一、应用程序中文化

1).Qt安装目录下有一个目录translations/,在此目录下有qt_zh_CN.ts和 qt_zh_CN.qm
把它们拷贝到你的工程目录下。

2).在main函数加入下列代码:
QTranslator translator(0); 
translator.load("qt_zh_CN.qm");
QApplication app(argc, argv);
app.installTranslator(&translator);
别忘了头文件包含QTranslator

二、应用程序实现重启

void CGUIfeaturesList::on_restartBtn_clicked()
{
    qApp->quit();
    QProcess::startDetached(qApp->applicationFilePath(), QStringList());
}

三、使用QSS样式表文件

QFile file("./style.qss");
    file.open(QFile::ReadOnly);
    QString styleSheet = QLatin1String(file.readAll());
    qApp->setStyleSheet(styleSheet);
    file.close();

四、使用程序启动界面

QPixmap pixmap("./start.png");
    QSplashScreen splash(pixmap);
    splash.show();
    QTime dieTime = QTime::currentTime().addMSecs(3000);
    while( QTime::currentTime() < dieTime )
       a.processEvents(QEventLoop::AllEvents, 100);
    
    MainWindow w;
    w.move((QApplication::desktop()->width() - w.width())/2,(QApplication::desktop()->height() - w.height())/2);
    w.show();
    splash.finish(&w);

main.cpp文件参考如下:

#include <QTextCodec>
#include <QPixmap>
#include <QSplashScreen>
#include <QTime>
#include <QTextCodec>
#include <QFile>
#include <QTranslator>
#include <QtGui>
int main(int argc, char *argv[])
{
    QTranslator translator(0);//标准对话框中文化
    translator.load("qt_zh_CN.qm");
    QApplication a(argc, argv);
    a.installTranslator(&translator);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForCStrings(QTextCodec::codecForName("UTF-8"));
    QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8"));
//    QTextCodec::setCodecForTr(QTextCodec::codecForName(QTextCodec::codecForLocale()->name()));
//    QTextCodec::setCodecForLocale(QTextCodec::codecForName(QTextCodec::codecForLocale()->name()));
//    QTextCodec::setCodecForCStrings(QTextCodec::codecForName(QTextCodec::codecForLocale()->name()));
    QFile file("./style.qss");
    file.open(QFile::ReadOnly);
    QString styleSheet = QLatin1String(file.readAll());
    qApp->setStyleSheet(styleSheet);
    file.close();
    QPixmap pixmap("./start.png");
    QSplashScreen splash(pixmap);
    splash.show();
    QTime dieTime = QTime::currentTime().addMSecs(3000);
    while( QTime::currentTime() < dieTime )
       a.processEvents(QEventLoop::AllEvents, 100);
    CGUIfeaturesList w;
    w.move((QApplication::desktop()->width() - w.width())/2,(QApplication::desktop()->height() - w.height())/2);
    w.show();
    splash.finish(&w);
    
    return a.exec();
}
