## Detailed Description

These classes handle input events.

Event controllers are standalone objects that can perform specific actions upon received GdkEvents. These are tied to a Widget, and can be told of the event propagation phase at which they will manage the events.

Gestures are a set of specific controllers that are prepared to handle pointer and/or touch events. Each gestures implementation attempts to recognize specific actions out the received events, notifying of the state/progress accordingly to let the widget react to those. On multi-touch gestures, every interacting touch sequence will be tracked independently.

See The GTK+ Input Handling Model for more information about input events and gestures.
