[代码]如何在选择画面中显示图片

下面通过一段代码介绍如何在选择画面中显示图片。

1, SMW0上载图片

Tcode：SMW0,选择Binary的选项

 

由于是测试，选择$TMP本地package，然后运行进入下一屏幕，

上载图片，命名为ZPIC，程序中会用来标识图片的。

2, 例子代码

REPORT ztest_pic_sel_screen.
TYPE-POOLS cndp.

    EXCEPTIONS

  IF sy-subrc = 0.
    PERFORM frm_build_htmlviewer.
    CALL METHOD go_picture->set_display_mode
      EXPORTING
        display_mode = cl_gui_picture=>display_mode_normal.
    CALL METHOD go_picture->load_picture_from_url_async
      EXPORTING
        url = g_url.
  ENDIF.
*&---------------------------------------------------------------------*

FORM frm_build_htmlviewer .

  DATA: repid LIKE sy-repid.
  repid = sy-repid.

  IF go_docking IS INITIAL.

    CREATE OBJECT go_docking
      EXPORTING
        repid                       = repid
        dynnr                       = sy-dynnr
        side                        = cl_gui_docking_container=>dock_at_top
        extension                   = 80
      EXCEPTIONS
        cntl_error                  = 1
        cntl_system_error           = 2
        create_error                = 3
        lifetime_error              = 4
        lifetime_dynpro_dynpro_link = 5
        OTHERS                      = 6.

    IF go_htmlviewer IS INITIAL .
      CREATE OBJECT go_picture
        EXPORTING
          parent = go_docking.
    ENDIF .
  ENDIF .
ENDFORM.

3, 测试运行

以上。
