tool.h头文件中:
#ifndef TOOL_H #define TOOL_H #include <QObject> class Tool; class Tool:public QObject{ public: static QString tenString2HexStr(QString message); }; #endif // TOOL_H
源文件中tool.cpp :
#include <tool.h> //数据转换参考 https://blog.csdn.net/biersibao/article/details/82884719 QString Tool::tenString2HexStr(QString message){ QString hexString=""; //"240,121,247" -----> [f0,79,f7] QStringList lis = message.split(','); for(int i = 0;i < lis.length();i++){ int intt = lis[i].toUInt(); QByteArray a = QByteArray::number(intt, 16); //f0 hexString += a; } // f079f7 return hexString; }
如何使用?在需要使用的cpp文件中导入头文件,并且以 类名:: 的形式引用静态函数.
#include <tool.h> ... void Connector::onReceivedMsg(const QString& message) { qInfo() << "socket接收数据: "<< Tool::tenString2HexStr(message); }
