C++/Qt5 Show underscore on button caption - Windows 10

[jimbo]

Hello,

Windows 10
Qt Creator 3.6.1
Based on Qt 5.6.0


void MainWindow:: on_button_clicked()
{
...
QPushButton *pb = new QPushButton("&Close", choice);
pb->setGeometry(22, g1->x() + g1->height() + 5, 70, 25);
QObject::connect(pb, SIGNAL(clicked()), this, SLOT(pb_clicked()));
...
}
Alt + C works.
The underline doesn't show on the 'C' in the button caption.
Is this a problem with the fonts in Windows 10?
Is there a way round it?

Regards

Edited - Changed Ctrl for Alt.

Does the ampersand show on the button? If not then Qt is probably doing the right thing with it. The lack of an underscore is probably then a function of the Windows theme.
Does the C gain an underline when hold down the Alt key? When you hover over or focus the button? When you do both?

Hello ChrisW67,


Does the ampersand show on the button?No.

Does the C gain an underline when hold down the Alt key?Yes.

When you hover over or focus the button?No.

I 'think' I have read somewhere that Windows 10 is not using True Type anymore???
I guess I'll have to wait for the Qt developers to catch up.

Regards
