Re: Copy to Clipboard
Hi Harish,
I am sorry I was not aware of I had another version of code doing copy/paste
for FF. FF is complicate to support copy/paste due to user privilage
protection. In addition to your code below, you still need to follow FF's
requirement to open privilage of copy/paste:
http://www.mozilla.org/editor/midasdemo/securityprefs.html
If you only want to make your copy/paste working on TextBox, there is an
easier way. You can use below method to get any user selection:
public static native String copyFrom() /*-{
var sel = $wnd.window.getSelection();
return sel.toString();
}-*/;
And then insert the text string you got into your TextBox.

Re: Easy "List to Tree" Drag-n-Drop
It doesn't matter what widget you use for GWT-DnD. The dnd operation can be configured to any AbsolutePanel. So you can put your Tree and List widget in one AbsolutePanel, and create a DropController for your Tree widget.

Yes. That's what I like to do. Could you give an example of retreiving
canvas raw data by GWT instead of JSNI?

Re: GWT and Business Intelligence.
GWT is just a framework that can let a Java developer utilize OOP to develop a web service easily. Under this benefit, it also easily integrate existing server part technology or any other services already opened in internet. Before GWT, there are a lot of 3rd party libraries implemented by AJAX. The web designer who familiar with javascript may not be required to familiar with OO design. So your question is concerned by what type and capability of your human resource in your organization. As we can foresee, more and more web services or javascript libraries will have a wrapper in GWT. There are also bunch of growing libraries that are implemented in purely GWT and opened source. It will minimize the effort to create a new service. GWT's branch, OOPHM, that has already integrated existing web browsers as host browser in development environment. The developer can easily debug and develop consistent solution in variant commercial browser.

Re: Calling RPC from gwt-shell-hosted on netbeans
Did you define your servlet in web.xml that is located in your NetBeans
project directory's web\WEB-INF?
Ex.
Login
xxx.xxx.server.LoginServiceImpl
Login
/xxx.xxx.xxx/LoginService
If you deploy your project by WAR file, you just need to copy WAR to your
tomcat. You don't need to write mapping in tomcat's conf.

Re: GWT 1.4: Getting file path for FileUpload?
You cannot rely on getFilename to return full path of file. It depens on browser. For example, Firefox did not return full path of it.

Re: GWT 1.4: Getting file path for FileUpload?
There is no way to get file path from client side due to browser's security policy. You have to do it via a signed java applet or get it from your servlet.

SimpleDateFormat.format is used to convert java.util.Date object to a String
object. You used it in oposite direction by converting a String object to

Re: So I want to make a better-looking radio group...
I can't find ScrollTable widget in GWT's library. Is that your custom
widget? What is its parent class? If you use ScrollPanel as the holder of
HorizontalPanel, the dummy label cannot be added for ScrollPanel. Instead,
the width of child widget of HorizontalPanel should be given, and simply set
HorizontalPanel's alignment is enough.
Could you post some of your codes? It will be helpful to find out what's the
problem.

Re: shell fails loading
Yes. GWT's host browser used embedded tomcat server. It didn't use your installed standalone tomcat. Is your problem disappearred in normal browser, ex. IE? If normal browser has same problem, please check the Valve log. In addition, as my experience, it's not difficult to migrate to 1.5 form 1.4.62. You can get a try. Using normal browser as hosted browser is essential for development.

Re: shell fails loading
Hi Arun, If the problem only happened on GWT's hosted browser, I would suggest you to change GWT 1.53 to GWT OOPHM branches. OOPHM can let you pick firefox or IE as hosted browser. I used it for a while and satisfied by it. The current build has also merged recent 1.53 release.

Re: shell fails loading
I think it should not be the cache problem because the GWT's sample project got the same result according to Arun. He should get into HTTP server to find out what resource cannot be requested by HTTP server. HTTP 400 comes from server, I don't think the result related to GWT's shell.

Re: Dialogs BP: Do I need to remove the listeners used for widgets inside a dialog and detach the dialog?
It depends on your application purpose. If you want to keep Dialog instance for furthur use, you can keep the reference variable not to set it to null. GWT eases the developer to remember destroying widgets. When you set a widget's reference to null, GWT will free the resource automatically.

Re: Accessing a Java method from external javascript
One way you can bridge a javascript function that is inside a JSNI method to
your js function. Ex.:
In a JSNI:
public void foo_wrapper(JNITest obj)
/*-{
@com.client.JNITest::testWrapper = function(str)
{
o...@com.client.jnitest::foo(Ljava/lang/String;)(str);
};
$wnd.register_wrapper(@com.client.JNITest::testWrapper);
-}*/;
In your Test.js:
var wrapperRegistered;
function testWrapper(wrapper) {
wrapperRegistered = wrapper;
}
function callJavaMethod() {
wrapper("test");
}

Re: incubator + ProgressBar
You can simply inherit ProgressBar to overwrite method "generateText". This method is used to generated text for shown on progress bar. The progress value can be set dynamically by method "setProgress". You have to set progress bar to be invisible or remove it from parent if you don't want your user to see it after complete.

Re: OOPHM r4218: java.lang.ClassNotFoundException: com.google.gwt.user.client.rpc.RemoteService
Thanks for the reply. First, this problem did not happen in GWT 1.53. It only happens on OOPHM branch. I believe the WAR includes jar correctly. Attached is my web.xml. The lib folder I means is the subfolder of installed Tomcat directory.

OOPHM r4218: java.lang.ClassNotFoundException: com.google.gwt.user.client.rpc.RemoteService
I used NetBeans for my GWT project. Recently I tried to build OOPHM for using Firefox as my hosted browser. If I put gwt-user.jar into my WAR package, this ClassNotFoundException occurred. I tried to remove gwt-user.jar from WAR package, and put it into tomcat's lib folder. This exception doesn't happen. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
