有下面一段代码，编译运行后却是乱码
- #include <QApplication>
- #include <QHBoxLayout>
- #include <QSlider>
- #include <QSpinBox>
- #include <QLabel>
- #include <QObject>
- //#include <QTextCodec>
- int main(int argc, char *argv[])
- {
- QApplication app(argc, argv);
- QWidget *window = new QWidget;
- window->setWindowTitle(QObject::trUtf8("输入你的年龄"));
- QSpinBox *spinBox = new QSpinBox;
- QSlider *slider = new QSlider(Qt::Horizontal);
- spinBox->setRange(0, 130);
- slider->setRange(0, 130);
- QObject::connect(spinBox, SIGNAL(valueChanged(int)),
- slider, SLOT(setValue(int)));
- QObject::connect(slider, SIGNAL(valueChanged(int)),
- spinBox, SLOT(setValue(int)));
-
- spinBox->setValue(35);
- QHBoxLayout *layout = new QHBoxLayout;
- layout->addWidget(spinBox);
- layout->addWidget(slider);
-
- QLabel* label=new QLabel(QObject::trUtf8("你的年龄:"));
-
- QVBoxLayout* mainLayout=new QVBoxLayout;
- mainLayout->addWidget(label);
- mainLayout->addLayout(layout);
-
- window->setLayout(mainLayout);
- window->resize(300,50);
- window->show();
- return app.exec();
- }
于是我把QObject::trUtf8换成了QObject::tr，又加了一行QTextCodec::setCodecForTr(QTextCodec::codecForName("UTF8"));
还是乱码，
但我把"UTF8" 换成 "GB2312" 是正常的
这该怎么解释啊
