Qt中操作excel | 易学教程

最近有一个把检测结果导出到excel中的任务，由于对qt比较熟悉，所以打算使用qt来实现。查了一下，使用qt下自带的QAxObject类，实现还是比较简单的。

首先需要在pro文件中添加axcontainer

QT       += core gui axcontainer

然后添加包含文件

#include <QAxObject>

如下是代码的具体实现：

void MainWindow::exportexcel(VRecord vrecord) {     QAxObject *excel = NULL;     QAxObject *workbooks = NULL;     QAxObject *workbook = NULL;     excel = new QAxObject("Excel.Application");     excel->dynamicCall("SetVisible(bool)", true);     workbooks = excel->querySubObject("WorkBooks");      workbook = workbooks->querySubObject("Open(QString&)",           "D:/build-QT_EXPORT-Desktop_Qt_5_9_0_MSVC2015_32bit-Debug/template.xls");      QAxObject * worksheets = workbook->querySubObject("WorkSheets");      //int iWorkSheet = worksheets->property("Count").toInt();     //qDebug() << QString::fromLocal8Bit("Excel文件中表的个数: %1").arg(QString::number(iWorkSheet));      QAxObject * worksheet = worksheets->querySubObject("Item(int)", 1);      /*     表格范围和行数列数     QAxObject * usedrange = worksheet->querySubObject("UsedRange");      QAxObject * rows = usedrange->querySubObject("Rows");     int iRows = rows->property("Count").toInt();     qDebug() << QString::fromLocal8Bit("行数为: %1").arg(QString::number(iRows));      QAxObject * columns = usedrange->querySubObject("Columns");     int iColumns = columns->property("Count").toInt();     qDebug() << QString::fromLocal8Bit("列数为: %1").arg(QString::number(iColumns));      int iStartRow = rows->property("Row").toInt();     qDebug() << QString::fromLocal8Bit("起始行为: %1").arg(QString::number(iStartRow));      int iColumn = columns->property("Column").toInt();     qDebug() << QString::fromLocal8Bit("起始列为: %1").arg(QString::number(iColumn));     */      /*     读出数据     QAxObject *range1 = worksheet->querySubObject("Range(QString)", "F6");     QString strRow6Col6 = range1->property("Value").toString();     qDebug() << QString::fromLocal8Bit("第6行，第6列的数据为：") + strRow6Col6;     */       //写入数据      //QAxObject *range2 = worksheet->querySubObject("Range(QString)", "F6");     //range2->setProperty("Value", "aaaa");     for(int i = 0;i<vrecord.size();i++)     {         QString cora = "A" + QString::number(i+2);         QAxObject *rangea = worksheet->querySubObject("Range(QString)", cora);         rangea->setProperty("Value", vrecord.at(i).id);          QString corb = "B" + QString::number(i+2);         QAxObject *rangeb = worksheet->querySubObject("Range(QString)", corb);         rangeb->setProperty("Value", vrecord.at(i).dt.toString("yyyy/MM/dd HH:mm:ss"));          QString corc = "C" + QString::number(i+2);         QAxObject *rangec = worksheet->querySubObject("Range(QString)", corc);         rangec->setProperty("Value", vrecord.at(i).res);     }      //另存为文件     QString filepath = QString::fromLocal8Bit("D:/build-QT_EXPORT-Desktop_Qt_5_9_0_MSVC2015_32bit-Debug/报表输出结果.xls");     workbook->dynamicCall("SaveAs(const QString&)",QDir::toNativeSeparators(filepath));     workbook->dynamicCall("Close()");     excel->dynamicCall("Quit()");      if (excel)     {         delete excel;         excel = NULL;     }      QMessageBox::information(0 ,                           QString::fromLocal8Bit("提示") , QString::fromLocal8Bit("报表生成成功"),                           QMessageBox::Ok | QMessageBox::Default ,                           0 );  }

本函数实现的功能是打开一个模板文件，把传入的记录写到指定的位置，并自动完成另存为的操作。这个程序在跑的过程中会打开excel。使用这种方法有一个缺点，那就是系统必须按照微软的excel，wps不行。
