Question

Qt编程。接收到的数据可以在textBrowser中正确显示，但是无法正确保存到文本文档中，怎样解决这个问题？

void GPSdata::GetData(QByteArray rec,GPSdata &gps)

｛........
}
void GPSdata::WriteData(GPSdata gps)
{

QFile file("test.txt");

if(!file.open(QIODevice::WriteOnly))

{

qDebug()<<"can't open file for writing";

return ;

}

QTextStream out(&file);

out<<"UTC time "<<"hour:"<<gps.time.hour<<" minute:"<<gps.time.minute

<<" "<<"second:"<<gps.time.second;

out<<" status:"<<gps.status;

out<<" latitude:"<<gps.latitude.degree<<" "<<gps.latitude.minute;

out<<" longitude:"<<gps.longitude.degree<<" "<<gps.longitude.minute;

out<<" heading:"<<gps.heading;

out<<" speed:"<<gps.speed;

out<<" UTC date "<<"day:"<<gps.date.day<<" month:"<<gps.date.month

<<" "<<"year:"<<gps.date.year;

out<<" mode:"<<gps.mode;
}

void GPSdata::init()
{

time.hour = 0;

time.minute = 0;

time.second= 0.0;

date.day = 0;

date.month = 0;

date.year = 0;

latitude.degree = 0;

latitude.minute = 0.0;

longitude.degree = 0;

longitude.minute = 0.0;

heading = 0.0;

speed = 0.0;

}

你忘记关闭文件了

应该怎样解决？我编程不是很熟。

追答

写入文件完成后调用file.close();就行了
