问题 Is there a way in GWT to tell if the Shift key is down inside of an onClick() handler? For example: import com.google.gwt.event.dom.client.ClickEvent; import com.google.gwt.event.dom.client.ClickHandler; public class PanelTileBase implements ClickHandler { PanelTileBase() { addClickHandler(this); } public void onClick(ClickEvent event) { // is the shift key down? } } Thanks! 回答1: How about this (untested) void onClick(ClickEvent ev) { NativeEvent nEv = ev.getNativeEvent(); if ( nEv

问题 I am using a TabBar and I want to style the component in different ways. So one time this style, another time that style. I thought this will work but it didn't: TabBar t = new TabBar(); t.addTab( "1" ); t.addTab( "2" ); t.addStyleName( MyResources.INSTANCE.css().slickTab() ); And: public interface MyResources extends ClientBundle { public static final MyResources INSTANCE = GWT.create(MyResources.class); @Source("style.css") MyCssResource css(); } public interface MyCssResource extends

问题 Is it possible to develop an application in groovy using GWT components? Luis 回答1: If you want to use Groovy on the server-side and GWT for the UI, that is certainly possible. You can use Grails (a Groovy web framework on the server), and the Grails GWT plugin to help you integrate GWT with this framework. 回答2: I don't think so, because the GWT compiler is basically a Java to JavaScript source compiler (it would be possible if the GWT compiler needed Java bytecode). You can use Groovy on the

问题 I m trying to create a GWT app- it has a single HTML file (main.html) and the java class is main.java. In Eclipse, I did right click-> GWT -> Module and defined the new module correctly. However after adding some code, when I try to run the app in Dev mode, I get the error "Could Not find any host pages in project <project-name> " I have simply added some code to main.java, then saved it and tried to run the app in dev mode... What am I doing wrong here? Is there something I am missing here?

问题 How do I convert String to Date or Date to String using GWT 2.0.3? 回答1: With the methods on the java.util.Date class itself: parse(String s) and toString() . Although the first is deprecated it is the method to use with GWT. If you want more control over how the Date is formatted, when converting to String use the GWT specific class: com.google.gwt.i18n.client.DateTimeFormat . It will format the date given a pattern, similar to Java's own SimpleDateFormat . 回答2: import com.google.gwt.i18n

问题 I'm wondering if is the way to deserialize the server response. So in my case I have an LinkedHashMap<String,Date> and returing this from server: @Override public LinkedHashMap<String, Date> testHMap() { LinkedHashMap<String, Date> map = new LinkedHashMap<>(); map.put("AA", new Date()); map.put("BB", new Date()); return map; } I'm trying to get info about another application(gwt) so I can perform calls only via HTTP, and from upper example the HTTP response looks like : //OK['WM577vZ',4,5,2,

问题 I compiled the version in svn tagged as gwt2.4rc. Now there are a couple of more libraries than I had the last time. Are the any instructions on which library is needed for what? I tried it with only the standard libraries (servlet, servlet-deps, user) but I get the following error when a requestfactory call is made: java.lang.NoSuchMethodError: com.google.gwt.core.client.impl.WeakMapping.setWeak(Ljava/lang/ Object;Ljava/lang/String;Ljava/lang/Object;) I tried declaring the requestfactory
