[Qt-interest] Locale input/output of custom doubleSpinbox Delegate

[Ben Swerts]

Hi Matthias,

You can do this using QLocale.
* When the data() function of your model is called with role ==
Qt::EditRole, just return a QVariant( double )
* When the data() function of your model is called with role ==
Qt::DisplayRole, return QVariant( QLocale::system()->toString( double ) )

If you want to convert a QString with a value in the locale, you can use
QLocale::system()->toDouble( QString ).

Hope it helps.
Greets,
