|
||
|
|
|
||
|
|
|
||
|
|
<p> The QTranslatorMessage class contains a translator message and its
|
||
|
|
properties.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> This class is of no interest to most applications. It is useful
|
||
|
|
for translation tools such as <a href="linguist-manual.html">Qt
|
||
|
|
Linguist</a>. It is provided simply to make the API complete
|
||
|
|
and regular.
|
||
|
|
<p> For a <a href="qtranslator.html">QTranslator</a> object, a lookup key is a triple (<em>context</em>, <em>source text</em>, <em>comment</em>) that uniquely identifies a message. An
|
||
|
|
extended key is a quadruple (<em>hash</em>, <em>context</em>, <em>source text</em>, <em>comment</em>), where <em>hash</em> 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.
|
||
|
|
<p> QTranslatorMessage stores this triple or quadruple and the relevant
|
||
|
|
translation if there is any.
|
||
|
|
<p> <p>See also <a href="qtranslator.html">QTranslator</a>, <a href="environment.html">Environment Classes</a>, and <a href="i18n.html">Internationalization with Qt</a>.

|

|
|
|

|
|
<p> Let (<em>h</em>, <em>c</em>, <em>s</em>, <em>m</em>) be the extended key. The possible

|
|
prefixes are
|
||
|
|
<ul>
|

|
|
<li><tt>QTranslatorMessage::NoPrefix</tt> - no prefix

|
|
<li><tt>QTranslatorMessage::Hash</tt> - only (<em>h</em>)

<li><tt>QTranslatorMessage::HashContext</tt> - only (<em>h</em>, <em>c</em>)
|

|
|
<li><tt>QTranslatorMessage::HashContextSourceText</tt> - only (<em>h</em>, <em>c</em>, <em>s</em>)
|

|

<li><tt>QTranslatorMessage::HashContextSourceTextComment</tt> - the whole extended key, (<em>h</em>, <em>c</em>, <em>s</em>, <em>m</em>)

<h3 class=fn><a name="QTranslatorMessage"></a>QTranslatorMessage::QTranslatorMessage ()
|
||
|
|
</h3>
|
||
|
|
Constructs a translator message with the extended key (0, 0, 0, 0)
|
||
|
|
and <a href="qstring.html#QString-null">QString::null</a> as translation.
|
||
|
|
|

|
||
|
|
</h3>
|
||
|
|
Constructs an translator message with the extended key (<em>h</em>, <em>context</em>, <em>sourceText</em>, <em>comment</em>), where <em>h</em> is computed from
|
||
|
|
<em>sourceText</em> and <em>comment</em>, and possibly with a <em>translation</em>.
|
||
|
|
|
||
|
|
<h3 class=fn><a name="QTranslatorMessage-3"></a>QTranslatorMessage::QTranslatorMessage ( <a href="qdatastream.html">QDataStream</a> & stream )

</h3>
|
||
|
|
Constructs a translator message read from the <em>stream</em>. The
|
||
|
|
resulting message may have any combination of content.
|
||
|
|
<p> <p>See also <a href="qtranslator.html#save">QTranslator::save</a>().

||
|
|
Returns the widest lookup prefix that is common to this translator

"PrintDialog", "No", "Print?"), this function returns <a href="#Prefix-enum">HashContext</a>.

key. This value is zero only if this translator message was
