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
