enabled

 set [the] enabled of{menu|menuItem }¬
    to trueOrFalse

set [the]

enabled of button ¬     to trueOrFalse

The enabled property returns or sets whether a menu item, menu, or button is active or inactive (dimmed). Users cannot choose dimmed elements.

If you set the enabled of a menu to false, all items on the menu become inactive.

The enabled property won't enable items in HyperCard’s menus unless they're currently available to the user.

For example, the following code won't enable the Button Info command unless a button is selected:

set the enabled of menuItem 1 of ¬ menu "Objects" to true

The default state is true, meaning that the element is enabled.

Examples

set the enabled of menu "File" to true
set the enabled of menu 2 to false
set the enabled of second menu to true

set the enabled of menuItem "New" of menu "File" to false
set the enabled of menuItem 2 of menu 2 to true
set the enabled of second menuItem of second menu to false

set the enabled of button 5 to false
if the enabled of bg btn "Scores" is true then show field "Players"

Demo Script

on mouseUp
   if there is a menu "Reference"
   then set enabled of menuItem 4 of menu "Reference" to ¬
        not (enabled of menuItem 4 of menu "Reference")
 end mouseUp
