QContentPropertiesPlugin Class Reference
[QtBaseModule]

Detailed Description

The QContentPropertiesPlugin class provides an interface for accessing properties and thumbnails embedded in content.

The QContent class uses QContentPropertiesPlugin to provide thumbnails of content.

The QContentProperties class uses QContentPropertiesPlugin to create instances of QContentPropertiesEngine for accessing properties embedded in content.

A plug-in which implements the QContentPropertiesPlugin interface should typically also implement the QContentPlugin interface to ensure content is assigned the correct type and so that any searchable properties are written to the database.
