SHOW/HIDE OPTION instruction
Syntax:
{ HIDE | SHOW } OPTION
{ ALL
| option-name [,...]
}
Usage
The SHOW
OPTION
instruction will show/enable action views
corresponding the listed menu options. The default action
views (buttons in action frame) are made visible and
the explicit action views (buttons in form) are enabled.
The HIDE OPTION
instruction will hide default
action views and disable explicit action views.
Use the ALL
keyword reference all menu
options. In a menu that contains many options, you
typically do a HIDE OPTIONS ALL
followed
by HIDE OPTION
to show a subset of the menu
options.
The SHOW OPTION
and HIDE
OPTION
instructions are provided for backward
compatibility. To hide and show default action views, use the
DIALOG.setActionHidden()
method instead.
In GUI applications, it is recommended that you rather disable actions,
instead of hiding them to the end user.
