+
+ For a TQTranslator object, a lookup key is a triple (\e context, \e

+ 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.
+
+ TQTranslatorMessage stores this triple or quadruple and the relevant

+ \class TQTranslator
+
+ \brief The TQTranslator class provides internationalization support for text
+ output.
+
+ \ingroup i18n
+ \ingroup environment
+ \mainclass
+
+ An object of this class tqcontains a set of TQTranslatorMessage
+ objects, each of which specifies a translation from a source
+ language to a target language. TQTranslator provides functions to
+ look up translations, add new ones, remove them, load and save
+ them, etc.
+
+ The most common use of TQTranslator is to: load a translator file
+ created with \link linguist-manual.book TQt Linguist\endlink,
+ install it using TQApplication::installTranslator(), and use it via
+ TQObject::tr(). For example:
+
+ \code
+ int main( int argc, char ** argv )
+ {
+ TQApplication app( argc, argv );
+
+ TQTranslator translator( 0 );
+ translator.load( "french.qm", "." );
+ app.installTranslator( &translator );
+
+ MyWidget m;
+ app.setMainWidget( &m );
+ m.show();
+
+ return app.exec();
+ }
+ \endcode
+ Note that the translator must be created \e before the
+ application's main window.
+
+ Most applications will never need to do anything else with this
+ class. The other functions provided by this class are useful for
+ applications that work on translator files.
+
+ We call a translation a "messsage". For this reason, translation
+ files are sometimes referred to as "message files".
+
+ It is possible to lookup a translation using tqfindMessage() (as
+ tr() and TQApplication::translate() do) and tqcontains(), to insert a
+ new translation messsage using insert(), and to remove one using
+ remove().
+
+ Translation tools often need more information than the bare source
+ text and translation, for example, context information to help
+ the translator. But end-user programs that are using translations
+ usually only need lookup. To cater for these different needs,
+ TQTranslator can use stripped translator files that use the minimum
+ of memory and which support little more functionality than
+ tqfindMessage().
+
+ Thus, load() may not load enough information to make anything more
+ than tqfindMessage() work. save() has an argument indicating
+ whether to save just this minimum of information or to save
+ everything.
+
+ "Everything" means that for each translation item the following
+ information is kept:
+
+ \list
+ \i The \e {translated text} - the return value from tr().
+ \i The input key:
+ \list
+ \i The \e {source text} - usually the argument to tr().
+ \i The \e context - usually the class name for the tr() caller.
+ \i The \e comment - a comment that helps disambiguate different uses
+ of the same text in the same context.
+ \endlist
+ \endlist
+
+ The minimum for each item is just the information necessary for
+ tqfindMessage() to return the right text. This may include the
+ source, context and comment, but usually it is just a hash value
+ and the translated text.
+
+ For example, the "Cancel" in a dialog might have "Anuluj" when the
+ program runs in Polish (in this case the source text would be
+ "Cancel"). The context would (normally) be the dialog's class
+ name; there would normally be no comment, and the translated text
+ would be "Anuluj".
+
+ But it's not always so simple. The Spanish version of a printer
+ dialog with settings for two-sided printing and binding would
+ probably require both "Activado" and "Activada" as translations
+ for "Enabled". In this case the source text would be "Enabled" in
+ both cases, and the context would be the dialog's class name, but
+ the two items would have disambiguating comments such as
+ "two-sided printing" for one and "binding" for the other. The
+ comment enables the translator to choose the appropriate gender
+ for the Spanish version, and enables TQt to distinguish between
+ translations.
+
+ Note that when TQTranslator loads a stripped file, most functions
+ do not work. The functions that do work with stripped files are
+ explicitly documented as such.
