visible

set [the] visible of button ¬ to trueOrFalse set [the] visible of field ¬ to trueOrFalse set [the] visible of window ¬ to trueOrFalse set [the] visible of externalWindow ¬ to trueOrFalse set [the]

 visible of menuBar ¬     to trueOrFalse

The visible property returns or sets whether a button, field, window, or the menu bar is visible on the screen.

Setting the visible of a window to true makes it the frontmost window.

With external windows, an external command or external function must first create a window before the visible will work on it. Setting the visible of a window to true (showing it) will not create the window. Similarly, setting the visible of a window to false (hiding it) doesn't remove it from the window list (from memory); use the close command to dispose of a window.

Demo Script

on flashButton
   hideShowObject "bkgnd btn id 57", 6
 end flashButton
 

 on hideShowObject whatObject, howManyTimes
   repeat for (howManyTimes * 2) times
     set the visible of whatObject to not the visible of whatObject
   end repeat
 end hideShowObject
