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
