GWT RPC with Python

[maksud]

Hi,

I am creating some application for google app engine with *python*. I am
using *GWT* for the client side interface. But how to do RPC calls to
python.

I know Google App Engine java version could do that easily and I tested it
well. But for Python what are the options.

I tried http://code.google.com/p/python-gwt-rpc/ project. But due to lack of
documentation I could not manage it.


Thanks in advance.

Have you tried setTabIndex()? (hint: it might unfortunately break tab
order before firstname and after sex)

GWT 2.0 Tutorial

[eggsy84]

Hi all,

After downloading GWT 2.0 RC2 I thought I'd compile a couple of
tutorials on using GWT 2.0.

So far I have done project creation and declarative interfaces. I'd
appreciate any comments people may want to share:

http://eggsylife.co.uk/category/gwt/

Many thanks,

eggsy

It might very well be a bug in HtmlUnit if that's the runstyle you're
using to run your tests (it's the default one in MS1 and MS2), but
according to this test (from 2.0.0-ms1) it should work (the test isn't
annotated with @DoNotRunWith(Platform.Htmlunit))
http://code.google.com/p/google-web-toolkit/source/browse/tags/2.0.0-ms1/user/test/com/google/gwt/user/client/ui/ButtonTest.java#68

Try running your tests manually to confirm (add "-runStyle Manual" to
the -Dgwt.args sysprop; it'll ask you to open a URL in a browser, just
like with DevMode).

Custom namespaces will not help here, because the browser will
probably ignore the ID attribute again. I will do a few tests, but I
assume that JSON is a bit faster for parsing. Also JSON is easier to
implement, even when not using GWT.

Re: GWT 2.0 Tutorial

[eggsy84]

Hi there,

I think one of the major advantages are that it can vastly increase
development time.

If you have had to work on large projects you can find it might take a
lot longer to code a view. Previous developers that have used JSP's/
Spring MVC/Struts frameworks have all seemed to say that development
time has increased for what should be relatively simply. Using
declarative interfaces it makes designing the interface a lot quicker.

They also allow for team integration. For example you could teach a
designer what widgets are available and they can then design the
interface without having to know anything about the backend of the
system - leaving the backend and 'glue' coder free to work on that.

The declarative interfaces also allow style integration which I will
discuss again making it quicker and easier to design applications.

Hope this helps ?

Re: How can I create spreadsheet using GWT?

[Sean]

Check out a grid filled with text boxes. That's the most basic way. It
won't look very pretty, but it'd work. If you want to make it
"prettier" I would fill the grid with labels that when clicked, turn
into a text box. And when you click off of it, or hit enter or escape,
it takes the text from the text box and fills the label with it, and
then goes back to showing the label.

Re: GWT History Interacts Badly With Non-History iFrame

[Brian]

I'm not sure that I follow completely, but perhaps a different
approach would be to serve up two versions of the help. One would be
under control of GWT and the other would be more static and would be
shown only to search engines. You could probably work out a way that
they would both show the same content so there wouldn't be versioning
issues. Again, I'm not sure I followed well enough to know if this
would help with your problem, but it's a different approach to think
about.

How can I disable context menu in RichTextArea?

[Taimur Mirxa]

Folks,

I have created my own popup menu, which I want to display in RichTextArea,
and it is appearing with right mouse click. my problem is that default
broswer's context menu does also appear along with my menu. is there any
resolution for this?

I have seen lots of examples and code but all of them were disabling
broswer's default menu that shows View Source and other options, I do not
want to disable it, rather my point is to disable the context menu which
appears in text fields or rich text areas.

Incubator GWTCanvas - theoretically faster to Clear() between draws?

[Nerf]

Hiya,

Apologies if this has been asked, a quick search didn't net me
anything. I have been playing around with the Incubator GWTCanvas and
think it's fantastic. I have a decent little functioning framework
now, and have begun to wonder about optimisation.

My question is, if failing to Clear() the canvas between redraws
(frames) causes the new image to be printed on the old image, is it
theoretically more computationally expensive for each pixel of the
second frame to be printed, even if they contain no transparency (full
alpha)? I can see this happening at a base level due to some kind of
alpha diff taking place, though without understanding the
implementation I can't decide whether calling Clear(), filling the
canvas with white/black, or just painting over the old image would be
the fastest.

I don't know if it's likely to affect my performance, but I am aiming
for up to 20 frames a second on a 760x400 canvas, and would like to
make it as easy as possible for the browsers to do their part.

Ubuntu Linux - Firefox 3.5.3 not support Canvas GWT

[Prosky]

Good Evening Mr and Mrs,
I have an important problem in a GWT application during the
execution in hosted mode.
Until a few days ago i worked on an application under windows
envervoiment but in hosted mode
the default browser was Internet Explorer and i know that Internet
Explorer don't support Canvas.
Is true?

So i have installed the last version of Ubuntu Linux and upgrade the
version of default browser that was mozilla 3.0.0 to mozilla 3.5.3 but
when i try to work with the application in hosted mode (in eclipse of
course) the GWT log signals an error about the method getContext('2d')
and say me the another time canvas is not supported.


The application work correctly in hosted mode and in web mode in Mac
Envervoiment; so the problem isn't in the application but in the
configuration of envervoiment.

Anyone can suggest me the solution?

Thank you for answer, Marco.

(Sorry for the not good english)

Re: Cannot install GWT Eclipse plug-in

[Jason Parekh]

Hi guys,

Which flavor of Eclipse are you using?  I recommend the Eclipse for Java
developers at http://www.eclipse.org/downloads/ .

Also, when you re-installed Eclipse, did you try a new workspace as well?

Thanks,

Using JSNI to access external JavaScript function of an external library

[Prashant]

Hi,

I am trying to integrate CKEditor with GWT so I tried following code:


public void onModuleLoad(){
FlowPanel panel = new FlowPanel();
panel.addStyleName("edit-
tools");
panel.add(new Button("Edit", new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
loadEditor();
}
}));

RootPanel.get("content").add(panel);
}


native void loadEditor()/*-{
$wnd.CKEDITOR.replace(document.getElementById("content-block"));
}-*/;


but it didn't work. could anyone point out where i am wrong?

Re: GWT 2.0 Tutorial

[mariyan nenchev]

Hi, yes thanks.
By "JSP's/Spring MVC/Struts frameworks" you mean integrating gwt
with them? So one application is made of many pages(entrypoints). I do not
know how much this slows development, up to now all my projects use single
host page and the view is entirely writen on gwt(but my exp with gwt is not
much). I had to do some integration with struts once and it was nasty.
In general...you are totally right!
Good luck.

GWT + JDO + ArrayList

[Dinis]

Hi,

I'm getting a Null ArrayList in a program i'm developing. For
testing purposes I created this really small example that still has
the same problem. I already tried diferent Primary Keys, but the
problem persists.

Any ideas or suggestions?


**1-Employee class**
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class Employee {

@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName="datanucleus", key="gae.encoded-pk",
value="true")
private String key;

@Persistent
private ArrayList nicks;

public Employee(ArrayList nicks) {
this.setNicks(nicks);
}

public String getKey() {
return key;
}

public void setNicks(ArrayList nicks) {
this.nicks = nicks;
}

public ArrayList getNicks() {
return nicks;
}
}

**2-EmployeeService**
public class BookServiceImpl extends RemoteServiceServlet implements
EmployeeService {

public void addEmployee(){

ArrayList nicks = new ArrayList();
nicks.add("name1");
nicks.add("name2");

Employee employee = new Employee(nicks);

PersistenceManager pm = PMF.get().getPersistenceManager();
try {
pm.makePersistent(employee);
} finally {
pm.close();
}
}

/**
 * @return
 * @throws NotLoggedInException
 * @gwt.typeArgs 
 */
public Collection getEmployees() {

PersistenceManager pm = getPersistenceManager();

try {
Query q = pm.newQuery("SELECT FROM " + 
Employee.class.getName());

Collection list =

pm.detachCopyAll((Collection)q.execute());

return list;

} finally {
pm.close();
}
}
}

gwt- appengine:wrkspc as project hosting root

[Angel Marquez]

Is their any future plans to integrate the google Project Hosting solution
with the gwt/appengine eclipse dev solution?

Example:
I would like to:
1. Create the initial Project via Project Hosting
2. With Eclipse current with gwt and ae check out the new project via svn,
git, merc etc...
3. Work out of this space locally.
4. Test in hosted mode and upload to a Project Hosting root, via the admin
console local(eclipse or command line) or remote(current deploy), which in
turn is a test url (test.project.org)
5. Then after the test cycle push to the live server (projectLive.com)

Notes
Maybe even have the ability to break the team and the project into
manageable components ready to check out during inception.

I would like to do this.

Regards,
Angel

Please point out any flaws in my rationale. Thanks again google for the
growth opp.

Re: Issues using Eclipse and GWT Plugin in Ubuntu Karmic (9.10)

Typically when this happens, the flavor of Eclipse (e.g. Eclipse for Java)

Re: GWT 2.0 Tutorial

[eggsy84]

Hi there,

No I meant traditional web applications which tended to use JSP's with
various other frameworks such as Spring or Struts.

The frameworks would usually be without Ajax requests so new request
new URL and if Ajax was to be introduced they would be with a
Javascript framework such as jQuery or Mootools.

How to listen to events on StackPanel/DecoratedStackPanel?

[Open eSignForms]

Is the only way to handle an event when a tab is selected to create my

handlers that a TabPanel has, which is interesting since I though
these were very similar widgets other than how they display their
tabs.

Any code examples?  Thanks.

I think you want $doc instead of document.

I'm pretty sure 'document' will point to you're GWT IFrames document,

Re: How can I disable context menu in RichTextArea?

[Michael Sullivan]

In your client code somewhere, create this native function:
protected native void blockBrowserContextMenu(Element elem) /*-{
elem.oncontextmenu = function(e) {
  return false;
};
  }-*/;

Then, when you create your RichTextArea, call 'getElement()' on your
RTA instance and pass it to the given native method.
That will block browser context menus for that instance of
RichTextArea and for no other part of your UI.  (Though you may want
to consider
re-implementing Cut/Copy/Paste on your custom menu, as they may be
expected by your users).

How much overhead does including the JUnit module incur?

[Eric]

The advice on the GWT testing page is to have your GWT module inherit
from the JUnit module. However, you shouldn't deploy for production
while still inheriting the JUnit module, because that forces you to
include junit.jar in the war file.  Should the advice on the testing
page be to create a module inheriting JUnit and the production module?

Respectfully,
Eric Jablow

How would the UIBinder and the separation work with custom widgets

[bkbonner]

I'm trying to use UiBinder and have a Composite widget that uses the
PagingScrollTable from the Incubator.  It seems like custom components
will need to have custom parsers written for them to use the
UiBinder.  I'm trying to understand the best use of UiBinder.

I haven't written a lot of GWT apps, so I don't have the experience of
others here.

Thanks,

Brian

building the graphics for my web site

[Jaimon]

hi,
i am pretty new to web development and i have chosen to work with GWT
which i really like. after finishing the business logic phase, i am at
the point where i need to add the graphics to my web site; icons,
images, background.

i have few questions:
1) how i can make my web site to fit any resolution?
2) i could not find any tutorial that explains how to work with images
in GWT, so any advice on how to start working and building the
graphics would a be really appreciated.
3) on the few things that i found about graphics on the website they
were always talking about putting every think in tables, is that the
case also in GWT or i should use panels instead?

please advise
Jaimon

How to automate css resource injections with help of StyleInjector?

[aradzie]

In my GWT application there is a log of CssResource declarations I
created for custom widgets. All of them have to be injected manually
by using familiar StyleInjector helper class. I came up with the
following idiom for this:


final class AppPanelRes {
  public interface Resources extends ClientBundle {
@Source("AppPanel.css")
Style style();
  }

  public interface Style extends CssResource {
String window();

... more methods ...
  }

  static final Resources res = GWT.create(Resources.class);

  // here is the magic piece of code to inject styles automatically
  static {
StyleInjector.inject(res.style().getText());
  }
}


Note that static class initializer injects css styles for me
automatically when that class is being referenced for the very first
time.

However, in the latest GWT2.0 builds that I make from the repository
trunk this code stopped to work correctly for some reason. It still
works in hosted mode, but when I compile and deploy to the production
environment, I don't see any styles.

I think there may be a better alternative to this idiom with static
class initializer injecting styles. Can GWT compiler automatically
create superbundle from all css resources and automatically inject it
when the application starts?

Where did you see that advice? I cannot find it on

1. you generally do not deploy your GWTTestCase (or other test-)
classes (notably due to the fact that you do not deploy your GWT code
as Java classes but compiled into JavaScript)
2. even if you do, you'll never reference them in your production
code, so you won't face the NoClassDefFoundError due to the absence of
junit.jar

> Should the advice on the testing
> page be to create a module inheriting JUnit and the production module?

JUnitShell will synthesize such a module (inheriting both your module –
as returned by your GWTTestCase's getModuleName()– and the JUnit
module). You do not have to explicitly inherit the JUnit module,
unless your GWTTestCase classes are in the classpath when you call the
GWT Compiler (which IMO is bad practice).

By the way, I had added a 1000 ms delay just in case; without it, the
test failed anyway, as the first time, when an expected condition
wasn't met:

junit.framework.AssertionFailedError:  expected=1 actual=0
at junit.framework.Assert.fail(Assert.java:197)
at junit.framework.Assert.assertEquals(Assert.java:94)

...etc

[fker...@gmail.com]

> Could you show us the code of the failing test (around line 51) ?

I cleaned up and simplified the code as much as possible. I created a
boolean attribute, wasCalled. I created a callback; in it, I set
wasCalled=true. (So, this is a poor man's mock object...)

The code up to the failure is:

wasCalled = false;
lv.loginCallback.onSuccess(null);
assertTrue(wasCalled);

wasCalled = false;
lv.loginButton.click();
assertTrue(wasCalled);

The first assertTrue(...) succeeds --so I'm sure the callback works--
but the second fails:

junit.framework.AssertionFailedError: null
at junit.framework.Assert.fail(Assert.java:197)
at junit.framework.Assert.assertTrue(Assert.java:188)
at junit.framework.Assert.assertTrue(Assert.java:183)
at com.fkereki.mvptest.client.LoginViewGwtTest.testLoginView
(LoginViewGwtTest.java:44)
at
com.fkereki.mvptest.client.__LoginViewGwtTest_unitTestImpl.doRunTest
(transient source for
com.fkereki.mvptest.client.__LoginViewGwtTest_unitTestImpl:7)
at junit.framework.TestCase.runTest(TestCase.java:62)
...etc.

By the way, without the first three lines, the result is exactly the
same.

If I run the actual program, the callback does work (and the user
manages to log in).

Thanks again for your help!

How to insert static HTML content

[compuroad]

I would like to know if there is a built in way in GWT to read and
inject HTML content. At least 50% of the site I am planning has static
HTML content that would not benefit from GWT one page model. I am
thinking in building a application that reads the static content using
java.io.File and injects into GWT using the HTML widget.

I would like to know if there are any alternatives.

Thanks,

Wilson

If you have auto-building enabled, I believe that a refresh should look like
a build of the refreshed files.  The as-you-type is a reconcile operation
which is driven by the editor.

We've seen some issues with the java model in eclipse.  I'd go ahead and
file a bug with some repro code, even if it is not consistent.

Re: Using JSNI to access external JavaScript function of an external library

[dougx]

Also, did you realize you can call getElement() on any widget to
obtain the underlying DOM element? It's not always what you're looking
for, but it can be helpful to avoiding having to call getElementById
in your JSNI code.

eg.
native void loadEditor(Object e)/*-{
 $wnd.CKEDITOR.replace(e);
}-*/;

...

FlowPanel panel = new FlowPanel();
RootPanel.get().add(panel);
loadEditor(panel.getElement());

In the module xml file you can specify the compile targets with
something like this:



Which generally works, but I was wondering if there is a way to
specify this to the compiler directly?

Re: How to insert static HTML content

[rjcarr]

I would suggest writing your page in the traditional way and then only
filling in GWT for the sections you need.  You typically do with
placeholders as divs and tds.  For example:


  Here is some HTML ...
  
  Here is more HTML ...


...

EntryPoint {
  RootPanel.get("gwt").add(new Label("Here is GWT HTML ..."));
  ...
}

Re: building the graphics for my web site

[rjcarr]

Hi Jaimon ...

> 1) how i can make my web site to fit any resolution?

This isn't a GWT question.  You'll want to look at other pages that do
this to your liking and investigate how they accomplish it.  It
typically means setting the width of your elements (panels, etc) to
100% in CSS and adjusting things from there..

> 2) i could not find any tutorial that explains how to work with images

You'll probably want to start with the Image class javadoc.  This
represents an image in html .  From there you'll also want to
check out ImageBundle as it is a powerful way to bundle images in your
site.

> 3) on the few things that i found about graphics on the website they

Most all panels in GWT are rendered using tables in HTML, so it is one
and the same.

Good luck!
