Detailed Description

Represents a Wayland seat and abstracts the underlying capabilities.

Since

Kanzi 3.9.8

Constructor & Destructor Documentation

kanzi::wayland::WaylandSeat::WaylandSeat ( wl_seat *  nativeHandle )

explicitnoexcept

Constructor.

Parameters

nativeHandle

Native Wayland handle.

Member Function Documentation

void kanzi::wayland::WaylandSeat::updateCapabilities ( uint32_t  capabilityMask )

noexcept

Updates the capability status with the provided capability mask.

See also

updateCapability()

Parameters

capabilityMask

Capability mask provided by Wayland.

template<typename T >

bool kanzi::wayland::WaylandSeat::hasCapability ( ) const

inlinenoexcept

Checks whether the capability is supported by the current environment.

Template Parameters

T	Capability type to check.

Returns

If capability is supported, true, otherwise false.

template<typename T >

void kanzi::wayland::WaylandSeat::setCapabilityListener ( const typename T::ListenerType &  listener, void *  data  )

inlinenoexcept

Helper function to register a listener for a capability.

This class stores listener internally and reattaches it to the specified capability whenever this capability becomes available. For example, if keyboard becomes unavailable and then available again, registered listener automatically reattaches to that capability.

See also

addCapabilityListener()

Template Parameters

T	Capability type for which to register a listener.

Parameters

listener	Listener to register.
data	Data pointer to receive when the listener is called.

template<typename T >

bool kanzi::wayland::WaylandSeat::addCapabilityListener ( const typename T::ListenerType &  listener, void *  data  ) const

inlinenoexcept

Adds a listener to a capability.

Template Parameters

T	Capability type for which to add a listener.

Parameters

listener	Listener to attach.
data	Data pointer to receive when the listener is called.

Returns

On success, true, otherwise false.

Member Data Documentation

const wl_interface kanzi::wayland::WaylandSeat::s_nativeInterface

static
