Setting the Active Object
26
N
OTE
:
The parent object is the object that contains the specified object. For example, the application is the
parent of the document; a document is the parent of a layer, selection, or channel.
For example, if you look at the
Application
object in the
Adobe Photoshop CS4 JavaScript Scripting
Reference
, or in the ExtendScript Object Model Viewer, you find one of its properties is
activeDocument
; if
you look at the
Document
object, you will find
activeLayer
and
activeHistoryState
as properties.
Similarly, if you look at
application
in the
Adobe Photoshop CS4 AppleScript Scripting Reference
, or in the
Photoshop AppleScript Dictionary, you find it has the property of
current
, and so on.
For sample scripts that set active objects, see the following sections.

--make docRef the active document
set current document to docRef

--use the current document property of the application class to
--bring otherDocRef front-most as the new active document
