1 运行环境

         VS2017+QT

2 命令用法

lupdate 更新翻译文件        生成 .ts 文件

用法:

lupdate ./ -ts language/QLinguist_en.ts language/QLinguist_zh.ts language/QLinguist_xf.tslanguage/QLinguist_en.ts //language/目录 按照实际需求更改

lrelease 发布更新文件        生成 .qm 文件

用法:

lrelease language/QLinguist_en.ts language/QLinguist_zh.ts language/QLinguist_xf.tslanguage/QLinguist_en.ts // language/ 目录 按照实际需求更改

3 软件界面

4 vs配置

        项目-> 属性->生成事件->生成后事件->输入

lupdate ./ -ts language/QLinguist_en.ts language/QLinguist_zh.ts language/QLinguist_xf.ts
lrelease language/QLinguist_en.ts language/QLinguist_zh.ts language/QLinguist_xf.ts

5 .h代码

#pragma once#include <QtWidgets/QMainWindow>
#include "ui_QLinguist.h"
#include <QTranslator>
#include <QDebug>#pragma execution_character_set("utf-8")
class QLinguist : public QMainWindow
{Q_OBJECTpublic:QLinguist(QWidget *parent = nullptr);~QLinguist();private slots:void on_ActionTriggered();void on_ActionXf_Triggered();void on_ActionEn_Triggered();private:Ui::QLinguistClass ui;QString strFilePath = "";QTranslator zh;QTranslator xf;QTranslator en;
};

6 .cpp代码

#include "QLinguist.h"QLinguist::QLinguist(QWidget *parent): QMainWindow(parent)
{ui.setupUi(this);setWindowTitle("多语言切换Demo CSDN 双子座断点 V1.0 https://blog.csdn.net/qq_37529913?type=blog");strFilePath = "C:/Users/dream/source/repos/QLinguist/QLinguist/language/";zh.load(strFilePath + "QLinguist_zh.qm");xf.load(strFilePath + "QLinguist_xf.qm");en.load(strFilePath + "QLinguist_en.qm");connect(ui.action, SIGNAL(triggered()), SLOT(on_ActionTriggered()));connect(ui.action_2, SIGNAL(triggered()), SLOT(on_ActionXf_Triggered()));connect(ui.action_3, SIGNAL(triggered()), SLOT(on_ActionEn_Triggered()));}QLinguist::~QLinguist()
{}void QLinguist::on_ActionTriggered() 
{qDebug() << ".....";qApp->installTranslator(&zh);ui.retranslateUi(this);
}void QLinguist::on_ActionXf_Triggered()
{qDebug() << ".....";qApp->installTranslator(&xf);ui.retranslateUi(this);
}void QLinguist::on_ActionEn_Triggered()
{qDebug() << ".....";qApp->installTranslator(&en);ui.retranslateUi(this);
}

void QLinguist::on_ActionEn_Triggered()
{qDebug() << ".....";//qApp->installTranslator(&en);//ui.retranslateUi(this);//ui.lineEdit->setText(tr("图像路径为空!"));
}
