1、图片上载
图片的上载是在事务代码SWM0中操作的。
输入包slis进去，然后新建一个对象，尚在成功后相关的数据在数据表WWWDATA中存储，可以通过对象名称查找出来
2、创建屏幕100在屏幕上加上定制控制对象元素P1。
3.代码实现：
*&---------------------------------------------------------------------*
*& Report YTEST019
*&
*&---------------------------------------------------------------------*
*&
*&
*&---------------------------------------------------------------------*
REPORT ytest019.
DATA:ok_code TYPE sy-ucomm,
save_ok TYPE sy-ucomm.
*定义控制和图片对象定义
DATA container TYPE REF TO cl_gui_custom_container.
DATA picture TYPE REF TO cl_gui_picture.
*初始标识字段定义
DATA init.
*直接调用窗口
CALL SCREEN 100.
INCLUDE ytest019_exiti01.
*&---------------------------------------------------------------------*
*& Module USER_COMMAND_0100 INPUT
*&---------------------------------------------------------------------*

save_ok = ok_code.

*& Module STATUS_0100 OUTPUT
*&---------------------------------------------------------------------*
* text
*----------------------------------------------------------------------*
MODULE status_0100 OUTPUT.
* SET PF-STATUS 'xxxxxxxx'.
* SET TITLEBAR 'xxx'.
*如果还未创建定制对象

CREATE OBJECT container

CREATE OBJECT picture

EXCEPTIONS
