Expand description

Required methods

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

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

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

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

Gets the name of @self.

Gets the propagation limit of the event controller.

Returns

the propagation limit

Gets the propagation phase at which @self handles events.

Returns

the propagation phase

Returns the Widget this controller relates to.

Returns

a Widget

Resets the @self to a clean state.

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

name

a name for @self

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.

limit

the propagation limit

Sets the propagation phase at which a controller handles events.

If @phase is PropagationPhase::None, no automatic event handling will be performed, but other additional gesture maintenance will.

phase

a propagation phase
