1、往 ini文件写信息void CurveDlg::on_pushButton_2_clicked() //write{QSettings *qSetIninew QSettings(test.ini,QSettings::IniFormat);qSetIni-setValue(1/COM,Com3);qSetIni-setValue(2/Baud,921600);qSetIni-setValue(3/Path,E:\\TEMP_DATA);qSetIni-setValue(3/Filename,1.raw);}2、从ini文件读数据void CurveDlg::on_pushButton_3_clicked( )//read{QSettings *qReadIninew QSettings(test.ini,QSettings::IniFormat);QString str1qReadIni-value(1/COM).toString();QString str2qReadIni-value(2/Baud).toString();QString str3qReadIni-value(3/Path).toString();QString str4qReadIni-value(3/Filename).toString();}3、ini文件如图
