Expand description

Touch slot related functions all TouchEvents implement, that can be mapped to slots.

A touch slot is grouping all events related to a single gesture together.

Provided Methods

A seat slot is a non-negative seat wide unique identifier of an active touch point.

Events from single touch devices will be represented as one individual touch point per device.

See the kernel’s multitouch protocol B documentation for more information.

If the touch event has no assigned slot, for example if it is from a single touch device, this function returns None.
