qt 字体设置

1.首先将字体（我选择windows下的宋体simsun.ttf）copy至qte的lib/font目录下
2.设置环境变量export QT_QWS_FONTDIR=/mnt/nfs/qte-arm/lib/fonts/
3.在函数里指定字体

eg:测试例程

1 #include <QtGui/QApplication>
  2 #include <QtGui/QWidget>
  3 #include <QtGui/QLabel>
  4 #include <QtCore/QTextCodec>
  5 #include <QtGui/QPushButton>
  6 #include <QtGui/QVBoxLayout>
  7 #include <QFont>
  8 int main(int argc, char* argv[])
  9 {
 10 QApplication app(argc, argv);
 11 // app.setFont(QFont("simsun"));

 12
 13 QFont font;
 14 font.setPointSize(26);
 15 font.setFamily(("simsun"));
 16 app.setFont(font);
 17
 18 QTextCodec::setCodecForTr(QTextCodec::codecForName("utf-8"));
 19 QWidget* pWidget = new QWidget;
 20 QLabel label(pWidget);
 21 // pWidget.showMaximized();

 22 pWidget->showMaximized();
 23 label.setText(QObject::tr("北京欢迎您!"));
 24 QPushButton* btn = new QPushButton(QObject::tr("close!"), pWidget);
 25 QVBoxLayout* layout = new QVBoxLayout;
 26 layout->addWidget(&label);
 27 layout->addWidget(btn);
 28 pWidget->setLayout(layout);
 29 QObject::connect(btn, SIGNAL(clicked()), pWidget, SLOT(close()));
 30 pWidget->show();
 31 return app.exec();
 32 }
