A button event consumed by the softbutton or clickpad code does not feed into the tap state machine, leaving it in its current state. The touch generating that event however may have triggered state changes. For some tap/click combinations this gives us either double press/release events or an inconsistent order of events. Those issues include: * a really short physical click causes a click + tap-click * a really short physical click on the right software button causes a right click + left tap-click * tap + click causes double button left press events To avoid these, notify the tap code that a button event has occured and process that accordingly. Depending on the state this may either continue to the DEAD state or release the current tap button and then go to the DEAD state.

libinput libinput is a library that handles input devices for display servers and other applications that need to directly deal with input devices. It provides device detection, device handling, input device event processing and abstraction so minimize the amount of custom input code the user of libinput need to provide the common set of functionality that users expect. Input event processing includes scaling touch coordinates, generating pointer events from touchpads, pointer acceleration, etc. libinput originates from weston, the Wayland reference compositor. The source code of libinput can be found at: http://cgit.freedesktop.org/wayland/libinput For more information, visit: http://www.freedesktop.org/wiki/Software/libinput/
