|
|---|
| 31 |
|
|---|
| 32 | \section1 Overview
|
|---|
| 33 |
|
|---|
| 34 | Strings in QML can be marked for translation using the qsTr(), qsTranslate(),
|
|---|
| 35 | QT_TR_NOOP(), and QT_TRANSLATE_NOOP() functions.
|
|---|
| 36 |
|
|---|
| 37 | For example:
|
|---|
| 38 | \qml
|
|---|
| 39 | Text { text: qsTr("Pictures") }
|
|---|
| 40 | \endqml
|
|---|
| 41 |
|
|---|
| 42 | These functions are standard QtScript functions; for more details see
|
|---|
| 43 | QScriptEngine::installTranslatorFunctions().
|
|---|
| 44 |
|
|---|
| 45 | QML relies on the core internationalization capabilities provided by Qt. These
|
|---|
| 46 | capabilities are described more fully in:
|
|---|
| 47 | \list
|
|---|
| 48 | \o \l {Internationalization with Qt}
|
|---|
| 49 | \o \l {Qt Linguist Manual}
|
|---|
| 50 | \endlist
|
|---|
| 51 |
|
|---|
| 52 | You can test a translation with the \l {QML Viewer} using the -translation option.
|
|---|
| 53 |
|
|---|
| 54 | \section1 Example
|
|---|
| 55 |
|
|---|
| 56 | First we create a simple QML file with text to be translated. The string
|
|---|
| 57 | that needs to be translated is enclosed in a call to \c qsTr().
|
|---|
| 58 |
|
|---|
| 59 | hello.qml:
|
|---|
| 60 | \qml
|
|---|
| 61 | import QtQuick 1.0
|
|---|
| 62 |
|
|---|
| 63 | Rectangle {
|
|---|
| 64 | width: 200; height: 200
|
|---|
| 65 | Text { text: qsTr("Hello"); anchors.centerIn: parent }
|
|---|
| 66 | }
|
|---|
| 67 | \endqml
|
|---|
| 68 |
|
|---|
| 69 | Next we create a translation source file using lupdate:
|
|---|
| 70 | \code
|
|---|
| 71 | lupdate hello.qml -ts hello.ts
|
|---|
| 72 | \endcode
|
|---|
| 73 |
|
|---|
| 74 | Then we open \c hello.ts in \l{Qt Linguist Manual} {Linguist}, provide
|
|---|
| 75 | a translation and create the release file \c hello.qm.
|
|---|
| 76 |
|
|---|
| 77 | Finally, we can test the translation:
|
|---|
| 78 | \code
|
|---|
| 79 | qmlviewer -translation hello.qm hello.qml
|
|---|
| 80 | \endcode
|
|---|
| 81 |
|
|---|
| 82 |
|
|---|
| 83 | You can see a complete example and source code in the \l{declarative/i18n}{QML Internationalization example}.
