EAS BOS开发客户端端常用代码(8)

//刷新Query数据

CacheServiceFactory.getInstance().discardQuery(this.mainQueryPK);

4.26.5 设置选中根结点

treeMain.setSelectionRow(0);

4.26.6 类别新增与修改时，刷新当前选中结点

KDTreeNode treeNode = (KDTreeNode) treeMain .getLastSelectedPathComponent();

if (treeNode != null && treeNode.getParent() == null) {

TreePath oldPath = treeMain.getSelectionPath();

treeBuilder.refreshTreeNode(treeMain , treeNode,this.getDefaultFilterForTree());

treeMain.setSelectionPath(oldPath);

treeMain.expandPath(oldPath);

}

4.26.7 修改类别时刷新当前结点的父结点，并定位到当前结

点

KDTreeNode treeNode = (KDTreeNode) treeMain.getLastSelectedPathComponent(); if (treeNode != null && treeNode.getParent() != null) {

TreePath oldPath = treeMain.getSelectionPath();

TreePath parentPath = treeMain.getSelectionPath().getParentPath();

KDTreeNode parentNode = (KDTreeNode) treeNode.getParent();

treeBuilder.refreshTreeNode(treeMain , parentNode ,this.getDefaultFilterForTree());

treeMain.setSelectionPath(TreePathUtil.getNewTreePath(treeMain , treeMain.getModel() , oldPath)); }

4.27 手工发送消息

//以下是发送一个消息的核心片断，如果针对的是某组织批量发送，自己的需要取得组织的用户ID集合，然后构造receiver

SenderAgent senderAgent = SenderAgent.getSenderAgent(); Message message;

Locale[] lcla = getContextLocales(ctx);//获取ctx的语言信息列表 Locale locale = null;

message = MessageFactory.newMessage(\生成一个消息对象 for (int j = 0, m = lcla.length; j < m; j++) { //此处循环进行多语言消息的设置 locale = lcla[j]; message.setLocaleStringHeader(\标题\设置消息标题 message.setLocaleStringHeader(\发送人\设置发送人，属于文本，不是ID message.setLocaleStringHeader(\\消息体内容\设置消息体内容，根据具体业务自己设定 }

message.setIntHeader(\设置消息类型为通知

message.setIntHeader(\MsgBizType.WORKFLOW_VALUE);//业务类型设置为工作流

message.setIntHeader(\ALUE);//设置任务状态，此处是通知消息，所以设置空

message.setIntHeader(\MsgPriority.MIDDLE_VALUE);//设置消息优先级，自己根据需要设定相应的级别

message.setStringHeader(\得到数据中心 message.setStringHeader(\设置解决方案

message.setStringHeader(\

'4ff9eebb-0108-1000-e000-15acc0a813c813B7DE7F;4ff9eebb-0108-1000-e000-1db0c0a813c813B7DE7F'); //设置接收者，后面那参数是用户ID，多个ID可用分号\分割 senderAgent.sendMessage(message); //发送消息

/** * 获取ctx的语言信息列表 * * @param ctx * @return */ public static Locale[] getContextLocales(Context ctx) { Locale[] locales = null; SolutionInfo solu = MetaDataLoaderFactory.getLocalMetaDataLoader(ctx) .getSolution();

if (solu != null) { LanguageCollection langs = solu.getLanguages(); if (langs != null) {

locales = new Locale[langs.size()];

for (int i = 0; i < langs.size(); i++) { locales[i] = langs.get(i).getLocale(); } } }

return locales;

}
