Detailed Description

The TQTranslatorMessage class contains a translator message and its properties.

This class is of no interest to most applications. It is useful for translation tools such as TQt Linguist. It is provided simply to make the API complete and regular.

For a TQTranslator 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.

TQTranslatorMessage stores this triple or quadruple and the relevant translation if there is any.

See also TQTranslator, Environment Classes, and Internationalization with TQt.

TQTranslatorMessage::Prefix

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

Member Function Documentation

TQTranslatorMessage::TQTranslatorMessage ()

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

TQTranslatorMessage::TQTranslatorMessage ( const char * context, const char * sourceText, const char * comment, const TQString & translation = TQString::null )

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

TQTranslatorMessage::TQTranslatorMessage ( TQDataStream & stream )

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

See also TQTranslator::save().

TQTranslatorMessage::TQTranslatorMessage ( const TQTranslatorMessage & m )

Constructs a copy of translator message m.

const char * TQTranslatorMessage::comment () const

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

Warning: This may return 0 if the TQTranslator object is stripped (compressed).

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

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

For example, if the extended key is for this message is (71, "PrintDialog", "Yes", "Print?") and that for m is (71, "PrintDialog", "No", "Print?"), this function returns HashContext.

See also write().

const char * TQTranslatorMessage::context () const

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

Warning: This may return 0 if the TQTranslator object is stripped (compressed).

uint TQTranslatorMessage::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 TQt.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

void TQTranslatorMessage::setTranslation ( const TQString & translation )

Sets the translation of the source text to translation.

See also translation().

const char * TQTranslatorMessage::sourceText () const

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

Warning: This may return 0 if the TQTranslator object is stripped (compressed).

TQString TQTranslatorMessage::translation () const

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

See also setTranslation().

void TQTranslatorMessage::write ( TQDataStream & stream, bool strip = FALSE, Prefix prefix = HashContextSourceTextComment ) const

Writes this translator message to the 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).
