Qt实现一个表格,具有excel功能?
使用QAxwidget,导入excel控件,然后窗口中的内容就是excel,你什么功能都不需要开发,直接用就是了。最后,把QAxwidget放入Qgraphicsscene中即可。
如何使用Qt来操作Excel
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-dynami...
QT获取excel 单元格位置
Qt可以通过QAxServer和QAxContainer库来获取excel单元格位置。
方法是:通过QAxServer获得Excel应用程序对象QAxObject,然后使用QAxObject打开相应的excel文档,找到指定的工作表,从里面读取指定位置上的单元格。
Qt操作Excel
如果设置后台启动报错的话,那提供一种无奈之选,就是,设置窗口可见,然后
excel-setProperty("WindowState", "xlMinimized");
将窗口最小化,将就一下
