Re: ui:image, image within an anchor or a button
I got the same situation.
Currently my solution is only has anchor in ***.ui.xml image part was
added using code.
eg:
Image myImage = new Image();
monitorOverImage = new Image();
monitorImage.setUrl(IFMResources.INSTANCE.vehicleMonitor().getURL());
monitorOverImage.setUrl(IFMResources.INSTANCE.vehicleMonitor_over().getURL());
Is there any better solution?

I wanted to use an image widget so I can use an ImageResource,
something like this:
!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
ui:with field='res' type='com.test.Test.Resources'/
g:HTMLPanel
g:Anchorg:Image resource={res.add} / Add/g:Anchor
/g:HTMLPanel
/ui:UiBinder
But since neither the Anchor nor the Button can take widgets, I get
the Found widget in an HTML context error.
I've seen posts mentioning the ui:image tag but couldn't find
documentation on how to use it and I couldn't get it to work.
If I do:
!DOCTYPE ui:UiBinder SYSTEM http://dl.google.com/gwt/DTD/xhtml.ent;
ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'
xmlns:g='urn:import:com.google.gwt.user.client.ui'
g:HTMLPanel
ui:image src=add.gif /
/g:HTMLPanel
/ui:UiBinder
It's doing something since it won't compile if add.gif is not under
the right package. However when I see it in the browser, the ui:image
didn't get compiled into an image.
Do you know what am I missing here?
Thanks!

Re: Unable to get upload results from FileUpload
Hi Manuel,
I am not using GWTUpload library. You are right, It is text/xml issue.
It works fine with text/html or text/plain. I already requested server
side team to change it for me.
Thanks for your help.

Note that in this example you are using gwtupload library, which is
not the matter of this issue.
When you use FileUpload in a FormPanel, the only way to realize the
form has been submitted is adding a SubmitCompleteHandler to the form
panel, in this handler you can call the method response.getResults()
which is the html content of the iframe used to submit the form. So,
this is the reason I pointed to use a content-type text/plain or
text/html in the server response, using any other content-type the
call to get the iframe content returns null in many browsers.
You can not use the method response.getText() which is specific for
asynchronous ajax calls using RequestCallback, and this is not the
case.
btw: gwtupload library is able to realize that the upload has finished
not only when the FormPanel executes the SubmitCompleteHandler, but
when the server notifies the client, because the client is asking
continuously to the server to the status progress using ajax.

Sorry, yes, you're right.
Here is a working example:
private final IUploader.OnFinishUploaderHandler onFinishUploaderHandler =

public void onFinish(IUploader uploader) {
if (uploader.getStatus() == Status.SUCCESS) {
STUFF

used as follows:
/*

* ... finishes
*/
singleUploader.addOnFinishUploadHandler(onFinishUploaderHandler);
singleUploader.setServletPath(cgi-bin/jsupload.cgi);
I'm still not sure where your event.getResults() comes from.
Not to belabor the point, but do you have the server error log yet?

Hi Jeff,

Actually server is not in my control. Though I can send request for
log file but it will take some time. And I don't think that there is
any issue on server side. We use the same service call for file upload
in our silverlight client, which we are porting to GWT now, and it
work just fine there.
I guess there is something wrong with the behavior of GWT FileUpload
control. Does it accept/return the response text of type text/xml?
May be it only supports the content type of text/html. Any ideas?

ui:image is just a way of defining an ImageResource within the

added). There's also ui:data to define a DataResource. The main goal
of ui:image and ui:data is that they can be referenced in your

variable using a url() ).

Re: wrapping existing HTML form
I need to wrap an existing HTML instead of creating widgets dynamically, so that end user will have the entire form displayed before initialization of GWT components. But then there is a problem: if you attach RootPanel to an existing div element and then use Widget.wrap ( element ) for the FormPanel and its input controls, you get the exception: java.lang.AssertionError: A widget that has an existing parent widget may not be added to the detach list I've googled about the problem and found out that this exception prevents code from messing up widgets hierarchy; this is totally understandable point, but is there any way to get the job done? For a number of reasons I really need those widgets to initialize from HTML instead of being created dynamically. Any ideas? Either: 1. do not use a RootPanel on an ancestor div of your form (obviously) Even if I initialize the form before RootPanel, I get the same error, but for the form controls. For example TextBox.wrap ( element ) produces the same error when called after FormPanel.wrap ( element ) 2. Reverse the order of the calls: FormPanel::wrap() first, then RootPanel.get(); see issue 3528http://code.google.com/p/google-web-toolkit/issues/detail?id=3528 I saw this one. Completely reversing call order doesn't look good. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Persisting web pages locally
The usual model is a source serving pages, and the source persists the data in various ways. I am writing a note-taking (and other uses) application using GWT. Properly, a lot of the smarts will reside on the server, but I must make choices about persisting the information the user enters. The primary entry is by handwriting. It would be useful if the user could save in a format that displays the writing even when opened on a machine that does not have the smart server, keeping the notes visible, and embedded in an HTML document. I am already experimenting with rendering the writing with PNG images. I'm expecting to save the handwriting data as InkML, and there may be other related information (such as the interpreted text). Are there any approaches using GWT to allow me to save PNG images along with a local copy of a page, so it's readable without the server to interpret it? I would need to fetch the images from the server and them write it all locally. I could have the server do this while connected, or the browser (if that's practical), but I would like a one-file format that could be opened in the browser on another machine and show the writing/PNG. Later I'm thinking of other content as well, so general pointers would be helpful.

Re: GWT 2.0.3: Cross-browser problems still?
On 31 mai, 01:28, Navigateur naveen.c...@googlemail.com wrote: When I came into GWT I thought it was going to be write-once for all browsers. Since I've been using it, I've had all kinds of cross- browser problems, in particular with events and graphics, and sometimes widgets. And I've had to do workarounds (which I still haven't fully resolved) to make it work the same in different browsers. I just wondered if everybody else has had smooth-sailing with browsers or if there are others with similar issues? I haven't had that much issues. I can't say I didn't face any, but they (almost) always had easy workarounds IIRC. The main problem with GWT is that because developers don't see JavaScript they think they don't even have to know HTML, JavaScript or CSS, and sometimes even tend to forget they're coding a browser-base app. Coding in Java means better (or, at least, different) tooling and sharing code with the server (though it's moot as JavaScript tends to come back to the server nowadays). I know this is a vent, but sometimes I wish I had used Flash instead! I've been told that Flash isn't a silver-bullet. Might be browser- engine agnostic (though still depends on the browser's plugin API) but not platform (OS) agnostic. Maybe Google can write clear guidelines for third-party library developers, since some of their libraries with respect to events and graphics seem to contribute to (but are not the only) problem. And treat cross-browser differences as a priority e.g. the fact that the core widget focusPanel doesn't seem to register mouseMove events in Internet Explorer except on the widgets contained on it, but does so fine in Firefox/Chrome. Internet Explorer is so strangely coded (with strong constraints on backwards compat with its own bugs, embedded API, etc.) that it has weird bugs that have to be solved on a case-by-case basis. http://code.google.com/p/google-web-toolkit/issues/detail?id=4985 I hope everything written in GWT works the same in all browsers one day. Given Internet Explorer's release schedule and update rate, you might be dead and buried before it happens.

Re: Persisting web pages locally
Well this is the idea behind Google Gears, allowing you to locally persist data in a little lightweight db.

Updating Google App Engine datastore
Hello, I've just an applications using GWT and GAE. After reading the docs and doing some examples I decided to begin coding but soon I reach something tricky. My application data would be at the GAE datastore. I want to assume that the app will live. Let me explain this: The entities at the datastore will change. This means that some properties would be added and some of them maybe removed what leaves me with a ton of exceptions to handle. Knowing this, which should be the way to update the datastore entities? One by one after a change is made? Should I handle exceptions and then change just the entitie requested? Is there a way to do this cleaner? I've been thinking about how to do this stuff with my actual knowledge and i think that the most logical way to proceed is get the object, remove it from the database, create a new one based on this old object and then persist it again. To sum up the question is about if there's a way to add a property to an stored entitie in the datastore (GAE) easily. I hope you to understand my lines. Any suggestion would be appreciated.

DockPanel - how to maximize center?
Hi, I use the following code to create my screen. I want a MenuBar at the top and that the content in the middle is always centered: pnl = new DockPanel (); pnl_Center = new VerticalPanel (); pnl_Center.setHorizontalAlignment (VerticalPanel.ALIGN_CENTER); pnl_Center.setVerticalAlignment(VerticalPanel.ALIGN_MIDDLE); pnl_Center.setSize(100%, 100%); pnl.setSize(100%,100%); pnl.add (mnb,DockPanel.NORTH); pnl.add (pnl_Center,DockPanel.CENTER); RootLayoutPanel root = RootLayoutPanel.get(); root.add (pnl); However, I noticed the following: The north part of pnl is a little bit heigher than the MenuBar. And: When I add small content to pnl_Center, its heigher than when I add big content to the center. How can I achieve that the north part is just as high as the MenuBar?

Rebar: Gears workers, jdbc, and jpa for GWT
Hi all, I just wanted to share the link for a few modules related to GWT / gears / HTML5 that we've recently packaged as open source at http://code.google.com/p/rebar, which includes: * GWT linker for building (Gears) workers, complete with RPC support * JDBC emulation layer that facilitates testing, * An experimental JPA implementation for client-side GWT (and it works!) We'll be adding deferred bindings for browsers that support HTML5 in the coming month, but right now the suite works nicely with Gears. I think there's a few folks out there that have used it in their projects successfully, so thought it might be a good moment to share with the newsgroup.

Using SliderBar from incubator
GWT 2.0.3 Eclipse 3.5 Mac OS X 10.5 Java 5 Hello, I'm attempting to use the SliderBar in the incubator project. The name of the incubator file I've obtained was called gwt- incubator.jar. My import statement for the SliderBar looks like this: import com.google.gwt.widgetideas.client.SliderBar; I can see the SliderBar, I have the css set up and I can manipulate the values of the slider programmatically, like mySliderBar.setCurrentValue(Double.parseDouble(10)); But I'd like to be able to manipulate the position of the slider manually, by sliding the image with the mouse, like you can do here: http://google-web-toolkit-incubator.googlecode.com/svn/trunk/demo/SliderBar/index.html But when I attempt to mouse over my slider nothing happens. Nothing moves. Clearly I'm missing listener information. If anyone can point me in the direction of finding more information about the use of SliderBar I'd be grateful. For example, is it possible to see the code that operates the SliderBar in the link I've given above?

Re: Persisting web pages locally
I understand Gears allows local storage of remotely sourced web data. I don't know of any way it solves the problem of embedding PNG in a locally saved html file so the file can be viewed on a machine which doesn't have my server installed, and which may not be connected to the network at the time. This is a note taking application at first, with the idea of making the notes 'smarter' in later versions. I'd like to have the notes always viewable just with a browser, just as with any locally saved html file. The notes would be read-only, and not smart, but accessible. So my question is more how to embed (PNG) data presented with a GWT Image widget into a saved html file so it can be displayed in a 'dumb' browser. The Image is how the handwriting is shown, with backing smarts in the full application. Thanks.

Re: Using SliderBar from incubator

Re: GWT Compiler fails with 'Too many open files' error / internal compiler error
Hi, are you on Linux? There's a limit of open files you can have. Google for Too many open files to find a solution. Here's a good page: http://confluence.atlassian.com/display/CONF29/Fix+'Too+many+open+files'+error+on+Linux+by+increasing+filehandles If your parameters are in a normal range before calling the GWT compiler, then there may be a problem with GWT though, because I'm not sure, if it's supposed to use so many open files.

Re: Calling Methode using JSNI failed
You should start by carefully reading the JSNI documentation:
http://code.google.com/webtoolkit/doc/latest/DevGuideCodingBasicsJSNI.html
http://googlewebtoolkit.blogspot.com/2008/07/getting-to-really-know-gwt-part-1-jsni.html
A simple JSNI method looks like this (note the specially formatted

Re: How can I prevent from reloading the page when the reload button on browser is clicked?
It is not possible to avoid refresh(reload) through scripts. The only
possible thing is you could display an alert message through the
browser which provides the User with option to either stay on the page
or leave it. Which is what is done in the CloseHandler in your example
script.
What federico wants to say is you should use history-tokens to save
your states.
Use Refresh, Back, Forward as a feature and not a catastrophe, with
the the help of GWT History support.

Re: Need a way to get width of each column in a Grid
Never mind guys. Figured it out. Just in case there are any searches:
public CellFormatter cellFormatter = new CellFormatter();
public Element cellElement;
and then I made 2 methods that I found very useful within my class
that extends Grid:
public int getColumnWidth(int column) {
cellElement = cellFormatter.getElement(0, column);
return cellElement.getClientWidth();
}
public int getColumnOffset(int column) {
cellElement = cellFormatter.getElement(0, column);
return cellElement.getOffsetLeft();
}
in the getElement function you can specify a row also, but I chose to
use 0 because all my columns in a given row have the same width. Be
wary though, I've noticed it rounds. I used a similar method to get
the total width for the table, and then I subtracted all the column
widths while the borders were set to 0, and the result I got was -3.
So there is slight rounding going on, which is why I found the
getOffsetLeft method of Element so useful since its more accurate for
me to get exactly where something is placed.
Best of luck!

Rob -- Forwarded message -- From: Thomas Broyer t.bro...@gmail.com Date: Dec 21 2009, 8:01 pm Subject: Improving event handling, as initiated in 1.6 To: Google Web Toolkit Contributors Hi Googlers, GWT 1.6 introduced the new event handling, which is really great. It however suffers from some limitations, the one bugging me the most being the difficulty/impossibility to support new DomEvents, such as D'n'D events, ononline/onoffline, onstorage, or browser-specific events (those that can be emulated in other browsers: mouseenter/ mouseleave, focusin/focusout; and those that cannot: onhelp, onselect/ onselectionchange/onselectstart, onmozorientationchange, ongesturestart/change/end, ontouchstart/end/move/cancel, onorientation, etc.) This is because event's sinking is done by DOMImpl using a field of bits, instead of being baked intoDomEvent(using an Impl class with deferred binding by browser). How about, for instance, building it intoDomEvent::Type, so that addDomHandler could call type.sinkEvent (xxx)? Other improvements that I'd like to see happening re. events: - finally accurate (not necessarily 100%-identical cross-browser- wise) support for key/keyboard events (issues 72, 1061, 1529, and 3753, and issue 3640) see alsohttp://groups.google.fr/group/Google-Web-Toolkit-Contributors/t/e7059... - onfocus/onblur on Window (issue 68) - focus/blur event preview (issue 1431) - unsink events when there all handlers have been removed (issue 3619) - allow listening to events in the capture phase instead of only being able to listen to the bubble phase This last issue (3619) cannot be solved without either (as I proposed in comment #3 on the issue): - changing Widget::addDomHandler wrap the HandlerRegistration so that removeHandler() queues a finally command to eventually unsink the event - baking this in HandlerManager, eventually by introducing a DomHandlerManager extends HandlerManager to be used by widgets See alsohttp://groups.google.fr/group/google-web-toolkit-contributors/msg/cd4... I volunteer to provide patches, but I need to know what you, GWT team, want and want-not. I'd happily work on sorting those key/ keyboard events out, followed by rework of theDomEvent'ssinking extensibility and issue 3619. -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
[gwt-contrib] CompilePerms and classpath loading problem.
I'm working on a distributed build system for gwt and I seem to have
run into 2 problems.
First problem is related to UiBinder. Once I transfer all the files to
the remote machine (that is src, required jars and result emitted by
precompile step) I changed the classpath context and executed compile
perms as follows:
new CompilePerms(options).run(logger);
where options is an instance of CompilePermsOptions.
the error I get is

If I use same src, libs and precompile result and execute the
following command

everything works just fine Does anyone have any idea why would I
get the above mentioned error?
Second problem is that once I transfer files to the other machine,
where the CompilePerms is executed - once everything is finished the
jar files, which were added to the ClasspathContext using
URLClasspathLoader don't seem to be unloaded even when the context is

Is it possible that some other classloader, within the gwt code, has

This is the primary error. Are you sure that file is showing up on the
remote machine? Before you invoke the compiler, you can try doing a
classLoader.getResource(hr/example/orka/client/panels/MainPanel.ui.xml)
and make sure it's found.
Second problem is that once I transfer files to the other machine,
where the CompilePerms is executed - once everything is finished the
jar files, which were added to the ClasspathContext using
URLClasspathLoader don't seem to be unloaded even when the context is
reverted to what it was before and all the references are set to null.

It's probably the refs in ResourceOracleImpl. We keep them around for
hosted mode refresh to be faster. Take a look at that, describe your use
case, and we can talk about how those things can get cleaned up.

I'm sure that the file is located on the remote machine. I have
checked it manually and the other thing is that once I transfer files
to the remote machine and execute compile perms manually as described
here (http://code.google.com/p/google-web-toolkit/wiki/

com.google.gwt.sample.hello.Hello -workDir work -perms 0 (I adjusted

Well, the use case is basically that I want to have a machine that
will be used for compiling different projects. So, once precompile is
done and all the necessary data are transfered to the remote machine
for compilePerms - the remote machine does the compile perms step and
emits some result. That result is then returned to the client which
sent the data for processing (compilation). That data, which was sent
to be processed, is not necessary on the remote machine, not any more
so it should be cleaned up.

Re: [gwt-contrib] Re: CompilePerms and classpath loading problem.
I just tried
classLoader.getResource(hr/example/orka/
client/panels/MainPanel.ui.xml)
and this worked ok. The resource was correctly fetched.
