## Member Type Documentation

### enum QNdefNfcSmartPosterRecord::Action

This enum describes the course of action that a device should take with the content.

Constant | Value | Description
--- | --- | ---
`QNdefNfcSmartPosterRecord::UnspecifiedAction` | `-1` | The action is not defined.
`QNdefNfcSmartPosterRecord::DoAction` | `0` | Do the action (send the SMS, launch the browser, make the telephone call).
`QNdefNfcSmartPosterRecord::SaveAction` | `1` | Save for later (store the SMS in INBOX, put the URI in a bookmark, save the telephone number in contacts).
`QNdefNfcSmartPosterRecord::EditAction` | `2` | Open for editing (open an SMS in the SMS editor, open the URI in a URI editor, open the telephone number for editing).

## Member Function Documentation

### QNdefNfcSmartPosterRecord::QNdefNfcSmartPosterRecord()

Constructs a new empty smart poster.

### QNdefNfcSmartPosterRecord::QNdefNfcSmartPosterRecord(const QNdefRecord &other)

Constructs a new smart poster that is a copy of other.

### QNdefNfcSmartPosterRecord::QNdefNfcSmartPosterRecord(const QNdefNfcSmartPosterRecord &other)

Constructs a new smart poster that is a copy of other.

### `[noexcept]` QNdefNfcSmartPosterRecord::~QNdefNfcSmartPosterRecord()

Destroys the smart poster.

### QNdefNfcSmartPosterRecord::Action QNdefNfcSmartPosterRecord::action() const

Returns the action from the action record if available. Otherwise UnspecifiedAction is returned.

See also setAction().

### void QNdefNfcSmartPosterRecord::addIcon(const QNdefNfcIconRecord &icon)

Adds an icon record icon to the smart poster. If the smart poster already contains an icon record with the same type then the existing icon record is replaced.

### void QNdefNfcSmartPosterRecord::addIcon(const QByteArray &type, const QByteArray &data)

Adds an icon record with type type and data data to the smart poster. If the smart poster already contains an icon record with the same type then the existing icon record is replaced.

### bool QNdefNfcSmartPosterRecord::addTitle(const QNdefNfcTextRecord &text)

Attempts to add a title record text to the smart poster. If the smart poster does not already contain a title record with the same locale as title record text, then the title record is added and the function returns `true`. Otherwise `false` is returned.

### bool QNdefNfcSmartPosterRecord::addTitle(const QString &text, const QString &locale, QNdefNfcTextRecord::Encoding encoding)

Attempts to add a new title record with title text, locale locale and encoding encoding. If the smart poster does not already contain a title record with locale locale, then the title record is added and the function returns `true`. Otherwise `false` is returned.

### bool QNdefNfcSmartPosterRecord::hasAction() const

Returns `true` if the smart poster contains an action record, otherwise returns `false`.

### bool QNdefNfcSmartPosterRecord::hasIcon(const QByteArray &mimetype = QByteArray()) const

Returns `true` if the smart poster contains an icon record using the type mimetype. If mimetype is empty, then `true` is returned if the smart poster contains at least one icon record. In all other cases, `false` is returned.

### bool QNdefNfcSmartPosterRecord::hasSize() const

Returns `true` if the smart poster contains a size record, otherwise returns `false`.

### bool QNdefNfcSmartPosterRecord::hasTitle(const QString &locale = QString()) const

Returns `true` if the smart poster contains a title record using the locale locale. If locale is empty, then `true` is returned if the smart poster contains at least one title record. In all other cases, `false` is returned.

### bool QNdefNfcSmartPosterRecord::hasTypeInfo() const

Returns `true` if the smart poster contains a type record, otherwise returns `false`.

### QByteArray QNdefNfcSmartPosterRecord::icon(const QByteArray &mimetype = QByteArray()) const

Returns the associated icon record data if the smart poster contains an icon record with MIME type mimetype. If mimetype is omitted or empty then the first icon's record data is returned. In all other cases, an empty array is returned.

### qsizetype QNdefNfcSmartPosterRecord::iconCount() const

Returns the number of icon records contained inside the smart poster.

### QNdefNfcIconRecord QNdefNfcSmartPosterRecord::iconRecord(qsizetype index) const

Returns the icon record corresponding to the index index inside the smart poster, where index is a value between 0 and iconCount() - 1. Values outside of this range return an empty record.

### QList<QNdefNfcIconRecord> QNdefNfcSmartPosterRecord::iconRecords() const

Returns a copy of all icon records inside the smart poster.

### bool QNdefNfcSmartPosterRecord::removeIcon(const QByteArray &type)

Attempts to remove the icon record with the type type from the smart poster. Removes the record and returns `true` if the smart poster contains a matching record, otherwise `false` is returned.

### bool QNdefNfcSmartPosterRecord::removeIcon(const QNdefNfcIconRecord &icon)

Attempts to remove the icon record icon from the smart poster. Removes the record and returns `true` if the smart poster contains a matching record, otherwise `false` is returned.

### bool QNdefNfcSmartPosterRecord::removeTitle(const QNdefNfcTextRecord &text)

Attempts to remove the title record text from the smart poster. Removes the record and returns `true` if the smart poster contains a matching record, otherwise `false` is returned.

### bool QNdefNfcSmartPosterRecord::removeTitle(const QString &locale)

Attempts to remove a title record with the locale locale from the smart poster. Removes the record and returns `true` if the smart poster contains a matching record, otherwise `false` is returned.

### void QNdefNfcSmartPosterRecord::setAction(QNdefNfcSmartPosterRecord::Action act)

Sets the action record to act

See also action().

### void QNdefNfcSmartPosterRecord::setIcons(const QList<QNdefNfcIconRecord> &icons)

See also hasIcon() and icon().

### void QNdefNfcSmartPosterRecord::setSize(quint32 size)

Sets the record size. The value contains the size in bytes of the object that the URI refers to.

See also size() and hasSize().

### void QNdefNfcSmartPosterRecord::setTitles(const QList<QNdefNfcTextRecord> &titles)

Adds the title record list titles to the smart poster. Any existing records are overwritten.

### void QNdefNfcSmartPosterRecord::setTypeInfo(const QString &type)

### quint32 QNdefNfcSmartPosterRecord::size() const

Returns the size from the size record if available; otherwise returns 0.

The value is optional and contains the size in bytes of the object that the URI refers to. It may be used by the device to determine whether it can accommodate the object.

See also setSize().

### QString QNdefNfcSmartPosterRecord::title(const QString &locale = QString()) const
