You are here:

invisibleValue

invisibleValue is used to make the input values invisible.

Form XML code:

<element_name invisibleValue="true">

By default, invisibleValue is set implicitly to false but is displayed as unknown in the Properties view and absent from the form XML code:

The property value will appear in the form XML code only once it is set explicitly (the Properties view will change as well):

Possible values:

true, false

Default value:

false

Associated containers, widgets and theme elements:

FunctionField

TextField

Associated 4gl syntax:

INPUT

Associated ui methods:

SetInvisibleValue ↓

GetInvisibleValue

Influence and behavior:

If invisibleValue is set to true, the input text will be hidden (replaced by ):

lycia form designer:

For the first text field (identifier=f1), invisibleValue=false:

For the second text field (identifier=f2), invisibleValue=false:

4gl code sample:

MAIN
DEFINE f1, f2 STRING
OPEN WINDOW w WITH FORM "invisibleValue" ATTRIBUTE(BORDER)
MENU
  COMMAND "input"
    INPUT BY NAME f1 WITHOUT DEFAULTS
    INPUT BY NAME f2 WITHOUT DEFAULTS
  COMMAND "exit"
    EXIT MENU
END MENU
END MAIN

runtime appearance:

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 widget_var = ui.<widget>.ForName("widget_id1")

CALL widget_var.setInvisibleValue(...)

4gl code sample:

DEFINE tf_1 ui.TextField
...
LET tf_1 = ui.TextField.ForName("f1")
CALL tf_1.setInvisibleValue(0)

DEFINE tf_2 ui.TextField
...
LET tf_2 = ui.TextField.ForName("f2")
CALL tf_2.setInvisibleValue(1)
