The QApplication font family is emtpy string in XP, the GUI's font can't display correctly

[Cpppro]

Every simpe code:

#include "xlsxdocument.h"

using namespace QXlsx;

int main(int argc, char *argv[]) { QApplication app(argc, argv);

QFile outFile("a.txt");
outFile.open(QIODevice::WriteOnly | QIODevice::Append);
QTextStream ts(&outFile);
ts << app.font().family() << "\r\n";

// without the follow line, everything works fine
QXlsx::Document xlsxW;

return 0;

}

Win10 : GOOD. XP: without using the QXlsx, everything is good. otherwise, app.font().family() is empty string.

Dear @Cpppro

That function seems to be caused by Qt's own functionality. Maybe.

I don't have an XP environment, so I couldn't test it.
