| − | | + | | text = [https://github.com/Slicer/Slicer/wiki/I18N This page has been moved to GitHub.] |

| − | =QT-based Internationalization= | |
| − | Internationalization is well supported in QT. A lot of modules of Slicer are developed on QT. This has set a good ground for the internationalization of Slicer.
| |
| − | *basic idea
| |
| − | In Qt, tr() is one of the static public members of QObject class, which returns a translated version of input sourceText.
| |
| − | QString QObject::tr ( const char * sourceText, const char * disambiguation = 0, int n = -1 ) [static]
| |
| − | tr() will search the translation in a so-called translation file. If nothing is found, then the sourceText instead of the translated version will be displayed directly.
| |
| − | *translation file template
| |
| − | The following is an example of the translation file, from English to Chinese.
| |
| − | <?xml version="1.0" encoding="utf-8"?>
| |
| − | <!DOCTYPE TS>
| |
| − | <TS version="2.0" language="zh_CN">

| |
| − | In the above example, all the texts are within the scope of qSlicerMainWindow class. That's why 'qSlicerMainWindo' occurs in section 'name'.
| |
| − | | |
| − | *The following modifications are are needed:
| |
| − | | |
| − | In file \Slicer4\Base\QTCore\qSlicerCoreApplication.h, add the following line:
| |
| − | #include <QTranslator>
| |
| − | In file \Slicer4\Applications\SlicerQT\main.cxx (around line#230), add the following lines:
| |
| − | static QTranslator* translator;
| |
| − | if (translator != NULL)
| |
| − | {
| |
| − | qApp->removeTranslator(translator);
| |
| − | delete translator;
| |
| − | translator = NULL;
| |
| − | }
| |
| − | QString langCode= argv[1];
| |
| − | translator = new QTranslator;
| |
| − | QString qmFilename = "lang_" + langCode;
| |
| − | if (translator->load(qmFilename))
| |
| − | {
| |
| − | qApp->installTranslator(translator);
| |
| − | }
| |
| − | | |
| − | =Scripted Module=
| |
| − | Some modules are implemented in Python. Endoscopy is one of the typical examples. In endoscopy.py, if we change the code in line#10
| |
| − | parent.titel = “Endoscopy”
| |
| − | to
| |
| − | parent.title = slicer.app.translate(self.__class__.__name__, "Endoscopy")
| |
| − | then "Endoscopy" can be shown in other languages.Similarily, other displayable strings can be handled in the same way.
