[Solved] QFont doesn't seem to work properly

Endless

In the constructor below, I set the default font for all QLabels with the setStyleSheet function. I want the first label, faultLabel, to have a font other than the default, so I set it specifically. When I run the application, though, both labels have the default font set in the stylesheet. What am I doing wrong?
@
StatusBar::StatusBar(QWidget *parent) :
QWidget(parent)
{
QFrame *statusFrame = new QFrame(parent);
statusFrame->resize(1280, 42);
statusFrame->setStyleSheet("QLabel{ font: 24px "MS Shell Dlg 2", sans-serif; }");

QLabel *faultLabel = new QLabel(statusFrame);
faultLabel->setFont(QFont("Arial", 8));
faultLabel->move(300, 2);
faultLabel->setText("Fault:");

QLabel *dateLabel = new QLabel(statusFrame);
dateLabel->move(1080, 2);
dateLabel->setText("Date field");

}

If you use style sheets, member changes for font and palette are ignored.
You must the set the font on the specific label also via style sheet.

That makes sense, but when I add the following line to my setStyleSheet call, I get the same result:
@
"QLabel#faultLabel{ font: 10px "Arial", sans-serif; }");

That is because you have no object of that name, only a local variable :-)

@
StatusBar::StatusBar(QWidget *parent) :
QWidget(parent)
{
QFrame *statusFrame = new QFrame(parent);
statusFrame->resize(1280, 42);
statusFrame->setStyleSheet("QLabel{ font: 24px "MS Shell Dlg 2", sans-serif; }"
"QLabel#faultLabel{ font: 10px "Arial", sans-serif; }");

QLabel *faultLabel = new QLabel(statusFrame);
faultLabel->setFont(QFont("Arial", 8));
faultLabel->setObjectName("faultLabel"); // <-- this is the trick
faultLabel->move(300, 2);
faultLabel->setText("Fault:");

QLabel *dateLabel = new QLabel(statusFrame);
dateLabel->move(1080, 2);
dateLabel->setText("Date field");

}

Thanks - that really helped!
