GWT 2.8.2 and IntelliJ IDEA

[Mark Fekete]

HI all,

I wonder if anyone is using Intellij and GWT 2.8.2. I 've literally found 
nothing about this topic.


My problem is that whenever i want to start and debug my application, it 
fails because the buildin Jetty-server runs with the wrong version 9.2 
instead of 9.4.

The solution is to use a run configuration with a dedicated Jetty server. 
This is possible  with the "Jetty Runner"-IntelliJ-Plugin which uses Jetty 
version 9.4. 
Unfortunately, when I run this configuration in the context of my GWT 2.8.2 
project, for some reasons the wrong jetty version is started: 9.2 which is 
located somewher in gwt-dev-xxx.jar

Any idea how to fix this? Or I'm forced to switch to Eclipse?

Ben, I unsuccessfully tried a short Google Sheet script function with these two 
lines of code and no luck (ReferenceError: "History" is not defined.) Are there 
more lines of code in your code? Thanks.

GWTMaterialDesign Data Table 1.0-SNAPSHOT is available.

[mark kevin ringor]

Proud to announce that the GMD Table 
 is now available 
for community use! It has been set up as a separate library for the time 
being (could eventually be moved into the GMD 
 library when 2.0 is 
released). All of the features mentioned in my original post have been 
implemented, so check it out for yourself now!

The sample project demonstrates how to use the table showing majority of 
its features. There is also a demo you can look at sampling the 
gwt-material-table-sample 
project. 
InfiniteTable & StandardTable

The data table is based on GWT 2.8.0-SNAPSHOT using java 8 (yay lamdas!).

*It will be great to receive feedback from the community*! Hopefully it 
will improve things for the GMD developers, giving you all a complex data 
table for modern web application development.

You can also note that we are now utilizing JSInterop, giving us direct 
access to the JQuery javascript library (see GWT Material JQuery 
). This is a step 
in the right direction for GMD as a whole and will allow us to do some 
really neat things in the very near future!

 *- Ben Dol*
 *Creator of GMD DataTable*

You can find the demo from the link below!

Re: GWT RPC in GWT 3.0+

[Mark Erikson]

I built an app using GWT and GWT-RPC in 2011-2012, but am currently working 
on a clean-slate rewrite of the client using modern JS (ES6, React, 
Webpack, etc).  I've opted to leave the existing client codebase entirely 
as-is, and have exposed my existing backend APIs over JSON-RPC as well.  
This is allowing me to make some pretty good progress on the new client 
without having to make significant changes to the backend or the existing 
client.  It's also very nice to finally be able to examine my network calls 
in a browser debugger, and since JSON-RPC is language-independent, would 
also make it feasible to call those APIs in other contexts if I ever wanted 
to.

parser doesn't read local code gen-ed in constructor

[Mark Mark]

Hi

I just tried eclipse indigo 3.7 and gwt plugin; The thing is it works 
pretty fine except the designer mode cause sometimes it hangs; As I could 
get it, the code editor doesn't have generated  annotations even working 
with gwt designer; Same windows eclipse indigo gwt designer, as I can 
remember, generates annotations especially above class constructor... Seems 
like parser doesn't read code if it is generated in constructor but if it 
generated in class body only - I tested; 
The thing is because all fields should be declared in class body makes hard 
to develope the mvc dedicated projects which is quite annoying :(

To be more clear I'll demo what code generation type doesn't freeze gwt 
designer and what does; Here it is...

*Code A - Code generation type which freezes gwt designer :*
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.FlowPanel;
import com.google.gwt.user.client.ui.Label;

public class GwtDesignerFreezer0 extends Composite {

public GwtDesignerFreezer0() {

FlowPanel flowPanel = new FlowPanel();
initWidget(flowPanel);

Label lblNewLabel = new Label("New label");
flowPanel.add(lblNewLabel);
}

}

*Code B -  And here is the code generated type which doesn't freeze gwt 
designer : *
import com.google.gwt.user.client.ui.Composite;
import com.google.gwt.user.client.ui.FlowPanel;
import com.google.gwt.user.client.ui.Label;
import com.google.gwt.user.client.ui.Button;

public class MyComposite0 extends Composite {
private FlowPanel flowPanel;

public MyComposite0() {
jbInit();
}
private void jbInit() {

flowPanel = new FlowPanel();
initWidget(flowPanel);
}

}

As you can see, linux version of eclipse indigo doesn't generated 
annotations even working with gwt designer; Still code B is quite 
overloaded I guess if to imagine all fields declarations will be placed in 
class body :(


So my question is... is there a way to make parser refresh ui successfully 
each widget adding in code A generation way cause now if to use code A 
style the *palette*, *properties*,*structure* and *all the rest eclispe gui* 
become freezed each new widged added :P


p.s. if you need some additional information please let me know


Thanks

I tried using your prebuilt SDK but got the following error:
java.lang.NoSuchMethodError:

Is there a way to fix this?

Re: How to create a JavascriptObject object?

[Mark Erikson]

Cool, glad that was an easy fix.

Yeah, this is a good approach.  See https://github.com/richkadel/cesium-gwt 
for a larger-scale use of this technique for wrapping the Cesium.js 3D 
globe library.

Re: How to create a JavascriptObject object?

[Mark Erikson]

Really stupid question: do you have a typo'd 'r' after the open curly?  
It's there in your pasted code snippet, and with JS's automatic semicolon 
insertion, I'm pretty sure it would try to use it as if you'd written 
"r;".  

Also, yes, I think you'd want to use "$wnd.ActualJSObjectName".

Issue with inheriting external libraries and superdevmode

[Mark Wang]

Hey guys, I can use GWT with external libraries, and I can use 
superdevmode, but I seem to have an issue when I try to do both at the same 
time. I'm using this library for oauth2 login 
http://code.google.com/p/gwt-oauth2/ and in my Project.gwt.xml I have 
 and I have the .jar in 
my WEB-INF/libs. 

Everything works fine in production, but when I try to launch superdevmode, 
I get [ERROR] Unable to find 'com/google/api/gwt/oauth2/OAuth2.gwt.xml' on 
your classpath. If I don't include that, superdevmode works fine. My 
Program arguments for my run configuration is "-src src\ -workDir 
"C:\My-Directory" -port 1234 com.package.Class" Any ideas on what to do? 
Thanks!

Re: GWT and SVG, the 125th... :-)

[mark . erikson]

There's two general approaches:

1) Write large JSNI methods that do all the interaction in Javascript
2) Use GWT's JavaScriptObject, subclass the library's objects, and write 
small JSNI methods that wrap individual methods of the JS object.

There's supposed to be better JS interop coming in GWT 3.0, but that's a 
ways off.

There's a number of GWT/JS wrappers out there that you could use as 
examples (Google Maps and Google Earth come to mind).

Re: Introduce SmartGWT for collapse/expand panel for with existing project

[mark . erikson]

Some thoughts on using SmartGWT:

* The SmartGWT developers are VERY insistent that you should develop your 
application using their APIs and structure, as otherwise you are "wasting 
time" and "duplicating effort" they've already put in.  To be fair, they do 
have a bit of a point in that they have designed things to work a certain 
way, and put a lot of time into that structure.
* That said, SmartGWT has enough flexibility that you can somewhat pick and 
choose how you use it, including just using the UI aspects.  For example, 
there's a post in the SmartGWT forum that offers up a subclass of the 
DataSource feature that uses GWT-RPC for communication instead of 
SmartGWT's normal protocol.  I've got an application that uses SmartGWT for 
the client UI, GWT-RPC for communication with the server, and Play 1.2 
(with the Play-GWT module) as the backend, rather than servlets and stuff.
* SmartGWT does add a pretty significant bump to your compiled JS size, at 
least 500K or so.

Overall, I'd say if you have a number of UI pieces you need to use, 
SmartGWT's an option, but probably overkill if you just need one new widget.

Re: GWT 2.6.0-rc1 error compiling

[Mark Donszelmann]

Hi

I have no direct dependency on gwt-dev, but the 2.5.1 maven get plugin refers 
to gwt-dev (and user and servlet) 2.5.1. 

Would that create the problem ?

Is there a newer (published) version of this plugin ?

Re: On extension strategies for GWT applications

[Mark Proctor]

It seems like this is a common request. I wonder if there is anything the GWT 
team can put into the roadmap, that would allow for the compilation of a core 
application. Then the later compilation, aka “linking”, of other gwt code - 
where the user annotates things not to be pruned, so they can be linked against 
later. This way we can write modular applications, with runtime module plugins.

I notice GWT is moving to closure in the roadmap. Closure already has 
capabilities to mark things, to avoid for pruning, for exactly this reason. I 
believe it creates some sort of global table of compiled names, so that when 
the later module is compiled it re-uses those same names. Thus there is little 
extra baggage, from re-loading duplicate things, and no GWT <- JS -> GWT bridge 
is needed. As both Modules, the core one, and the runtime plugin one, 
understands the same names for objects and properties.

SimplePager buttons missing on IE8

[Mark Wengranowski]

Hi Everyone,
 
Just noticed that my app started to act different after moving to GWT 
2.5.1. I use a simplepager on a cell tables to navigate through the 
results. Normally there are the arrow icons that allow you to change 
between pages but they no longer show up and I'm not sure why. It used to 
work great. 
 
The newer browsers work just fine.
 
Anyone have any insight as to what I should try to fix the issue. I've 
tried all of the different ie8 browser modes and nothing seems to 
help(standards, quirks, compatibility).
 
I also use GCharts and it doesn't render properly anymore either. Not sure 
if it's related to the same issue. 
 
Thanks!

Really.  I had not seen that mentioned anywhere.  What sort of approach 
does the current emulated stack implementation use, as opposed to the 
suggested function enter/exit approach?  Is there a relative speed hit 
involved with it too?  Because if so, bring on the new implementation ASAP 
:)

I certainly applaud the obvious time, effort, and care that you've put into 
these improvements, but "45% size and 22-44% execution speed overhead" 
sounds like a rather painful penalty to pay.  I'm not sure that's going to

this affect compilation time?

Re: GWT RPC method in Window.onClose() no longer being called from Firefox

[mark . erikson]

I've actually seen similar behavior in Firefox 17 ESR.  I wound up 
implementing the following horribly disgusting hack as a workaround:

myRPCInterface.logOut(new AsyncCallback() {
public void onFailure(Throwable caught)
{
}

public void onSuccess(Boolean logoutSucceeded)
{
}
});

// HACK!  UTTER, TOTAL, DISGUSTING HACK!
// In the case where the window is closing _right now_, the 
logOut() RPC call often
// does not seem to get sent.  Adding this silly delay loop 
_appears_ to keep things open
// long enough to let the RPC call go through.
// Yes, I feel like an idiot for having to add this.

String s = "";
for(int i = 0; i < 1000; i++)
{
s += i;
}

Re: Open url in new mobile safari instance?: Window.open()

Hi Paul,

Thanks for the sample - it loads the target in the UIWebView. I tried using
a target of "_blank" as well, same result. I might have to just catch
external urls in the native app and launch safari manually,

Thank you

Re: FastButton? Handling touch events for mobile?

[Mark Wyszomierski]

This is great Ashton. Will the press handlers fire when you're scrolling a
page? For example:

   1. User presses down on a button.
   2. User starts to drag downward.
   3. Page starts scrolling (if page content tall enough for scrolling)
   4. User releases outside original button rectangle.
   5. Does that original button still fire a push event?

I tried this on the "Fast Clear" button at the bottom as a test,

Thanks

 I took a quick look at the code you linked to in stackoverflow.  I
 think the code as written has a few problems.

 (NOTE: I'm looking at code I wrote using the Elemental library as
 reference, so some of the calls might be different in the user library).

 a) The code is not filtering touches aimed at the button; it calls
 TouchEvent.getTouches().  You want to call TouchEvent.getTargetTouches() on
 touchstart and touchmove to get the the touches just for your button.  You
 want to call TouchEvent.**getChangedTouches() on touchend to get the
 end touch.
 b) The code does not take into account multitouch.  On touchstart, you
 can check that a single touch is available and bail out if there is more
 than one.  Also, on touchstart, stash away the id of touch, then use this
 in touchmove and touchend to find your touch id in the array that is
 returned (in case the user has touched another finger later on).  You can
 also simplify and check for multiple touches on touchmove and touchend and
 bail again there.
 c) I believe you need to call stopPropagation on touchstart, since you
 are handling the event. I don't see where they call event.preventDefault on
 the touchstart event  You can see that this happens in the click handlers,
 but not the touchstart.

 There is also a simpler way.  If you don't care about dragging starting
 on a button, then you can simply call your click logic in the touchstart
 event (and make sure you call event.preventDefault,
 TouchEvent.getTargetTouches() and  check for single touch) and ignore
 touchmove and touchend.  All the touchmove and touchend stuff is to handle
 the case of allowing dragging to start on the button.

Re: Could not load GWT DMP Plugin

[Mark Bosshard]

Hey Brian

It says "Your computer doesnt support this App" when I try downloading it 
from the appstore. However with drag and drop I get the gwt-plugin working, 
but it crashes with this error "Could not load GWT DMP" Plugin. I added 
0.0.0.0, 127.0.0.1 as well as localhost both in server and local in the 
table of the gwt plugin options. So - no chance on chrome.

I tried firefox. Downloaded the normal today's version of firefox on 
mozilla.org. But: The Plugin is not accepted by Firefox since today we're 
on version 17 and the GWT Plugin is outdated.

This means: Your GWT Plugin is right now only working on Internet Explorer 
as a major windows browser. THATS A PAIN IN THE ASS

TouchEndHandler not firing on ios or android browsers?

[mark]

Hi,

I have a few touch handlers registered on a canvas:

Canvas canvas = ...;

canvas.addTouchStartHandler(new TouchStartHandler() {
@Override
public void onTouchStart(TouchStartEvent event) {
 // works fine
}
});

canvas.addTouchEndHandler(new TouchEndHandler() {
@Override
 public void onTouchEnd(TouchEndEvent event) {
 // never fires?  <---
 }
});

Do I need to do something special to get the onTouchEnd() event to fire?

Thanks

How to set stroke width for Canvas Context2d?

[mark]

Hi,

I'd like to change the stroke width but am not clear how to do this:

Context2d context = ...;
context.setStrokeStyle(FillStrokeStyle ?);
context.strokeRect(…);

I'm not sure how to create a FillStrokeStyle object (or specifically how to 
create one where I can control its width). Anyone know?

Thanks

Have ScrollPanel use 100% height?

[mark]

Hi,

I want to make a VerticalPanel inside a ScrollPanel which takes up 100% 
width and height. I can't get this to work:

  VerticalPanel vp = new VerticalPanel();
  vp.setHeight("100%");
  vp.add(new Label("please...");
 
  ScrollPanel sp = new ScrollPanel();
  sp.setHeight("100%");
  sp.add(vp);

  RootPanel.get().add(sp);

What am I missing? The width seems to be 100%, but the height keeps 
wrapping.

Re: StackLayoutPanel change default behaveeior for header onclick

[Mark Wengranowski]

OK, if i do that i can call event.cancel() wich stops it from changing.

My button that changes the stackpanel to the next stack uses the 
showWidget(int) method and when i call that it triggers the same event 
which is then cancelled. Is there a work around for this? I guess i could 
just put in a switch or something that would detect if it was a header 
click vs a button click?

StackLayoutPanel change default behaveeior for header onclick

[Mark Wengranowski]

Hi Everyone,

I want my stacklayoutpanel to only change stacks when i click on a button 
i've created and not when someone clicks on the header. i.e. i only want 
the stack to change once my validation has passed.

The only way I can see to do this is to copy/paste the 
StackLayoutPanel.java code into my own file and remove the handler that 
gets added to the header. Then use my custom SLP for my ui. 

Does anyone have a better alternative? I'm unable to override the insert 
method for stacklayoutpanel

Re: Firefox 12 release

Roger:

I agree with the opinion that excessive FireFox releases are hard to keep

company for it's stability (the majority also run Windows clients).

UIBinder @Path annotation with arrays

[Mark Trueman]

Hi guys,

If i have an Editor set up which is bound to Object1 using a
SimpleBeanEditorDriver. Object1 contains a list of Object2s. How (if
at all) do i use the @Path annotation to bind the object at a certain
index with the list to a field?

Ive tried a few things, such as
@Path("Object2list[0].value")
@Path("Object2list.[0].value")

but im having no luck.

Id rather not have to provide accessors in my Object1 such as
"getFirstObject2()", but this currently seems like the only way around
this.

Thanks

Mark

guice injecting remote servlet. Error 404 not found

[Mark Diesta]

I would like to use the Guice in my remote servlet but encountered this 
annoying errors.

Before starting my project there is error already.

java.lang.NoClassDefFoundError: com/google/gwt/core/client/JavaScriptObject in hosted mode (only)

[Mark]

I have been developing an app of several thousand lines that has
worked great for weeks.All of a sudden yesterday it stopped loading in
hosted mode (eclipse Indigo, chrome 16.0.912.77, GWT 2.4.0, Google
plugin 3.7) .  As described below, the problem is  in
myProject.gwt.xml that is included for charts (and this used to
work...)

 On loading (hosted mode on jetty), it raises this error:

[ERROR] [reagentcalculator] - Failed to load module

Next step was to try a new project from the GWT template... it
worked!  Okay, so I assumed I introduced a bug.  Over several hours, I
reduced my application down to the following (which you may recognize
as the preamble to the template).


public void onModuleLoad() {
final Button sendButton = new Button("Send");
final TextBox nameField = new TextBox();
nameField.setText("GWT User");
final Label errorLabel = new Label();

// We can add style names to widgets
sendButton.addStyleName("sendButton");

// Add the nameField and sendButton to the RootPanel
// Use RootPanel.get() to get the entire body element
RootPanel.get("nameFieldContainer").add(nameField);
RootPanel.get("sendButtonContainer").add(sendButton);
RootPanel.get("errorLabelContainer").add(errorLabel);
}

Alas, it STILL throws the error!  Tracked down the problem to the line
in myProject.gwt.xml

because I am using google charts in the full app (but not in the small
version above).   gwt-visualization.jar (latest 1.1.2) is copied into
WEB-INF/lib and in project build path.  If I comment out the inherits
line, The code above works fine.

Any ideas?

Thanks,
Mark

Re: How to stall GWT app while it is writing file in background? Timer object??

[Mark]

The whole idea between AJAX is asynchronous operation, the client
continues working while the server does work.  There's no telling how
long the server will take to do its work so a Timer is not the best
option.  Since you want the client to react when the server finishes
you need to pass the workload to the server method and pass an
AsyncCallback object.  In that object you put your Window.open() call
in the onSuccess() method.

Hope this helps.

Re: Code splitting size analysis

[Mark]

Try -compileReport unless that's what you meant.  If there is a lot of
code shared between the different modules then code splitting won't
give you the great results you're hoping to get.  As I believe he
documentations says, code splitting is an iterative process of getting
a compile report , seeing what is included where you don't expect it,
and trying to eliminate that.

Re: gwt gui with no servlet container

GWT doesn't require you to make any server calls so while I've never
done something like that there should be no reason that it cannot be
done.

Re: Creating image from base64

[Mark]

The OP didn't say anything about a specific browser; this is the only
solution I know of for client-side handling of base64 data using GWT.
I would suggest that you make an HTML element containing an "" that points to a servlet that will stream the decoded data
back to you.

Code Splitting Causes Eclipse to Freeze

[Mark Wengranowski]

Hi Everyone,

It seems that when i add code splitting to my program and compile it
Eclipse freezes when it tries to build the workspace.

It gets hung up on the javascript files in the deferredjs folder in
the war directory. They only way i have found to stop this is to
recompile the code without the code splitting.

GWT.runAsync(new RunAsyncCallback() {
   public void 
onSuccess() {

cp.buildMainModule();
}
   public void 
onFailure(Throwable t) {
 //handle 
somehow
   }
   });

Re: transfer Objects between GWT and EJB

I dont know that you can do that directly.  The best way I know of is
to create a pojo to represent the entity on the gwt side and then
translate back and forth between them.

Ideal development platform for GWT/GAE?

[Mark Molloy]

Hi, I currently have one laptop (Windows 7 64-bit) that I use for
everything -- and that's a lot of #&^%.  It is an operational mess.
Now, I've installed MyEclipse 9.0 to develop a GWT/GAE application.
Unfortunately, whenever Eclipse is running, the browsers start timing
out.  E.g., it is impossible to use gmail. :(  Performance of Eclipse
is pretty erratic, too.

I'm thinking that I should get a machine dedicated to development/
testing of my GWT/GAE application. I just want to install Java,
Eclipse, and the plugins I need for the app.

What do people in this group recommend? I want a minimum of
operational maintenance, reasonable performance, and consistent "it
just works" behavior, in place of the constant hanging, re-installing,
head-scratching operational frustration I currently experience. I'd
like to be able to spend my productive time coding and testing
algorithms, not trying to figure out why the layers of software
underneath don't work.

Thanks in advance for your help!

Login Page Options/Opinions

[Mark Wengranowski]

Hi Everyone,

Im finishing my first GWT app and am about to implement the login
page. I've been doing a lot of reading and wanted to get some opinions
on different ways to go about doing it.

The options I have found are the following:

1. Implement the login page into the main application and allow the
user into the next section once they successfully login.

2. Have a separate GWT program for the login that redirects to the
main program once the user successfully logs in

3. Modify the GWT main HTML page to a .jsp and use jsp to set the
session variables and authenticate the user. After successfully
logging in, the page will refresh and the line for the my programs
GWT .js file is written to the page causing it to load.

4. Same as #3 but create a new jsp ad the default page and redirect to
the normal GWT .html page for the program.

Ideally i would like to have my GWT app loading in the background
while the user is typing in their username and password. That way they
won't have to wait for the program to load once they submit their
credentials. Will any of these methods allow me to do this?

Thanks!
-Mark

Re: Reload Place using getWhere()

[Mark Wengranowski]

The code example you provided works perfectly! It reloads the place
without refreshing the entire page.

Instead of making a class i just added it into an onClick event in my
application. Because of this i couldn't figure out how to create the
delegate variable but removing it and the || delegate.confirm(warning)
didn't seem to affect it.

Thanks for your help.

Cheers,

Reload Place using getWhere()

[Mark Wengranowski]

Hi Everyone,

Just wondering if anyone knows a way to reload the applications
current place in the following way:

PlaceController.goto(PlaceController.getWhere());

What happens is that the place controller realizes that it's the same
place your trying to go to so it doesn't do anything.

I could write an extremely long if statement that compares getWhere()
to all of my places but that seems a little long winded to do a simple
thing. ie:

if( (PlaceController.getWhere() instanceof TestPlace){
  PlaceController.goto(new TestPlace());
}else if(...

any simple workarounds would be greatly appreciated. I'm using the
activities and places mvp pattern.

Cheers,
-Mark

Re: SuggestBox with RequestFactory

[Mark Wengranowski]

Thanks. I should be able to figure it out from here but more source
code is always helpful.

SuggestBox with RequestFactory

[Mark Wengranowski]

Hi Everyone,

I was wondering if anyone knows of a source code example that uses
requestfactory, a suggestbox and a dynamic suggest oracle?

I already have suggestboxes that i populate with a list of strings
from a RF call but  need a more dynamic approach for a search tool.
The list is way too long to load all of the answers so i need to
create a suggest oracle that makes an RF call after each key is typed.

All i can find is examples for RPC.

Thanks,
-Mark

Hosted mode memory leaks - am I missing something?

[Mark Allerton]

Hi,

I'm sure I'm not the only person who has ever thought that it might be
possible to use Java-based heap profiling tools to look for memory
leaks in GWT-based applications, but in practice this has turned out
to be a little frustrating because at least based on my naive
interpretation, Hosted Mode leaks pretty much every object that needs
to be invoked from the native side, apparently by design.

So my question is, am I missing something?

To be more specific about what I am seeing, I see many many objects
referenced only via the ThreadLocal "dispatchObjectCache" in
JsValueOOPHM. As far as I can tell based on searching the source code,
objects are only ever put into this cache and none are ever removed.

I have had some (apparent) success with the Eclipse Memory Analyzer,
which allows me to exclude refs via Thread.threadLocals when tracing
from GC roots, but I want to be sure that the references I am
excluding can in fact be ignored (i.e there is not some way that
objects are removed from dispatchObjectCache that has escaped my
attention.)


Thanks in advance

..Mark..

Re: it is not a circular structure

[.Mark]

I have just updated my Ubuntu workstation to 11.10 which has provided
me Eclipse Indigo.  With that I have updated my Google plug-in to the
version for Eclipse Indigo.  I have GWT 2.4.0 and AppEngine 1.5.5.  It
appears things are working better. I am not currently getting the
circular reference exception in the same code.  I am going to test
things a bit more before I consider this issue completed.

ListBox CSS with GWT Clean Theme

[Mark Wengranowski]

Hi Everyone,

I recently started using the newer Clean theme for GWT. I prefer it to
the standard theme but don't like the way that ListBox looks. Is there
any way that i can get the ListBox styles from the Standard theme? I
looked in the generated CSS file but the ListBox style is empty.

Thanks,
-Mark
