enabledset [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. Examplesset 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 Scripton 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
