如何在 openedge progress 4gl 中启用垂直滚动条创建多行文本字段？

Question

我有一个名为 user_notes 的数据库列。此列长度为 4000 个字符。此列有多行记录。现在我想以进度形式显示此列值。参考文献URLProgress display long field (frame/form)中提到的方法我都试过了但是该字段未启用滚动条。谁能建议如何为长文本项目字段启用垂直滚动条。

Answer 1

使用编辑器小部件。它进行自动换行并有一个垂直滚动条。

DEFINE VARIABLE Editor-1 AS CHARACTER 
     VIEW-AS EDITOR SCROLLBAR-VERTICAL
     SIZE 34 BY 8 NO-UNDO.

Editor-1 = "Test text".


DEFINE VARIABLE wWindow AS WIDGET-HANDLE NO-UNDO.

DEFINE FRAME fFrame
    Editor-1 AT ROW 2 COL 4 NO-LABEL
    WITH 1 DOWN NO-BOX KEEP-TAB-ORDER OVERLAY 
         SIDE-LABELS NO-UNDERLINE THREE-D 
         AT COL 1 ROW 1
         SIZE 40 BY 10.

CREATE WINDOW wWindow ASSIGN
     HEIGHT    = 10
     WIDTH     = 40
     SENSITIVE = yes
     HIDDEN    = no.

DISPLAY Editor-1 WITH FRAME fFrame IN WINDOW wWindow.
ENABLE Editor-1 WITH FRAME fFrame IN WINDOW wWindow.

VIEW wWindow.

WAIT-FOR CLOSE OF THIS-PROCEDURE.
