详细描述
The QBluetoothTransferReply class stores the response for a data transfer request.
In additional to a copy of the QBluetoothTransferRequest object used to create the request, QBluetoothTransferReply contains the contents of the reply itself.
After the file transfer has started, QBluetoothTransferReply emits the transferProgress() signal, which indicates the progress of the file transfer.
成员类型
enum QBluetoothTransferReply::TransferError
This enum describes the type of error that occurred
| Constant | Value | Description |
|---|---|---|
QBluetoothTransferReply::NoError | 0 | No error. |
QBluetoothTransferReply::UnknownError | 1 | Unknown error, no better enum available. |
QBluetoothTransferReply::FileNotFoundError | 2 | Unable to open the file specified. |
QBluetoothTransferReply::HostNotFoundError | 3 | Unable to connect to the target host. |
QBluetoothTransferReply::UserCanceledTransferError | 4 | User terminated the transfer. |
QBluetoothTransferReply::IODeviceNotReadableError | 5 | File was not open before initiating the sending command. |
QBluetoothTransferReply::ResourceBusyError | 6 | Unable to access the resource.. |
QBluetoothTransferReply::SessionError | 7 | An error occurred during the handling of the session. This enum was introduced by Qt 5.4. |
成员函数
[protected] QBluetoothTransferReply::QBluetoothTransferReply(QObject *parent = Q_NULLPTR)
Constructs a new QBluetoothTransferReply with parent.
QBluetoothTransferReply::~QBluetoothTransferReply()
Destroys the QBluetoothTransferReply object.
[slot] void QBluetoothTransferReply::abort()
Aborts this reply.
[pure virtual] TransferError QBluetoothTransferReply::error() const
The error code of the error that occurred.
参见 errorString().
[signal] void QBluetoothTransferReply::error(QBluetoothTransferReply::TransferError errorType)
This signal is emitted whenever an error has occurred. The errorType parameter indicates the type of error.
To avoid the loss of signal emissions it is recommend to immidiately connect to this signal once a QBluetoothTransferReply instance has been created.
Note: Signal error is overloaded in this class. To connect to this one using the function pointer syntax, you must specify the signal type in a static cast, as shown in this example:
connect(bluetoothTransferReply, static_cast<void(QBluetoothTransferReply::*)(QBluetoothTransferReply::TransferError)>(&QBluetoothTransferReply::error), [=](QBluetoothTransferReply::TransferError errorType){ /* ... */ });
This function was introduced in Qt 5.4.
参见 error() and errorString().
[pure virtual] QString QBluetoothTransferReply::errorString() const
String describing the error. Can be displayed to the user.
参见 error().
[signal] void QBluetoothTransferReply::finished(QBluetoothTransferReply *reply)
This signal is emitted when the transfer is complete for reply.
To avoid the loss of signal emissions it is recommend to immidiately connect to this signal once a QBluetoothTransferReply instance has been created.
[pure virtual] bool QBluetoothTransferReply::isFinished() const
Returns true if this reply has finished, otherwise false.
[pure virtual] bool QBluetoothTransferReply::isRunning() const
Returns true if this reply is running, otherwise false.
QBluetoothTransferManager *QBluetoothTransferReply::manager() const
Returns the QBluetoothTransferManager that was used to create this QBluetoothTransferReply object. Initially, it is also the parent object.
参见 setManager().
QBluetoothTransferRequest QBluetoothTransferReply::request() const
Returns the QBluetoothTransferRequest that was used to create this QBluetoothTransferReply object.
参见 setRequest().
[protected] void QBluetoothTransferReply::setManager(QBluetoothTransferManager *manager)
Set the reply's manager to the manager.
参见 manager().
[protected] void QBluetoothTransferReply::setRequest(const QBluetoothTransferRequest &request)
Set the reply's request to request.
参见 request().
[signal] void QBluetoothTransferReply::transferProgress(qint64 bytesTransferred, qint64 bytesTotal)
This signal is emitted whenever data is transferred. The bytesTransferred parameter contains the total number of bytes transferred so far out of bytesTotal.
To avoid the loss of signal emissions it is recommend to immidiately connect to this signal once a QBluetoothTransferReply instance has been created.
