Re: MouseOverHandler not called for text of Checkbox
Hi, Why do you not create a composite which will act as the wrapper for the check box and add the mouse handler to the composite. This will solve your problem and you can use that composite anywhere where you need check box in your app. On Fri, Nov 20, 2009 at 6:31 AM, dave wrote: > First and only time I'll bump this, but I've yet to find a solution. > > Adding a MouseOverHandler to the GWT CheckBox widget only fires when > mousing over the checkbox itself from the top, left, or bottom.

Re: listbox that contains widgets instead of just text..
Hello,
You could use MVP to make things much easier and to make client code to
use only objects instead of primitive widgets such as listbox.
Here is some example that could make things more clear:
// this class should be used by your code
class CustomerListBox {
interface Display {
void addListBoxItem(String item);
void removeListBoxItem(Integer index);
//.
Integer getSelectedItemIndex();
}
private final Display display;
private final List customers = new ArrayList();
public CustomerListBox(Display display) {
this.display = display;
}
public void addCustomer(Customer customer) {
display.addListBoxItem(customer.getCustomerName());
customers.add(customer);
}
public Customer getSelectedCustomer() {
return customer.get(display.getSelectedItemIndex());
}
public void go(HasWidgets parent) {
parent.add((Widget)display);
}
}
class CustomerListBoxDisplay extends Composite implements
CustomerListBox.Display {
private ListBox listBox = new ListBox();
public CustomerListBoxDisplay() {
initWidget(listBox);
}
public Integer getSelectedItemIndex() {
return listBox.getSelectedIndex();
}
// and etc
}
CustomerListBox customerListBox = new CustomerListBox(new
CustomerListBoxDisplay());
customerListBox.addCustomer(new Customer("1"));
customerListBox.addCustomer(new Customer("2"));
Customer selectedCustomer = customerListBox.getSelectedCustomer();
and etc
Hope this would help.
Regards,
Miroslav

Re: JSOs, SingleJsoImpl, and Generators
Your thinking makes perfect sense, but if I recall correctly, there's an implementation detail that prevents this exact scenario (that is, generating JSO impls of interfaces). It's a feature we haven't gotten to yet, and it won't make it into 2.0, sadly.

Re: MouseOverHandler not called for text of Checkbox
First and only time I'll bump this, but I've yet to find a solution. Adding a MouseOverHandler to the GWT CheckBox widget only fires when mousing over the checkbox itself from the top, left, or bottom. It does not fire when mousing over the text label or when moving from the text over the actual checkbox. How can I add a MouseOverHandler that will fire when over the label of a CheckBox?

Re: JSNI syntax question - calling Java methods from JSNI
I came up with something that works by making 'javaMethod' static. I
can call it like so that way.
@com.foo.bar.MyClass::javaMethod
This feels a bit like I'm jumping through a hackish hoop simply
because I don't know the syntax that is likely available to me for
doing the job. Any help would be greatly appreciated.

Re: GWT on PlayStation 3 (PS3) browser
I just used this browser test - http://design215.com/browser2.php - on
my PS3 and its browser respond to a lot of IE5, 6, &7 features. I
suspect that since the reported user-agent string is "Mozilla/5.0
(PLAYSTATION 3; 1.00)", none of GWT's IE code is being loaded.
I'll try to figure out how to force my GWT app to always use it's IE
code.

Re: GWT Developer Plugin (GWT 2.0 RC1) crashes FF 3.5.5
The terminate option in the Debug pane will behave just as it has in 1.7 and will terminate you application (thus terminating all open browser sessions). The new Web Application Debug View provides information regarding each browser session that is currently open. Thus is you were connected via FF, Safari, and IE (each with a single open tab) you would see three open sessions, each providing their own debug information. In regards to the FF crash, would you mind responding with more detailed steps so that we can attempt to reproduce it.

Avoiding memory leaks during page/view changes in GWT module
My GWT module switches in different views based on what the user is doing...starting with a login page view, then a main menu view, which itself switches sub-views based on the option selected to work on. When I switch to a new view, I call a "deactivate" method on the view that's being taken out of commission. It basically takes whatever widget comprises its main container (typically a VerticalPanel) and calls clear() to remove all widgets that were added to it. Is that enough, or do I have to worry about other things? I do use my own EventBus (HandlerManager) that panels often connect to, so I am also removing those registrations. And I do the same for my Window resize handler when present. But what about all the clickhandlers and other handlers added to buttons, TextFields, etc. Do these all have to be removed, or will they go away when I clear the main component that contains all of those fields? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

what are you trying to do?
what is the form good for?
does it upload the image and afterwards you want to display this
uploaded image?

Remember, too, that EXTJS is GPL code so you either have to be pure open source or you need a commercial license.

Re: GWT with IntelliJ?
I use IntelliJ and have never used the Eclipse GWT plugin (other than a hello world example long before I actually started creating something real in GWT). I find the GWT facet to be extremely helpful, mostly for code navigation and detecting errors with conventions that normally wouldn't be checked until runtime. For example, it understands that the ID that you pass into RootPanel.get() should have a corresponding element in the HTML page. It also knows the methods for setting the style name on a GWT widget and will let you browse between those IDs and your CSS file. Where I think it really shines is if you use GWT-RPC because it understands the relationships between the client-side async interface and the server-side interface and implementation. What this means is that if you say "go to implementation" on an async method call, it will take you to the implementation of the server-side interface. The navigation works in the other direction, too; if you say "find usages" on the server-side method, it will find invocations of the corresponding method of the corresponding async interface. It may be that the Eclipse plugin has these features too. At any rate, I think those kinds of features are really valuable when it comes to IDE support. -Brian On Nov 18, 2:52 pm, Jason Rosenberg wrote: > I see in the docs that there seems to be special support for GWT in > Eclipse (with the developer plugin). > > I have been using IntelliJ, I'm wondering if I will be ok, or should > really switch to Eclipse. > > IntelliJ does seem to have a GWT 'facet', but I don't think it has all > that the eclipse plugin has. > > What are the main benefits of using the Eclipse GWT plugin? > > Thanks, > > Jason -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT vs ExtJs
The Ext-JS component library is richer than what comes with GWT only. Ext Js have done some nice work to get the JS library available in Java trough the GWT-EXT. You can see that on their website. There's also a EXT-GWT project based on Ext-JS, but you'll need the Js open sources library anyway. So it's no like you need to choose betweed them... Ext-JS is not the same thing as GWT... You can have both !

Re: NT User name
Ben,
You can use NTLM, LDAP, or Kerberos for that. The easiest (for both
you and your users) is NTLM. You'll want to use the Jespa library
(http://www.ioplex.com/). I am not affiliated with them in any way,
but I do use the product. With that, all you need to do is add some
settings to your web.xml file and you will be able to get the username
from your server-side code. Everything you will need is in their
documentation and they have a 60-day trial. After that it is limited
to 25 users. If you have 25 or fewer users, you can use their product
for free.
HTH,
Chad

NT User name
A little stuck on this today, there are some posts on the subject but
the seem outdated.
I'm building a web app using GWT the is running internally on a JBOSS
Server. I need to get the user name of the current user logged into
the XP Workstation (via Active Directory) who is viewing the web
site.
In ASP.NET i would have set IIS to NT authentication and used
request.servervaraibles("LOGON_USER") to get it
I'm having trouble finding out the equivilitent in this framework. Any
guidence would be much appreciated. I just need their user name and
don't need to pass on any security tokens etc)

Re: Support for Streaming Video
it is a complex matter... what do you mean for "streaming video"? A. just to play a video file that reside on a server and it is accessed by HTTP, B. play a real video stream like: 1. RTSP + RTP (ietf standards) stream (i.e. rtsp://mystreamingserver:554/myStream) 2. RTMP (flash technology) stream (i.e. rtmp://mystreamingserver:1935/streamApp/appInstance/myStream) 3. HTTP stream (tricky technology that sends a infinite video file as response) (i.e. http://mystreamingserver:80/myStream) 4. other streaming solution not using an URL (Point 4 solutions require some SDK, mainly ActiveX, which allow to start the playback of a video file by calling method using javascript) On 19 Nov, 14:31, Arthur Kalmenson wrote: > No, you would have to use flash or the HTML 5 video tag for that. > > -- > Arthur Kalmenson > > On Tue, Oct 27, 2009 at 10:24 PM, compuroad > > wrote: > > > Do GWT and AppEngine support streaming video? > > --~--~-~--~~~---~--~~ > > You received this message because you are subscribed to the Google Groups > > "Google Web Toolkit" group. > > To post to this group, send email to google-web-toolkit@googlegroups.com > > To unsubscribe from this group, send email to > > google-web-toolkit+unsubscr...@googlegroups.com > > For more options, visit this group > > athttp://groups.google.com/group/google-web-toolkit?hl=en > > -~--~~~~--~~--~--~--- -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

How to handle image/gif response
Hi all,
I have a question about how to handle image/gif type response on
client side, any suggestion will be great.
There is a service which responds for retrieving image (only one each
time at the moment) from database. The code is something like,
JDBC Connection
Construct MYSQL query.
Execute query
If has ResultSet, retrieve first one {
image = rs.getBlob("img"); //save image into Blob image, “img” is the
only entity in the image table.
}
Then,
response.setContentType("image/gif"); //set response type
InputStream in = image.getBinaryStream(); //output Blob image to
InputStream
int bufferSize = 1024; //buffer size
byte[] buffer = new byte[bufferSize]; //initial buffer
int length =0;
while ((length = in.read(buffer)) != -1) {//read length data from
inputstream and store into buffer
out.write(buffer, 0, length); //write into
ServletOutputStream
}
in.close();
out.flush();//write out
The code on client side
imgform.setAction(GWT.getModuleBaseURL() + "serviceexample/
ImgRetrieve");
ClickListener {
OnClick, then imgform.submit();
}
formHandler {
onSubmit, form validation
onSubmitComplete
??? //handle response, and display image
Here is my question, i had tried
Image img = new Image(GWT.getHostPageBaseURL()
+"serviceexample/ImgRetrieve");
mg.setSize("300", "300");
imgpanel.add(img);
but i only got a non-displayed image with 300X300 size.
}
So, how should i handle the responde in this case?
Thanks,

Component Widget not visible in firefox
Hi all...
I'm taking the first steps on my own after successfully completing a couple
of tutorials and books.
However when I want to test my code on a real server, it does not display in
the browser..When the code is compiled in the hosted browser, there is no
problem. When I press the button
Compile/Browse in the hosted browser, I only see the html contents
displayed: only the Title which is set in the index.html file.
I suspect the javascript file is not found in the browser, but there is no
error / message indicating as such. Where can I find out where it is going
wrong?
This are the contents of the files:

External jars
I've got a library I'm using in a GWT project. I exported it from another project and put it in a /lib folder in my GWT project.

JSOs, SingleJsoImpl, and Generators
Now that a javascript overlay can inherit an interface, so long as it is the only JSO that does, is there anything preventing the use of Generators to define new JSOs? The use case I'm thinking of would be a javascript object that is partially (or entirely) defined by browser specific fields and methods (Moz*(), Webkit*(), etc). Since only one JSO would be generated per permutation, this would guarantee that only one JSO was implementing that interface for any particular permutation. While this can be accomplished by a wrapper class with overridden methods, the boilerplate code (even auto-generated), is lengthy and annoying to maintain for objects which need only a few methods overridden. And more people than me must find the spread of "impl" (impl-itis?) and decorator classes grating on a code-aesthetics level. Does the compilation sequence still prevent this?

Re: Decent development hardware for GWT ?

The number of permutations is the number of browsers your compiling for, multiplied by the number of languages. You can also get more permutations for other reasons, depending on what you're doing. Each permutation takes time to process. The more you have, the longer the compile. There's nothing wrong with lots of permutations, except that for development, you generally only need to compile for one browser and one language at a time. So your dev cycle should involve compiling for only one permutation so that the compile is as quick as possible.

cross site linker in GWT 2.0 RC1 vs trunk
I noticed that the XSTemplate.js file is differs between 2.0 RC1 and
the trunk (specifically r7021). I am wondering what the implications
are.
In RC1, the XSTemplate.js (the cross-site linker template for the
selection/landing js file) loads the target js file with a

Grid + horizontal split panel + form binding
I have a page with grid on top and a horizontal split panel below. Based on what is selected, I show some info in the two panels. The issue is that the form binding doesnt work at all. But if the remove the split panel and directly display the bottom half info, it works perfectly. This case I just display some Labels. Am I missing something. and my knowledge on formBinding also sux. Any good tutorials ? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
