progress-4gl - 从浏览和创建临时表中获取值

Question

我有一个动态浏览器。它将根据通过 UI 给出的一些输入动态填充值。

现在我想获取该浏览中显示的值并为此制作一个临时表。请帮忙

要添加新值，您首先将新行插入临时表，然后安排更新该行。以下代码很难看，但它可以用来说明：

define temp-table tt_simple no-undo
  field id   as integer
  field name as character
  index id_idx is unique id
.

define variable r as integer no-undo.

define query q for tt_simple.

define browse b query q display tt_simple.name with 5 down.

form b with frame easy.

form
  tt_simple.name
 with
  frame updEasy
  column 30
  row 1
.

procedure newRecord:
  define input parameter initName as character no-undo.
  create tt_simple.
  assign
    r    = r + 1
    id   = r
    name = initName
  .
end.

run newRecord( "abc" ).
run newRecord( "xyz" ).

on "enter" of b in frame easy do:
  apply "entry" to tt_simple.name in frame updEasy.
  return no-apply.
end.

on "insert-mode", "CTRL-I" anywhere do:
  run newRecord( "" ).
  close query q.
  open query q for each tt_simple.
  get last q.
  apply "entry" to tt_simple.name in frame updEasy.
  return no-apply.
end.

on "go" of tt_simple.name in frame updEasy do:
  tt_simple.name = self:screen-value.
  close query q.   
  open query q for each tt_simple.
  apply "entry" to b in frame easy.
  return no-apply.
end.

on "value-changed" of b in frame easy do:
  display tt_simple.name with frame updEasy.
end.

open query q for each tt_simple.

enable tt_simple.name with frame updEasy.
enable b with frame easy.
apply "entry" to b in frame easy.

wait-for "close" of this-procedure.
