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 发射 transferProgress () signal, which indicates the progress of the file transfer.

enum QBluetoothTransferReply:: TransferError

This enum describes the type of error that occurred

常量	值	描述
QBluetoothTransferReply::NoError	0	没有错误。
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.

成员函数文档编制

[protected] QBluetoothTransferReply:: QBluetoothTransferReply ( QObject * parent = nullptr)

构造新的 QBluetoothTransferReply with parent .

[虚拟] QBluetoothTransferReply:: ~QBluetoothTransferReply ()

销毁 QBluetoothTransferReply 对象。

[slot] void QBluetoothTransferReply:: abort ()

Aborts this reply.

[pure virtual] QBluetoothTransferReply::TransferError QBluetoothTransferReply:: error () const

The error code of the error that occurred.

另请参阅 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.

注意： 信号 error 在此类中被重载。通过使用函数指针句法连接到此信号，Qt 提供用于获得如此范例展示的函数指针的方便帮助程序：

connect(bluetoothTransferReply, QOverload<QBluetoothTransferReply::TransferError>::of(&QBluetoothTransferReply::error),
    [=](QBluetoothTransferReply::TransferError errorType){ /* ... */ });
					

该函数在 Qt 5.4 引入。

另请参阅 error () 和 errorString ().

[pure virtual] QString QBluetoothTransferReply:: errorString () const

String describing the error. Can be displayed to the user.

另请参阅 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

返回 QBluetoothTransferManager 用于创建此 QBluetoothTransferReply 对象。最初，它还是父级对象。

另请参阅 setManager ().

QBluetoothTransferRequest QBluetoothTransferReply:: request () const

返回 QBluetoothTransferRequest 用于创建此 QBluetoothTransferReply 对象。

另请参阅 setRequest ().

[protected] void QBluetoothTransferReply:: setManager ( QBluetoothTransferManager * manager )

Set the reply's manager to the manager .

另请参阅 manager ().

[protected] void QBluetoothTransferReply:: setRequest (const QBluetoothTransferRequest & request )

Set the reply's request to request .

另请参阅 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.
