setStyleSheet via .qss file

ekato993

mainwindow constructor:

QFile file(":/Darkeum.qss");
file.open(QFile::ReadOnly);
QString styleSheet = QLatin1String(file.readAll());
setStyleSheet(styleSheet);

Darkeum.qss is in the project folder, and I also add it to the .pro file:

DISTFILES += \
    Darkeum.qss

I am getting this error: QIODevice::read (QFile, ":\Darkeum.qss"): device not open

If I am using the full file path it is working: "C:/...../Darkeum.qss"

@ekato993 Use resources as I suggested or construct absolute path to the file at runtime (using relative paths is dangerous as you can see, they depend on current working directory): https://doc.qt.io/qt-5/qstandardpaths.html

@ekato993 said in setStyleSheet via .qss file:

QFile file(":/Darkeum.qss");

How should this path work?
If you want to use a relative path then do (I assume the file is next to the executable and that that folder is working directory):

QFile file("Darkeum.qss");

But you should consider to use https://doc.qt.io/qt-5/resources.html
