Detailed Description

The QTranslatorMessage class contains a translator message and its properties.

This class is of no interest to most applications, just for translation tools, e.g. Qt Linguist. It is provided simply to make the API complete and regular.

For a QTranslator object, a lookup key is a triple ( context, source text, comment ) that uniquely identifies a message. An extended key is a quadruple ( hash, context, source text, comment ), where hash is computed from the source text and the comment. Unless you plan to read and write messages yourself, you need not worry about the hash value.

QTranslatorMessage stores theis triple or quadruple, the relevant translation if there is any, and the status of the message.

See also QTranslator.

QTranslatorMessage::Prefix

Let ( h, c, s, m ) be the extended key. The possible prefixes are

Member Function Documentation

QTranslatorMessage::QTranslatorMessage ()

Constructs a translator message with extended key ( 0, "", "", "" ) and QString::null as translation.

QTranslatorMessage::QTranslatorMessage ( QDataStream & stream )

Constructs a translator message read from a stream. The resulting message may have any combination of content.

See also save().

QTranslatorMessage::QTranslatorMessage ( const QTranslatorMessage & m )

Constructs a copy of translator message m.

QTranslatorMessage::QTranslatorMessage ( const char * context, const char * sourceText, const char * comment, const QString & translation = QString::null )

Constructs an translator message with extended key ( h, context, sourceText, comment ), where h is computed from sourceText and comment, and possibly with a translation.

const char * QTranslatorMessage::comment () const

Returns the comment for this message (e.g., "File > Save").

QTranslatorMessage::Prefix QTranslatorMessage::commonPrefix( const QTranslatorMessage & m ) const

Returns the widest lookup prefix that is common to this translator message and message m.

For example, if the extended key is for this message is ( 42, "FunnyDialog", "Yes", "Funny?" ) and that for m is ( 42, "FunnyDialog", "No", "Funny?" ), returns HashContext.

See also write().

const char * QTranslatorMessage::context () const

Returns the context for this message (e.g., "FunnyDialog").

uint QTranslatorMessage::hash () const

Returns the hash value used internally to represent the lookup key. This value is zero only if this translator message was constructed from a stream containing invalid data.

The hashing function is unspecified, but it will remain unchanged in future versions of Qt.

bool QTranslatorMessage::operator!= ( const QTranslatorMessage & m ) const

Returns TRUE if the extended key of this object is different from that of m, otherwise FALSE.

bool QTranslatorMessage::operator< ( const QTranslatorMessage & m ) const

Returns TRUE if the extended key of this object is lexicographically before than that of m, otherwise FALSE.

bool QTranslatorMessage::operator<= ( const QTranslatorMessage & m ) const

Returns TRUE if the extended key of this object is lexicographically before that of m or if they are equal, otherwise FALSE.

QTranslatorMessage & QTranslatorMessage::operator= ( const QTranslatorMessage & m )

Assigns m to this translator message and returns a reference to this translator message.

bool QTranslatorMessage::operator== ( const QTranslatorMessage & m ) const

Returns TRUE if the extended key of this object is equal to that of m, otherwise FALSE.

bool QTranslatorMessage::operator> ( const QTranslatorMessage & m ) const

Returns TRUE if the extended key of this object is lexicographically after that of m, otherwise FALSE.

bool QTranslatorMessage::operator>= ( const QTranslatorMessage & m ) const

Returns TRUE if the extended key of this object is lexicographically after that of m or if they are equal, otherwise FALSE.

void QTranslatorMessage::setTranslation ( const QString & translation )

Sets the translation of the source text.

See also translation().

const char * QTranslatorMessage::sourceText () const

Returns the source text of this message (e.g., "&Save").

QString QTranslatorMessage::translation () const

Returns the translation of the source text (e.g., "&Sauvegarder").

See also setTranslation().

void QTranslatorMessage::write ( QDataStream & stream, bool strip, Prefix prefix = HashContextSourceTextComment ) const

Writes this translator message to a stream. If strip is FALSE (the default), all the information in the message is written. If strip is TRUE, only the part of the extended key specified by prefix is written with the translation (HashContextSourceTextComment by default).

See also commonPrefix().
