QHostAddress address(string); 11、QString转unsigned char QString string; bool ok; unsigned char uch = string.toInt(&ok, 16); 12、unsigned char转QString unsigned char uch; QString string = QString::number(uch,16); 13、int转QString int m; QString string; string=QString::number(m); ...
2 > char * 转 QByteArray char *ch;QByteArray byte;byte = QByteArray(ch); 8、 QString 转换为char* QString提供的字符编码集的转换函数将会返回一个constchar*类型版本的QByteArray,即构造函数QByteArray(constchar*)构造的QByteArray对象。QByteArray类具有一个字节数组,它既可以存储原始字节(raw bytes),也...
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]);}ui->textBrowser->append(str)...
unsigned char *ret = (unsigned char *)ch; 1 2 6. const unsigned char * 转 QString const unsigned char str[5] = {'t', 'e', 's', 't'}; string s = (char *)str; qDebug() << QString::fromStdString(s); 1 2 3
port=(unsignedshort)ui->LE_port->text().toShort();//获取端口号 1.QString转char * 先将QString转换为QByteArray,再将QByteArray转换为char *。 注意:不能用下面的转换形式char *mm = str.toLatin1().data();。因为这样的话,str.toLatin1()得到的QByteArray类型结果就不能保存,最后转换,mm的值就...
