解决QT中中文字符乱码问题，只需在main文件中添加几行代码即可。
#include <QtGui/QApplication>
#include <QTextCodec>
#include "widget.h"
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
QTextCodec::setCodecForTr(QTextCodec::codecForName("GB2312"));
QTextCodec::setCodecForLocale(QTextCodec::codecForName("GB2312"));
QTextCodec::setCodecForCStrings(QTextCodec::codecForName("GB2312"));
Widget w;
w.show();
return a.exec();
}
#include <QtGui/QApplication>#include <QTextCodec>#include "widget.h"int main(int argc, char *argv[])
{QApplication a(argc, argv);
QTextCodec::setCodecForTr(QTextCodec::codecForName("GB2312")); QTextCodec::setCodecForLocale(QTextCodec::codecForName("GB2312")); QTextCodec::setCodecForCStrings(QTextCodec::codecForName("GB2312")); Widget w; w.show();return a.exec();
}
