Cannot open resource file

Question

Here is my code:

QFile test(\"://needle.png\"); // also tried :/needle.png :\\needle.png :\\\\needle.png

if(test.open(QFile::ReadOnly)) {
    qDebug() <&         


        

Answer 1

I had exactly the same problem. Running qmake again finally worked (build -> run qmake).

Answer 2

Does the URL notation

QFile test("qrc:///needle.png");

work for you?

Answer 3

I removed the project.user.pro file, reopened QT. And it chose the kit and rebuilt. Working now.
