Methods

class ScrollEvent

get_deltas() → Tuple[float, float]

Extracts the scroll deltas of a scroll event.

The deltas will be zero unless the scroll direction is SMOOTH.

For the representation unit of these deltas, see get_unit.

get_direction() → ScrollDirection

Extracts the direction of a scroll event.

get_unit() → ScrollUnit

Extracts the scroll delta unit of a scroll event.

The unit will always be WHEEL if the scroll direction is not SMOOTH.

Added in version 4.8.

is_stop() → bool

Check whether a scroll event is a stop scroll event.

Scroll sequences with smooth scroll information may provide a stop scroll event once the interaction with the device finishes, e.g. by lifting a finger. This stop scroll event is the signal that a widget may trigger kinetic scrolling based on the current velocity.

Stop scroll events always have a delta of 0/0.
