How to change QDateTime format to YYYY/MM/dd HH:mm:ss.

Have you tried
QDateTime::fromString
QDateTime::toString
as shown here ?

Header can be changed through setHorizontalHeaderLabels .

Hi,

A QStyledItemDelegate comes to mind for that or a QIdentityProxyModel.

Hi,

U can u yyyy/MM/dd HH:mm:ss
year in small letters,
toString() method is present for changing as desired.

Thanks,

I'm with Samuel here. Subclass QStyledItemDelegate.

class DateFormatDelegate : public QStyledItemDelegate{
Q_OBJECT
Q_PROPERTY(QString dateFormat READ dateFormat WRITE setDateFormat NOTIFY dateFormatChanged)
Q_DISABLE_COPY(DateFormatDelegate)
public:
explicit DateFormatDelegate(QObject *parent = Q_NULLPTR)
:QStyledItemDelegate(parent),m_dateFormat("yyyy-MM-dd"){}
DateFormatDelegate(const QString dtFormat,QObject *parent = Q_NULLPTR)
:QStyledItemDelegate(parent),m_dateFormat(dtFormat){}
QString displayText(const QVariant &value, const QLocale &locale) const Q_DECL_OVERRIDE{
switch(value.type()){
case QMetaType::QDate:
return locale.toString(value.toDate(),m_dateFormat);
case QMetaType::QDateTime:
return locale.toString(value.toDateTime(),m_dateFormat);
case QMetaType::QTime:
return locale.toString(value.toTime(),m_dateFormat);
default:
return QStyledItemDelegate::displayText(value,locale);
}
}
const QString& dateFormat() const {return m_dateFormat;}
void setDateFormat(const QString& dtFormat){
if(m_dateFormat==dtFormat) return;
m_dateFormat=dtFormat;
dateFormatChanged(m_dateFormat);
}
Q_SIGNAL void dateFormatChanged(const QString& dtFormat);
private:
QString m_dateFormat;
};
