// ColorInspector.h
// By Kevin Brain ([e-mail])

// ColorInspector is responsible for the 'color' inspector view.

// This class is an example of a class that is responsible for
// a set of inspector views in an application.  Such classes
// act as intermediaries between the controls of inspector
// views and the currently selected object.  These classes
// have outlets to each control in the inspector views it is
// responsible for, and methods that act as the targets for
// each of these controls.  This intermediary class is
// necessary because the application can have more than one
// "inspectable views", each which may be "inspected" on a
// particular "inspector view", so we don't directly connect
// the inspector controls to the actual object that the control
// is currently affecting.  Instead, the controls are connected
// to the inspSet{*} methods of this class, and these methods
// send a corresponding message to the object itself.  They do
// this by sending the message to the 'currentParameterReceiver'.
// This means that a setCurrentParameterReceiver: message must
// be sent to this class when a new object is selected to set
// the object as the currentParameterReceiver.  (Another option
// is to have the inspSet{*} methods find out the currently
// selected object (somehow) at the time it is invoked.)
// The reflect{*}Attributes: methods reflect the attributes of an
// object on the controls of a particular inspector view.
// The {*}InspectorNum methods return the inspector number
// assigned to the inspector when it was given to InspectorManager
// in the setupInspectors: method.
// Notice how this class is set up to have only one instance in
// an application.  After the first instance of the class is
// created using the 'class method 'new', subsequent calls to
// new return a pointer to this single instance.
