The problem is the QChar...

 

Try this...

 

.arg( i, 2, 10, QChar( '10' )

I'm getting this error from the compiler:

 

pdf_viewer.cpp:697: error: ISO C++ says that these are ambiguous, even
though the worst conversion for the first is better than the worst
conversion for the second:

/usr/include/QtCore/qstring.h:129: note: candidate 1: QString
QString::arg(double, int, char, int, const QChar&) const

/usr/include/QtCore/qstring.h:625: note: candidate 2: QString
QString::arg(int, int, int, const QChar&) const

 

The line it is bitching about is:

 

tmpString.append(QString("%1").arg((int)i, 2, 10, '0') + "|");

 

Yes, I just realized that I can put the "|" inside the QString argument
but I'm trying to find out what is wrong with the line itself. i is an
int and is a counter in a for loop.

 

Basically, I'm trying to take an int and pad it to 2 digits and zero
filled. I'll use sprintf if I have to but I'd rather not.
