# ABActionDelegate

Implement an Address Book action plug-in to support the display of rollover menus on top of custom items.

## Overview

Overview The ABActionDelegate informal protocol allows you to populate the rollover menus of Address Book with custom items. You do this by implementing an Address Book action plug-in. The plug-in’s Bundle must implement actionProperty(), title(for:identifier:), and performAction(for:identifier:). Each action plug-in can implement only one action. Actions can only apply to items with labels. An action can display a simple window inside the Address Book application; if your action actions needs to do anything else, it should launch your own application to perform the action. Use Xcode to create Address Book action plug-ins. Place action plug-ins in ~/Library/Address Book Plug-Ins or /Library/Address Book Plug-Ins, depending on the scope you want for the action.
