Re: Alignment of widgets

[Joe Cole]

If you are using flextables for forms you will want to set the width
of the first column widgets:

flextable.getCellFormatter().setWidth(0, "200px");

Re: SuggestBox hides RootLayoutPanel and all its contents

[hriess]

Is there in the meantime a solution for this problem? I am using a
DockLayoutPanel for the layout of the application. A SuggestBox (and
other PopupPanels) blanks the complete screen in IE7. After upgrade to
GWT 2.0, UiBinder and LayoutPanels I haven't tested my application
with IE7 for a long time. Have I to go back in time and check out a
rather old SVN version of my application?

Thank you
Holger

Re: UiHandlers in Extended Abstract Class

[matttai]

Hi Damien,

I thought u were just asking about binding UI elements across extended
and abstract classes which I have been able to successfully do
(example code above).
The UIHandlers however are a different story and don't work.

Hello matttai,

Is just the same question that you answered me few post before about
UiBinder and Abstract class. The error i posted is from the same
thing.
Extended class does'nt see UiHandlers from base class. Anyone knows is
it posible to make it work?

UiHandlers in Extended Abstract Class

[matttai]

Having trouble having UiHandlers register when extending from an
abstract class.

I can register UiHandlers in the abstract class fine, however the
extending class cannot register it's handles. Sample code below:

Abstract Class:

public abstract class GenericWidget extends Composite
{
@UiTemplate("template/GenericTemplate.ui.xml")
public interface GenericWidgetUiBinder extends UiBinder {}
private static GenericWidgetUiBinder uiBinder = GWT.create
(GenericWidgetUiBinder.class);

@UiField FlowPanel chromePane;
@UiField Panel contentPane;
@UiField Label title;
@UiField Button toggleButton;

public GenericWidget(boolean hasChrome, String chromeTitle)
{
initWidget(uiBinder.createAndBindUi(this));
contentPane.add(initContent());
}

@UiHandler("toggleButton")
public void handleClick(ClickEvent event)
{
//do stuff
}

protected abstract Widget initContent();
}

Extending class:

public class AddPersonWidget extends GenericWidget {

@UiTemplate("template/AddPersonTemplate.ui.xml")
public interface AddPersonUiBinder extends UiBinder {}
private static AddPersonUiBinder uiBinder = GWT.create
(AddPersonUiBinder.class);

@UiField private TextBox firstname;
@UiField private TextBox lastname;
@UiField private HTML errorMsg;
@UiField private Button submit;

public AddPersonWidget()
{
super(true, ADD_PERSON_WIDGET_TITLE);
}

@Override
protected Widget initContent()
{
Widget content = new Widget();
content = uiBinder.createAndBindUi(content);
return content;
}

@UiHandler("submit")
public void submitButtonIsClicked(ClickEvent event)
{
submit.setVisible(false);
}
}

The UiHandler in the extending class does not register? Thanks GWT
Users.

Re: Issues with Embedded History Changes

[Michael Mullen]

I just figured out my problem.  Although this does not strike me as a
good solution...

My onModuleLoad() function had to be changed to the following:

public onModuleLoad() {
   VerticalPanel vp = new VerticalPanel();
   vp.add(new MenuObject());
   RootPanel.get().add(vp);
   String initToken = History.getToken();
   if(initToken.length() > 0) {
  onHistoryChanged(initToken);
   } else {
  onHistoryChanged("Home");
   }
   History.addValueChangeHandler(this);
}

It appears that I cannot just add an object to the root panel outside
of another panel.

Re: Struts2 GWT and classpath

[finneycanhelp]

Hi,

I confirmed I am not getting a classpath issue.

Using firebug and firefox, I see the URL
http://localhost:/org.struts2kata.S2?gwt.codesvr=10.0.0.2:9997
does a redirect to http://localhost:/S2/  Not sure why

Then I see the following:
http://localhost:/S2/
http://localhost:/S2/S2.nocache.js
http://localhost:/S2/S2.nocache.js?compiled
http://localhost:/S2/gwt/standard/standard.css

The source of the page mentions  "Your web browser must have
JavaScript enabled" in the source.  My JavaScript works fine ( checked
using http://jsbin.com/ )


At this point, I am thinking of starting over with a non-maven struts2
application which is my ultimate goal anyway.  I am thinking of having
the two apps be totally separate somehow too.
http://www.vogella.de/articles/GWT/article.html#firstgwt_run perhaps.

Thanks.

UiBinder and non standard CSS properties.

[Carlos Aguayo]

Hi,
UiBinder can't seem to take non standard CSS properties.

I have the following:



  
  .test {
-moz-border-radius: 4px;
  }
  

  

  


And it shows the following warning when trying to display the page:
21:01:53.994 [WARN] [gwtsandbox] Line 3 column 20: encountered "-".
Was expecting one of: "}" ";" 

Is this as designed that you can't use non standard CSS properties?
Thanks,

onBlur called twice because of FocusWidget.setFocus implementation

[Stuart]

My use case:

I have a TextBox which I want to validate onBlur. If validation fails,
I want to setFocus on it again. Which makes onBlur fire again, hence
the validation routine runs again (not ideal, in fact, a defect in my
mind).

My code:
== snip ==
public void onBlur(BlurEvent event) {
  TextBox tb = (TextBox) event.getSource();
  try {
Long longValue = Long.valueOf(tb.getText());
  } catch (NumberFormatException e) {
// warn the user in the UI
// set the focus back on the TextBox
tb.setFocus(true);
  }
}
== end snip ==

The onBlur is running again because FocusWidget does this:

== snip ==
public void setFocus(boolean focused) {
if (focused) {
  impl.focus(getElement());
} else {
  impl.blur(getElement());
}
  }
== end snip ==

So, when I insert non-digits in my text box, and tab or click into the
next form element, onBlur fires once. In my catch block, I set the
focus again, which triggers onBlur again because of how
FocusWidget.setFocus is implemented.

This defect prevents me from displaying a message to the user just
once (ie, with an alert) or setting and clearing a message on fail/
pass of the validation.

Anyone have a workaround?

UiBinder + HTML + Widgets

[Eric]

Hello all,

I hope this is obvious and I'm just missing it, but I can't figure out
how to add a Widget to a DivElement or TableCellElement that I get
back from my uiBinder template.  Here is what I have:




[lots of eye candy that came from a graphic designer]

Logout
[more html]

   

[lots more stuff]




then in Java:
  @UiField
  LinkElement logoutLink;
  @UiField
  DivElement contentArea;

  public HasClickHandlers getLogoutLink() {
// This was easy
return Anchor.wrap(logoutLink);
  }

  public HasWidgets getContentArea() {
// I can't figure out what to put here.  Help! Please!
return null;
  }

How do I turn an Element into some kind of Panel?  Or add a Widget to
a container Element? Do I have to put ids on the elements and use
RootPanel.get("contentArea")?

Thanks in advance,
Eric

A Sexy/Slick GWT Application?

[Andy]

I've been looking at a lot of the demos for the 3rd party GWT plugins;
for example, SmartGWT, and read the various postings on this forum
about who's actually using GWT, but I was wondering if anyone knows of
a really sexy/slick GWT application that not only has a great design,
but uses animation in a meaningful way (rather than for the sake of
it), and even has custom widgets that are more than a collection of
assets arranged in a nice way.

I'm thinking of something along the lines of the Roambi iPhone app
(http://www.roambi.com) or theCappuccino-based Almost.as app (http//
almost.at) (in particular the timeline widget at the bottom of the
screen).

Re: Blur event on FocusPanel is triggered immediately following MouseDown event

[Sky]

Wow! Now another FocusPanel's MouseDown event doesn't even fire!
Except I can make it fire if I do the following. When I click on this
element (object B) another element (object A) is losing focus, so if I
put a breakpoint in the onBlur event on that item (object A), then
when I click on the other item (object B) Eclipse breaks into that
code, I hit F8 to continue and what do you know, the MouseDown event
actually fires and everything runs. Do you understand? The MouseDown
event on object B ONLY fires if I have a breakpoint in OnBlur event
for object A!

These problems are ONLY in chrome. All other browsers act as expected.

I can't possibly fix something like this. Can anyone help me? These
problems must be a GWT bug(s).

Re: Question regarding presenter in MVP pattern

[Eric]

This is in no way an authoritative answer, but I've decided for my app
that defining a Model class and setting and getting a list of that
model is the right way to go:

So I would add
 void setRecipeItems( List items) ;
 List getRecipeItem() ;

to your Display interface.  I'm not totally happy with it, but I think
it beats the parallel arrays solution hands down, especially when you
realize that you need a unit of measure.

Good luck,
Eric

Re: Issues with Embedded History Changes

[Michael Mullen]

I checked a few other things.

In my loading html document, I've got the following line in the body
section to add history support:


Is this the correct location to have this?

I also just noticed that HistoryListener was depreciated, so I updated
to ValueChangeHandler.  My main section is, for the most part:

public class entry implements EntryPoint, ValueChangeHandler {
   public onModuleLoad() {
  RootPanel.get().add(new MenuObject());
  String initToken = History.getToken();
  if(initToken.length() > 0) {
 onHistoryChanged(initToken);
  } else {
 onHistoryChanged("Home");
  }
  History.addValueChangeHandler(this);
   }
   public void onValueChange(ValueChangeEvent event) {
  onHistoryChanged((String) event.getValue());
   }
   public void onHistoryChanged(String token) {
  Window.alert("Testing " + token);
   }
}

When the page loads, a window appears alerting me to the name of the
token being loaded.  This also occurs while refreshing.  However with
the MenuBar that is displayed, the choice changes the token in the
URL, however no window appears.  If I select Reload in my browser, the
page loads and the window appears.

I've gone back and looked at the previous tutorials I was using for
reference, but it appears that I've got everything.  I could not find
anything in the Showcase example - it looks like I've got everything.

I'm using Chrome 4.0.302.3 dev, as well as Firefox 3.6 for testing.

By chance is there something that I'm missing?

Blur event on FocusPanel is triggered immediately following MouseDown event

[Sky]

I click on my FocusPanel and before MouseUp event fires, but after
MouseDown event, the Blur event is fired, which is very much
undesired.

This only happens in Chrome, so it may be a Chrome bug. It does not
happen in FF and IE.

It may be my fault, but I am not explicitly setting focus on any
elements in my MouseDown code. I do set other aspects of other
elements, like visibility.

Has anyone else experienced something like this before?

Re: UiBinder and abstract class

[matttai]

You are probably setting setWidget(uiBinder.createAndBindUi(this)); in
the extended class. I don't see your bind statement for the second
class so i cannot tell so it is just a guess.

Bind the loginbox content for the LoginDialogBox as a widget and pass
it in for your bind in the setContent(content); statement

Re: Is it possible to detect if a popup (opened by Window.open(..) ) has been closed?

[darkflame]

For other peoples reference I found a solution/work-around;

Triggered from the popup window itself, I added code that could
communicate back to that which opened it.

Native javascript like this would trigger the history;
window.opener.location.hash = "meep2";

Or something like this to trigger a native function on the source
window;
window.opener.sendFunctionToMainFrame('retestlogin','retestlogin');

Thanks for trying to help.

Re: Suggestions for dealing with Timers

[Sean]

Thanks Vitali, I just made a test with IncrementalCommand, and you are
correct. I wasn't seeing the behavior I was looking for.

And I misunderstood where you wanted to use the timers. I am smacking
my forehead for not figuring that out before. Thank you very much.
That is exactly what I need to do!

Re: Suggestions for dealing with Timers

[Vitali Lovich]

So you would obviously have to change it.  Incremental command wouldn't help
you since you are doing animation Incremental commands are just a way of
allowing long-running data processes to maintain an interactive UI -
otherwise the UI would block while you did your processing. Thus they don't
help you here since you cannot control the interval.

MyBinClass [] unsortedBins;
int interval = 1000;

new Timer() {
private final MyBinClass [] bins = unsortedBins;
private int bin = 0;
public void run()
{
if (bin >= bins.length) {
   return;
}
moveBinToCorrectSpot(bins[bin]);
bin++;
schedule(interval); // schedule the next step to run a
second after this one
}
}).schedule(0); // start the animation now.

This way, you can even adjust the sort interval between each step (if you
want to speed up during the animation or allow control by a slider).

Also, I'd take a look at the Animation
class as well which might help you with saying this animation must
complete in 10 seconds, and
base your calculations of the progress (since computer speed is variable)

Re: Suggestions for dealing with Timers

[Sean]

Hi Vitali,

That is what I'm doing now. However, I'm going to have something like
//For example
for(bin : bins)
{
   moveBinToCorrectSpot(bin)

}

So each Bin will get it's own timer in moveBinToCorrectSpot that moves
it to it's right spot. However, they'll all animate at the same time.

Jeff,

I will have to check out IncrementalCommand, I've never seen that
before.

Thanks for the tips all!

Usage of two modules that share sessions id ?

[Nico]

Hi,

I am building a website with GWT. There is a login page on this
website that send a session id to client when user is logged in. I'm
using the Servlet HttpSession object to get id.

Somewhere in the website, there is a link that load a new GWT module
page. This is a different module because this a big part of the
application that is very independant and could be packaged without the
website. Now, I would like that both module use same Session (do not
want to login user twice).

To do this, I store my session id in a cookie and when an application
loads, it reads cookie to know session Id (or send the client to the
login page if no cookie), then session it is checked on server.
This system works if I merge the two modules insite a single tomcat
application. They will use the same HttpSession.

But If I want to use the mechanism with Hosted mode, it does not work
since both application modules are running in a different Thread, and
each one have a different HttpSession.

Do you have an idea about how to have a such working system in Hosted
mode ?
Do you know too, if it is possible to debug two application at the
same time?
Eclipse allows to selects a port to start an application, (default is
) but we can't selects a port for the debug connection (default
9997). Is there a way to chose something difference than 9997 ?

Thanks,

Nicolas.

I created an app, and now I want to run it in a different HTML file. I
created the new HTML file, placed it in the war directory, made sure
the new HTML file has the correct RootPanels and changed the  in the web.xml file to refer to the new HTML file.

But my app is still not displaying in the new page. I even tried re-
compiling. Hosted mode loads the new page, but the app doesn't show.

What other changes do I need to make in order to have my app use a
different welcome file?

Thank you,
-Russ

Re: Struts2 GWT and classpath

[Henry]

You're probably getting a classpath problem.
Can you confirm its a classpath exception?

What's the error on the Development Mode window printing?

In the
Run->Debug Configurations...->g(oogle) Web Application
window there is a Classpath Tab
Make **SURE** that under the
User Entries Tree you have
"src"
This can be added via Advanced...->Add Folders
Yes, you add "src" to your classpath - this is strictly for GWT

Cheers,
Henry

Re: Suggestions for dealing with Timers

[Vitali Lovich]

The way I would do it would be:

Timer t = new Timer() {

  public void run() {
 // do one pass of the sort
  }
};

// Schedule the timer to run once in 5 seconds.
t.schedule(interval);

where interval is how frequently you wish to animate.

Remeber - javascript is single threaded.  There is no sleep mechanism.

Using a widget that requires constructor args

[Lorenzo]

Hi all,
can someone put an example of how using a widget that requires
constructor args in UiBinder?

I tried starting from the (very poor) documentation, but I couldn't do
it

I'm a newbie of GWT...

Thanks,
Lorenzo

Suggestions for dealing with Timers

[Sean]

I"m trying to do a visual sort. Imagine a bubble sort where you see
the items move from one bucket to the next. The way I would move them
visually is use a Timer with an AbsolutePanel and move them up.

However, I wouldn't want to move the next guy until my last one has
finished animating. If I do that, then everything will animate at once
making a big mess that ends up correct, but you can't see the process
happening clearly.

What I would want is, on the timer finishing, I'd like to do a
CallBack and say, I'm done, u can do the next one.

What's the correct way to handle this? a While(Timer!=null){sleep}
type thing or somehow fake an AsyncCallback or some other way?

Thanks in advance for your suggestions!

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[ckendrick]

@Tercio I'm not able to follow the distinction you wish to make
between "behavior" and "functionality", but in terms of what the Java
language calls an override, yes SmartGWT supports it.  Demonstrated
here among many other places:

   http://www.smartclient.com/smartgwt/showcase/#grid_appearance_hilite_add

As far SmartGWT's free vs commercial breakdown is exceeding the
simple: the commercial versions include Java Server functionality.
It's explained clearly here:

   http://www.smartclient.com/product/

We also make a nice clean, clear distinction in the showcases.
Everything in this one is free:

   http://www.smartclient.com/smartgwt/showcase/

This one has commercial functionality:

   http://www.smartclient.com/smartgwtee/showcase/

There is no "mystery" or "risk" regarding what is free and what is
not, or whether it's useful.

Some other mis-statements in this thread:

1. the free version of SmartGWT supports databinding as well.
Approaches are covered here:

   
http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/docs/ClientDataIntegration.html

2. someone mentioned "already having" a server.  SmartGWT's server-
side functionality integrates with any pre-existing server-side
functionality and provides features that don't exist in any server-
side library, so it applies regardless of whether you have a server or
not.  Two examples:

Client and server-side validation driven from a single definition, so
you don't have to set up validation logic in both places:

   
http://www.smartclient.com/smartgwtee/showcase/#data_integration_form_validation

Automated aggregation of client-side requests into a compound request
to make transaction handling easier, cut down on HTTP requests and
simplify the re-use of data services:

   http://www.smartclient.com/smartgwtee/showcase/#row_drag_save

And a deeper explanation of how SmartGWT's server-side features apply
even if you have a pre-existing persistence system and business logic:

   
http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/docs/FeaturesCustomPersistence.html

OK, that's it from the misconception police for today :)

I'd really recommend adding gin to your toolkit. It'll make all this stuff
much easier.

Are you using the gwt-presenter framework? If so, inside your presenter:
display.addToList(word);

So you want a sub-view? Create a "Rate This Word" event. Have a RateThisWord
presenter listen for the event and popup a RateThisWord view.

No. Way too complicated. Keep the VerticalPanel and have your view add words
on request from your presenter.

I'd flatten this into a setData call inside an iterator over dates.
(for i = 0; i < dates.length(); i++) {
  setData(dates(i), titles(i), definers(i)...);
}

Somebody is going to have to iterate over those arrays. Your presenter knows
that they're arrays. Hide that info from the view; there's no reason it
needs to know those details.

and then create each item, but not new views, and add them to

So? The event keeps track of the source of each event. You'd need those
events anyway. The events fire a message to the Presenter which then updates
the Model.

In the presenter? That's correct.

Probably not as awkward as you think, and definitely easier to test.

Re: Supported Browsers

[R.Domingo]

Thank you all for replying!

My question was triggered about the news flash that google will stop
supporting IE6 and some other older browsers as described on:
http://googleenterprise.blogspot.com/2010/01/modern-browsers-for-modern-applications.html

But it seems this has no immediate impact on GWT (at this time...).

Co-existing 1.7.1 projects and 2.0 projects

[Pieter Breed]

Hi,

Our team have several version of our software going at the same time.
The current version runs on GWT 1.7.1; our next version will maybe
ship with GWT 2.0 so we are trying to do the upgrade. We have
installed the new google eclipse plugin, but now we can't get our
1.7.1 apps to work anymore in hosted mode. It keeps on trying to load
the browser plugin system of GWT2, which obviously wont work.

I can't find the old plugin which I will happily use, can somebody
here maybe point me to a mirror of it? Is there something else that I
am missing? I've tried to remove the hosted.html file; it has no
effect.

Regards,
P

Re: Some question about Serialization tricks...

You don't *have* to use IsSerializable. Serializable is also supported. See

http://code.google.com/webtoolkit/doc/latest/FAQ_GettingStarted.html#What_browsers_does_GWT_support?

Seems a bit out of date though, as I've heard that only the latest
Opera version was supported (which means Opera 10.x nowadays); and
Firefox 3.6 is obviously supported (I'm not sure unit tests are being
run in Firefox 3.6 though, but as long as it doesn't break compat'

You're right, I'm gonna redo all my views with UiBinder, it'll be a good

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[Tom Schindl]

Though many people think that Overloading/Overwriting and JSNI don't
really fit together.
I think they do if you are a bit creative.

If you are interested in how I solved this problem for QxWT you should
take a look at this series of posts.

[1]http://tomsondev.bestsolution.at/2010/01/05/background-to-qxwt-and-gwt-generator-integration/
[2]http://tomsondev.bestsolution.at/2010/01/10/qxwt-explained-part-2/
[3]http://tomsondev.bestsolution.at/2010/01/12/qxwt-explained-part-3/
[4]http://tomsondev.bestsolution.at/2010/01/15/qxwt-explained-part-4/

The overloading/overwriting use case is discussed in [3]. I have no
deeper insights in SmartGWT but I guess writing something like this is
possible for their set of widgets as well (Probably one can extract
the code I've written for QxWT and make it useable to any JSNI-Wrapper
and even improve the functionality e.g. calling back to JavaScript
without writing any line of code, ... a rather advanced example can be
found here [5]).

BTW QxWT is completely free - everything is dual licensed under EPL and LGPL.

UiBinder and abstract class

[damians]

Hello,

I've got a problem and i googled lots of pages to see if anyone got
the same problem but i didn't find anything.

I've got class AbstractDialog that extends DialogBox with some
standart buttons like OK CANCEL that are bound by UiBinder. I've got
another class that extends AbstractDialog with another declarative xml
file, that contains only the main content of that DialogBox.

When am trying to lunch application i got this error:
Rebinding .UiBinder
  Invoking com.google.gwt.dev.javac.standardgeneratorcont...@a51c3c
Method 'ok' can not be bound. You probably missed
ui:field='okButton' in the template.

Method ok and UiHandler for button okVutton is declared in
AbstractDialog. From class that extends AbstractDialog the UiField is
not visible. Am i doing something wrong or i just didnt saw any
information that you can not extends an object tha got his own
UiBinder and extended class got their own UiBinder as well.

My code:

AbstractDialogBox.java

public abstract class AbstractDialogBox extends DialogBox
{
private static AbstractDialogBoxUiBinder uiBinder = GWT.create
(AbstractDialogBoxUiBinder.class);

interface AbstractDialogBoxUiBinder extends UiBinder
{
}

@UiField Button okButton;
@UiField Button cancelButton;
@UiField Label emptyLabel;
@UiField VerticalPanel main;

public AbstractDialogBox()
{
setWidget(uiBinder.createAndBindUi(this));
setStyleName("oe-DialogBox");

okButton.setText("OK");
cancelButton.setText("CANCEL");
}

public void setContent(Widget content)
{
main.add(content);
}

@UiHandler("okButton")
void ok(ClickEvent e)
{
onOK();
}

@UiHandler("cancelButton")
void cancel(ClickEvent e)
{
onCancel();
}

public void keyPress(KeyPressEvent event)
{
if (event.getCharCode() == 13)
onOK();
else if (event.getCharCode() == 27)
onCancel();
}

public abstract void onOK();
public abstract void onCancel();
}

AbstractDialog.ui.xml

http://dl.google.com/gwt/DTD/xhtml.ent";>
















LoginOptionDialog.java that extends AbstractDialog

public class LoginOptionDialog extends AbstractDialogBox
{
private static LoginOptionDialogUiBinder uiBinder = GWT.create
(LoginOptionDialogUiBinder.class);
interface LoginOptionDialogUiBinder extends UiBinder  {}

@UiField Image icon;
@UiField Label descIp;
@UiField TextBox ip;
@UiField HTMLPanel content;

public LoginOptionDialog()
{
super();

setText("Login options");

descIp.setText("Server IP:");
ip.setText("Enter ip");

setContent(content);
}

@UiHandler("ip")
public void press(KeyPressEvent event)
{
keyPress(event);
}

public void onCancel()
{
// restore ip text from application context
hide();
}

public void onOK()
{
// set ip in application context
hide();
}
}

LoginOptionDialog.ui.xml

http://dl.google.com/gwt/DTD/xhtml.ent";>


 
  
   



   
  
 




Enviroment that am using to launch it:

public class Application implement EntryPoint
{
private LoginOptionDialog loginOptionDialog;
private Button optionButton;

public void onModuleLoad()
{
   optionButton = new Button("Options");
   optionButton.addClickHandler(new ClickHandler()
  {
   public void onClick(ClickEvent event)
   {
   loginOptionDialog.setPopupPosition(optionButton.getAbsoluteLeft()
- 100,
 
optionButton.getAbsoluteTop() - 60);

   loginOptionDialog.show();
   }
  });
   loginOptionDialog = new LoginOptionDialog();

RootPanel.get("optionButton").add(optionButton);
}
}

Re: Building GWT from source

[Karan Bhatnagar]

I have intentionally not set CLASSPATH, as
http://ant.apache.org/manual/install.html#classpath says so.
Thus I feel it is wrong to specify classpaths using ant argument -lib
path-to-tools-subdir-1 -lib path-to-tools-subdir-2

Re: UiBinder Templates - Adding a series of HTML elements

[damians]

This is normal  creates that.
 it is like .

Try to do :

* DateBox.ui.xml ***


 
 
 
 
 



* MyLayout.ui.xml **




   Leading Stuff 
  
   Trailing Stuff 
   
 




Be carefull of padding and spacing for those tables becouse am sure
you dont wana see the difference in paiting the cells of outer table
and inner tables. Second important thing is the size of that inner
table columns. If this is a date so you are sure that the fileds got
fixed length so you can do like this:

* DateBox.ui.xml ***
...
 
 
 
...

and

* MyLayout.ui.xml **
...
 
...

If you want some padding and spacing you need to change the width
attribute in MyLayout.ui.xml to proper value.

Building GWT from source

[Karan Bhatnagar]

Hi,
 I am an ant newbie. I am trying to build GWT from source following steps as
mentioned at http://code.google.com/webtoolkit/makinggwtbetter.html
 I am facing problem doing that and could not get solution in ant forums.

 Now when I invoke ant from trunk directory, it first says that a file is
duplicate.
BUILD FAILED
/home/karan/work/gwt/trunk/build.xml:91: The following error occurred while
executing this line:
/home/karan/work/gwt/trunk/build.xml:27: The following error occurred while
executing this line:
/home/karan/work/gwt/trunk/build.xml:54: The following error occurred while
executing this line:
/home/karan/work/gwt/trunk/dev/build.xml:107: The following error occurred
while executing this line:
/home/karanb/work/gwt/trunk/common.ant.xml:148: Duplicate file
org/apache/COPYING was found and the duplicate attribute is 'fail'.

When I re invoke ant without ant clean, it fails to find classes in tools
directory, for example it says:
compile:
[gwt.javac] /home/karan/work/gwt/trunk/dev/build.xml:199: warning:
'includeantruntime' was not set, defaulting to build.sysclasspath=last; set
to false for repeatable builds
[gwt.javac] Compiling 138 source files to
/home/karan/work/gwt/trunk/build/out/dev/bin
[gwt.javac]
/home/karanb/work/gwt/trunk/dev/core/src/com/google/gwt/dev/ServletValidator.java:21:
package org.mortbay.jetty.servlet does not exist
[gwt.javac] import org.mortbay.jetty.servlet.ServletHandler;
 {Many such errors}

I reinvoke ant, specifying -lib /home/karan/work/gwt/tools/lib/jetty, then
jetty package issue is resolved, but rest packages continue giving errors.
[gwt.javac] /home/karan/work/gwt/trunk/dev/build.xml:199: warning:

package org.apache.commons.collections.map does not exist
[gwt.javac] import org.apache.commons.collections.map.AbstractReferenceMap;

Why do I have to manually give lib path, why can't ant get it by itself as
the guide makinggwtbetter says. I am also mentioning system info below for
any hints:
 Ant is in home/karan/Downloads/
ka...@karanb:~/Downloads/apache-ant-1.8.0RC1$ ls
INSTALL  KEYS  LICENSE  NOTICE  README  WHATSNEW  bin  docs  etc  fetch.xml

 ant is installed properly as I see:

The environment variables are set as :

 The directory /home/karan/work/gwt contains tools and trunk subdirectories.

Question regarding presenter in MVP pattern

[gugguson]

Hello.

I'm creating an gwt app which will enable the user to enter recipes.
I have a presenter with all the basic information like description,
directions etc. which is defined like this:

  public interface Display {
HasClickHandlers getSaveButton();
HasClickHandlers getCancelButton();
HasValue getRecipeTitle();
HasValue getDescription();
HasValue getDirections();
HasValue getServings();
HasValue getTime();
HasValue getCourse();
Widget asWidget();
  }

What I'm going to add to this is the recipe lines which are basically
pair of the ingradient and the amount.  What is the preferred way of
adding lines to this interface when there can be x many lines?

One method would be to do similar to the gwt samples and add two
lines, one with the ingradients (list of strings) and other with the
amount (list of double).  The other method would be to create a class
which would contain the recipe lines with all information.  If I go
that route should I have the class in the presenter package?

Regards,
Johann

Some question about Serialization tricks...

[BM]

Hi, folks.
I have a little question that I haven't figured out myself (mea
culpa). Since GWT requires IsSerializable, how better I can avoid
hassle with duplicating redundant Java Beans? The way it works for me
now: one JavaBean is for database, another is for GWT, but both of
them are identical (GWT's one IsSerializable — that's the only a
difference so far).

I will explain you how I am doing now (not sure it is best way, but it
works so far). For example, suppose I have a completely separated
library, called "Database Operations". It looks like this:

DatabaseOperations op = new DatabaseOperations(jndiStringOfJDBC);
List hellos = op.getABunchOfHellos();

Now, the code above will return me a list of HelloBean that has a
method .getHelloWorldText() for example. So far, so good. Now, in
order to display these beans from the GWT callback in the javascript
client, I need make sure HelloBean implements IsSerializable and its
source is in GWT tree, otherwise GWT Compiler will complain and fail.
Bo!, but that's _another_ project with _another_ namespace etc
etc. So what I do is simply create a stupid clone of HelloBean for GWT
that implements IsSerializable and then import HelloBean-not-
serializable to HelloBean-that-is-serializable. I don't like this way,
because if I changed something in the service, I have to change a lot
of stuff elsewhere etc. It is also redundant beans... OTOH, I can not
find how to avoid this either... :-(

So the question is: how I can get rid of these redundant beans, having
my HelloBean made once and forever made or where to RTFM about this,
since I can not find any doc regarding this?

Please note, I don't use ORM due to my own point of view that ORM
(Hibernate, Top-Link etc) is just a plain wrong idea for actually
amplify your hassle, rather then solve it. So I have no problem to
twist my JavaBeans in any direction, basically. I am fine storing in a
Database any POJO that implements anything (Serializable,
IsSerializable or nothing at all).

P.S. I am using NetBeans for the development, if this would help.
Probably not.

Re: Ext/GXT/ExtGWT v2.1.0 vs. SmartGWT v2.0

[Tercio]

Nope, SmartGWT is a wrapper to SmartClient JS Library.


ckendrick and I have different understandings about override ... :-P
We already discussed this some time ago ...

SmartGWT you can't override it's functionality, just it's behavior.

SmartGWT is more feature rich than GXT, but I don't like their
licensing terms, I prefer GXT one, not only because the price, but the
features, we just need a UI framework, the server we already have one.

Difference in FF and Chrome GWT 2.0

[dinosaurus]

I'm evaluating GWT 2.0. I've created a very simple application (see
below).
I execute it from Eclipse GWT 2.0 plug-in.

DockLayoutPanel p = new DockLayoutPanel(Unit.EM);
p.addNorth(new Button("north"), 2);
p.addSouth(new Button("south"), 2);
p.addEast(new Button("east"), 2);
p.addWest(new Button("west"), 2);
p.add(new Button("center"));

RootLayoutPanel rp = RootLayoutPanel.get();
rp.add(p);

Chrome displays everything correctly while Firefox displays some
clutter (I'm not talking about IE).
Could anybody explain what happens?

Thanks in advance

Re: Can't remove 0 index in ArrayList

[Martin Trummer]

I think you should take some time to find out what the problem is/was.

it's quite unlikely that something in the GWT code changed, so that
such a simple thing would stop working.
Maybe you just had different data before.
Thus it may be an indication that you got something wrong in your
code - difficult to say what when you can't reproduce it.

maybe you got some of your hashCode/equals functions wrong which
could lead to strange behaviour like this.

however, if it's a project that's not critical or if you
just feel fine with this, don't waste your time :)

Re: Is it possible to detect if a popup (opened by Window.open(..) ) has been closed?

[darkflame]

thanks, but I'm affaird I wasn't clear enough :(

I meant a popup window, not a popup panel. (that is, an actual
separate browser window triggered by a Window.open), and not a
internal PopupPanel within the same window.

Sorry for the confusion.

Hi,

popup.addCloseHandler(new CloseHandler() {
@Override
public void onClose(CloseEvent arg0) {
// do something on close
}
});

if you use eventbus you may create your own PopupClosedEvent and onClose do
:
 eventBus.fireEvent(new PopupClosedEvent())

Is it possible to detect if a popup (opened by Window.open(..) ) has been closed?

[darkflame]

I'm integrating a OpenID system into my site, and for part of it, I'm
triggering a popup to login to various openID providers.

This popup is opened by a simple;
Window.open(url, "_blank",
"menubar=1,resizable=1,width=480,height=400");

Is it possible to know when the user close's this popup? Either by a
listener, or (if necessary) by checking periodical for the window's
existence.

Thanks,
Thomas

Re: Can't remove 0 index in ArrayList

Yeah, but the thing is that code was working fine prior to gwt 2.0, so I

Anyway I also tried a simple example like yours and it was working fine, so
I just gave up finding a solution to a problem that I alreay resolved by
doing the alternative way.

Re: Some general questions

[vdimitrov]

Thank you for your replies!

It means that I already have my widgets implemented and I was
wondering if it's a good idea to convert them into xml.

> Try to always do a single call (just return an object with 2

Perhaps that's the best approach, although I will need the count
property just once, which will result in 2 remote methods (one with
the count and one with only the results). I'll аlso see the benefits
of a command pattern.

Thank you!

Re: Can't remove 0 index in ArrayList

[Martin Trummer]

seems to work for me - here's a little test:

  List list = new ArrayList();
  list.add(6);
  list.add(7);

  list.remove(0);
  list.remove(0);

after that the list is empty again.
tested in development mode with gwt 2.0.0

just a guess: make sure, you call the right function
remove is overloaded.

so if you would call:
  list.remove(new Integer(0));
then nothing would be removed, because there's no integer
object 0 in the list.

[Stine]

Hi!

I am trying to introduce Gin in my GWT project and have added



in my gwt.xml.

I am being told that I am missing the above inherits statement in my
gwt.xml when I try to create an injector though:

import com.google.gwt.inject.client.Ginjector;

public interface IMGinjector extends Ginjector {
IMStatusView getIMStatusView();
}

Has anyone experienced anything like that?

Thanks,
Stine

Javascript errors GWT 2.0 / Firefox 3.0

[rmuller]

I am using GWT 2.0 and Firefox 3.0.17

I get these two errors, reported by the Firefox error console:

Error: $entry(__gwt_makeTearOff(null, 7667759, 0)) is not a function
Source File: http://localhost:
Line: 7

and:

Error: Permission denied to get property HTMLInputElement.tagName
Source File: XPCSafeJSObjectWrapper.cpp
Line: 450

Are these GWT bugs?

Ronald

Showcase works OK in the IE6 that ships in Microsoft's Virtual PC "IE
Compatibility" images, so it's likely an issue in *your* IE6, maybe a
plugin?
http://go.microsoft.com/fwlink?LinkID=70868

(also noteworthy, we have an app deployed in production for more than
a year, compiled with GWT 1.5, 1.7 and now 2.0, used *exclusively*
with IE6, and no-one ever reported an issue with our SuggestBoxes)
