Re: @GWTCompatible
Do I assume that nothing came from this?

Re: Limiting compilation to just for the hosted browser on windows
Values are defined in com.google.gwt.user.UserAgent.gwt.xml in gwt-user.jar. The values for GWT 1.7.x are: ie6,ie8,gecko,gecko1_8,safari,opera gecko1_8 is Firefox 1.5 and later. ie6 is IE6 and IE7. As of GWT 1.6 you can set the "user.agent" to property to multiple comma-separated values. Note that if you run the hosted shell you need to include it's value (iex on Win, safari on Mac) or "interesting" things will happen. This is a handy setting if you need to run the hosted shell on Win and occasionally compile to debug layouts in Firebug: -- Mat Gessel http://www.asquare.net On Fri, Nov 13, 2009 at 11:27 AM, Open eSignForms wrote: > Where can I see a list of user.agent values I can choose from for set- > property?

Re: GWTTestCase not running?
Which method never gets called? I would put breakpoints/asserts/System.out() in the following locations to see how far it proceeds: 1. start of test 2. start of timer run() method 3. SiteService.getPagedSongModelDataByUserId() Also, while you can use delayTestFinish() to test client/service interaction, I find it much easier to debug--and faster to run--if I test them separately. The async service is an interface which you can easily mock. The following approach allows you to run the client code synchronously. // testing client code SiteService service = new MockServiceImpl(); service.getPagedSongModelDataByUserId(...); // typically you would call a client method which then calls the service... service.getLastRequest(); // assert something w /this service.respond(...); To test the service you just use a regular TestCase and call the RPC method directly. -= Mat On Mon, Aug 31, 2009 at 7:08 PM, charlie wrote: > Hi all, I have a unit test shown here http://pastebin.com/m4e4596b1 . > > When using eclipse and Run as GWT Unit Test ( hosted mode ), the only output > I get is > > Starting HTTP on port 0 > HTTP listening on port 58504 > Compiling module com.charlie.MP3Player.JUnit > Compiling 1 permutations > Permutation compile succeeded > Linking into www-test > Link succeeded > Compilation succeeded -- 10.163s > > I have a very obvious assertFalse(true); for every condition but it looks > like it's never getting run ?

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 CloseHandler() {
public void onClose(CloseEvent 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.

Add DOM Object to an Event Handler
Hi, I am using a StringBuilder to dynamically generate a HTML Table for performance reasons (its much faster than using FlexTables). The problem is that the Table will contain input widgets and will require Event Handlers. i.e each table row will contain Input Text and on change of these each input text boxes it will update a corresponding Object. Does anyone know anyway how I can attached Dom elements that are created using the above way to Event Listeners created in GWT Java code? I dont want to have to add "" to my HTML.

Thanks for your reply.
However, I don't fully understand what you mean by "Use the same code

I have a Overlay Type and I want to iterate through all the properties

If I put my code inside a JNSI method, what is the point of having
Overlay Types?

Help: Calling a Java Function with String Array parameter from JSNI
Hi,
I am having trouble calling a static function written in Java with a
String array as the paramter:
In my Java code I have the following:
public static String[] AppendIndex(String[] names) {
String[] namesWithIndex = new String[names.length];
for(int i = 0; i < names.length; i++) {
namesWithIndex[i] = Integer.toString(i) + ". " + names[i];
}
return namesWithIndex;
}
I have exported this static function so its accessible via JSNI using
the following code.
public static native void exportStaticMethod() /*-{
$wnd.AppendIndex= @Utilities::AppendIndex([Ljava/lang/String;);
}-*/;
In my Javascript I have:
var names = ["Fat","Cat","Bat"];
var namesWithIndex = AppendIndex(names);
However, I get the following error:
