Data:

struct gestures_set * set

A pointer to the gesture set.

gesture_e type

The gesture type.

gesture_state_e state

The current state of the gesture.

gesture_funcs_t funcs

The state and memory handling functions.

gesture_callback_f callback

The gesture handling function, triggered when a gesture changes state.

gestures_bucket_t mustallfail

List of gestures that must fail for this gesture to complete.

gestures_bucket_t faildependents

List of gestures that can only complete after this gesture fails.

TAILQ_ENTRY(gesture_base) glink

A macro that resolves to pointers into the gestures bucket.

Use the gestures_bucket_*() functions to manipulate the gestures bucket, rather than manipulating it directly.

Library:

libgestures (For the qcc command, use -l gestures to link against this library)

Description:

This structure represents information that is common to all gestures. Specific gestures include the gesture base in their representation, and also include additional members to capture gesture-specific information.

It is up to the application to define the failure dependencies between gestures and to add gestures to a gesture set.
