Register Javascript callback
Hi folks, I am trying to build a system where some non-GWT Javascript
code can register itself to be run when a certain event happens within
a GWT widget. (I don't mean a browser event, I mean a business-logic
event)
What I've come up with is a List of JavaScriptObjects that are invoked
via JSNI by the Java code. I export the add and remove methods
for this list using a JSNI method:
$wnd.addCallback = /*JSNI code to my Java function*/
This functions exactly as I expect, except that addCallback is not
available to my plain-Javascript code when the page loads, only after
the GWT widget is finished loading. So any code on my page like this:
SCRIPT TYPE=...
addCallback(myFunction);
/SCRIPT
says that addCallback is null. Even using jQuery to do:
jQuery(document).ready(function() {addCallback(myFunction);})
doesn't help.
Any ideas on how to do this?

Testing a library
Hello everybody, I have a library built with GWT that I need to test thoroughly, and preferably via automated testing. For many components of it I can use unit testing easily enough but some parts use remote HTTP requests. I'm fairly inexperienced with formal testing in general - does anyone have any advice / suggestions for formal, automated testing of what appears to be non-unit-testable code? (My only thought so far is to build a small GWT module that uses the library and exercises all the code paths that I'm interested in testing.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Composite inside tree
Hi everyone, I'm having trouble building a customized tree. I'm trying to build something that looks like the Microsoft Visual Studio installer, where you've got categories (root items on the tree) which expand into a list of items with checkboxes beside them. I've built a Composite that puts a checkbox and a label in a horizontal panel, and I pass this Composite to the TreeItem constructor. This works fine in IE but comes out very weird in other browsers. There's an extra line before the start of my horizontal panel, so it makes the tree very spaced out vertically. Additionally, only this first empty line (and even then, only a space a few pixels wide) gets coloured in when the TreeItem is selected. The actual widget that should be highlighted remains as before, with just a white background. It looks like the following: + Item 1 - Item 2 || [ ] Subitem 1 [ ] Subitem 2 Where [ ] represents a checkbox, and || represents the very thin highlighting that should in fact be covering the entirety of the following line (Subitem 1). Anyone have any ideas? Thanks! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Native JSON parsing
I've been searching around to see if anyone's brought this up already
- I haven't found anything (which surprises me) so my apologies if
this is a repeat.
Browsers are slowly starting to support native JSON - I know in
particular Firefox 3.5 (released today) supports it and I'm under the
impression (although I haven't really done my homework on this one)
that some others already support it, or are working towards it. Are
there any plans to change the GWT JSONParser to use native JSON
parsing instead of the slower and less-safe eval function? A very
simple check along the lines of
if (undefined != JSON)
{
JSON.parse(myString);
}
else
{
eval('(' + myString ' + ')');
}
ought to do it, right?

I18N with drop-in languages
Hello all, I have a fair bit of experience with GWT but am by no means an expert - I have a question about I18N. I am trying to introduce GWT UIs into a very large existing web application where there is a requirement that language packs be installable by the administrator of the web app. Using static I18N like Messages and Constants is (at least on the surface) not tenable because it requires a recompile every time a locale is added or edited, and I'm not willing to make the GWT SDK (or Java, for that matter) a server-side requirement. I suppose I could make some modifications to the bootstrap process to support hot- swapping of localized compiled JS in and out of the server. This would obviously require getting rid of the strong hashing naming stuff that gets applied to the GWT JS files, and I think this would require a significant amount of work. Going with the dynamic Dictionary method is also not ideal since the app is very large and so a lot of strings might have to be downloaded each time the page is loaded. Has anyone done hot-swappable I18N in GWT before? Any tips? Thanks, Jason --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google Web Toolkit group.
