QFileDialog 中保存一个普通excel文件，参数设置

QString fileName = QFileDialog::getSaveFileName(NULL,"Save File","./saveResult","Excel File (*.xls)");

fileName.replace("/","\\");

QFile file(fileName);

if(file.exists()) {

m_excel = new QExcel(fileName, this);

return false;

}

QAxWidget excel("Excel.Application");

excel.setProperty("Visible",false);

QAxObject * workbooks = excel.querySubObject("WorkBooks");

workbooks->dynamicCall("Add");

QAxObject * workbook = excel.querySubObject("ActiveWorkBook");

workbook->dynamicCall("SaveAs (const QString&,int,const QString&,const QString&,bool,bool)",fileName,56,QString(""),QString(""),false,false);

workbook->dynamicCall("Close (Boolean)", false);

excel.dynamicCall("Quit (void)");

//有几个值得一提的是

//1.getSaveFileName(NULL,"Save File","./saveResult","Excel File (*.xls)")    第三个参数如果直接为. 保存文件名为空， ./saveResult 这样写的话，就有一个默认的名字

//2.

//*******

QAxWidget excel("Excel.Application");

excel.setProperty("Visible",false);

QAxObject * workbooks = excel.querySubObject("WorkBooks");

workbooks->dynamicCall("Add");

QAxObject * workbook = excel.querySubObject("ActiveWorkBook");

workbook->dynamicCall("SaveAs (const QString&,int,const QString&,const QString&,bool,bool)",fileName,56,QString(""),QString(""),false,false);

workbook->dynamicCall("Close (Boolean)", false);

excel.dynamicCall("Quit (void)");

*********//

这里是调用QAxObject 对象的内容，生成一个excel文件。

//3  workbook->dynamicCall("Close (Boolean)", false);   这种调用方式为， 引号内的函数有几个参数， 后面就需要写几个参数， 参数对应的内容要根据帮助文档，自己写
