This code generated from Qt Designer,


QPalette palette;
QBrush brush(QColor(255, 255, 255, 255));
brush.setStyle(Qt::SolidPattern);
palette.setBrush(QPalette::Active, QPalette::Base, brush);
QBrush brush1(QColor(0, 0, 0, 255));
brush1.setStyle(Qt::SolidPattern);
palette.setBrush(QPalette::Active, QPalette::Window, brush1);
palette.setBrush(QPalette::Inactive, QPalette::Base, brush);
palette.setBrush(QPalette::Inactive, QPalette::Window, brush1);
palette.setBrush(QPalette::Disabled, QPalette::Base, brush1);
palette.setBrush(QPalette::Disabled, QPalette::Window, brush1);
Dialog->setPalette(palette);


Dialog - it's your MainWindow.

I think, this code is possible to optimize.

try this in your mainwindow class constructor:
tested code:

QPalette palette;
palette.setColor(backgroundRole(), Qt::black);
setPalette(palette);
