ui.Dialog.getFieldBuffer

Returns the input buffer of the specified field.

Syntax

getFieldBuffer(
   name STRING )
  RETURNS STRING

name is the form field name, see Identifying fields in ui.Dialog methods.

Usage

The getFieldBuffer() method returns the current input buffer of the specified field. The input buffer is used by the dialog to synchronize form fields and program variables. In some situations, especially when using the buffered mode or in a CONSTRUCT, you may want to access the field input buffer.

Use of the getFieldBuffer() method is only recommended in dialogs allowing field input (INPUT, INPUT ARRAY, CONSTRUCT). The behavior is undefined when used in DISPLAY ARRAY.

The parameter is a field specification, a string containing the field qualifier, with an optional prefix ("[table.]column").

LET buff = DIALOG.getFieldBuffer("customer.cust_name")

The input buffer can be set with:

A DISPLAY TO or DISPLAY BY NAME instruction
The FGL_DIALOG_SETBUFFER() function (only for the current field)
