## 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

enum QCA::Event::Type

Type of event

See also
  type()

Enumerator
Password | Asking for a password, PIN or passphrase.
Token | Asking for a token.

## Source

enum QCA::Event::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

enum QCA::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".

## Member Function Documentation

## operator=()

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

Assignment operator.

Parameters

  from | the Event to copy from

References Event().

## 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.

  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.

Referenced by setPasswordKeyStore(), and setToken().

## keyStoreEntry()

KeyStoreEntry QCA::Event::keyStoreEntry | ( |  | ) | const

The KeyStoreEntry associated with this event.

This is not meaningful unless the Source is KeyStore.

Referenced by setPasswordKeyStore(), and setToken().

## 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.

Referenced by setPasswordData().

## ptr()

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

opaque data

Referenced by setPasswordData(), setPasswordKeyStore(), and setToken().

## 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

  pstyle | the style of information required (e.g. PIN, password or passphrase)
  keyStoreInfo | info about the keystore that the information is required for
  keyStoreEntry | the entry in the keystore that the information is required for
  ptr | opaque data

References keyStoreEntry(), keyStoreInfo(), and ptr().

## 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

  pstyle | the style of information required (e.g. PIN, password or passphrase)
  fileName | the name of the file (or other identifier) that the information is required for
  ptr | opaque data

References fileName(), and ptr().

## 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

  keyStoreInfo | info about the keystore that the token is required for
  keyStoreEntry | the entry in the keystore that the token is required for
  ptr | opaque data
