OO ALV中经常会用的行单击，行双击，application tool bar上添加按钮以及按钮的相应事件，如下：
1，单击：handle_hotspot_click 事件
2，双击：handle_double_click
3，工具栏上添加自定按钮: handle_toolbar，其中，butn_type = 3. 是分隔符详细参照下面代码
4， 自定义按钮相应事件：handle_command
这些事件需要用SET HANDLER先注册，然后再在类中实现，添加自己的逻辑。
下面是个完整代码以及相关屏幕的创建过程：
1） 创建0100屏幕
屏幕PAI，PBO中流逻辑代码

MODULE STATUS_0100.
MODULE INIT_CON.
PROCESS AFTER INPUT.
MODULE USER_EXIT_0100 AT EXIT-COMMAND.

2) 在0100屏幕上画自定义控件，命名为CUS01
在屏幕点击下面红框内的按钮创建控件CUS01.
