QString s = "www.amin-ahmadi.com"; First convert it tostd::stringand then use itsc_strmethod, like this: s.toStdString().c_str()
在Qt中,可以使用.toUtf8()或.toLatin1()函数来获取一个QByteArray对象,然后通过.constData()函数获得其对应的const char*指针。 例如,你可以尝试以下方式: intsizeWritten=send(it.key(),strAddName.toUtf8().constData(),strAddName.toUtf8().size(),0); 在这个示例中,我们首先使用.toUtf8()将QStrin...
const char *QString2char(QString str) { QByteArray byteArray; const char *cstr; byteArray = str.toUtf8(); cstr = byteArray.constData(); return(cstr); }This is the sample method, how we can use Qt : Convert QString to char function above :QString mystring; const char *char_data...

How to convert a QString to unicode object in python 2?I had this problem to solve, and I tried to find the safest way. This program illustrates the s
namespace nlohmann { template<> struct adl_serializer<QString> { static void to_json(json &j, const QString &s) { j = s.toStdString(); } static void from_json(const json &j, QString &s) { s = QString::fromStdString(j.get<std::string>()); } }; template<typename T> struc...
fgets(f1,6,out);fgets(f2,6,out);这两句的形参类型是char*, int, FILE*, 但是实参是QString, int, FILE* ,不能匹配。改为：fgets(f1.toLatin1(),6,out);fgets(f2.toLatin1(),6,out);
自定义类型的本质是string类型 需要实现这些函数: std::string format() const; 用于将对象转为字符串 void parse(const std::string&); 用于将字符串转为对象 最后用typedef XType 完成自定义类型的定义 以下代码是一个IPv4的例子 #include<iostream>#include"x2struct/x2struct.hpp"usingnamespacestd;// 只是...
