在Qt中,将unsigned char数组转换为QString通常涉及将字节数据视为某种编码的字符串。最常见的是将字节数据视为UTF-8编码的字符串,因为QString内部使用Unicode编码,但它能够很好地处理UTF-8编码的字符串。 以下是一个分步骤的解决方案,包括代码示例: 1. 理解unsigned char数组和QString的数据结构 unsigned char数组是...
//unsiged char *转QString unsigned char *str = "fdd" ; char *str1 = (char *)str; QString str2 = QString(QLatin1String(str1)); //QString 转化成char * QString str = "fdd"; QByteArray ba = str.toLatin1(); unsigned char * str1 = (unsigned char *)ba.data;分类: Qt 好...
四、将unsigned char数组转为QString表示的16进制 unsigned char数组转为QString unsignedcharun_char[]{0xff,0xee,0xdd,0xcc,0xaa}; QString ucTos = QString(QByteArray((char*)un_char,5).toHex());
QString -> unsigned char* : QString str = "ABCD"; int length = str.length(); unsigned char* sequence = NULL;sequence =(unsigned char*)qstrdup(str.toAscii().constData()); delete[] sequence; - sequence length = 5 --> ['A'] ['B'] ['C'] ['D'] ['/0'] - sequence is now...

7. QString 与 char * 的转换 //QString 转 char *QString str;char*ch;QByteArray byte=str.toUtf8();ch=byte.data();QString str;std::string string=str.toStdString();constchar*ch=string.c_str();//char * 转 QStringconstchar*ch="hello";QStringstr(ch);constchar*ch="hello";QString...
