Qt CMake 国际化相关配置

文章目录

- 更新ts文件
- 发布ts文件

本来用qmake使用pro文件很简单的一件事，结果用cmake折腾了半天。
何必呢~

参考：QT6.3 CMake 多语言切换

这是我的

cmake_minimum_required(VERSION 3.16)project(testQml3_6 VERSION 0.1 LANGUAGES CXX)set(CMAKE_AUTOMOC ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)find_package(Qt6 6.2 COMPONENTS Quick REQUIRED LinguistTools)set(OUR_TS_FILES testQml3_6_zh_CN.ts testQml3_6_de.ts)qt_add_executable(apptestQml3_6main.cpp${OUR_TS_FILES}
)qt_create_translation(QM_FILES ${CMAKE_SOURCE_DIR} ${OUR_TS_FILES})qt_add_qml_module(apptestQml3_6URI testQml3_6VERSION 1.0QML_FILES main.qml 
)qt_add_lupdate(apptestQml3_6 TS_FILES ${OUR_TS_FILES})
qt_add_lrelease(apptestQml3_6TS_FILES ${OUR_TS_FILES}QM_FILES_OUTPUT_VARIABLE qm_files)
qt_add_resources(apptestQml3_6 "translations"PREFIX "/"BASE "${CMAKE_CURRENT_BINARY_DIR}"FILES "${QM_FILES}")set_target_properties(apptestQml3_6 PROPERTIESMACOSX_BUNDLE_GUI_IDENTIFIER my.example.comMACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}MACOSX_BUNDLE TRUEWIN32_EXECUTABLE TRUE
)target_link_libraries(apptestQml3_6PRIVATE Qt6::Quick)install(TARGETS apptestQml3_6BUNDLE DESTINATION .LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR})

在这里插入图片描述

要改四个地方
1, 添加 LinguistTools
2，添加ts文件的包含
3，创建ts文件
4，将生成的翻译好的 qm 文件放到资源目录下

#include <QGuiApplication>
#include <QQmlApplicationEngine>#include <QLocale>
#include <QTranslator>int main(int argc, char *argv[])
{QGuiApplication app(argc, argv);QTranslator translator;const QStringList uiLanguages = QLocale::system().uiLanguages();for (const QString &locale : uiLanguages) {const QString baseName = "testQml3_6_" + QLocale(locale).name();
//        if (translator.load(":/i18n/" + baseName)) {
//            app.installTranslator(&translator);
//            break;
//        }if (translator.load(":/" + baseName)) {app.installTranslator(&translator);break;}}QQmlApplicationEngine engine;const QUrl url(u"qrc:/testQml3_6/main.qml"_qs);QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,&app, [url](QObject *obj, const QUrl &objUrl) {if (!obj && url == objUrl)QCoreApplication::exit(-1);}, Qt::QueuedConnection);engine.load(url);QString t_str = QObject::tr("hello4");return app.exec();
}
