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

1. QString strBuffer; 
2. QDateTime time; 
3.  
4. time = QDateTime::currentDateTime(); 
5.  
6. strBuffer = time.toString("yyyy-MM-dd hh:mm:ss"); 
7.  
8. // strBuffer = 2010-07-02 17:35:00

1. QString strBuffer; 
2. QDateTime time; 
3.  
4. time = QDateTime::currentDateTime(); 
5.  
6. strBuffer = time.toString("yyyy-MM-dd hh:mm:ss"); 
7.  
8. // strBuffer = 2010-07-02 17:35:00 

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]

1. QString strBuffer; 
2. QDateTime time; 
3.  
4. strBuffer = "2010-07-02 17:35:00"; 
5.  
6. time = QDateTime::fromString(strBuffer, "yyyy-MM-dd hh:mm:ss");
