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)...
qDebug() << str2; // "hello world !" 1 2 3 4 5 6 7 5. const char * 转 unsigned char * const char *ch = "hello world !"; unsigned char *ret = (unsigned char *)ch; 1 2 6. const unsigned char * 转 QString const unsigned char str[5] = {'t', 'e', 's', 't'}...
