Conversion relations

A time conversion (QDateTime, QString, time_t)

1, QDateTime converted to QString

QString strBuffer;
QDateTime time;
time = QDateTime::currentDateTime();
strBuffer = time.toString("yyyy-MM-dd hh:mm:ss");

2, QString convert QDateTime

QString strBuffer;
QDateTime time;
strBuffer = "2018-06-06 14:05:00";
time = QDateTime::fromString(strBuffer, "yyyy-MM-dd hh:mm:ss");

3, QDateTime convert time_t

time_t  curTime; 
QDateTime time; 
time = QDateTime::fromTime_t(curTime);

4, QDateTime convert time_t

time_t curTime; 
QDateTime team; 
curTime time.toTime_t = ();

 

Two, QModelIndex and QStandardItem

1, QModelIndex converted QStandardItem

QStandardItem * item=QStandardItemModel::​itemFromIndex(const QModelIndex & index) const

2, QStandardItem converted QModelIndex

QModelIndex model = QStandardItem::​index() const
