Provided Methods§

Source

fn current_event(&self) -> Option<Event>

Returns the event that is currently being handled by the controller.

At other times, None is returned.

§Returns

the event that is currently handled by @self

Source

fn current_event_device(&self) -> Option<Device>

Returns the device of the event that is currently being handled by the controller.

At other times, None is returned.

§Returns

device of the event is currently handled by @self

Source

fn current_event_state(&self) -> ModifierType

Returns the modifier state of the event that is currently being handled by the controller.

At other times, 0 is returned.

§Returns

modifier state of the event is currently handled by @self

Source

fn current_event_time(&self) -> u32

Returns the timestamp of the event that is currently being handled by the controller.

At other times, 0 is returned.

§Returns

timestamp of the event is currently handled by @self

Source

fn name(&self) -> Option<GString>

Gets the name of @self.

§Returns

The controller name

Source

fn propagation_limit(&self) -> PropagationLimit

Gets the propagation limit of the event controller.

§Returns

the propagation limit

Source

fn propagation_phase(&self) -> PropagationPhase

Gets the propagation phase at which @self handles events.

§Returns

the propagation phase

Returns the Widget this controller relates to.

§Returns

a Widget

Source

fn reset(&self)

Resets the @self to a clean state.

Source

fn set_name(&self, name: Option<&str>)

Sets a name on the controller that can be used for debugging.

§`name`

a name for @self

Source

fn set_propagation_limit(&self, limit: PropagationLimit)

Sets the event propagation limit on the event controller.

If the limit is set to PropagationLimit::SameNative, the controller won’t handle events that are targeted at widgets on a different surface, such as popovers.
