Hi. I made an RPC for sending an email
this is the Impl file:

Re: Creating Stand Alone Composite??
If you create a new project with a module, dont add any entrypoint to this module.Then create all the composites you want in this module. after you may create a jar file of this project (to use anywhere) or you can just import this project into yours (click properties - java build path - projects and add your project - if you have the jar file click on libraries and add the jar.) Then just go to your gwt.xml file and add a line like: inherits name=path.to.your.gwt.xml.File/ the File is the name of the gwt.xml file. example: if the path to gwt.xml file is: com.test.toolkit.Toolkit.gwt.xml put: = com.test.toolkit.Toolkit This way, you can create many modules in the toolkit project, and group the composites by functionality.

Standard JSP + GWT Usage
Hello, My intro is a bit long but it would explain my case. Pls bear with me... Many thanks... I've started experimenting on a JSP + GWT coupling as part of a project I'm doing. This together with Struts 2.0 is a part of a project initiative that would expand the use of rich UI within a product. The idea comes in different flavors... 1. First and foremost is to use an already existing header page component with GWT components as the underlying content. 2. Have that GWT body communicate and reuse existing JSPs which are already standard within the project. 3. And of course, have JSPs communicate with the GWT body. Status of my work: I have successfully coupled the header with a GWT body. This also more or less answered the question on how I would facilitate the communication between my GWT section with the rest of the JSPs (vice- versa). I've implemented these simple experiment right on top of Struts 2.0. The makeup of the pages. To incorporate the already existing header JSP. I've renamed the GWT generated project.html to project.jsp and moved the GWT script tag component within the head tag of the header as the last element. e.g. project.jsp 1. include header 2. the rest of the elements here... Problem: When I try to proceed to another JSP right after a button is clicked from the header, say next.jsp with the following makeup... next.jsp 1. include header 2. the rest of the elements here... ... I end up seeing the following... 1. The header 2. The intended contents of next.jsp 3. The GWT content previously viewed prior to redirecting to next.jsp. Questions: 1) The first question is, why? 2) I was wondering if I would need to do an elaborate DOM element handling here to fix this. Or have I been doing anything wrong? 3) Is this coupling even feasible to implement? Any knowledge enriching feedback would be greatly appreciated.

Re: Callin an URL from my application
Hi,
I had a similar issue and this is how I was shown to do it.
public native void gotoURLscript(String url) /*-{
open(url);
}-*/;
Usage:
public void gotoURL(String url) {
gotoURLscript(URL.encode(url));
}
This will do any url on your client. If you are wishing one that only
does local mail from the client.
private static native void mailtoImpl(String address, String
subject) /*-{
$wnd.location = mailto:; + address + ?subject= + subject;
}-*/;
public static void SendMail(String emailaddress, String subject) {
mailtoImpl(emailaddress, URL.encode(subject));
}
Hope this helps.

Re: GWT architecture MVP/EventBus (mentioned at Google I/O)
For everyone following this thread, I would recommend to take a look in the presenter's implementation created by David http://gwt-presenter.googlecode.com I'm taking a look on it too, and it seems to be very interesting. I will port my little application as a proof concept. As soon as possible I will post here a feedback. Best regards, Eduardo S.

Here's question / comment... I don't understand the go() method on the presenter impl classes. Take for example mainPresenter.go(): it does a bit of widget composition adding the menu and returns the view which is the job of getView(). Then in go() you call menuPresenter.showMenu() which doesn't actually show the menu but instead it returns the view which is again the job of MenuPresenterImpl.getView(). My guess is you are (like me) having some problems in the last metre of the 100m just glueing the application together. I don't have a nice answer for that yet... Just a thought: how about building *some of* the view hierarchy via DI too and inject the very same views (widgets) in both their parent widget (for view compositing) and presenter? (only in the case of singletons of course, and use providers and/or these getView/getWidget methods we've talked about otherwise). E.g. in Eduardo's sample: inject a MenuWidget instance into both the MainWidget constructor and the MenuPresenterImpl (MenuWidget is laid out by MainWidget and controlled by MenuPresenterImpl); and in the case of the IssueDisplayXXX and IssueEditXXX, use providers as of today for lazy-init (inject ProviderIssueDisplayWidget and ProviderIssueEditWidget into MainWidget), but use singletons though, so that the view and presenter are correctly associated while still using two distinct, unrelated providers. And only in those cases where you need several instances of a component (presenter/view) you'd have to use the getView/getWidget methods so that you get/create a presenter instance from the Ginjector which gets injected its own view. It's just an idea, feel free to reject it with whichever argument comes to your mind ;-) -- Eduardo S.

Re: Hooking a GWT event onto an element in an external iframe
Hi Tin,
There is a potential for memory leaks via event listeners due to
cyclical references between DOM and JS. To avoid this, GWT manages the
event listeners via the Widget lifecycle. When the widget is attached
to the DOM (i.e. it or it's ancestor is attached to a RootPanel) the
widget's event listener is initialized. When the widget is detached
(or the page is unloaded) the event listener is cleaned up. You can
see the code in Widget.onAttach() and Widget.onDetach().
I'd say it is erroneous to use Widget outside of the normal Widget
containment hierarchy. Instead, we can set an event listener directly:
DOM.setEventListener(buttonElement, new EventListener()
{
// you will only get the events you sink
void onBrowserEvent(Event event)
{
// references in this method can result in a memory leak
Window.alert(GWT-hacky-clicked!);
}
});
// connect the foreign element to the GWT event dispatcher
DOM.sinkEvents(buttonElement, Event.ONCLICK);
Also consider adding a Window CloseHandler to prevent the memory leak.
Window.addCloseHandler(new CloseHandlerWindow() {
public void onClose(CloseEventWindow event)
{
DOM.setEventListener(buttonElement, null);
}
});
You can also look at HandlerManager and DomEvent.fireNativeEvent() to
see how to translate Event into a ClickEvent, but IMO that is
overkill.

I am writing a GWT app that involves interacting with an external
document in an iframe. As a proof of concept, I am trying to attach a
click handler to a button.
The following works in javascript
var iframe = document.getElementById(rawJSIFrame);
var doc = iframe.contentDocument;
var body = doc.body;
var button = doc.getElementsByTagName(input).namedItem(submit);
button.onclick = function() {
alert(Clicked!);
};
Trying to do the equivalent in GWT, I did the following:
public void addClickHandlerToSubmitButton(String buttonElementName,
ClickHandler clickHandler) {
IFrameElement iframe = IFrameElement.as(frame.getElement());
Document frameDocument = getIFrameDocument(iframe);
if (frameDocument != null) {
Element buttonElement = finder(frameDocument).tag(input).name
(buttonElementName).findOne();
ElementWrapper wrapper = new ElementWrapper(buttonElement);
HandlerRegistration handlerRegistration =
wrapper.addClickHandler(clickHandler);
}
}
private native Document getIFrameDocument(IFrameElement iframe)/*-{
return iframe.contentDocument;
}-*/;
The following is the ElementWrapper class:
public class ElementWrapper extends Widget implements HasClickHandlers
{
public ElementWrapper(Element theElement) {
setElement(theElement);
}
public HandlerRegistration addClickHandler(ClickHandler handler) {
return addDomHandler(handler, ClickEvent.getType());
}
}
The code to find the button works fine but the actual click event
handler is not getting invoked. Has anybody had a similar issue
before, and how did you resolve it?

[gwt-contrib] Re: Trouble building GWT 2.0 from svn
Same as Brett, that's all you need. Using ant 1.7.1 java 6u14 amd64. On Jul 19, 4:01 am, brett.wooldridge brett.wooldri...@gmail.com wrote: Not sure what the problem is.

I didn't set any environment variables (not even GWT_TOOLS), I have no classpath in my environment, etc. The only thing in my path is Ant and Java. --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---
