实例:ABAP Tree Control 使用与ALV Grid对象关联
Tree Control 是最常用的Windows控件之一,在其他语言中成为"Tree View"等,ABAP的 Tree Contiol 能实现类似的功能。
本文主要介绍一下内容：
1. 实例一个简单的 Tree Control，双击取得节点的Key 和 TEXT
2. 建立有数据表接口的Tree Control 对象
3. 通过右键菜单实现 Tree Control节点的 增 删 改 功能
4. Tree Control对象与ALV Grid对象关联

（一）实例一个简单的 Tree Control，双击取得节点的Key 和 TEXT.
1. 创建一个ABAP程序
2. 在程序中添加一个屏幕100,使用屏幕制作器,建立Screen,添加屏幕对象
创建好的屏幕和对象界面如图:

（二）建立有数据表接口的Tree Control 对象
从数据表中读取结构，并按照数据关系建立Tree Control，
提一下思路，不做具体事例。。。
将需要的表结构存储到内表中，然后LOOP这张内表，循环调用宏来填充节点内表：例如
DEFINE CREATE_TREE. CLEAR IW_NODETABLE. IW_NODETABLE-NODE_KEY = &1. "节点KEY值 IW_NODETABLE-RELATKEY = &2. "相关联的节点KEY值 IW_NODETABLE-RELATSHIP = &3. "关联关系 IW_NODETABLE-HIDDEN = &4. IW_NODETABLE-DISABLED = &5. IW_NODETABLE-ISFOLDER = &6. "文件夹形式 * 图标,可以运行程序 SHOWICON 查阅 IW_NODETABLE-N_IMAGE = &7. "图标 IW_NODETABLE-EXP_IMAGE = &7. "图标 * IW_NODETABLE-EXPANDER. IW_NODETABLE-TEXT = &8. "节点文本 APPEND IW_NODETABLE TO IT_NODETABLE. END-OF-DEFINITION. LOOP AT <ITAB> INTO <WA>. "循环调用宏 CREATE_TREE ' ' ' ' ' ' ' ' ' ' . ... ENDLOOP.
这样节点情况，也会根据数据情况来动态变化。
（三）通过右键菜单实现 Tree Control节点的 增 删 改 功能
在OO的类中，添加两个方法
*&---------------------------------------------------------------------* *& Class (DEFINITION) LCL_APPLICATION *&---------------------------------------------------------------------* * Text *----------------------------------------------------------------------* CLASS LCL_APPLICATION DEFINITION. PUBLIC SECTION. METHODS: HANDLE_NODE_DOUBLE_CLICK FOR EVENT NODE_DOUBLE_CLICK OF CL_GUI_SIMPLE_TREE IMPORTING NODE_KEY, * 构成右键菜单的方法 HANDLE_NODE_CONTEXT_MENU_REQ FOR EVENT NODE_CONTEXT_MENU_REQUEST OF CL_GUI_SIMPLE_TREE IMPORTING NODE_KEY MENU, * 响应右键菜单的方法 HANDLE_NODE_CONTEXT_MENU_SEL FOR EVENT NODE_CONTEXT_MENU_SELECT OF CL_GUI_SIMPLE_TREE IMPORTING NODE_KEY FCODE. ENDCLASS. "LCL_APPLICATION
