while std has std::string, to change between them, use following code: // #include <QMessageBox>usingnamespacestd;// #include <fstream>#include<cassert>QStrings2q(std::string&str){autoqs=QString::fromLocal8Bit(QByteArray::fromRawData(str.c_str(),str.size()));returnqs;}QStrings2q...
QString s = "www.amin-ahmadi.com"; First convert it tostd::stringand then use itsc_strmethod, like this: s.toStdString().c_str()
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...

tojson的最后两个参数控制 Qt支持 修改config.h,开启XTOSTRUCT_QT这个宏 当前支持 QString/QMap/QList/QVector xml bson libconfig 如果需要这些功能,需要修改config.h来开启 不支持直接转换vector/map之类的,需要放结构体里面 由于xml/libconfig不支持用纯数字作为key,所以如果需要用map<int, xxx>,那么key需要用...
我们将简单地使用一个 Q 字符串并使用 Qstring 类的 “toInt” 预构建方法将其转换为十六进制,然后提供一个 OK 指针来检查转换是否已成功执行。 Ok指针仅用于检查错误,不会影响QString int到HexaDecimal的转换。 示例 C++14 // use the qtcore tool to run this code#include<bits/stdc++.h>usingnamespace...
#include <bits/stdc++.h> using namespace std; // Source class, i.e // class that will be converted to another class class Class_type_one { string a = "GeeksforGeeks"; public: // Member function which returns // string type data string get_string() { return (a); } // Member ...
