Customizing Acrobat Help

(instead of previous libraries such as InterfaceLib), a “carbonized” executable is produced 
which can run under Macintosh OS X (in native mode) as well as Macintosh OS 8/9.
The Acrobat 5.0 and above products are carbonized. In order for a plug-in to use ADM, it 
must also be carbonized.

:
Plug-ins which do not use ADM will still work on versions other than Mac OS X even 
if they are not carbonized.
To use ADM with Acrobat on a Macintosh, you must also use a 
plist
.

Customizing Acrobat Help
You can manipulate specific parts of the Acrobat help system using a plug-in. There is no 
equivalent functionality from Acrobat JavaScript or IAC.
Controlling the “About” Box and Splash Screen
Plug-ins can set values in the preferences file (using the 
AVAppSetPreference
 method) 
to prevent the Acrobat or Adobe Reader “About” box and/or splash screen from appearing 
before displaying the first document. These changes take effect the next time Acrobat or 
Adobe Reader is launched.
Placing Plug-in Help Files in a Standard Location
The 
Help
 directory that accompanies Acrobat or Adobe Reader provides a standardized 
location for your plug-in help files. About Acrobat Plug-Ins is a standard menu item in the 
Help menu. This menu item contains a submenu. You are encouraged to have your plug-in 
add a menu item to the submenu to bring up its own “About” box.
You cannot use Acrobat JavaScript to set values in the preferences file.
You can place a help file either in the 
Help
 directory or in a subdirectory of the 
Help
 
directory. If, for example, your plug-in is localized for Japanese, you might want to place its 
Japanese help file in a 
Help_JPN
 subdirectory. To aid in opening locale-specific help files, 
the core API provides the 
AVAppOpenHelpFileWithParams
 method. There is no 
equivalent Acrobat JavaScript functionality.
