UI基础五：简单的OP组件POPUP搜索帮助

需求：给一个配置表，需要根据配置表来弹出选择框，并将选择的数据添加到SALES ORDER的项目

BSP_WD_CMPWB

新建组件：ZHSI_JPMPG

新建视图，适用VALUE NODE 参考表ZCRMT0057.(表视图，可配置，按钮)

在节点的IF_BSP_MODEL~INIT中设置选择模式：多选：

  method IF_BSP_MODEL~INIT.

    TYPES: BEGIN OF ltype_attr_struct,

    CREATE OBJECT lv_bo_coll TYPE cl_crm_bol_bo_col.

    lv_bo_coll->add( lv_value_node ).

    set_collection( lv_bo_coll ).

  endmethod.

在组件控制器中添加参数节点：OPTION,值节点，字段参考ZCRMT0057中个别字段

在组件控制器中添加返回结果节点：ZJPPJM,值节点，字段参考ZCRMT0057

根据参数条件初始化查询结果TABLE:DO_INIT_CONTEXT

  METHOD do_init_context.

      CREATE DATA lr_line.
      CREATE OBJECT lr_valuenode

          iv_data_ref = lr_line.
      lr_valuenode->set_properties( gw_zcrmt0057 ).
      lr_col->add( lr_valuenode ).
    ENDLOOP.

    me->typed_context->zjppmj->collection_wrapper->set_collection( lr_col ).
  ENDMETHOD.

重定义GET_LOCAL_TOOLBAR_BUTTONS方法，添加选择按钮（点击将选择结果返回到程序中）

  METHOD if_bsp_wd_dyn_btn_control~get_local_toolbar_buttons.
    DATA:gw_button TYPE crmt_thtmlb_button.
    rt_result = super->if_bsp_wd_dyn_btn_control~get_local_toolbar_buttons( ).
    gw_button-id = 'CHOOSE'.
    gw_button-type = cl_thtmlb_util=>gc_done.
    gw_button-text = '選択'.
    gw_button-on_click = 'ZCHOOSE'.
    gw_button-enabled = abap_true.
    APPEND gw_button TO rt_result.
  ENDMETHOD.

重定义GET_NO_OF_VISIBLE_TOOLBAR_BTNS方法，修改显示的按钮数量

  METHOD if_bsp_wd_dyn_btn_control~get_no_of_visible_toolbar_btns.
    rv_result = super->if_bsp_wd_dyn_btn_control~get_no_of_visible_toolbar_btns( ).
    rv_result = .
  ENDMETHOD.

在Event Handler中添加前面设置的ZCHOOSE:

(将选择的结果添加到组件控制器的返回节点中)

  METHOD eh_onzchoose.
    DATA lr_context_node_tree      TYPE REF TO cl_bsp_wd_context_node_tree.
    DATA lr_node                   TYPE REF TO if_bsp_wd_tree_node.

    DATA:lr_bol TYPE REF TO if_bol_bo_col.
    DATA   lv_sel_index              TYPE int4.
    DATA :lv_row_index TYPE int4,
          lr_comp      TYPE REF TO zl_zhsi_jpm_bspwdcomponen_impl,
          lr_window    TYPE REF TO cl_bsp_wd_window.

    lr_choose = me->typed_context->zjppmj->collection_wrapper->get_iterator( ).
    lr_bol = lr_choose->get_marked( ).

    lr_comp ?= me->comp_controller.
    lr_comp->typed_context->zjppjm->collection_wrapper->clear_collection( ).
    lr_comp->typed_context->zjppjm->collection_wrapper->set_collection( lr_bol ).
    lr_window = me->view_manager->get_window_controller( ).
    lr_window->call_outbound_plug( iv_outbound_plug   = 'PRD_SELECT' ).
  ENDMETHOD.

WINDOW中添加外向跳转对象：

  METHOD op_prd_select.
    me->fire_outbound_plug( iv_outbound_plug   = 'PRD_SELECT'
                             iv_data_collection = iv_data_collection ).
  ENDMETHOD.

将组件添加InterfaceView，将组件控制器的参数节点和返回结果节点添加：

在使用的组件中添加ComponentUsage:

以上将搜索帮助的查询和返回值处理完成，现在来使用位置调用组件并处理返回结果：

在BT115IT_SLSO的中添加按钮：

  METHOD do_prepare_output.
    CALL METHOD super->do_prepare_output
