Quick Look Framework Reference for Mac

Introduction

Opaque Types  

This collection of documents describes the functions, types, and constants of the Quick Look framework. The Quick Look framework currently contains a public header file (QLGenerator.h) that declares the interface for generators. Quick Look generators are plug-ins that convert a document of an uncommon or private content type to a type that Quick Look can display. Upon request, they return thumbnail images or full-scale previews of documents. Generators are based on the CFPlugIn architecture. The two opaque types declared in QLGenerator.h are QLPreviewRequestRef and QLThumbnailRequestRef.

The Quick Look framework can be used to implement generator plug-ins on OS X v10.5 and later.
