Re: Implementing Cut, Copy & Paste in a page having 70 odd widgets

[Karthik Vemuri]

Yup... Thanks.. That's what I was thinking too... I should use the Blur handler 
now since we no longer use listeners

DataGrid GWT 2.4 RC1

[News Club]

Hi:

I want to try the DataGrid in 2.4 RC1 release. I took the CellTable example
and slightly modified it to use DataGrid. I could compile fine but nothing
gets displayed in the browser and no exceptions. I don't know why it is not
working.

Appreciate your help. Thanks.

NR

public class DataGridExample implements EntryPoint {
  private static class Contact {
private final String address;
private final Date birthday;
private final String name;

public Contact(String name, Date birthday, String address) {
  this.name = name;
  this.birthday = birthday;
  this.address = address;
}
  }

  private static final List CONTACTS = Arrays.asList(
  new Contact("John", new Date(80, 4, 12), "123 Fourth Avenue"),
  new Contact("Joe", new Date(85, 2, 22), "22 Lance Ln"),
  new Contact("George", new Date(46, 6, 6), "1600 Pennsylvania
Avenue"));

  public void onModuleLoad() {
DataGrid table = new DataGrid();
table.setKeyboardSelectionPolicy(KeyboardSelectionPolicy.ENABLED);

TextColumn nameColumn = new TextColumn() {
  @Override
  public String getValue(Contact object) {
return object.name;
  }
};
table.addColumn(nameColumn, "Name");

DateCell dateCell = new DateCell();
Column dateColumn = new Column(dateCell) {
  @Override
  public Date getValue(Contact object) {
return object.birthday;
  }
};
table.addColumn(dateColumn, "Birthday");

TextColumn addressColumn = new TextColumn() {
  @Override
  public String getValue(Contact object) {
return object.address;
  }
};
table.addColumn(addressColumn, "Address");

final SingleSelectionModel selectionModel = new
SingleSelectionModel();
table.setSelectionModel(selectionModel);
selectionModel.addSelectionChangeHandler(new
SelectionChangeEvent.Handler() {
  public void onSelectionChange(SelectionChangeEvent event) {
Contact selected = selectionModel.getSelectedObject();
if (selected != null) {
  Window.alert("You selected: " + selected.name);
}
  }
});

table.setRowCount(CONTACTS.size(), true);

table.setRowData(0, CONTACTS);

RootPanel.get().add(table);
  }
}

Re: Implementing Cut, Copy & Paste in a page having 70 odd widgets

[mP]

Suggestion: what about registering a lost focus listener that sets
some global variable when it loses fcous. Your cut/copy/paste buttons
could thencheck the glboal to figure out the last target the user
actually had.

 okay.  right.  i didn't notice the 2nd link was to TreeItem.setWidget
(groups.google.com hid the text *sigh*).

 that calls tree.adopt.  i just went through the code, down to
Tree.java.  Tree.adopt calls setWidget (the base version).  setWidget
then calls onAttach.

 soo... actually... yeah, that might do the trick.  it's... klunky (as
in, it's non-standard behaviour) and thus is going to catch users
out.  i.e. if you _don't_ call that setWidget function, you're
stuffed.

 let me investigate further ok?

 that's the exact [equivalent] class being used, and it's the exact
same class [equivalent] that we've made a 6-line patch to, in order to
fix the bug that has been found [in the exact corresponding equivalent
pyjamas codebase, pyjamas/library/gwt/ui/TreeItem.py].

> The TreeItem isn't itself a Widget, but it can contain a Widget, and
> that contained Widget (think of it as a tree item renderer) can manage
> its own events.

 that's the point, jim: it *doesn't* manage its own events, because
onAttach is never called on the widgets that are added to the
TreeItem.

 thus, anything that's added to TreeItem is completely isolated, as
far as events are concerned.  no onClick, no onDoubleClick, no
onMouseMove, no onMouseUp - nothing.

 i apologise - i realise that it's quite difficult to appreciate that
the pyjamas codebase is the same - functionally - as GWT, to the point
where it's possible to refer developers to the GWT online
documentation rather than have to write our own.

 it's virtually identical to that of GWT, so much so that we can
actually use language translator tools (automatic and semi-automatic)
to port GWT java to pyjamas python.

 but, yes, you've correctly identified the gwt UI class that will have
the exact same bug that was discovered by a pyjamas user.

 and, therefore, _because_ the code is effectively identical, there is
the exact same bug in GWT.

 what the user did was to take the code for onAttach and onDetach in
pyjamas/library/gwt/ui/Panel.py and cut/paste it into TreeItem.py.

 thus, correspondingly, to fix this bug in GWT, you (GWT developers)
need to take the exact same code that is in the gwt/ui/Panel.java
"onAttach" and "onDetach" functions, cut/paste it into gwt/ui/
TreeItem.java and the bug is fixed.

@begin namespace GWT's client/ui widgets on all widgets below
 but first, you need to realise that there _is_ a bug :)  for that,
you'll need to look at the example test-case provided by the pyjamas
user, and port it to GWT.  it's actually very simple: add a CheckBox
to a TreeItem; add the TreeItem to a Tree; add the Tree to a
RootPanel.  add a click handler to the CheckBox, which prints "hello
world" or something.
@end namespace

 click on the checkbox. you'll find that absolutely *nothing* happens.

 that's the bug.

 does that make sense?

Implementing Cut, Copy & Paste in a page having 70 odd widgets

[Vemuri Karthik]

Hi,

I am trying to implement the cut, copy and paste functionality for a
page that has around 70 widgets including text boxes, list boxes,
labels, containers, panels and so on. The cut, copy and paste buttons
are part of these. When a User selects text in some text box in the
page and clicks on copy, the text box loses focus and the copy button
now has it. I need the text to call a method that has some Javascript
call in it like:

$wnd.window.clipboardData.setData("Text",text);

In order for me to do that I need text from the text box and because
the copy button now has it, I do not know where it has been selected
from.

Can anyone let me know if they have done anything similar before using
GWT?

Image from resource in SafeHtmlTemplate

[Micah Caldwell]

I have an image from a ClientBundle resource:
final String myImageUrl = new 
Image(Resources.sSingleton.GetMyImage()).getUrl();

I also have a SafeHtmlTemplates interface:
public interface MyTemplates extends SafeHtmlTemplates {
@Template("")
SafeHtml GenerateCellHtml(String imageUrl);
}

When I call MyTemplates.GenerateCellHtml an exception is thrown because the 
URL output by Image.getUrl(), when the image comes from a resource, does not 
have one of the supported protocols (http, https, ftp, etc.).

Is it possible to use SafeHtmlTemplates with an Image sourced from a 
ClientBundle?  Am I stuck manually building the HTML string in the middle of 
my Java code using SafeHTMLBuilder?

Re: GWT Designer: some panels showing up blank

[Eric Clayberg]

There are two issues here. The first appears to be a issue with WebKit not 
properly rendering CaptionPanels all the time. GWT Designer uses WebKit for 
all widget rendering and simply shows you what WebKit generates (for better 
or worse). We are looking in to possible work arounds as we have had to work 
around numerous WebKit problems like this in the past.

As to the second problem with the VerticalPanel, I tried your examples and 
it worked just fine on my end. I suspect this may be a known issue with 
physical display size as described 
here. How 
big is your physical display? We usually see the sort of 
truncation/clipping you describe when part of the panel is outside the 
bounds that would fit on the physical display. This is a know OS limitation. 
Using a larger display (either physical or virtual) can solve the problem. 
An even better approach would be to break the panel up into smaller sub 
panels that are each small enough to fit within the physical screen 
boundaries.

Singleton instance in RPC AsynCall with two or more RPCs

[Miguel Ruiz Rodriguez]

Hi everybody,

I´m using a solution that use a Singleton pattern to create and
AsynCall class with the followin code.

public interface GreetingServiceAsync
{


/**
 * Utility class to get the RPC Async interface from client-side
code
 */
public static final class Util
{
private static GreetingServiceAsync instance;

public static final GreetingServiceAsync getInstance()
{
if ( instance == null )
{
instance = (GreetingServiceAsync)
GWT.create( GreetingService.class );
ServiceDefTarget target = (ServiceDefTarget) instance;
target.setServiceEntryPoint( GWT.getModuleBaseURL() +
"greet" );
}
return instance;
}

private Util()
{
// Utility class should not be instanciated
}
}

public void greetSongMostPopular(Integer size,
AsyncCallback> asyncCallback);


}

So I had to add a new atribute with another Service
(GreetingLoginServiceAsync), so what could I do? Must I set an input
to getInstanceMethod with the name of the rpc service that I want
create? Are there any best alternative to do this?

Thanks in advance.

how to access the "real" session?

[Dennis Haupt]

i tried to save an attribute via an async servlet call to get it later from
another page. i did it like this:

class x extends remoteserviceservlet
...
final Object attribute =
getThreadLocalRequest().getSession().getAttribute(variableName);


but this doesn't work. the result seems to depend on a mysterious something.
i suspect it being the thread itself. if i store something on page a, it's
not visible in page b's session. if i return to page a, it's there again.
sometimes. how can i save attributes in a way that stores them in the "real
session" across all pages?

is the session i get via getThreadLocalRequest() depending in the current
thread? if yes how to get the actual session?

Re: GWT Compiler Errors

[Matthias Rauer]

Yes, you are right,there are some classes you cannot use on client
side. But in this case I ll get another compile exception.

The other team member haven't these problems, that I have :-( They use
Windows 7 64-bit.

Any language that has a nice regex parser could take this string apart
and reassemble it with the contents of a .csv

I'd put my marker on Perl, but when you know that language. every
problem looks like a nail.

Load Testing Tool for GWT

[Benoit Cantais]

Hi,

Is there any easy way to make parameterizable load test for GWT ? I
tried to use JMeter and Grinder. But when i get the generated script
of my test, both of these tools gave me an unreadable request. The
scripts works fine but it doesn't appear to be easily reusable with
different parameters.

Result with grinder :

/* Understandable code */

result = request101.POST('URL_path',
  '5|0|15|http://URLPATH/|AAE01B9BA413A1202D73415F6358B8FA|
net.customware.gwt.dispatch.client.service.DispatchService|execute|
net.customware.gwt.dispatch.shared.Action|...
962170901|...|2|',
  ( NVPair('Content-Type', 'text/x-gwt-rpc; charset=utf-8'), ))

/* Understandable code */

I am not able to find how to put the variables in this result.

For example, i am actually trying to test a login page.

I need two parameters : The login and the password. I would like to
make load test with login/password coming from a .csv (for example)
file, to test what happen when 100 people try to login in
simultaneously.


Thank you for your help. Sorry for my english.

Benoit

Updating a celllist from a JSONP call

[Paul Browne]

Hi,

I have have a celllist in a UIBinder,  when I use JSON to get some
data from a remote server it does not seem to update the celllist with
the data that I have set in cellList.setRowData until I start moving
the mouse for a bit (sometimes not at all if i dont move the mouse for
about 20 seconds), This problem does not seems to happen if I get the
data any other way i.e. load it from code rather that remote server.

I have tried to cut the code down as small as possiable, (statusText
is a label on screen).
I can see that statusText stays "Set Data" so I know the results have
been returned back, but the screen does not update.


-
initWidget(uiBinder.createAndBindUi(this));

statusText.setText("Getting results");

TaskFactory taskFactory = new TaskFactory();
taskFactory.GetTasks(new AsyncCallback>() {

@Override
public void onFailure(Throwable caught) {}

@Override
public void onSuccess(ArrayList result) {
cellList.setRowData(result);
statusText.setText("Set Data");
}});



Taskfactory in the code is based on the JSONP code that is the main
GWT page, I can put the debugger on the line and see that the array
returned contains all the data I expect

Any ideas?

Cheers

Paul

GWT Designer not supported GXT API's

[Ramaprasad Reddy]

 Hi,

I have used Eclipse as a IDE (3.4.2) to develop the GWT Application
using GWT(2.2.0) and GXT(2.2.4) libraries and installed GWT Designer
plug-in in eclipse IDE , the designer plug-in installed successfully.
I have tried to open GWT Entry point class (onModuleLoad) in the
designer view but its closing eclipse IDE instead of opening entry
point class in the designer view. I imported GXT LayoutContainer class
in GWT Entry point class. As per the product documentation GWT
designer supports GXT API's
Could you please let me know if you have any documents which describes
how to design pages with GXT widgets using GWT designer.

Your help is much appreciated.

Eagerly waiting for your reply.

Thanks
Ram

Drop files onto Web Page

[Sean]

I've seen a few topics on this, but most are a few years old at this point. 
I was wondering if there are any ways to drop a file onto the webpage from a 
folder (Windows in this case) and have it upload or prepare to upload much 
like how GMail does it. I've seen a few ways to "fake" it, I was wondering 
if in the past couple of years if it became easier?

Re: appengine connected android project wizard example

[RS]

At last.

The version of beta eclipse plugin available now (late july - early
aug 2011) hasn't worked independently.

Workaround is to install 2.3 plugin and then install 2.4 beta plugin
on eclipse indigo (3.7) not helios.
After installing 2.4beta on top on 2.3, it would have auto updated
what it needs to. Avoid the temptation to point to the beta plugin in
eclipse preferences. Also don't uninstall 2.3 plugin.

With this workaround, the appengine connected android code generated
by the wizard works out of the box.

Re: file upload once again

take a look at the code in http://code.google.com/p/upload4gwt/, its not a

Do proxy objects necessarily reduce client side entity manipulation to functional programming?

[Nick Siderakis]

I want to load a bunch of data to the client, graph it (via Google 
Visualization API), have the user manipulate it (client side only), and 
regraph it...and so on.

I really like the selling points of requestfactory, but I find my self 
between a rock and a hard place.

**When I was using POJOs for domain objects (with GWT-RPC) I could get the 
data on to the client and manipulate it arbitrarily (using 
its mutator methods, which may contain complex logic) and then regraph it. 
 The manipulated data doesn't need to be saved. 

With requestfactory I only see two options:

1. Manipulate the domain proxies on the client functionally, which might 
duplicate behavior that already exists in the server objects.

2. Do the work on the server, which would request a request for each 
manipulation, not a good idea.

I may be misusing requestfactory...

Any ideas?

Running Unit Test Emulating FF3.6

[pedjak]

  Hi,

  I would like to run GWT unit tests using HtmlUnit that emulates
FF3.6, but by looking at the code in RunStyleHtmlUnit class, I have
realized that possible HtmlUnit browser emulations are narrowed down
to FF3, I6, and IE7. Is there any particular reason for that?

  Best,

Predrag

Re: How to use Mockito for testing Async calls?

Code from a @Test method:

doReturn(pesquisaRequest).when(requestFactory).pesquisaRequest();
doAnswer(RequestFactoryUtils.ok(pesquisas)).when(request).fire(RequestFactoryUtils.anyReceiver());

GWT Remote Logging - Logger Name replaced by logOnServer

[Wooi]

Below is the message I got from my apache server...
com.google.gwt.logging.server.RemoteLoggingServiceUtil logOnServer
WARNING: blablabla

I try to check RemoteLoggingServiceUtil, seeing while my logger name
is null it will replaced?

This is my code...
private static Logger log = Logger.getLogger("Test");
log.warning("blablabla");

I expect something like...
com.google.gwt.logging.server.RemoteLoggingServiceUtil Test
WARNING: blablabla

Any advice?

Canvas is a Widget (derives from FocusWidget).
CanvasElement is just a wrapper around the DOM element  (derives 
com.google.gwt.dom.client.Element).
To be precise, CanvasElement is not even a wrapper it is a JavaScriptObject 
which means that you can not create it in Java (by calling a constructor).
Instead, we have to use Document.get().createCanvasElement() which does its 
work by calling a JSNI method.
I want the widget so that I can do all the event handling in Java 
(FocusWidget implements tons of Has*Handlers interfaces).

Re: Create Canvas widget from CanvasElement

[karim33]

Hi Julian,

I work with GWT 2.3 and i just see in the documentation :
(http://google-web-toolkit.googlecode.com/svn/javadoc/2.3/com/google/
gwt/dom/client/CanvasElement.html)

constructor
protected CanvasElement()

It means that you can derive your own class for CanvasElement.
Adding it in a GWT container works for me.

I agree with you : I don't understand why there is also a Canvas
class, and why the constructor is private ?

In my opinion, Google is perfectionnist, and has provided a cross-
browser test class to check if  is supported by client
browser, in order to let the developper to test and take a decision if
there is no browser support. May be that's why thi class exists. I
don't think it's a bug as Thomas says.

Regards

Karim Duran

We know about solutions like that, but we don't like to inject any new 
dependencies into our project.

Unless there are workarounds, we think it should work like we've implemented 
that stuff. Otherwise:  
a) we've done anything wrong, or
b) we found a gwt css compiler bug 

Are there any other hints? :)

Thanks,
Peter

Re: GWT RPC NOT working with Tomcat

[Henkie]

Hi Juan
No, Tomcat standalone.
I'm trying to deploy my app for production.
I have an ant build script to build the war file.
