GWT 研究. 1.7 版本.

使用的是google的插件.
最新的eclipse 3.5
gwt 版本是 1.7.

花了一天时间写点demo 看看这些组件都怎么使用的..

 

1

GWT1.7版本下面是不推荐使用Listener了.而改用Handler了.

似乎这样每一个button都可以添加子节点handler了.

然后在上面编写代码.

 

2

在内部类里面要调用父类的属性的时候.要添加fianl字段.

但是这并不是说这个类不可修改.这类的属性可以修改.

 

3.要是保存临时数据.

可以通过创建数组的方式去实现.

比如 final  int[]  userNo = { 0 };

 然后在内部类里面

 

testRPCButton.addClickHandler(new ClickHandler() {
            public void onClick(ClickEvent event) {
                userNo[0] = 1;
                });
            }
        });

通过这样的方式进行赋值.

 

4,都换成handler.

然后在这里面对其他Wiget进行操作.(这些wiget必须都是final的.)

 

5,在client里面是不可以用java.util.Random()的.

 

作为替换的使用:

com.google.gwt.user.client.Random

Random.nextInt() 下面的静态方法取得.

 

6,面板是没有addHandler的方法的.

 

7.在rcp当中要做的:

1) 创建借口并(在client包下)添加@RemoteServiceRelativePath("testRPC")

testRPC是定义的url.

2)借口必须.extends RemoteService

3)创建interface TestRPCAsync 回调接口.

4)实现接口.(在servic包下.)

5)在web.xml里面添加servlet(很重要否则报错:

 

2009-9-7 8:18:18 com.google.appengine.tools.development.LocalResourceFileServlet doGet
WARNING: No file found for: /test002/testRPC

 

 <!-- Servlets -->
  <servlet>
    <servlet-name>testRPC</servlet-name>
    <servlet-class>com.demo.test.server.TestRPCImpl</servlet-class>
  </servlet>
 
  <servlet-mapping>
    <servlet-name>testRPC</servlet-name>
    <url-pattern>/test002/testRPC</url-pattern>
  </servlet-mapping>

6)gwt中声明接口.

private final TestRPCAsync testRPCAsync = GWT.create(TestRPC.class);

7)在onclick中使用.

 

testRPCButton.addClickHandler(new ClickHandler() {
            public void onClick(ClickEvent event) {
                System.out.println("here call function.");
                testRPCAsync.getString(new AsyncCallback<String>() {
                    public void onSuccess(String result) {
                        System.out.println(result);
                        Window.alert(result);
                    }
                    public void onFailure(Throwable caught) {
                       
                    }
                });
            }
        });

详细参考附件代码.
