Detailed Description

An asynchronous event.

Events are produced in response to the library's need for some user intervention, such as entering a pin or password, or inserting a cryptographic token.

Event is an abstraction, so you can handle this need in a way that makes sense for your application.

Examples
eventhandlerdemo.cpp, and keyloader.cpp.

Member Enumeration Documentation

◆ Type

Type of event

See also
type()
Enumerator
Password 

Asking for a password, PIN or passphrase.

Token 

Asking for a token.

◆ Source

Source of the event

Events are associated with access to a KeyStore, or access to a file (or bytearray/stream or equivalent). This tells you the type of source that caused the Event.

See also
source()
fileName() for the name, if source is Event::Data
keyStoreInfo() and keyStoreEntry() for the keystore and entry, if the source is Event::KeyStore
Enumerator
KeyStore 

KeyStore generated the event.

Data 

File or bytearray generated the event.

◆ PasswordStyle

password variation

If the Type of Event is Password, PasswordStyle tells you whether it is a PIN, passphrase or password.

See also
passwordStyle()
Enumerator
StylePassword 

User should be prompted for a "Password".

StylePassphrase 

User should be prompted for a "Passphrase".

StylePIN 

User should be prompted for a "PIN".

Constructor & Destructor Documentation

◆ Event() [1/2]

QCA::Event::Event ( )

Constructor.

◆ Event() [2/2]

QCA::Event::Event ( const Event from)

Copy constructor.

Parameters
fromthe Event to copy from

◆ ~Event()

QCA::Event::~Event ( )

Destructor.

Member Function Documentation

◆ operator=()

Event& QCA::Event::operator= ( const Event from)

Assignment operator.

Parameters
fromthe Event to copy from

◆ isNull()

bool QCA::Event::isNull ( ) const

test if this event has been setup correctly

Examples
eventhandlerdemo.cpp.

◆ type()

Type QCA::Event::type ( ) const

the Type of this event

Examples
eventhandlerdemo.cpp, and keyloader.cpp.

◆ source()

Source QCA::Event::source ( ) const

the Source of this event

Examples
eventhandlerdemo.cpp.

◆ passwordStyle()

PasswordStyle QCA::Event::passwordStyle ( ) const

the style of password required.

This is not meaningful unless the Type is Event::Password.

See also
PasswordStyle
Examples
eventhandlerdemo.cpp.

◆ keyStoreInfo()

KeyStoreInfo QCA::Event::keyStoreInfo ( ) const

The info of the KeyStore associated with this event.

This is not meaningful unless the Source is KeyStore.

◆ keyStoreEntry()

KeyStoreEntry QCA::Event::keyStoreEntry ( ) const

The KeyStoreEntry associated with this event.

This is not meaningful unless the Source is KeyStore.

◆ fileName()

QString QCA::Event::fileName ( ) const

Name or other identifier for the file or byte array associated with this event.

This is not meaningful unless the Source is Data.

Examples
eventhandlerdemo.cpp.

◆ ptr()

void* QCA::Event::ptr ( ) const

opaque data

◆ setPasswordKeyStore()

void QCA::Event::setPasswordKeyStore ( PasswordStyle  pstyle,
const KeyStoreInfo keyStoreInfo,
const KeyStoreEntry keyStoreEntry,
void *  ptr 
)

Set the values for this Event.

This creates a Password type event, for a keystore.

Parameters
pstylethe style of information required (e.g. PIN, password or passphrase)
keyStoreInfoinfo about the keystore that the information is required for
keyStoreEntrythe entry in the keystore that the information is required for
ptropaque data

◆ setPasswordData()

void QCA::Event::setPasswordData ( PasswordStyle  pstyle,
const QString &  fileName,
void *  ptr 
)

Set the values for this Event.

This creates a Password type event, for a file.

Parameters
pstylethe style of information required (e.g. PIN, password or passphrase)
fileNamethe name of the file (or other identifier) that the information is required for
ptropaque data

◆ setToken()

void QCA::Event::setToken ( const KeyStoreInfo keyStoreInfo,
const KeyStoreEntry keyStoreEntry,
void *  ptr 
)

Set the values for this Event.

This creates a Token type event.

Parameters
keyStoreInfoinfo about the keystore that the token is required for
keyStoreEntrythe entry in the keystore that the token is required for
ptropaque data
