On my machine sorting in QTableWidget is case insensitive by default, so I assume you want a case sensitive sort: that is words starting with A-Z sort before words starting a-z.
Make a subclass of QTableWidgetitem and override the default operator<() to do a case-sensitive comparison. Use that subclass for the items you add to the table.
Here is a complete program. The left column sorts one way, the right column the default.
@#include <QtGui>
#include <QDebug>
class MyItem: public QTableWidgetItem
{
public:
MyItem(const QString &text, int type = Type):
QTableWidgetItem(text, type)
{ }
bool operator< ( const QTableWidgetItem & other ) const {
return (QString::compare(
data(Qt::DisplayRole).toString(),
other.data(Qt::DisplayRole).toString(), Qt::CaseSensitive ) < 0 );
}
};
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QStringList values;
values << "Z" << "b" << "B" << "a" << "A";
QTableWidget tw(5,2);
for (int r = 0; r < 5; ++r) {
tw.setItem(r, 0, new MyItem(values.at(r))); // left column uses our sorting
tw.setItem(r, 1, new QTableWidgetItem(values.at(r))); // right column uses default
}
tw.setSortingEnabled(true);
tw.show();
return app.exec();
}
