Detailed Description

Media transport.

This class represents a media transport interface.

Member Enumeration Documentation

State

enum class BluezQt::MediaTransport::State

strong

Indicates the state of the transport.

Definition at line 39 of file mediatransport.h.

Property Documentation

state

State BluezQt::MediaTransport::state

read

Definition at line 34 of file mediatransport.h.

volume

quint16 BluezQt::MediaTransport::volume

read

Definition at line 35 of file mediatransport.h.

Constructor & Destructor Documentation

~MediaTransport()

BluezQt::MediaTransport::~MediaTransport ( )

overridedefault

Destroys a MediaTransport object.

Member Function Documentation

acquire

TPendingCall< QDBusUnixFileDescriptor, uint16_t, uint16_t > * BluezQt::MediaTransport::acquire ( )

slot

Acquire transport file descriptor and the MTU for read and write respectively.

Possible errors: PendingCall::NotAuthorized, PendingCall::Failed

Returns

<fd, uint16, uint16> pending call

Definition at line 43 of file mediatransport.cpp.

audioConfiguration()

AudioConfiguration BluezQt::MediaTransport::audioConfiguration

(

)

const

Returns the (audio) configuration of the transport.

Returns

configuration of transport

Definition at line 23 of file mediatransport.cpp.

release

TPendingCall< void > * BluezQt::MediaTransport::release ( )

slot

Releases file descriptor.

Returns

void pending call

Definition at line 53 of file mediatransport.cpp.

setVolume()

PendingCall * BluezQt::MediaTransport::setVolume

(

quint16

volume

)

Sets the volume of the transport.

Only works when the transport was acquired by the sender.

Parameters

quint16

volume of the transport in the range [0x00..0x7F] (0-127)

Returns

void pending call

Since

6.6

Definition at line 38 of file mediatransport.cpp.

state()

MediaTransport::State BluezQt::MediaTransport::state

(

)

const

Returns the state of the transport.

Returns

state of transport

Definition at line 28 of file mediatransport.cpp.

stateChanged

void BluezQt::MediaTransport::stateChanged ( State state )

signal

Indicates that transport's state have changed.

tryAcquire

TPendingCall< QDBusUnixFileDescriptor, uint16_t, uint16_t > * BluezQt::MediaTransport::tryAcquire ( )

slot

Acquire transport file descriptor only if the transport is in "pending" state at the time the message is received by BlueZ.

Otherwise no request will be sent to the remote device and the function will just fail with org.bluez.Error.NotAvailable.

Possible errors: PendingCall::NotAuthorized, PendingCall::Failed, PendingCall::NotAvailable

Returns

<fd, uint16, uint16> pending call

Definition at line 48 of file mediatransport.cpp.

volume()

quint16 BluezQt::MediaTransport::volume

(

)

const

Returns the volume of the transport.

The volume is a percentage of the maximum. The value 0x00 corresponds to 0%. The value 0x7F corresponds to 100%. Scaling should be applied to achieve values between these two. The existence of this scale does not impose any restriction on the granularity of the volume control scale on the target. As this command specifies a percentage rather than an absolute dB level the controller should exercise caution when sending this command.

Returns

volume of transport

Definition at line 33 of file mediatransport.cpp.

volumeChanged

void BluezQt::MediaTransport::volumeChanged ( quint16 volume )

signal

Indicates that transport's volume have changed.
