MAIN

DEFINE f1, f2 STRING

OPEN WINDOW w WITH FORM "isMultiSelection" ATTRIBUTE(BORDER)

INPUT BY NAME f1

DISPLAY f1 TO f2

CALL fgl_getkey()

END MAIN

runtime behavior

As the results of your selection are passed as a string, the receiving variable must accept a character string (CHAR, VARCHAR, STRING).

At runtime, you can use ui methods to find out and change the property value (so as to make the input text visible or masked):

LET var = ui.ListBx.ForName("id")

CALL var.setEnableMultiSelection(...)

DISPLAY var.getEnableMultiSelection()

4gl code sample

MAIN

DEFINE f1, f2, dspl STRING,

lbx ui.ListBox

...

LET lbx = ui.ListBox.Forname("f1")

...

COMMAND "show"

LET dspl = "enableMultiSelection=", lbx.getEnableMultiSelection()

DISPLAY dspl TO f2

COMMAND "change"

CALL lbx.setEnableMultiSelection(1)

LET dspl = "enableMultiSelection=", lbx.getEnableMultiSelection()

DISPLAY dspl TO f2

...

END MAIN
