Example: Sorting a QStringList using QCollator
#include <QStringList>
#include <QCollator>
#include <QDebug>
int main( int argc, char *argv[] )
{
QStringList myStringList = (QStringList() << "abc123" << "ABc99" << "1234abcd");
QCollator sorter;
sorter.setNumericMode( true ); // Default is false
sorter.setCaseSensitivity( Qt::CaseInsensitive ); // Default is case sensitive
std::sort( myStringList.begin(), myStringList.end(), [&]( const QString& a, const QString& b ) {
return sorter.compare( a, b ) < 0;
} );
qDebug() << myStringList;
}
The code above should output the following:
- ("1234abcd", "ABc99", "abc123")
