag.isDone()) {
this.schedule(waitTime) ;
}
}


}

package eu.oobikwe.gwt.rpc;

public class AsyncCompletionFlag {
private boolean done ;

public AsyncCompletionFlag () {
super() ;
done = false ;
}
public boolean isDone () {
return done ;
}

public void setDone() {
done = true ;
}

}

This works for me.

Re: Async RPC during CloseHandler.onClose() cancelled?

  In the application that I'm building  I've implemented a
  CloseHandler.onClose() which saves the local state in the database at
  the server side. This state is reloaded automatically when you log on
  the next time (fromthe same browser or from another browser, that's
  why I am not storing it in a cookie in the client).

  This all works as expected when you close the browser (or the browser
  tab) or when you navigate to another url.
  The application is supported in multiple languages . I switch language
  by replacing the URL by a new URL with locale query parameter (for
  example, the URL for the default language ishttp://www.mysite.eu/,
  the URL for the french version ishttp://www.mysite.eu/?locale=fr).
  This causes a reload and the application is reinitialized in the new
  locale.

  However in this case, the async call in the CloseHandler.onClose()
  method apparently is not called or it is called, but it is cancelled.
  I'm convinved that it is called but it is cancelled as a result of a
  timing issue.
  I've done the following tests:
  * in web mode, the problem occurs
  * in web mode, when I have emptied the browser cache, the problem does
  not occur
  * in hosted mode when I step through it in the debugger, the
  CloseHandler.onClose() method is called and the RPC succeeds
  * in hosted mode, not in the debugger, the RPC succeeds
  * I've also tried moving the RPC call in a Window.closingHandler where
  I set a message in the ClosingEvent. This causes a popup window. In
  this case, the RPC call also succeeds

  This leads me to the conclusion that in in Web mode, the reload
  happens fast when the HTML page and the java script are cached, and
  that this causes the RPCto be canceled.

  What do you think?

  Is there a way to prevent the RPC call from being cancelled?

 Using onClose to save things is unreliable and risky (you'd better
 have an explicit save button and in case you have unsaved changes
 ask the user to save them before closing, using a ClosingHandler).

 In the case where you reload the app (with a slightly different URL),
 why not doing the RPC and do the reload in the onSuccess? (and because
 you have no unsaved changes, you don't need to save again in the
 onClose, or warn/ask the user in the ClosingHandler)

Re: Unable to migrate GWT application to version 2.03 due to problem with internationalization

2010-03-19 Thread Danny Goovaerts

es_GTC is normally not a valid locale. The country part of a locale
is the two character ISO country code. GTC is not a valid country
code.
A reason might be that GWT 1.5 was not strict about the country code
format, and that 2.0 is much stricter.

 I am trying to migrate a GWT 1.5 application (which definitely works

         extend-property name=locale values=es/
         extend-property name=locale values=es_GTC/
         extend-property name=locale values=en/

 The problem comes when the compiler attempts to compile the locale
 es_GTC and the file InternationalizationConstants_es_GTC.properties

 The error from the compiler was as follows :

 This previously worked with GWT 1.5. If I remove the locale

 extend-property name=locale values=es_GTC/

 from the Main.gwt.xml file, the application compiles and runs without
 problem. It seems that the GWT compiler has a problem with the -
 character in the name of the autogenerated java method which is

 public class LocaleInfoImpl_es-gtc extends LocaleInfoImpl_shared {

 Anybody got any suggestions? I've looked in the documentation for GWT
 2.x and there is nothing to indicate that this has changed.

Re: How do I use my own server in hosted mode instead of GWT's built-in Jetty instance?

2009-12-10 Thread Danny Goovaerts

When you run OOPHM without the built in Jetty, your RPC calls will go
to your instance of Tomcat (or to be more precise,
to the server that is listening on the port that you specify in the
URL : http://localhost:port/cellamea.html?
gwt.codesvr=192.168.1.102:9997,
The URL proposed in the Development Mode window is
 http://localhost/cellamea.html?gwt.codesvr=192.168.1.102:9997
supposing that you run your server on the standard port 80).

Changes that you make to your code in the debugger will only affect
client side code (after you refresh your browser). Changes to
your server code are not picked up automatically by your instance of
Tomcat. Depending on your deployment,
you will need to rebuild/redeploy/restart your Tomcat (similar to
pushing the Reload web server button in the Development Mode window
in Eclipse).

If you want to actually debug in Tomcat, start Tomcat in debugging
mode and start a debugging session in Eclipse to a remote JVM. Changes
to
your code will similarly not be picked up by Tomcat , needing a
rebuild/redeploy/restarts sequence.
You can run your application in Web mode (without debugging the client
side) or you can also debug your application in development mode
without the
built in server. It all depends what you need to investigate.

Danny

P.S. 2.0 is great. Thanks to everyone who contributed!

 Then I start my own server (Tomcat with JAAS j_security enabled), but
 it doesn't seem to pick up changes with my OOPHM firefox.
 How do I get my server (Tomcat) to understand:

Tomcat RPC Failure on Lost Client Connections.

2009-11-16 Thread Danny

I get a  Exception while dispatching incoming RPC call exception in
Tomcat after, what I believe is caused by an RPC response not finding
the client that made the request.  The stack print out is included
below.  I say that I believe this is the problem, but I have not been
able to reproduce the error.

Can someone with more Tomcat experience than me, see if my belief is
well founded?  Regardless, does someone have a solution?  My system
seems to be running OK.  Is my worry mostly about Tomcat filling my
web host's disk space with exception messages?

Thanks,

IE8 and Compatibility View settings and ListBoxes

2009-11-14 Thread Danny

My version of IE8 was accidentally set to Display all Websites in
Compatibility View.  This seemed to not hurt anything in my
application at first, but later I found that ListBoxes would not
display properly, i.e., not at all.  I guess GWT generates ListBox
code for IE8 that is not compatible with older versions.

I will make sure to inform my users to not use compatibility mode for
IE8.  IE8 permits selecting compatibility mode for specific websites,
but this is a bit messy.

I admit that this is a Microsoft, rather than GWT, problem.  Maybe it
is too late for 1.7, but would it be possible for 2.0 to generate
ListBox code for all versions of IE?  But, who knows what other
inconsistencies we will find from mighty Microsoft?

Thanks,

Danny

inherit modul for hibernate

Hello,

I try to integrate hibernate into a GWT 1.6 project. I've done it with
the help of: 
http://code.google.com/intl/de-DE/webtoolkit/articles/using_gwt_with_hibernate.html
and used gilead.

But when I run my application it says in the log:
No source code is available for type org.hibernate.SessionFactory; did
you forget to inherit a required module?
No source code is available for type org.hibernate.cfg.Configuration;
did you forget to inherit a required module?
No source code is available for type
java.lang.Exception.InInitializeError; did you forget to inherit a
required module?

But I've imported the mentioned classes and in my app.gwt.xml I've
added: inherits name=net.sf.gilead.Adapter4Gwt15 /

Has anyone ideas what to check why it does not work?

Thanks in advance

Frame Height 100%

2009-08-24 Thread Danny


Does anyone have a browser independent way to set a frame's height to
100% inside a panel that already has its height set to 100%.   I want
to open a frame to a URL (e.g., google.com), such that the frame
expands to the full size of the page pointed to by the URL.  Setting a
frame's width to 100%. or setting a frame's height to a fixed value
both work.

A quick search finds that iframes have this problem: setting its
height to 100% does not work in all browsers.  Solutions suggest
making sure that all parent objects that contain the iframe have a
style of height:100% or setting the height with Javascript.  I have
tried to set the parents of my frame to height:100%, but have not
met with success.  I am not wild about using Javascript.

Thanks,

Danny

GWT - JFreeChart Dependency in Terms Conditions

2009-08-13 Thread Danny Robinson


Please can someone explain why JFreeChart is listed as a 3rd party
library for GWT in GWT's Terms  Conditions page.  Specifically, I
need to understand if this is present as a dependency for development
(like Jetty), or the JFreeChart stuff actually is present somehow in
the javascript/compiled output - if so, is it only necessary for
certain components.

Many thanks - just trying to track down all the runtime license
dependencies for our external software.

Regards,

D.

ps - great product by the way.

Re: How to use the new WAR file to deploy a simple web application.

Thanks, doopa.
The steps in the GWT documentation are basically what I have done in

is build a .war file and TomCat would explode everything into the
right places.  I guess I will continue as before.

 Then navigate to localhost:8080/com.example.Module/index.html

 And then you can have the app pages served by tomcat. The war file is
 simply deployed to tomcat/webapps/com.example.Module.war

 Hope that makes sense.

 When you have your project configured this way, you can select the
 project, and then select File/Export/Web/War file.

 Save it to {path}/ROOT.war

 and that's about it.

 Saving it or renaming it to 'ROOT.war' should do what you want; your
 project will deploy athttp://server/

GWT 1.6, Google App Engine, and java.awt.image.*

I am trying to put my application under GWT 1.6, but I am having

Re: Acces to GWT JavaDoc in Eclipse

2009-04-01 Thread Danny Schimke

Hi Stefan!

You are right: I've removed gwt-servlet from the POM dependencies of the
corresponding project, because I don't need it yet. If I need this I will
create a separate server/backend- project which does. And now I have
access to the JavaDoc.

Thank you very much!
-Danny

2009/4/1 Stefan Hübner sthueb...@googlemail.com


 Danny,

 maybe this is caused due to both gwt-servlet and gwt-user are on
 classpath? For the former, the Maven Central repo doesn't provide a
 source ball but the latter it does. I've experienced this behaviour
 earlier and the only workaround so far was to attach the sources of
 gwt-user to gwt-servlet as well. This seems a weird thing to do,
 though. To get the sources use -DdownloadSources -DdownloadJavadocs
 while invoking mvn eclipse:eclipse.

 Why is gwt-servlet on your classpath in the first place? Maybe because
 it's necessary for RemoteServiceServlet?

 Anyways, I would be happy if gwt-servlet sources would be provided too.

Re: FlexTable : how to get not wrapping text functionality

2009-03-30 Thread Danny Schimke

Hi Suren!

I dont know why this is not working, but you can use a Label, set the word
wrap of the label to false and add this label to one of your FlexTable's
cell. This should work.

-Danny

2009/3/30 Suren nsurendi...@gmail.com


 Hi All,

 I am using FlexTable in a grid format to display text. I have a
 situation like, the width of the particular column needs to be fixed.
 And in that case, I need to show whatever text is fit into that width.
 I dont want to use wordwrap, which inturn affects my layout. Or I dont
 want to display the full lengthy text too.

 I 've tried
 [code]
 FlexTable f1 = new FlexTable();

f1.setText(0, 0, This is a very long text);
f1.setBorderWidth(2);
f1.getCellFormatter().setWidth(0,0,2px);
f1.getCellFormatter().setWordWrap(0, 0, false);
 [/code

 In the above case, I set the wordwrap to false, but still I am getting
 the wrapped text in the Flextable

 Could anyone please suggest any ways to acheive this?

 Thanks
 Suren

Re: FlexTable : how to get not wrapping text functionality

2009-03-30 Thread Danny Schimke

In standard a table wraps your text. You could try to add a the following
CSS class to the cell (td- element of the table), that should not wrap its
text.

.no-wrap {
  white-space: nowrap;
}

In the following example- HTML the text is not breaking although the table
has a width of 100px. The Table's width will grow up.

table class=non-wrapping-tablewidth=100px border=1
  tr
td class=no-wrap
  to long text, to long text, to long text, to long text
/td
  /tr
/table

If you want to say, that the complete table should not wraps its text you
can do it with CSS, instead of adding the no-wrap CSS class to each td
element.

.non-wrapping-table tr td {
  white-space: nowrap;
}

hope that will help...

-Danny

2009/3/30 Suren nsurendi...@gmail.com


 Hi Danny,

 Thanks for the reply.

 I should have mentioned earlier that, I 've tried that option too.
 that is, I set the text to a label and disable the wordwrap to that
 label and add that label to a FlexTable using setWidget method.

 Result the same..

 Still I am getting either full long text with the increased width, or
 wrapped text with the proper width.

 All I want is some knid of truncated text( to appear like truncated
 text, but actually not, since that cell dont have enough space to
 display that)

 I have a doubt here. Did Flextable has the default settings to adjust
 the column width according to the text's length? And wrap the text if
 the width is set?

 If so, what if I dont want that functionality? I mean how can I
 disable that? apart from the wordwrap method

 Thanks
 Suren

  I dont know why this is not working, but you can use a Label, set the

   Hi All,
 
   I am using FlexTable in a grid format to display text. I have a
   situation like, the width of the particular column needs to be fixed.
   And in that case, I need to show whatever text is fit into that width.
   I dont want to use wordwrap, which inturn affects my layout. Or I dont
   want to display the full lengthy text too.
 
   I 've tried
   [code]
   FlexTable f1 = new FlexTable();
 
  f1.setText(0, 0, This is a very long text);
  f1.setBorderWidth(2);
  f1.getCellFormatter().setWidth(0,0,2px);
  f1.getCellFormatter().setWordWrap(0, 0, false);
   [/code
 
   In the above case, I set the wordwrap to false, but still I am getting
   the wrapped text in the Flextable
 
   Could anyone please suggest any ways to acheive this?
 
   Thanks

Event listening on ListBox in a CaptipnPanel's Legend

2009-03-26 Thread Danny Schimke

Hello!

A CaptionPanel can contains HTML in its legend. I hve to add a ListBox-
Element there. But I have to listen on it (change- events). How do I have to
add the ListBox as a part of the legend- Element to the Caption so that I
still can listen on its events?

Thank you very much!

Re: Set CSS for ListBox Items working in Firefox not in Safari

2009-03-24 Thread Danny Schimke

My problem is similar. My CSS for option- tag's of a select- element are
not shown dynamically their new CSS- layout in IE. I'am setting the CSS-
classes like the following:

listBox.getElement().getElementsByTagName(option).getItem(index).setClassName(empty-option);

My CSS looks like:

.empty-option {
  color: #F2A336;
}

This is only a color- change...
But this color is not shown in IE after adding the class. If I hide and show
the listBox again the colors are updated correctly in IE. But this cannot be
a correct workaround for me...

Example:

listBox.getElement().getElementsByTagName(option).getItem(index).setClassName(empty-option);
// after this the color of  css class empty-option is shown correctly in FF,
not IE
listBox.setVisible(false);
listBox.setVisible(true);
// now the color is shown correctly in IE too

This means, that the CSS works in all browsers. It's not a CSS- issue... I
dont know how to fix this.

-Danny

2009/3/24 Shashi Kant kant.shash...@gmail.com


 Oh you are using an image. I dont think IE supports that. ,This reason
 behind this is because of how IE gets the base for the HTML Select
 tag - it's derived from the Win32api - the same reason why dropdown
 lists and select lists have a nasty habit of rendering above
 everything else on the html page.

 BUT, you could still experiment with background-color. That should
 work like in this example:

html xmlns=http://www.w3.org/1999/xhtml;
head
titleUntitled Page/title
style type=text/css media=screen

.optionBold {background-color: Fuchsia; font-weight:
 bold;}

/style
/head
body
form id=form1
div
select id=htmlSelect multiple=multiple size=5
 
optionNon-styled 1/option
optionNon-styled 2/option
option class=optionBoldStyled/option
option style=background-color: Aqua; font-weight:
 bold;Styled
 inline/option
/select

/div
/form
/body
/html

Re: ReplacementString support for MultiWordSuggestOracle for 1.6

2009-03-22 Thread Danny Goovaerts


Sorry, I hit send too fast.

I want to use replacementString with a MultiWordOracleSuggestion. This
is not possible today, also not in RC 1.6.
I currently workaround the issue by implementing a SuggestOracle
embeds a MultiWordSuggestOracle. The implementation of
requestSuggestions delegates to the embedded MultiWordSuggestOracle in
the following way

...

private MultiWordSuggestOracle oracle ;
private HashMapString,Suggestion suggestions ;
private MyCallBack myCallBack ;
...

public void requestSuggestions(Request request, Callback callback) {
//delegate to myCallBack and intercept the responses
myCallBack.setOcb(callback) ;
oracle.requestSuggestions(request, myCallBack) ;
}
...

private class MyCallBack implements Callback {
private Callback  ocb ;

public void setOcb(Callback ocb) {
this.ocb = ocb;
}

public void onSuggestionsReady(Request request, Response 
response) {
// Create a new response
Response myResponse = new Response() ;
LinkedListSuggestion responses = new 
LinkedListSuggestion() ;
   //MultiWordSuggestOracle returns the original
suggestion as replacementString
   // we use this as key to look upthe actual
suggestion that we want to provide
for(Suggestion suggestion : response.getSuggestions()) {

responses.add(suggestions.get(suggestion.getReplacementString
())) ;
}
myResponse.setSuggestions(responses) ;
ocb.onSuggestionsReady(request, myResponse) ;
}

}


This works, but it would be much easier if we could simply provide the
replacementStrings to the MultiWordSuggestOracle.
Issue 2695 actually submits this as an enhancement request. Its status
is accepted. Any chance that this can make it into 1.6?

Thanks (not just for answers to this post but for the tremendous tool
that GWT is)

How to sort a list with objects on client side?

2009-03-19 Thread Danny Schimke

Hello!

I have a list with objects I've got from backend-side. Every object has a
getSort() method, which returns an integer value. I've never worked with
Comparator before, but I tried like the following:

public ListObjecttype getObjectListe() {
ListObjecttype sortedList = model.getObjects();
Collections.sort(sortedList, new ComparatorObjecttype() {
public int compare(Objecttype o1, Objecttype o2) {
// compare the o1.getSort() value with o2.getSort() value here
}
});
return sortedList;
}

And this is the error I got:

[ERROR] Uncaught exception escaped
java.lang.UnsupportedOperationException: null
at
com.incowia.tkbase.unternehmenspflege.core.client.BaseReferenceList.toArray(BaseReferenceList.java:166)

What have I to do, to sort my list?

DialogBox's height not based on its content

2009-03-17 Thread Danny Schimke

I have a dialog box with a invisible widget at the dialogs bottom. There is
a button to show this (invisible) widget. The Widget is shown and the dialog
box's size grows up (correctly). But when I hide this widget the height of
the dialog box is not reduced back to the initial state. It stays large and
that seems not pretty. How can I fix this?

Hallo Eva!

Es gibt noch viele andere Styles (Detailled, ua.), aber schau dafür am

Re: Restrain the DialogBox to move out of browser window

2009-03-09 Thread Danny Schimke

After weekend I tried again and it worked very well... I don't know the
reason for the not working code last week, but here is my code, that worked
very well:

@Override
public void onMouseMove(Widget sender, int x, int y) {
  super.onMouseMove(sender, x, y);
  if (this.getPopupLeft() + this.getOffsetWidth()  Window.getClientWidth())
{
this.setPopupPosition(Window.getClientWidth() - this.getOffsetWidth(),
this.getPopupTop());
  }
  if (this.getPopupTop() + this.getOffsetHeight() 
Window.getClientHeight()) {
this.setPopupPosition(this.getPopupLeft(), Window.getClientHeight() -
this.getOffsetHeight());
  }
}

The dialog window does not move out of the visible window area!
Thank you very much Sumit! The idea of overriding the onMouse- Events is THE
idea!

2009/3/5 Sumit Chandel sumitchan...@google.com

 Hi Danny,
 That shouldn't be the case. Which browser were you testing on when this
 occurred?

 I ran the code snippet below and tested it out in hosted IE6, web mode
 IE6/7/8, FF3 and Chrome, and in all cases the onMouseUp() method was called
 and the dialog box was repositioned. Give it a try and let me know how it
 looks for you.

 public void onModuleLoad() {
   final DialogBox dialogBox = new DialogBox() {
 public void onMouseUp(Widget sender, int x, int y) {
   this.setPopupPosition(0, 0);
   super.onMouseUp(sender, x, y);
 }
   };
   dialogBox.setHTML(bBonjour la police!/b);
   RootPanel.get().add(dialogBox);
   dialogBox.center();
 }

 Hope that helps,

 where it was when the user lets go of it.

  For example:

Window.confirm in timer.run()

Hello!

I am using a timer to ask the user after xy minutes to save his changes to
database. In the run() method of timer I ask the user wheather he want to
save the changes. If the user clicks OK I'll save othwerwise I'll do
nothing. I shedule the timer repeatly after xy minutes. When does the timer
reruns? After handling the run() method? I recognized that the timer reruns
while the confirm message is shown. Is this an issue or correct? Should the
timer rerun while its run() method is not finished? I occurs in Firefox, in
IE it works like I am thinking how it should work.

Example for Error:

- Rerunning timer every 1 minute
- Confirmation is shown after 1 minute, user does *not* click  *OK* or *
Cancel*
- After two or more minutes I'll click OK or Cancel and the confirm window
closes. But the confirm window of the second timer run is shown.
- The window is maximal shown two times (e.g. when I am waiting three or
more minutes)

It should be not very difficult to use a workaround, but I want to
understand the correct working of the GWT timer.

Thank you!

 threaded (some multi-threading Javascript support coming in FF3.1 that I
 know of).  Anyways your problem is this:

 run()
 showWindow()
 browser keeps generating timer event probably because that comes from the
 OS  there's no locking in place
 user clicks on button
 next event is shown

 Instead do this:

 timer.schedule(1000);
 run() {
showWindow()
timer.schedule(1000);

 }

 Hello!

 I am using a timer to ask the user after xy minutes to save his changes to

 save the changes. If the user clicks OK I'll save othwerwise I'll do
 nothing. I shedule the timer repeatly after xy minutes. When does the timer
 reruns? After handling the run() method? I recognized that the timer reruns
 while the confirm message is shown. Is this an issue or correct? Should the
 timer rerun while its run() method is not finished? I occurs in Firefox, in
 IE it works like I am thinking how it should work.

 Example for Error:

 - Rerunning timer every 1 minute
 - Confirmation is shown after 1 minute, user does *not* click  *OK* or *
 Cancel*
 - After two or more minutes I'll click OK or Cancel and the confirm window
 closes. But the confirm window of the second timer run is shown.
 - The window is maximal shown two times (e.g. when I am waiting three or
 more minutes)

 It should be not very difficult to use a workaround, but I want to
 understand the correct working of the GWT timer.

 Thank you!

Re: Window.confirm in timer.run()

Yeah! I canceled the timer and restarted it in in the run() method... It is
about the way you've advised me.

Thank you for your post! I've searched a long time for something like

Should there a heartbeat which checks the session validity?

Question about mGoogle Maps URL and its parameter gwt

2009-02-27 Thread Danny Schimke

Hello!

Does anyone know what is the parameter gwt with the value1 for? The URL
looks like the following:

http://maps.google.com/maps?*gwt=1*amp;file=apiamp;v=2amp;key=

I can't make differences between the functionality of URL with parameters
and without parameters. Is the this parameter needed and why? Are there
other possible values instead of 1 and what does they mean?

Thank you!

Re: Apply CSS in editor area of RichTextArea

2009-02-25 Thread Danny Schimke

I've seen many examples where JSNI is used, like the following:

private native void myJsniMethod(Element oElement)/*-{
  var oDoc = oElement.contentWindow;
  // var oDoc = oElement.contentWindow || oElement.contentDocument;
  if (oDoc.document != null) {
oDoc = oDoc.document;
// more actions here...
  }
}-*/;

I tried to use JSNI method too. But an error occurs when trying to call *
oElement.contentWindow* because its value is *null* (I've seen in Firefox,
In IE you cant see the reason for throwing the error). Why does it should
work in many examples you can find in the web? Is there anything special to
watch?

2009/2/24 Danny Schimke schimk...@googlemail.com

 Hi Omer!

 1. Yes I am using Windows and yes: Hosted Mode uses the installed IE.
 2. The error occurs in compiled mode (Firefox, IE) too.

 I show a preview for multilingual text (english, german, french, etc.).
 It's font-family is shown in Arial,Helvetica, but the RichTextArea is
 using the browsers font (If I am not mistaken!?). It does not look nice,
 when the editors text has a different font, than its preview...

 I hope I'll crack this in future ;)

 Thank you Omer!!!
 -Danny

 2009/2/24 A Friend Of Yours omer.akh...@gmail.com


  Any Idea, why the error occurs?

 No; not really!

 If you could provide more details:
 1. Are you having this error in Hosted Mode or Web Mode?
 Because some javascript trick don't work in Hosted Mode so things like
 this happen.



 2. Hosted Mode: Are you using Windows?
 Hosted Mode browser in windows uses Internet Explorer components to
 render its view (not sure if it is true though). While I used this in
 linux where Hosted Mode uses mozilla components.

 3. Web Mode: Goes without saying; are you using Internet Explorer for
 Web Mode?
 As I had mentioned, I have only tested this solution on Firefox in
 Linux.

 Hope this helps

I have a textbox which should change some data by onChange. If I am closing
the browser window over it's close button (x) the onChange and onLostFocus
is not fired. Is it possible to solve this problem? I can not use a

event instead of multiple).

Re: Restrain the DialogBox to move out of browser window

2009-02-23 Thread Danny Schimke

No idea?

2009/1/28 Danny Schimke schimk...@googlemail.com

 Hello!

 Is it possible to restrain the DialogBox to move out on right and bottom
 side of the browsers windows? When I move the box over it's header it should
 stay completely in the visible browser window area, because I disabled the
 scroll bars and the user should not be able to move the DialogBox in a not
 viewed area.

 And second: in IE6 the DialogBox is only dragable by the text in it's
 header. Is there a clean way to allow IE6 users to dragdrop the box like in
 FF or IE7 over the complete header?

 Thank you very much!

Re: Changing color of text on fly.

2009-02-23 Thread Danny Schimke

Hi!

If I understood correctly you want to change the color of option- Tags of
a select- input (ListBox)!?

you can add a CSS- class:

listBox.getElement().getElementsByTagName(option).getItem(index).setClassName(your
CSS- classname)

But in IE I habe a problem too... the color only changes, if the ListBox was
drawing again on the screen after adding the class.

 Hi,

 I am using the gwt google map api.  Previously, I had a hypertext link
 on a InfoWindow in Google Maps.  This link loaded a new page.  I am
 now trying to implement the same functionality in GWT.  I can still
 add a hypertext link in the InfoWindowContent but I can not figure out
 how to have it throw an event in my application.

 Is it possible to add a hypertext link (or button) on a InfoWindow
 that triggers an event in GWT?

the reason why I am searching another HTML editor than GWT's
RichTextArea. I tried gwt-html-editor and it worked, but it was not what I
am searched for. The possibilities of using the Toolbar and the way to edit

Re: Script error in IE 7 in web mode

2009-02-06 Thread Danny Goovaerts


Arend,
Thanks for the reply. I've been able to pinpoint the place where the
problem occurs and it is indeed in a class where
I parse the XML reply coming back from the server. It was working fine
previously in all browsers. The difference is that the XML is larger
now. Maybe Internet Explorer has a limit on the size  XML documents
that it can handle. I will investigate further and post my findings.

event is called, but the onClick- event of the button is called too at same
the time. Saving is faster than onChange. I tried to handle the onClick
after other events have done their work by using a DeferedCommand. But is
doesn't work. Saving is allways faster than the onChange.

Is there a way to control the handling-order of events?

Thank you!

Script error in IE 7 in web mode

2009-02-05 Thread Danny Goovaerts


I have a GWT application that runs OK in hosted mode. When I compile
it, it gives a script error on Internet Explorer 7. The compile
version runs correctly in Firfox, Chrome and Safari.
I've turned on script debugging in IE7 and it gives me the following
message (translated from Dutch)
--
Line : 2
Character : 23530
Error : Exception activated but not handled
Code: 0
-

Can anyone point me to some documentation how I can further
investigate what's wrong. The application is quite big, so it's not so
easy to isolate the piece of code where it goes wrong.

Thanks,

Danny

Re: Call event after an other

2009-02-05 Thread Danny Schimke

It does not work...I am doing anything wrong.

Can you *explain how to use this*? I try to describe again: I habe 2 events,
both in a own class. The onClick from save button in class A and the
onChange from the textbox in class B. If the onChange is fired the save is
fired too (look at my first comment this thread). But I need the possibility
to wait starting onClick until onChange is running.

 Hi !

 You can control event propagation with low-level functions (onBrowserEvent,
 Event) ; in your case, use the Event.cancelBubble function :


 http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/Event.html#cancelBubble(boolean)http://google-web-toolkit.googlecode.com/svn/javadoc/1.5/com/google/gwt/user/client/Event.html#cancelBubble%28boolean%29

Re: Hosted Mode not refreshing

If you are using Eclipse do a clean on your Project(s) und refresh them.
Maybe it will help.

 Yup, I cleared the IE cache and still no joy.

 Any other suggestions, please?

Re: Button as hyperlink Look

Hi there!

Use CSS, like this:

.button-link {
  cursor: pointer;
  cursor: hand;
  border: none;
  /* Disable the button-style */
  background-color: transparent;
  padding: 0px;
  color: #4784C3;
  text-decoration: underline;
}

this lets your button look like a hyperlink!

 How can I achieve a Button widget as hyperlink Look n feel.
 I don't want to use an anchor Link as it opens a browser
 functionality.
 Rather I need just the button functionality.

Re: GWT-maps-api: Maps API has not been loaded

First *thanks* to *Eric Ayers* for your endeavours to assist me!

We found the reason which causes, that control are not visible in IE6 and
there where map loading problems. In IE6 internet options using HTTP 1.1
over Proxyconnections is deactivatd. E.g. IE7 this option is set by default
(This is an indication that the error only occurs in IE6). Since we have set
the setting to use HTTP 1.1 over proxyconnections everything works fine. Now
we can load and interact the map without problems in Internet Explorer 6.

-Danny

2009/1/26 Eric Ayers zun...@google.com


 1) Maybe there is  a cache somewhere that needs to be flushed (start
 with the browser cache)?

 2) You might try using a different version of the Maps API:

  http://code.google.com/apis/maps/documentation/#API_Updates

 3) Are you browsing the internet through a proxy?  could that be
 getting in your way?

 4) If that doesn't solve the issue, you could try configuring some
 kind of sniffer/proxy to print out the requests your browser is
 making.
