QDateTime转换为QString

QDateTime转换为QString

QDateTime time =QDateTime::currentDateTime();

QString sda_name="E:/"+chrom_mac+time.toString("yyyyMMddhhmmss")+".sda";

time.toString("yyyyMMddhhmmss")将time转化成了string类型，格式为"yyyyMMddhhmmss"

QString转换为QDateTime

QString str = "2016-05-30 12:35:00"; 
QDateTime time= QDateTime::fromString(str, "yyyy-MM-dd hh:mm:ss");

QString str = "2016-05-30 12:35:00"; 
QDateTime time= QDateTime::fromString(str, "yyyy-MM-dd hh:mm:ss"); 

QString strBuffer;  QDateTimeQDateTime::fromString ( const QString & string,const QString & format)
