Struct EventController 

pub struct EventController { /* private fields */ }

EventController is a base, low-level implementation for event controllers. Those react to a series of GdkEvents, and possibly trigger actions as a consequence of those.

This is an Abstract Base Class, you cannot instantiate it.

Properties

propagation-phase

The propagation phase at which this controller will handle events.

Readable | Writeable

widget

The widget receiving the GdkEvents that the controller will handle.

Readable | Writeable | Construct Only
