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.ts

language/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.ts

language/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_OBJECT

public:
    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);
}

7 其它

void QLinguist::on_ActionEn_Triggered()
{
	qDebug() << ".....";
	//qApp->installTranslator(&en);
	//ui.retranslateUi(this);

	//ui.lineEdit->setText(tr("图像路径为空!"));
}
