1、如果要使用自定義的文本對象和識別碼，需要先用se75創建文本對象和識別碼。 2、在屏幕中拖個自定義控件,拖放適當的大小,激活。 3、在代碼中申明一個cl_gui_custom_container類型的變量和一個cl_gui_textedit類型的變量。 data:gv_container type REF TO cl_gui_custom_container,
???? gv_editor??? type ref to cl_gui_textedit. 4、創建上面兩個變量的實例。 if gv_container is initial.
??? CREATE OBJECT gv_container
????? EXPORTING
*??????? parent????????????????????? =
??????? container_name ?= 'GV_CONTAINER_TXT'? "一定要是屏幕中自定義控件的名字

運行下就可以看到文本編輯框了。怎么讀寫文本呢，先申明下面的變量 data:fid???? like THEAD-TDID,
???? fNAME?? like THEAD-TDNAME,
???? fobject like THEAD-TDOBJECT,
???? it_line like STANDARD TABLE OF line WITH HEADER LINE,
???? it_tline like STANDARD TABLE OF tline WITH HEADER LINE,
???? it_header like THEAD. 從數據庫中讀文本和寫文本使用read_text、create_text這兩個FM,他們有個table參數是tline類型的。 從文本編輯框中讀、寫文本使用 SPAN {font-family: "Courier New";font-size: 10pt;color: #000000;background: #FFFFFF;}</STYLE.get_text_as_r3table 和 setSPAN {font-family: "Courier New";font-size: 10pt;color: #000000;background: #FFFFFF;}</STYLE._text_as_r3table 這兩個method 他們有個table參數是line類型的。這兩種類型使用下面的form進行轉換 "
"
form. convert_tlines_to_lines.
? clear:it_line[],it_line. loop at it_tline.
??? it_line = it_tline-TDLINE.
??? append it_line.
? ENDLOOP. "clear:it_tline[],it_tline.
endform. "
"
form. convert_lines_to_tlines.
? clear:it_tline[],it_tline.
? loop at it_line.
??? it_tline-tdline = it_line.
??? append it_tline.
? ENDLOOP.
? "clear:it_line[],it_line.
endform. 把文本讀到文本編輯框中的代碼。
*&---------------------------------------------------------------------*
*&????? Form? READ_TEXT
