QPushButton in QMessageBox missing key shortcut underline on initial display

I don't think this is a system default, since Qt paints its buttons itself and does not use native widgets.
I say this because if I look into a Qt dialog using Spy++, it has no children, so no native objects.
The reason for this design decision is probably that there was no other way to assure identical functionality across all platforms.

Therefore this is a Qt default which in my opinion is badly chosen, since the Windows default is just the opposite - to always underline button shortcuts in dialogs.

my windows 7 do not have underscore as default.
only when i press alt.
That goes for buttons and menus.
Except some common file open dialog it seems :)

Which wouldn't stop it to honor the default system behavior, would it?

As @mrjj noted:

Which had been my experience as well.

The reason for this design decision is probably that there was no other way to assure identical functionality across all platforms.

This design decision, if memory serves me, happened some time when Qt 4 was developed (which should be about 10 years ago) and it was mostly done because using native handles is costly as hell, and UIs tend to just eat up resources if you have a handle for each tiny thing. And it's been working just fine, if I may add.

Kind regards.

I did it putting this in main.cpp and that's all folks ;-)

QApplication a(argc, argv);
a.setStyle("fusion");
