qt unsigned char数组转qstring 文心快码BaiduComate 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...
QString str2 = QString(QLatin1String(str1)); //QString 转化成char * QString str = "fdd"; QByteArray ba = str.toLatin1(); unsigned char * str1 = (unsigned char *)ba.data;
//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...
QString转为char QString str ="abcd";char*chr = str.toLatin1().data();char*chr2 = qPrintable(str); 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)...
QHostAddress转QString QHostAddress address;QString string = address.toString(); unsigned char转QString unsigned char uch;QString string = QString::number(uch,16); 五、int类型的转换 int转QString int m;QString string;string=QString::number(m);...
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...
qt上的char * 和 QString互相转换 使用Qt开发嵌入式时,常引用一些C语言的驱动,那就涉及到QString和char *之间的互相转换,方法如下,直接上代码: // char[]转QStringunsignedcharbuf[3]={0x2,0x56,0xff};QString str;for(inti=0;i<sizeof(buf)/sizeof(buf[0]);i++){str+=QString::number(buf[i...
QStringstring;QHostAddressaddress(string); 11、QString转unsigned char QStringstring;boolok;unsignedcharuch =string.toInt(&ok,16); 12、unsigned char转QString unsignedcharuch;QStringstring= QString::number(uch,16); 13、int转QString intm;QStringstring;string=QString::number(m); ...
QString str1 = QString::fromLocal8Bit(ch); qDebug() << str1; // "hello world !" QString str2(ch); qDebug() << str2; // "hello world !" 1 2 3 4 5 6 7 5. const char * 转 unsigned char * const char *ch = "hello world !"; ...
QString Qstr;std::stringstr =Qstr.toStdString();constchar* c = str.c_str(); 6、QByteArray转换为QString QByteArray buf ="123456"; QString str= QString(buf); 7、unsigned char转换为QString unsignedcharch[10] ="sssssssss"; QString str= QString().asprintf("%s", ch);...
