Arguments
| :: ByteString | Device name |
| -> DeviceOpts | |
| -> IO Device |
Create a new uinput device.
writeEvent :: Device -> EventData -> IO () Source #
Write a single event. Doesn't issue a sync event, so: writeEvent dev e /= writeBatch dev [e].
writeBatch :: Foldable t => Device -> t EventData -> IO () Source #
Write several events followed by a SynReport.
data DeviceOpts Source #

deviceOptsFromEvents :: Maybe (AbsoluteAxis -> AbsInfo) -> Maybe (RepeatEvent -> Int) -> [EventData] -> DeviceOpts Source #
Make options for a device capable of precisely the events in the list.
deviceSyspath :: Device -> IO (Maybe ByteString) Source #
deviceDevnode :: Device -> IO (Maybe ByteString) Source #

An input event, including the timestamp.
An input event, without the timestamp.
Each constructor corresponds to one event type, except for UnknownEvent.
