Overview

The QCPlugInViewController class communicates (through Cocoa bindings) between a custom patch and the view used for the internal settings of the custom patch. Only custom patches that use internal settings exposed to the user need to use the QCPlugInViewController class.

You access the internal settings of a custom patch through key-value coding (KVC). All the KVC keys that represent the internal settings of the custom patch must be listed in its plugInKeys method.

The view controller for a custom patch expects

• the nib file File's Owner class set to the QCPlugInViewController class

• the view outlet connected to the view that contains the editing controls

The controls are bound to the File's Owner as the target and plugIn.XXX as the model key path, where XXX is the KVC key for a given internal setting of the custom patch instance.
