Qt MainWindow Dark theme

Question

I'm learning Qt and do you know to set black theme for mainwindow at Qt? I think that it's doing by css stylesheet or anything like this. I hope at your help. Sorry for bad English!

Answer 1

You can change it from its stylesheet.

QMainWindow{
     background-color: rgb(0, 0, 0) 
}

Just add this styling in your stylesheet, and it will work.

Answer 2

You can do it:

QApplication::setStyle(const QString & style);

You may do it on qss stylesheet (it's like css) For create your style file read more on Qt docs: http://doc.qt.io/Qt-5/stylesheet-reference.html
