от целого числа до QString QT
Use QString::number():
int i = 42;
QString s = QString::number(i);
Prickly Pigeon
Use QString::number():
int i = 42;
QString s = QString::number(i);int i = 42;
QString s = QString::number(i);// Qt 5 + C++11
auto i = 13;
auto printable = QStringLiteral("My magic number is %1. That's all!").arg(i);
// Qt 5
int i = 13;
QString printable = QStringLiteral("My magic number is %1. That's all!").arg(i);
// Qt 4
int i = 13;
QString printable = QString::fromLatin1("My magic number is %1. That's all!").arg(i);QString s = QString::number(42.5, 'f', 1);
