1.1、QString转(int、float、double) // 转int QString strAge("18"); int age = strAge.toInt(); qDebug()<<age; // 转float QString strPI("3.14"); float PI = strPI.toFloat(); // 转double double dPI = strPI.toDouble(); qDebug()<<PI; 1.2、(int,float,double)转(QString) int...
int tmp=str.toInt(); 2、int转QString int tmp =100; QString str=QString::number(tmp); QString和char*的相互转换 1、QString转为char* QString str; char* ch; QByteArray ba = str.toLatin1(); // must ch=ba.data(); 或者直接 ch = str.toLatin1().data(); 但是这里可能会造成中文...

int dec=str.toInt(&ok,10); //dec=255 ; ok=rue int hex =str.toInt(&ok,16); //hex=255;ok=true; 1 2 3 4 2.常整形转换为Qstring形 long a =63; QString str=QString::number(a,16); //str=”3f”; QString str=QString::number(a,16).toUpper(); //str=”3F”; 1 2 3 ...
int 转 QString int m=1; QString b; b=QString::number(m) QString 转int QString a="1111" int b; b=a.toInt() char 转换为 QString char a='b'; QString str; str=QString(a); QString 转换为 char QString str="qq"; char *ch; ...
Qt中 int ,float ,double转换为QString有两种方法1.使用QString::number();如:long a = 63;QString s = QString::number(a, 10); // s == "63"QString t = QString
2. int 转 QString int a = 5; qDebug() << QString::number(a, 10); // "5" double b = 1.2; QString str; str.setNum(b); qDebug() << str; // "1.2" 1 2 3 4 5 6 7 3. QString 转 const char * QString str = "abc"; ...
1)int转化为string int aa = 30; stringstream ss; ss<<aa; string s1 = ss.str(); cout<<s1<<endl; // 30 2)string转化为int int a; sscanf("123","%D",&a); --- 原文:https://blog.csdn.net/u013360881/article/details/78878346 版权声明:本文为博主原创文章,...
Qt中QString和int类型之间的转化QString转int QString::toInt()例程：QString a;int b = a.toInt();同理也可以转化为浮点型 QString a;float b = a.toFloat();int转QString QString::number(int n, int base = 10)例程：int b;QString a = QString::number(b,10); 其中base为进制 还有...
1.使用 QString QString::number ( long n, int base = 10 ) [static]如:long a = 63; QString s = QString::number(a, 10); // s == "63"QString t = QString::number(a, 16).toUpper(); // t == "3F"2.使用 long a = 63; QString s = QString("%...
