The precision range of double

[wysota]

I just looked into the signature and the parameters of the method, as such it returns me the string only. Again if i click on the column header of the tableview it gives me string compare only. correct me if Iam wrong.

So you didn't implement anything, just assumed it wouldn't work anyway?

I would rather put it this way, I started with the process and did not get how to change the precision.

QStyledItemDelegate::displaytext(...) takes QVariant and the QLocale.

After setting up this delegate to my model, this displaytext is called for showing the text on the view. But here i stuck up, as how to draw all the decimals.

Hmm... I even told you which method to use to get the desired output... I really don't understand what is so hard there to understand...

QString myDelegate::displayText(const QVariant &val, const QLocale &locale) const {
    if(val.type()==QVariant::Double) return locale.toString(val.toDouble(), 'g', 12); // or QString::number(val.toDouble(), 'g', 12)
    return QStyledItemDelegate::displayText(val, locale);
}

QString myDelegate::displayText(const QVariant &val, const QLocale &locale) const {
    if(val.type()==QVariant::Double) return locale.toString(val.toDouble(), 'g', 12); // or QString::number(val.toDouble(), 'g', 12)
    return QStyledItemDelegate::displayText(val, locale);
}
