gwt-2.4

My question is really simple and shot. but hope I can have a clear answer. We can create GWT Image in many ways. Image image = new Image ( (ImageResource)imageRes); Image image = new Image ( (ImageResource)imageRes.getSafeUri() ); Image image = new Image (); image.setUrl((ImageResource)imageRes.getSafeUri().asString() ); My question is: what are the difference among these 3 ways to create a new image using ImageResouce. Which one is best or faster for first-time loading? Thanks First, you should not use the last two. An ImageResource technically represents a region within a "sprited" image: it

I am able to create and run a simple GWT application by creating all the files myself. It works fine and I am able to see the correct display. I tried playing around the code to enhance my knowledge. What I noticed is that, once I run my app with say module rename to value " testhistory " it works fine. But after that if I change rename to 's value to say " historytokentest " the app gives errors like "Unable to find ' testhistory.gwt.xml ' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?" If I change the rename to 's value back to " testhistory

Does GWT 2.4 support this case: @Entity class MyBase {...} @Entity class MyChild1 extends MyBase {...} @Entity class MyChild2 extends MyBase {...} ... @ProxyFor(MyBase.class) class MyBaseProxy extends EntityProxy {...} @ProxyFor(MyChild1.class) class MyChild1Proxy extends MyBaseProxy {...} @ProxyFor(MyChild2.class) class MyChild2Proxy extends MyBaseProxy {...} ... @Service(ArticleBase.class) public interface MyBaseRequest extends RequestContext { Request<MyBaseProxy> getStuff(); // MyChild1 here } ... Request<MyBaseProxy> getStuffRequest = request.getStuff(); getStuffRequest.fire(new Receiver

I would like my GWT widget to be notified when its CSS animation is over. In plain HTML/Javascript this is easily done by registering an event handler like so: elem.addEventListener("webkitAnimationEnd", function(){ // do something }, false); // add more for Mozilla etc. How can I do this in GWT? This type of event is unknown to GWT's DOMImpl classes, so I keep getting an error " Trying to sink unknown event type webkitAnimationEnd ". Thanks! Rok Strniša You can always write some of the native (JavaScript) code yourself: public class CssAnimation { public static native void registerCssCallback
