\class QTranslatorMessage
|
|
|
|
\brief The QTranslatorMessage class contains a translator message and its
|
|
properties.
|
|
|
|
\ingroup i18n
|
|
\ingroup environment
|
|
|
|
This class is of no interest to most applications. It is useful
|
|
for translation tools such as \link linguist-manual.book Qt
|
|
Linguist\endlink. It is provided simply to make the API complete
|
|
and regular.
|
|
|
|
For a QTranslator object, a lookup key is a triple (\e context, \e
|
|
{source text}, \e comment) that uniquely identifies a message. An
|
|
extended key is a quadruple (\e hash, \e context, \e {source
|
|
text}, \e comment), where \e 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 this triple or quadruple and the relevant
|
|
translation if there is any.
|
|
|
|
