GWT MULTI MODULES WITH MAVEN PROFILE

[Francesco Izzi]

Hi all,

there is a way to set a multi gwt project with maven profiles?

For examples:

It should be nice have a way to activated profile with -Pmodule1.

in other words the ability to view a module or not depending on whether the
maven profile is activated.

Best Regard,

Converting from MouseListeners to Mouse*Handlers

[ky]

I'm converting all the MouseListeners in an old hobby project into
Mouse*Handlers instead. My old MouseListeners were somewhat complex
and followed this form:

public class TooltipListener implements MouseListener {
some private variables declarations here

public void onMouseDown(Widget source, int x, int y) {}
public void onMouseMove(Widget source, int x, int y) {}
public void onMouseUp(Widget source, int x, int y) {}
public void onMouseEnter(Widget source) {}
public void onMouseLeave(Widget source) {}

private methods here
}

with some code in each onMouse* method. I then added these listeners
like this:

myCustomWidget.addMouseListener(new TooltipListener());


With the new Handler system, I have changed my class to look like the
following:

public class ToolTipHandler implements MouseMoveHandler,
MouseOverHandler, MouseDownHandler, MouseUpHandler, MouseOutHandler {
some private variables declarations here

public void onMouseMove(MouseMoveEvent event) {}
public void onMouseOver(MouseOverEvent event) {}
public void onMouseDown(MouseDownEvent event) {}
public void onMouseUp(MouseUpEvent event) {}
public void onMouseOut(MouseOutEvent event) {}

private methods here
}

Note that the ToolTipHandler class relies on shared private variables
between all the mouse methods. Each method has almost identical code
from before - the only difference are they use accessor methods from
the appropriate event object. I am adding this 5 part mouse handler
like this:

TooltipHandler handler = new TooltipHandler();
myCustomWidget.addMouseMoveHandler(handler);
myCustomWidget.addMouseOverHandler(handler);
myCustomWidget.addMouseDownHandler(handler);
myCustomWidget.addMouseUpHandler(handler);
myCustomWidget.addMouseOutHandler(handler);


Everything works great, but the code is a bit clunky and I suspect
there is a better way to do this. Is there? I'm using 1.7.1 right now,
but I'm happy to take suggestions pertaining to 2.0.

Thanks! =)

Same issue here. Should this be raised as an issue? Good workarounds?

flextable getcellcount and clear issue...

[golfdude]

gwt 1.7...

I have a flextable in which I add a row, clear the table, and then add
another row. The getCellCount does not get reset during the second add
to zero. So the cells get added after the first col count.

Anybody else see this ? I see that this was reported as a bug in 2006
but I still see the issue.

Re: Problem to structure GWT application (problème pour structurer l'application GWT)

[Sripathi Krishnan]

Approach 1 is the way to go with GWT.  See this discussion
thread.


GWT doesn't play all that well with Struts (or any other server side
web-framework). Use the approach if you are stuck with a legacy application
- but otherwise avoid it.

HMVP design pattern? Help!

[Grary]

Hi,

I'm new to GWT development, but the tutorials and project samples I've
inspected have impressed me with the value of using the MVP pattern
(and associated libraries for that.) Great. But now, as regards
planning the development of my GWT app, do I think about separate
parts of a given page each as having its own MVP structure and
coordinating via the singleton eventbus?

For example, imagine using several shopping carts on a page to shop
concurrently, but impose a rule that none of the carts may contain the
same item. Never having done MVP, I'd say that each shopping cart can
have its own MVP structure with item duplication prevented by checking
proposed additions to a shopping cart against all the others via the
event bus.

Any thoughts?

Thanks,

Grar

PopupPanel.center() not working in Firefox 3.5.5

[David T]

Hi All,

I'm trying to use the provided PopupPanel.center() method to center a
popup panel on the screen. This works fine on Opera and Safari
centering the popup relative to the browser window. In Firefox though
it centers the popup relative to the entire page.

I've tried to implement my own center method as follows:

private void center() {
popup.setPopupPositionAndShow(new PositionCallback() {

public void setPosition(int offsetWidth, int offsetHeight)
{
int[] winSize = windowSize();
int left = (winSize[0] - offsetWidth) >> 1;
int top = (winSize[1] - offsetHeight) >> 1;
popup.setPopupPosition(Window.getScrollLeft() + left,
Window.getScrollTop() + top);
}

});
}

public final native int[] windowSize() /*-{
var myWidth = 0, myHeight = 0;
if (typeof(window.innerWidth) == 'number') {
//Non-IE
myWidth = window.innerWidth;
myHeight = window.innerHeight;
} else if (document.documentElement &&
(document.documentElement.clientWidth ||
document.documentElement.clientHeight)) {
//IE 6+ in 'standards compliant mode'
myWidth = document.documentElement.clientWidth;
myHeight = document.documentElement.clientHeight;
} else if (document.body && (document.body.clientWidth ||
document.body.clientHeight)) {
//IE 4 compatible
myWidth = document.body.clientWidth;
myHeight = document.body.clientHeight;
}
return [myWidth, myHeight];
}-*/;

But this doesn't work as the windowSize() method returns 0 for reasons
I don't know.

Problem to structure GWT application (problème pour structurer l'application GWT)

[TalkinJive]

Hi,

I'm new with GWT. I've studied the StockWatcher tutorial. Now I want
to do my application.
But I can't understand how to organize it ???

Which is right (1° or 2°) ?

1°) A GWT application is made of only one HTML page. I have to develop
different Panel inside (for exemple).

2°) A GWT application can be made of a few HTML pages.
In this case (which is right ?) :
1 HTML page = 1 EntryPoint = 1 module ===> I have to create a module
for each HTML page ?
or It's possible to have multiple EntryPoint en multiple HTML pages in
the same module ?

3°) What about an application with GWT and Struts together ?

Perhaps I'm wrong and no proposal (1° and 2°) is right.
Thanx for your adivces.
TalkinJive.

DialogBox not displaying correctly

[TD]

Hi,

I've edited the Starter Project to popup  a DialogBox when I click a
Label.  However, the DialogBox appears all garbled.  A screenshot can
be found here: http://files.ducbase.com/GWT.png .

This is the code I use:

Label configLabel = new Label("Setup");
RootPanel.get("config").add(configLabel);
configLabel.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
DialogBox config = new DialogBox(false);
config.setText("Title");
config.setAnimationEnabled(true);
config.setPixelSize(400, 300);
TabPanel tabPanel = new TabPanel();
tabPanel.add(new HTML("foo"), "Levels");
tabPanel.add(new HTML("bar"), "bar");
tabPanel.selectTab(0);
config.setWidget(tabPanel);
config.show();
}
});

Any ideas?

Thanks!
Tom.

String problem

[Gosia]

Hi
I''ve got small problem. I've an GWT application in which I would like
do something like this

String myString = new String("something");
String otherString = new String(myString.getBytes(),"windows-1252");


I'm writting code in Eclipse, and in code there aren't any problems.
But when I'm trying to run application in Hosted Mode or compile it
show some problems

Line 462: The method getBytes() is undefined for the type String

I know , reason of that is JRE Emulation for lang which doesn't have
those methods.  Is anybody knows how do it in other way (the same
effect but possible in GWT).

Thanks.

says it's installed but complains that the plugin is missing when I
restart - installs only on Chrome (4.0.249.11) for me.
(2) I can create a GWT 2 project, but it fails 90% of the time (the
odd thing is, it does work occasionally) with a variety of errors (not
finding the module or package not matching or class not found)

I'm quite frustrated, but wonder it's just me or my setup. Does anyone
else have this working? I'm using Galileo and am on Vista 64 bit.
Please help.

Re: dynamic Messages/ImageBundle possible?

[kgeri]

[Not sure if my previous post went through, so...
]


For dynamic (string-accessible) message support take a look at this:
http://code.google.com/p/gwt-dmesg



I wrote it because we've faced the same problem a million times now in
our GWT projects and it was annoying :)



Hope it helps, comments and ideas are welcome!

Re: Google Web Toolkit 2.0 RC2 Now Available

[Sekhar]

That was quick, thanks! All the issues I had (error loading module, FF
not working, etc.) are gone; but I'm still having trouble with IE8: it
installs, but keeps saying the plugin isn't installed. I'd uninstalled
in Control Panel as suggested, and the new plugin is on the list now,
but IE keeps asking for a plugin. Anyone else?

Re: GWT Developer Plugin works only sometimes

[Sekhar]

Thanks for raising this, hope Google fixes this soon. Meanwhile,
here's a workaround that's working for me. Say you have a GWT2 module
under com.allurefx.gwt2 and you're trying the sample greet app, then:

(1) Remove the rename-to attribute for the module - when you run the
app, it will create a directory com.allurefx.gwt2.GWT2, with
com.allurefx.gwt2.GWT2.nocache.js
(2) Edit the HTML to load com.allurefx.gwt2.GWT2/
com.allurefx.gwt2.GWT2.nocache.js (rather than the default gwt2/
gwt2.nocache.js)
(3) Edit war/WEB-INF/web.xml to set url as /com.allurefx.gwt2.GWT2/
greet (rather than the default /gwt2/greet)

Not the prettiest way to do it, but something to get going while
Google fixes it.

Re: Making command pattern RPC look like traditional GWT RPC

[Jamie Gennis]

Another thing that I came across that other authors of generator libraries
may also have problems with is testing classes that interact with a
TypeOracle.  I spent a couple hours last night updating my
TypeOracleBuilder
while
moving from GWT 2.0.0-ms1 to 2.0.0-rc1.  I'm not sure what the right
solution is here.  The TypeOracleBuilder and MockJavaResource classes that
are used for GWT's internal tests could be included in gwt-dev.jar for
external libs to use.  Maybe they belong in a new GWT testing jar.  I could
also factor these out of gwt-remote-action and maintain a 3rd party lib in
lock-step with GWT versions.  Or maybe nobody other than me wants this
functionality and it's not worth spending any time on.

Anyone have any thoughts on this?

Problems in sending http request manully by com.google.gwt.http.client.*

[wangfeng]

Hi guys,

I am new in this field and this is a problem when I want to construct
a http request and send it.

Learn form GWT that I can send a request as follows:
   1. String url =
   2. RequestBuilder builder = new RequestBuilder
(RequestBuilder.POST,URL.encode(url));
   3. builder.setHeader("Content-Type", "application/x-www-form-
urlencoded");
   4. String form = "name=aaa&age=13";
   5. builder.sendRequest(form,newRequestCallback() {
   6. .
   7. });

So,what if there is a file input field and the contetn type is
multipart/form-data ? so according to the standard HTTP header format
when sending this kind of form,my solution is as follows :

public void onModuleLoad() {
final TextBox text = new TextBox();
final Button btn = new Button("Http Request Test");

final Label lbl = new Label("");

RootPanel.get().add(text);
RootPanel.get().add(btn);

RootPanel.get().add(lbl);

btn.addClickHandler(new ClickHandler()
{

public void onClick(ClickEvent event) {

btn.setEnabled(false);
String url = 
"http://export.writer.zoho.com/remotedoc.im?
apikey=e13ac14e4b7bd43f8bae584105d39318&output=editor";
String BOUNDARY = 
"---7d4a6d158c9";
url = URL.encode(url);
RequestBuilder builder = new 
RequestBuilder(RequestBuilder.POST,
url);
StringBuffer sb = new StringBuffer();


sb = sb.append("--");
sb = sb.append(BOUNDARY);
sb = sb.append("\r\n");
sb = sb.append("Content-Disposition: form-data; 
name=\"Edit\"\r\n\r
\n");
sb = sb.append(URL.encode("divbutton"));
sb = sb.append("\r\n");

sb = sb.append("--");
sb = sb.append(BOUNDARY);
sb = sb.append("\r\n");
sb = sb.append("Content-Disposition: form-data; 
name=\"content\";
filename=\"1.txt\"\r\n");
sb = sb.append("Content-Type: 
application/octet-stream\r\n\r\n");

byte[] data = sb.toString().getBytes();
byte[] end_data = ("\r\n--" + BOUNDARY + 
"--\r\n").getBytes();
byte[] fileContent=; // the file content

/*
//Logic to write the data to http header,it may 
like this but not
support by request builder:
output = builder.openOutputStream();
output.write(data);
output.write(fileContent);
output.write(end_data);
*/

builder.setHeader("Content-Type", 
"multipart/form-data;
charset=utf-8;boundary="+BOUNDARY);
builder.setHeader("Content-Length", 
String.valueOf(data.length +
fileContent.length + end_data.length));

try {
builder.send();
} catch (RequestException e) {
e.printStackTrace();
}
}

}
);


}

1. The code will fail in compilation ,ERROR:The method getBytes() is
undefined for the type String ? Why does this error happen?
2.How can I add the byte[] to the related field in the http header?

Thanks very much !!!

I18N Date problem

[armogur]

i just trying this new 2.0 rc1 gwit, and have a problem with the
handling of the date (it is actually java.util.Date).

using locale hu, with setting it in my Application.gwt.xml and in the
hosting html.

in my application, which is manages entities, and some entity have
Date type field, i am selecting the date with datepicker on the
frontend ui, and when persisting it in development mode everything is
ok, but when i compile it and deploy it to tomcat, and using this
application in production mode, the persisted date int the database is
one day before what is actually i selected in the browser!
the database in both cases are the same!

could this wrong behaviour is my mistake, or it is the fault of GWT?
can someone confirm this?

Re: dynamic Messages/ImageBundle possible?

[kgeri]

Hi!

In our GWT projects we were faced with the dynamic message handling
problem for a long time, and just recently I had the free time to code
this module:

Dynamic Messages for GWT:
http://code.google.com/p/gwt-dmesg

It does exactly what you need :) Comments and ideas are of course
welcome.

How to use "Add to client bundle" w/ GPE RC1 & RC2

[Jeff Chimene]

Hi,

How does this feature work? The child browse dialog is empty.

I've tried pasting the qualified name of a ClientBundle into the main dialog
box. This yields the error "Missing client bundle type
com.example.MainView$Resources"

FWIW, I've been using the ClientResource & CSSResource since the RC1 debut
w/ no problem.

Cheers,
jec

Widget support for "setUserObject" like TreeItem

[Open eSignForms]

Is there any plan to allow more widgets to support "user objects"
being tied to them so that when events occur on the widget, you can
easily access the object it's related to in the application domain?

I only see this in TreeItem, which is nice, since when a tree item is
selected you can take appropriate action based on the model object
that the tree item represents.

This would a really nice feature it seems to me and could be part of
all Widgets.  That way, even when a CheckBox is checked or unchecked,
it would be easy to access the domain object that knows about this
status so if I have lots of CheckBoxes on a page, I don't have to map
them myself.

If there's such a feature, or a better way to map between widgets and
domain objects, please let me know since I'd love to clean up my
code.

Thanks!

Re: Development Mode Firefox 64bit Linux Issue

Google Web Toolkit 2.0 RC2 Now Available

[John LaBanca]

Hi everyone,

We're getting close! GWT 2.0 SDK RC2 and Google Plugin for
Eclipse 1.2 RC2 are now available for you to try.

Download the GWT 2.0 SDK RC2 here:
http://code.google.com/p/google-web-toolkit/downloads/list?can=1&q=gwt-2.0.0-rc2

The full documentation is still a work in progress, but you can find
instructions for using the updated SDK and Eclipse plugin here:
http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC

We've resolved several issues since RC1 and we feel pretty darn good
about it, but as always, we caution you against using RC2 in production.

Windows users who have previously installed the Google Web Toolkit Developer
Plugin for IE will have to uninstall the old version and
install the new version. This action is required because the file locations
have changed. The RC1 installer required administrative
privileges, but the new installer does not. Use the following steps:
1. Open Control Panel
2. Select Add/Remove Programs
3. Select Google Web Toolkit Developer Plugin for IE and click uninstall
4. During your next attempt to use GWT 2.0 development mode in IE, you will
be prompted to install the GWT Developer Plugin, which will
download an updated installer that does not require administrative
privileges

We are eager to get your feedback, both good and bad, in the Google Web
Toolkit Developer Forum:
http://groups.google.com/group/google-web-toolkit

If you find specific bugs to report, please do so at the GWT Issue Tracker:
http://code.google.com/p/google-web-toolkit/issues

Cheers,
John LaBanca, on behalf of the GWT team

How to position a PopupPanel like google does with error popups in Gmail

[Jaap]

Hi

I'd like to have PopupPanel which I show at the top and in the centre
of the screen when an error occured with a red background, with a
small text like "Oops an error occured please try again"

How do I do this? I'm struggling with getting the right CSS for this.

Thanks

Jaap

Re: Too much is happening (the events are crowding the bus)?

[Arthur Kalmenson]

I agree with Matt here. We also followed the same principle of having
many smaller events, meaning a Presenter will get only the event it
wants to listen to. Using an enum in the event could work too, but
again as Matt pointed out you'll end up having if-then-else trees,
which is hard to read, test and maintain. We are able to reuse some
events by making them generic.

It's going to be up to you, you can either go with a hybrid bus
architecture where classes reach into each other and listen to events
directly, or you can go for a full bus architecture where _everything_
that happens is an event. The latter has the advantage of being highly
decoupled, while the former has the advantage of having fewer event
classes and maybe easier to understand the flow because there is some
coupling.

Re: GWT Developer Plugin works only sometimes

[Riley]

After performing a clean install of Eclipse, GAE 1.2.6,  GWT 2 RC1,
and the new plugin, I'm getting the same issue.  When I create a new
GAE+GWT project with the  plugin and try to run it from dev mode in
firefox, I get the following error:

[ERROR] Failed to load module 'test' from user agent 'Mozilla/5.0
(Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316
Firefox/3.0.10 (.NET CLR 3.5.30729)' at riley_dell1:1609
com.google.gwt.core.ext.UnableToCompleteException: (see previous log
entries)
...


When I deploy the app to appspot, it works perfectly.  Argh!  Thanks
for posting issue 4274, Charlie.  For me, removing the rename-to
attribute from test.gwt.xml doesn't seem to change any behavior.

Am I in trouble?

[Zé Vicente]

Hello all,

I gonna ask a very simple question!

First an affirmation: I am using already the new features UiBinder,
ClientBundle in my GWT project. We did a lot of code using those
features.

Is there any change that the final version of GWT 2.0 will bring me
problems?

Regards,
José Vicente

That is definitely odd. Tell me, after you cycled Eclipse, did you ever
close the Web App Launch View, or once you restarted Eclipse, did you just
open the view and experience this problem?

Development Mode Firefox 64bit Linux Issue

[alexmat]

Dev mode starts up fine. Point firefox at the url, download and
install plugin. Restart... and it asks me to install the plugin again.
It is already installed though. Anyone else seeing this?

Any advice?

Re: ScrollPanel - how to alter scrolling behavior

[jhulford]

You might be able to add a key listener to the scroll panel and use
scrollTop to have it progressively jump down the elements inside the
scrollpanel when the user hits down/up.

Re: GWT Developer Plugin works only sometimes

[Charlie M]

Hi have exactly the same experince.

I have followed it through with a debugger. Whats happening is for
whatever reason its assuming the module name includes the package
path. This is the default unless you override it with the rename-to
attribute in the module config. Since its just using the module name
not the full package path, when it tries to convert it to a path
relative to the class path it won't work.So it ends up looking for the
module in the default package not the one you are actually using.

For me removing the rename to and recompiling works, but it breaks the
RPCs since they uses the module name as the root of their serverlets
url.

Did you open an issue on this?

Re: VerticalPanel insert and index

[Ittai]

Hi,
I tested and saw that when the verticalPanel is created it will
receive the index values of 0 and 1. and if you add by panel.add

a label then you will be able to use 0,1,2
but still I have no way to manipulate the index myself

Re: Google Web Toolkit 2.0 RC1 Now Available

[grandfatha]

After compiling a trivial sample app with the new GWT 2.0RC1 I can see
a lot of functions with empty bodies in my compiled output.

It looks like the following:

function Zh(){}
function oi(){}
function wi(){}
function Fi(){}
function Ni(){}
function Vi(){}
function cj(){}
function mj(){}
function uj(){}
function Cj(){}
function Gj(){}
function Kj(){}


After that there is stuff like this:


function ZCb(){}
function mt(a){}
function Ot(a){}
function Pt(a){}
function Ut(a){}
function Zv(a){}
function RA(a){}
function SA(a){}
function TA(a){}
