Qt操作excel

QAxWidget excel("Excel.Application");
1) 显示当前窗口：
excel.setProperty("Visible", true);
2) 更改 Excel 标题栏：
excel.setProperty("Caption", "Invoke Microsoft Excel");
3) 添加新工作簿：
QAxObject * workbooks = excel.querySubObject("WorkBooks");
workbooks->dynamicCall("Add");
4) 打开已存在的工作簿：
workbooks->dynamicCall("Open (const QString&)", QString("c:/test.xls"));
5) 获取活动工作簿：
QAxObject * workbook = excel.querySubObject("ActiveWorkBook");
6) 获取所有的工作表：
QAxObject * worksheets = workbook->querySubObject("WorkSheets");
7) 获取工作表数量：
int intCount = worksheets->property("Count").toInt();
8) 获取第一个工作表：
QAxObject * worksheet = workbook->querySubObject("Worksheets(int)", 1);
9) 获取cell的值：
QAxObject * range = worksheet->querySubObject("Cells(int,int)", 1, 1 );
