Detailed Description

Base structure for different gestures that an application can receive.

A gesture is an event that is produced from a combination of several touch events in a particular order or within a certain time frame (e.g pinch).

To receive a particular gesture, the application has to create and connect to the appropriate GestureDetector.

Since:

2.4, DALi version 1.0.0

Note:

An instance of this class cannot be created.
