我有一个新问题，我正在设计一个应用程序而且我不知道如何将项目导出到excel文件，在我使用带有QSortFilteredProxyModel的QTreeView的代码中，我包含了一个用于在QLineEdit中编写的文本的过滤器，我需要导出过滤后可以看到的所有项目。但是，如何将这些项目添加到列表中，以便将它们导出到Excel文件中？
如果有人能帮助我，我会非常感激。
我的坏英语

您可以使用QSortFilterProxyModel中的休眠函数：
rowCount（），columnCount（）和index（），然后使用返回的索引来获取数据：
rowCnt = self.proxyModel.rowCount()
colCnt = self.proxyModel.columnCount()
for row in range(0, rowCnt):
for col in range(0, colCnt):
modelIndex = self.proxyModel.index(row, col)
print modelIndex.data().toString()
