30 | \title QML Internationalization
|
---|
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}.
