NSPopover

A means to display additional content related to existing content on the screen.

Declaration

class NSPopover

Overview

The popover is positioned relative to the existing content and an anchor is used to express the relation between these two units of content. A popover has an appearance that specifies its visual characteristics, as well as a behavior that determines which user interactions will cause the popover to close. A transient popover is closed in response to most user interactions, whereas a semi-transient popover is closed when the user interacts with the window containing the popover’s positioning view. Popovers with application-defined behavior are not usually closed on the developer’s behalf.

The system automatically positions each popover relative to its positioning view and moves the popover whenever its positioning view moves. A positioning rectangle within the positioning view can be specified for additional granularity.

Popovers can be detached to become a separate window when they are dragged by implementing the appropriate delegate method.
