Member Function Documentation

button()

OperationStatus lvh::Trackpad::button

(

bool

pressed

)

Submit a physical trackpad button transition.

Parameters

pressed

Whether the primary trackpad button is pressed.

Returns

Submit operation status.

close()

OperationStatus lvh::Trackpad::close ( )

overridevirtual

Close the virtual device.

Returns

Close operation status.

Implements lvh::VirtualDevice.

device_id()

DeviceId lvh::Trackpad::device_id ( ) const

overridevirtual

Get the device identifier assigned by the runtime.

Returns

Device identifier.

Implements lvh::VirtualDevice.

device_nodes()

std::vector< DeviceNode > lvh::Trackpad::device_nodes ( ) const

overridevirtual

Get platform-visible nodes associated with the device.

Returns

Device nodes and diagnostic paths currently known to the backend.

Implements lvh::VirtualDevice.

is_open()

bool lvh::Trackpad::is_open ( ) const

overridevirtual

Check whether the device is open.

Returns

true when the device can accept operations.

Implements lvh::VirtualDevice.

last_submitted_contact()

TouchContact lvh::Trackpad::last_submitted_contact

(

)

const

Get the most recently submitted touch contact.

Returns

Last submitted touch contact.

operator=() [1/2]

Trackpad & lvh::Trackpad::operator= ( const Trackpad & )

delete

Copy assignment is disabled because the handle owns device lifetime.

Returns

noexcept

Move assign a trackpad handle.

Parameters

other

Handle to move from.

Returns

(

const TouchContact &

contact

)

Place or move a trackpad contact.

Parameters

contact

Touch contact state.

Returns

Submit operation status.

profile()

const DeviceProfile & lvh::Trackpad::profile ( ) const

overridevirtual

Get the profile used to create this device.

Returns

Device profile.

Implements lvh::VirtualDevice.

(

std::int32_t

contact_id

)

Release a trackpad contact.

Parameters

contact_id

Consumer-stable contact identifier.

Returns

Submit operation status.

submit_count()

std::size_t lvh::Trackpad::submit_count

(

)

const

Get the number of successful submit operations.
