How to convert int to QString ?

Question

Hey guys .. Just a simple question .. Is there an QString function which takes and int and outputs its QString form ?

Answer 1

Use QString::number():

int i = 42;
QString s = QString::number(i);

Answer 2

In it's simplest form, use the answer of Georg Fritzsche

For a bit advanced, you can use this,

QString QString::arg ( int a, int fieldWidth = 0, int base = 10, const QChar & fillChar = QLatin1Char( ' ' ) ) const

Get the documentation and an example here..

Answer 3

And if you want to put it into string within some context, forget about + operator. Simply do:

int i = 13; QString printable = QString("My magic number is %1. That's all!").arg(i)

Answer 4

I always use QString::setNum().

int i = 10;
double d = 10.75;
QString str;
str.setNum(i);
str.setNum(d);

setNum() is overloaded in many ways. See QString class reference.
