Format decimal to realize align right ？

sonichy

The arg() can only format integer：

QString text1 = QString("%1").arg(b, 6, 10, QLatin1Char(' '));

alt text

QString text1 = QString::number(b1/1024.0,'f',2);  // can not fillChar
QString text2 = QString::number(b1/1024.0,'f',2);
painter.drawText(rect(), Qt::AlignLeft | Qt::AlignVCenter, text1 + "\n" + text2);

nope, see the Qt5 help for QString:

QString QString::arg(double a, int fieldWidth = 0, char format = 'g', int precision = -1, QChar fillChar = QLatin1Char( ' ' )) const
This function overloads arg().

so

QString test = QString("%1").arg(86400 / 1024.0, 6, 'f', 2, QLatin1Char(' '));

should do it right
