How to use Qt::CaseInsensitive in Qtablewidget data sorting?

mathi77in

i am using QTablewidget. i want to sort one of the column in QTableWidget. Column data have CaseInsensitive(upper and lower). when I do setSortingEnabled() true it only sorts it in alphabetic order for Uppercase.

Miss out the small letter alphabetic data. i want sort the Column data from both (upper and lower) alphabetic order. If any sample code or url pls?

How to apply Qt::CaseInsensitive in Qtablewidget sorting?

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();
}
