Name
NSActionCell — Mac OS X 10.0
Synopsis
This subclass of NSCell
provides an implementation
of the target/action mechanism that is the
basis of interface messaging in Cocoa. This mechanism operates by
sending a message, often referred to as an action
message to a target object. The
majority of controls in the Application Kit rely on the functionality
of NSActionCell
to notify clients when the control
has been activated by the user.
While NSCell
implements most of the methods found
in NSActionCells
, it does so only passively.
NSActionCell
reimplements many of
NSCell
’s methods to provide an
active target/action mechanism and to manage the target and action of
a cell. In addition to managing these attributes of a cell,
NSActionCell
provides the necessary implementation
to provide feedback to mouse actions, such as highlighting certain
active areas of a control when the mouse hovers above them.
