|
|---|
| 63 |
|
|---|
| 64 |
|
|---|
| 65 | <p> The QTranslatorMessage class contains a translator message and its
|
|---|
| 66 | properties.
|
|---|
| 67 | <p>
|
|---|
| 68 |
|
|---|
| 69 | <p> This class is of no interest to most applications. It is useful
|
|---|
| 70 | for translation tools such as <a href="linguist-manual.html">Qt
|
|---|
| 71 | Linguist</a>. It is provided simply to make the API complete
|
|---|
| 72 | and regular.
|
|---|
| 73 | <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
|
|---|
| 74 | 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
|
|---|
| 75 | and the comment. Unless you plan to read and write messages
|
|---|
| 76 | yourself, you need not worry about the hash value.
|
|---|
| 77 | <p> QTranslatorMessage stores this triple or quadruple and the relevant
|
|---|
| 78 | translation if there is any.
|
|---|
| 79 | <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>.

| 83 |
|

| 84 | <p> Let (<em>h</em>, <em>c</em>, <em>s</em>, <em>m</em>) be the extended key. The possible

| 86 | <ul>
|
