Did anybody compare the two libraries, svg.js and snap.svg.js?
Why would you prefer one over the other?

Hi,
if I understand the js fragment you posted at the beginning of this thread
var draw = SVG('drawing').size(300, 300)
means create an object SVG using as a parent element the element with the
id 'drawing'
(cause 'drawing' is a string, you can pass an element instead, i checked
the code) so
Working example:
public class SvgEntryPoint implements EntryPoint {
public class SvgWidget extends Widget {
public SvgWidget() {
setElement(Document.get().createDivElement());
// SVG library should draw inside the widget's container element
drawExample(getElement());

Hello Alain,
thank you!
I understand that there is some DOM
You basically create a GWT widget based on a div element. Once that widget
is create you call your js code. Have a look at the onAttach method in the
link I showed early on.
So you call call myClientBundle.executeJSCode() inside the onAttach method
of your widget.
Hope that helps

Hi Alain,
I understand that you fetch all the JS code with the method getJsObj() and
pass it to the method setupMap. So I believe that setupMap will embed the
JS code into the div element.
But what exactly is going on there?
(I do not know the Maps API):
private native void
If this script is central to your application, you can simply include it in
your host page. Then you can access it from your GWT code.
If this script is used only under certain conditions, you can inject it when
necessary using a ScriptInjector.
Both approaches work well.

Hi,
I have a minimal example now, see below.
I included the JS code as a ClientBundle and also called injectScript:
public class SampleLoader
{
public void injectScript()
{
String raw = SampleAssetsBundle.instance.myScript().getText();
ScriptElement e =

Hi,
I have been searching for SVG support in GWT for an long time.
Now I have found something that seems to be exactly what I am looking for:

- It's lightweight.
- It supports importing SVG files.
- The demo shows all the features I need (simple drawings, svg

But what about my question? :-)

There's two general approaches:
1) Write large JSNI methods that do all the interaction in Javascript
2) Use GWT's JavaScriptObject, subclass the library's objects, and write
small JSNI methods that wrap individual methods of the JS object.
There's supposed to be better JS interop coming in GWT
Should cover the most:
http://www.gwtproject.org/doc/latest/DevGuideCodingBasicsJSNI.html
Personally I use ClientBundle + (External)TextResource + ScriptInjector to
inject the JS code into the browser.

Thanks, it covers most of the stuff relating to embed JS within Java code...
But one important thing seems to be missing at the first sight:
How to include a whole JS library into the GWT project and access its
methods...

I have already said how to load it into the browser, so not sure what you
mean. If you mean code completion in your IDE I have no idea how well
Eclipse handles it. In IntelliJ it works pretty well.

Ok, this must be the method with ClientBundle. I missed this.
It seems that you can also simply include it in the module xml:

Hi,
including a script tag in the module xml did not work for me:
The Cross-Site-Iframe linker does not support script tags in the gwt.xml
files
Using ClientBundle works.
However, what is still missing is the connection between the JS objects and
the GWT widgets.
Consider the initial
