Trouble with relative paths for files

[squidge]

See QDir and QDir::cdUp

Basically, you can give QCoreApplication::applicationDirPath() to the constructor of QDir, then perform cdUp function on that object and retrieve new directory. If it's not possible to go further up (eg. if the application is in the root directory), the cdUp method will fail.

Also, you could output the result of your string concatenation (or go in debug mode) to be sure of what you're doing.
My guess is that you missed a "/" after application dir path

QString temp = QCoreApplication::applicationDirPath() + "/" + ".." + "/icon.png";
qDebug() << temp ;

QString temp = QCoreApplication::applicationDirPath() + "/" + ".." + "/icon.png";
qDebug() << temp ;
