I would like to format an integer in a QString
. I would like to always have 6 numbers.
For example "1" should be "000001" and "12" should be "000012".
I try to do like with printf(%06d, number)
. So I wrote this
QString test;
test = QString("%06d").arg(QString::number(i));
qDebug()<<test;
i is implemented in a loop for
.
But it does not work since I have:
"0d" "1d" "2d" "3d"...
Does anyone know how to do this please?
To break up a string into a string list, we used the QString::split() function. The argument to split can be a single character, a string, or a QRegExp. To concatenate all the strings in a string list into a single string (with an optional separator), we used the join() function.
The QString class provides an abstraction of Unicode text and the classic C '\0'-terminated char array. More... All the functions in this class are reentrant when Qt is built with thread support.
Generally speaking: If you want to initialize a QString from a char*, use QStringLiteral . If you want to pass it to a method, check if that method has an overload for QLatin1String - if yes you can use that one, otherwise fall back to QStringLiteral .
String's argument support doesn't work like printf. It's all documented. What you want is:
QString test = QString("%1").arg(i, 6, 10, QLatin1Char('0'));
