[TOC] ## 中文不乱码 ``` #include "mainwindow.h" #include <QApplication> #include <QTextCodec> int main(int argc, char *argv[]) { QApplication a(argc, argv); QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8")); MainWindow w; w.show(); return a.exec(); } ``` 在qt5中添加 ``` QTextCodec::setCodecForLocale(QTextCodec::codecForName("UTF-8")); ```
