}// 使用示例 QString getEnglishFontName(const QString& chineseName) {static QMap<QString, QString> mapping = createFontMapping();return mapping.value(chineseName, chineseName); // 找不到则返回原名 }
调用：
#include <QFontComboBox>connect(ui.fontComboBox, &QFontComboBox::currentFontChanged, this, &CVRTextSymbolDialog::_slotFontChanged);void _slotFontChanged(const QFont font) {string strFont = getEnglishFontName(font.family()).toLocal8Bit() ; }
这个的 strFont 就是英文映射的字体库名称，可以在程序其他地方调用
