How to close an opened document?

[Ruffletuft]

Hello!I'm working on my project with QXlsx. Recently I found that even if I closed all the windows in the program,the process did not disappear.I debugged for a long time,finally found that it's because of using Document::load() .In my program,.xlsx is always be opened but not always be saved. I read the source code of QXlsx but still not know :can an opened file close automatically?Or there is any API?

Maybe the problem is not about closing file.But _Document::load() _ does make my program not normally exit.Here is some info may help.My program crushed here.And I don't use class QExplicitlySharedDataPointer.Any suggestion please?

Dear @andthen255 There is no function mentioned. The crash will be registered as an issue.

Hi. The HelloWorld Demo (in Qt 5.9.1). After "return 0;" code is called, it crashed. #120 the gdb end in ~QMap().

my code end the ~qmap as yours，did you solve the question？

Is it a multi-threaded problem? I don't know exactly.

I think the problem in HelloWorld is the the same as in #156 not in .load() but in .save() try the solution https://github.com/QtExcel/QXlsx/issues/156#issuecomment-824631407

I don't know the cause now. But I will keep this issue.

Sorry for the late reply. I am currently working in a place where there is no internet.
