LoadPackage and Streaming #182

Closed bascyr closed 5 years ago

bascyr commented 5 years ago

Hi, I'd like to shiow with a QProgressBar the loading state of a file xls.

I suppose that all streams happen when the file is fixed in the Document constructor.

QXlsx::Document xfile(c:/"test.xls");

Which method inside xlsdocument.cpp can be useful?

Thanks. Cyrille

As the operation of loading the the document is totally synchronous there's no feature to provide feedback support. Best thing is to show an undefined progress bar as described in http://doc.qt.io/qt-5/qprogressbar.html

If minimum and maximum both are set to 0, the bar shows a busy indicator instead of a percentage of steps. This is useful, for example, when using QNetworkAccessManager to download items when they are unable to determine the size of the item being downloaded.
