对于涉及中文情况,也可以先将QString转换为标准库string类型,然后再将string转换为char*。如下: QString str; std::stringstr =filename.toStdString();constchar* ch = str.c_str(); QT中unsigned char转QString的方法 unsigned char是无符号字符,代表的范围为0-255,转QString要通过int来牵线,下面直接上代码...
//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;...
//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...
unsigned char* 转qstring,unsignedchar*ch;std::stringstr=(char*)ch;QStringsstr=QString::fromStdString(str);
unsigned char* ch; QString str=""; str=str.append(ch); 或者str+=ch; 你就这样用就可以了,没有问题的,要是真的还有问题就把ch先转成QChar
extern static声明头.如果不加public ,函数默认为私有函数,调用就会出错。 [DllImport("CO ...
Qt下面,字符串都用QString,确实给开发者提供了方便,想想VC里面定义的各种变量类型,而且函数参数类型五花八门,经常需要今年新那个类型转换 Qt再使用第三方开源库时,由于库的类型基本上都是标准的类型,字符串遇的多的就是Char*类型 在Qt下...
因为char*最后都有一个‘/0’作为结束符,而采用QString::toLatin1()时会在字符串后面加上‘/0’...
Qt unsigned char *与QString之间的相互转换 //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 =...
