关于ICON的显示和输出

1、定义字段
data: status_icon type icons-text.

2、创建屏幕，并在屏幕定义创建一个"Status Icon"控件 ,命名为:status_icon

3、利用ICON_CREATE函数在输出是设置ICON。
call function \'ICON_CREATE\'
       exporting
            name                  = \'ICON_GREEN_LIGHT\'
            text                      = \'图标后面显示的文本\'
            info                     = \'提示\'
            add_stdinf            = \'X\'
       importing
            result                = status_icon
       exceptions
            icon_not_found        = 1
            outputfield_too_short = 2
            others                = 3.

4、sap的图标可以使用ICON_SHOW函数显示列出
call function \'ICON_SHOW\' exporting onlydisplay = \'X\'
exceptions no_object_found = 1
no_icon_selected = 2.

5、关于图标的样例可参见sap的演示代码：DEMO_DYNPRO_STATUS_ICONS

REPORT demo_dynpro_status_icons.

DATA value TYPE i VALUE 1.

DATA: status_icon TYPE icons-text,
icon_name(20) TYPE c,

    WHEN 1.
      icon_name = \'ICON_GREEN_LIGHT\'.
      icon_text = text-003.
    WHEN 2.
      icon_name = \'ICON_YELLOW_LIGHT\'.
      icon_text = text-002.
    WHEN 3.
      icon_name = \'ICON_RED_LIGHT\'.
      icon_text = text-001.
ENDCASE.

CALL FUNCTION \'ICON_CREATE\'
       EXPORTING
            name                  = icon_name
            text                  = icon_text
            info                  = \'Status\'
            add_stdinf            = \'X\'
       IMPORTING
            result                = status_icon
       EXCEPTIONS
            icon_not_found        = 1
            outputfield_too_short = 2
            OTHERS                = 3.

ENDCASE.
