Create QIcon in source code?

[Calicoder]

Howdy QT folks, been checking the official docs and don't see this error mentioned. I have a class named App with app.h and app.cpp like this:

app.h

private:
    QIcon goSign;
    QIcon stopSign;

app.cpp

goSign = QIcon(":/res/images/goSign.png");
stopSign = QIcon(":/res/images/stopSign.png");

The error I get is:
goSign uses undefined class QIcon
stopSign uses undefined class QIcon

Any ideas what is going on? Appreciate the help.

Did you include the QIcon header?

#include <QIcon>

Is your project configured to be a gui application? See the QIcon documentation

@mchinand Brilliant, that was it. I feel silly :-) Thanks so much
