1、gxt用boeder布局時，看不見界面時，可能是要用子控件要用fitlayout布局。
?
2、grid列自動縮放：????????????
????grid.setStripeRows?(true);?grid.setAutoExpandColumn?("info");?
????grid.setAutoExpandMin?(80);?
????grid.getView?().setForceFit?(true);??
3、對于tab頁面，要想grid列寬度自適應的話還要加一下條件：
????messagePanel.setLayoutData?(new?FitLayout());?
????loggerTab?=?new?TabItem?("系統日志");
????loggerTab.setLayoutData?(new?FitLayout());?
????loggerTab.setLayoutOnChange?(true);?
????loggerTab.add?(getLoggerPanel?());?
????messagePanel.add?(loggerTab);?
?????????而且不能設置為自動寬度。
?
4、布局不起作用，可能是setLayout寫成了setLayoutData；
?
5、gxt里面盡量用boederlayout布局，那樣自適應較強；
?
6、所有遠程對象繼承下面類，可以和spring集成；
?1public?abstract?class?BaseAction?extends?RemoteServiceServlet?implements
?2
????????Controller,?ServletContextAware,?ServletConfigAware,?BeanNameAware?
{
?3
????private?ServletContext?servletContext;
?4????private?String?controllerName;
?5
?6
????/**?*//**?*?Gets?ServletContext.?*/
?7????@Override
?8????public?ServletContext?getServletContext()?{
?9????????return?servletContext;
10
????}
11
12????/**//*?
13?????*?*?(non-Javadoc)?*?*?@see?*
14?????*?org.springframework.beans.factory.BeanNameAware#setBeanName?(java.lang?*
15?????*?.String)
16?????*/
17????@Override
18????public?void?setBeanName(String?controllerName)?{
19????????this.controllerName?=?controllerName;
20????}
21
22????/**?*//**?*?Implementation?of?ServletContextAware.?*/
23????public?void?setServletContext(ServletContext?servletContext)?{
24????????this.servletContext?=?servletContext;
25????}
26
27????public?String?getServletName()?{
28????????return?"DispatcherServlet?name?is?"
29????????????????+?this.servletConfig.getServletName()
30????????????????+?",?GwtController?name?is:"?+?controllerName;
31????}
32
33????private?ServletConfig?servletConfig;
34
35????@Override
36????public?void?setServletConfig(ServletConfig?servletConfig)?{
37????????this.servletConfig?=?servletConfig;
38????}
39
40????/**?*//**
41?????*?*?Handles?request?and?delegates?to?GWT's?*
42?????*?RemoteServiceServlet.doPost(request,?response).
43?????*?*/
44????public?ModelAndView?handleRequest(HttpServletRequest?request,
45????????????HttpServletResponse?response)?throws?Exception?{
46????????try?{
47????????????doPost(request,?response);
48????????????return?null;
49????????}?catch?(Exception?e)?{
50????????????return?null;
51????????}
52????}

} 7、servlet里面推數據至gxt前臺：
后臺：
????
1RemoteEventServiceServlet?ress?=?new?RemoteEventServiceServlet?()?{?};?
2UploadEvent?event?=?new?UploadEvent?(source);
3?ress.addEvent?(UploadEvent.FILEREADING_SERVER_DOMAIN_MESSAGE,?event);?
4 ?RemoteEventServiceServlet ress = new RemoteEventServiceServlet () { }; UploadEvent event = new UploadEvent (source); ress.addEvent (UploadEvent.FILEREADING_SERVER_DOMAIN_MESSAGE, event);
前臺：
?// 啟動監聽器
?1RemoteEventService?theRemoteEventService?=?RemoteEventServiceFactory.getInstance?().getRemoteEventService?();?
?2????theRemoteEventService.addListener?(UploadEvent.UPLOAD_SERVER_DOMAIN_INBOUND,?
?3????????????new?RemoteEventListener?()?
?4????{?
?5????????public?void?apply?(de.novanic.eventservice.client.event.Event?anEvent)
?6????????{?
?7????????????if?(anEvent?instanceof?UploadEvent)?
?8????????????{?
?9????????????????UploadEvent?te?=?(UploadEvent)?anEvent;?
10????????????????sourceTemplate?=?te.getSource?();
11????????????????fileText.setValue?(te.getResultMessage?());
12????????????????}?
13????????????}?
14????});?
