一、摘要

实现OAF的Tree功能

二、案例

需求：实现OAF的Tree功能

1. 建立两个Page，树结构页面和明细页面

2. 在树页面中建立Tree，在Tree中建立Node和 Members

(1). Node的重要属性

URI：OA.jsp?page=/bxj/oracle/apps/ak/test/webui/TreeDetailPG&employeeId={@EmployeeId}&OAPLRS=PLNH

Target Frame:　OACFr

(2). Members的重要属性

URI：/bxj/oracle/apps/ak/test/webui/TreeRootPG.TreeRN

View Link Instance: ???

View Link Accessor: DirectReport、

(3). &OAPLRS=PLNH: 代表了打开的Page无Window Title结构

3. 建立三个Function

(1). Function1：设定为Tree Page

OA.jsp?page=/bxj/oracle/apps/ak/test/webui/TreeRootPG&OAPLRS=PLNH

(2). Function2: 设定为Detail Page

OA.jsp?page=/bxj/oracle/apps/ak/test/webui/TreeDetailPG

(3). Function3: 设定为虚拟，对应Tree&Detail Page

OAFrame.jsp?OAFunc=FWK_TBX_TREE_CENTERFRAME:FWK_TBX_TREE_STARTFRAME:FWK_TBX_TREE_CENTERFRAME

&OAHP=FWK_TOOLBOX_TUTORIAL_APP

&OASF=FWK_TOOLBOX_SAMPLE_BROWSE

&OAFRDIM=30p:15p

4. 设定两个CO对应至Page，及代码

5. 进行测试

三、案例实现

1. 设定Root Tree的Node属性

2. 设定Root Tree的Members属性

3. 建立Functions

4. 设定TreeRootCO，进行Tree节点的初始化

1 public void processRequest(OAPageContext pageContext, OAWebBean webBean){
2 
3     super.processRequest(pageContext, webBean);
4 
5     OAApplicationModule am = pageContext.getApplicationModule(webBean);
6 
7     am.invokeMethod("initTreeQuery");
8 
9 }

5. 设定TreeDetailCO，进行Detail页面的初始化

 1 public void processRequest(OAPageContext pageContext, OAWebBean webBean){
 2 
 3     super.processRequest(pageContext, webBean);
 4 
 5     OAPageLayoutBean pageLayout = pageContext.getPageLayoutBean();
 6 
 7     pageLayout.prepareForRendering(pageContext);
 8 
 9     UINode tabBar = pageLayout.getTabs();
10 
11     int childCount = 0;
12 
13     if( tabBar != null ) {
14 
15         childCount = tabBar.getIndexedChildCount(pageContext.getRenderingContext());
16 
17     }
18 
19     for( int i=0; i<childCount; i++){
20 
21         LinkBean child = (LinkBean) tabBar.getIndexedChild(pageContext.getRenderingContext(), i);
22 
23         if( child != null ) {
24 
25             child.setTargetFrame("_top");
26 
27         }
28 
29     }
30 
31     OAApplicationModule am = pageContext.getApplicationModule(webBean);
32 
33     String employeeId = pageContext.getParameter("employeeId");
34 
35     Serializable[] parameters = { employeeId };
36 
37     am.invokeMethod("initDetails", parameters);
38 
39 }

四、案例测试
