QT编程技巧.QString和QDateTime之间的相互转换

1、QDateTime 转换为 QString

 

QString QDateTime::toString ( Qt::DateFormat format = Qt::TextDate ) const

 QString strBuffer;
 QDateTime time;

 time = QDateTime::currentDateTime();

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

 // strBuffer = 2010-07-02 17:35:00

 

2、QString 转换为 QDateTime

 

QDateTime QDateTime::fromString ( const QString & string, const QString & format )   [static]

 

 QString strBuffer;
 QDateTime time;

 strBuffer = "2010-07-02 17:35:00";

 time = QDateTime::fromString(strBuffer, "yyyy-MM-dd hh:mm:ss");
