WebDynpro ABAP 中WDALV 的 ToolBar 设置.doc

ALV FUNCTION:TOOLBAR上可以对两类TOOLBAR进行显示和设置,分别为系统标准及用户自定义的。1。系统标准（Standard Functions），默认ALV显示，可以看到“视图”，“显示为”，“打印”等可以通过接口为if_salv_wd_std_functions设置其是否显示，显示位置，布局等。2。用户自定义（Application Functions），用户可以自定义添加各种UI及事件。可以通过接口为 if_salv_wd_function_settings来实现，UI的类型，位置等。通过继承ALV的ON_FUNCTION加入处理事件。用户可生成的控件种类：Button,ToggleButton,DropDownByKey,DropDownByIndex,InputField,LinkToURL,linkToAction,ButtonChoice 用户自定义的TOOLBAR，简单实现如下：在CONTEXT中新建节点FUNCTION_ELEMENTS，与WDALV中的FUNCTION_ELEMENTS映射绑定。 FUNCTION_ELEMENT下新建CHECKED，CHOICE，INFUTFIELD，DROPYDOWNBYKEY等属性，供生成UI时使用， 以及触发操作后从此读值。DATA:R_TABLE TYPE REF TO CL_SALV_WD_CONFIG_TABLE。 METHODconfigure_alv. “ALV上TOOLBAR设置*.checkALVcomponentusageDATA:lr_salv_wd_table_usageTYPEREFTOif_wd_component_usage.lr_salv_wd_table_usage=wd_this-wd_cpuse_salv_wd_table().IFlr_salv_wd_table_usage-has_active_component()ISINITIAL.lr_salv_wd_table_usage-create_component().ENDIF.*.getALVcomponentDATA:lr_salv_wd_tableTYPEREFTOiwci_salv_wd_table.lr_salv_wd_table=wd_this-wd_cpifc_salv_wd_table().*.(1)getConfigurationModelfromALVComponentwd_this-r_table=lr_salv_wd_table-get_model().*.(2)initConfigurationModel*.initToolbarDATA:lr_functionsTYPEREFTOif_salv_wd_function_settings.lr_functions?=wd_this-r_table.DATA:lr_functionTYPEREFTOcl_salv_wd_function.DATA:lr_buttonTYPEREFTOcl_salv_wd_fe_button,lr_toggle_buttonTYPEREFTOcl_salv_wd_fe_toggle_button,lr_dropdown_by_keyTYPEREFTOcl_salv_wd_fe_dropdown_by_key,lr_dropdown_by_idxTYPEREFTOcl_salv_wd_fe_dropdown_by_idx,lr_input_fieldTYPEREFTOcl_salv_wd_fe_input_field,lr_link_to_actionTYPEREFTOcl_salv_wd_fe_link_to_action,lr_link_to_urlTYPEREFTOcl_salv_wd_fe_link_to_url,lr_button_choiceTYPEREFTOcl_salv_wd_fe_button_choice.lr_function=lr_functions-create_function(MYLEFTBUTTON).CREATEOBJECTlr_button.lr_button-set_text(MYLEFTBUTTON).lr_function-set_editor(lr_button).lr_function=lr_functions-create_function(MYTOGGLEBUTTON).CREATEOBJECTlr_toggle_buttonEXPORTINGchecked_elementname=CHECKED.lr_toggle_button-set_text(MYTOGGLEBUTTON).lr_toggle_button-set_image_source(ICON_FLIGHT).lr_toggle_button-set_checked_image_source(ICON_FLIGHT).lr_function-set_editor(lr_toggle_button).lr_function=lr_functions-create_function(MYDROPDOWNBYKEY).CREATEOBJECTlr_dropdown_by_keyEXPORTINGselected_key_elementname=DROPDOWNBYKEY.lr_dropdown_by_key-set_label_text(MYDROPDOWNBYKEY).lr_function-set_editor(lr_dropdown_by_key).lr_function=lr_functions-create_function(MYDROPDOWNBYINDEX).CREATEOBJECTlr_dropdown_by_idxEXPORTINGtexts_elementname=DROPDOWNBYINDEX.VALUE.lr_dropdown_by_idx-set_label_text(MYDROPDOWNBYINDEX).lr_function-set_editor(lr_dropdown_by_idx).lr_function=lr_functions-create_function(MYINPUTFIELD).CREATEOBJECTlr_input_fieldEXPORTINGvalue_elementname=INPUTFIELD.lr_input_field-set_label_text(MYINPUTFIELD).lr_function-set_editor(lr_input_field).lr_function=lr_functions-create_function(MYLINKTOACTION).CREATEOBJECTlr_link_to_action.lr_link_to_action-set_text(MYLINKTOACTION).lr_function-set_editor(lr_link_to_action).lr_function=lr_functions-create_function(MYLINKTOURL).CREATEOBJECTlr_link_to_url.lr_link_to_url-set_text(MYLINKTOURL).lr_link_to_url-set_reference(http:www.amazon.de).lr_function-set_editor(lr_link_to_url).lr_function=lr_functions-create_function(MYBUTTONCHOICE).CREATEOBJECTlr_button_choice.lr_button_choice-set_text(MYBUTTONCHOICE).lr_function-set_editor(lr_button_choice).lr_button_choice-set_repeat_selected_action(abap_true).*lr_button_choice-set_selected_action_item(CHOICE_3).lr_button_choice-set_sel_action_itm_elementname(CHOICE).DATA:lr_choiceTYPEREFTOcl_salv_wd_menu_action_item.CREATEOBJECTlr_choiceEXPORTINGid=CHOICE_1.lr_choice-set_text(Choice1).#ECNOTEXTlr_button_choice-add_choice(lr_choice).CREATEOBJECTlr_choiceEXPORTINGid=CHOICE_2.lr_choice-set_text(Choice2).#ECNOTEXTlr_button_choice-add_choice(lr_choice).CREATEOBJECTlr_choiceEXPORTINGid=CHOICE_3.lr_choice-set_text(Choice3).#ECNOTEXTlr_button_choice-add_choice(lr_choice).lr_function=lr_functions-create_function_right(MYRIGHTBUTTON).CREATEOBJECTlr_button.lr_button-set_text(MYRIGHTBUTTON).lr_fu
