问题 I'm using GWT (Java to JavaScript) as front-end, and RPC mechanism ( AJAX ) to make server requests ( Servlets are the keys). Everything going smooth as of now.

问题 I have a FlowPanel that I'm trying to animate back and forth like an iphone nav. (See this post for my original question on how to do this) So I have it "working" with the code shown below. I say working in quotes because I'm finding that my final position of my scroller is not precise and always changes when scrolling. The GWT.log always says the actual values I'm looking for, so for instance with the call below to scrollTo, my GWT.log says: ScrollStart: 0 scrollStop: -246 But when I

问题 Is there any way to pass parameters to the .nocache.js script file generated by GWT and evaluate them in the onModuleLoad function? Like so: <script type="text/javascript" src="application/Application.nocache.js?appId=461333815262909"></script> The host page URL should be completely separated from the GWT stuff working inside, so passing the appId parameter as a query parameter for the host page and accessing it with Window.Location.getParameter is not an option. I know that I could hide such

问题 I'm looking for a GWT common purpose paging widget. So far I have found GWT widget library and the Google Incubator widgets. Is there any other free (possibly open source) widget library implementing a paging behavior. 回答1: You found the two major ones. The Google Incubator widgets might be a good bet, because the intention is for these to eventually make it into the main library. In general the GWT widget library widgets tend to be fancier, but the GWT incubator library widgets tend to be

问题 Is there a way to get the proxy that editor is editing? The normal workflow would be: public class Class implments Editor<Proxy>{ @Path("") @UiField AntoherClass subeditor; void someMethod(){ Proxy proxy = request.create(Proxy.class); driver.save(proxy); driver.edit(proxy,request); } } Now if i got a subeditor of the same proxy public class AntoherClass implements Editor<Proxy>{ someMethod(){ // method to get the editing proxy ? } } Yes i know i can just set the proxy to the Child editor with

问题 This question already has answers here : Java 8 support in GWT (2 answers) Closed 3 years ago . I have an application which is developed using GWT 2.6 and Java 7. Now I am updating it to Java 8 with GWT 2.6. Is GWT 2.6 compatible with Java 8? Will it build/compile fine? Is GWT 2.7 compatible with Java 8? Any suggestion? 回答1: If you're only interested in using a JDK 8 to compile your application, without using Java 8 language constructs, then GWT 2.6 and 2.7 will work. Java 8 as a source

问题 Currently I am programming the Web Application based on Vaadin. I am quite happy with the learning cycle and the way how easy UI can be designed. In general pluses of Vaadin are: "Native" UI programming for Java users (component hierarchy / event listeners / drag & drop / validation). Out-of-box nice collection of components (tree / table / list / ...). The minuses are: Big and complex HTML output. That slows down the browser response time (also mentioned here and there) and leads to some

问题 I need to write a custom ValueChangeHandler and call out onValueChange(ValueChangeEvent) . However I don't understand how to write a ValueChangeEvent . Maybe I understand the entire GWT event system wrong. Can anyone help? Edit: I am asking how to create my own class that dispatches the ValueChangeEvent. I understand how to listen to it. The constructor of ValueChangeEvent is not visible and I can't create it. 回答1: If you want to fire a ValueChangeEvent you must implement the interface
