i used the example code but the background color remained as the default one.
any idea?

Usually the code to change a widget's background color looks like this

QPalette palette = widget->palette(); // get current palette
 
palette.setColor(QPalette::Background, color); // modify palette
 
widget->setPalette(palette); // apply modified palette
 
widget->setAutoFillBackground(true); // tell widget to fill its background itself

QPalette palette = widget->palette(); // get current palette

palette.setColor(QPalette::Background, color); // modify palette

widget->setPalette(palette); // apply modified palette

widget->setAutoFillBackground(true); // tell widget to fill its background itself

To copy to clipboard, switch view to plain text mode 

Btw, you don't have to create a QStatusBar, QMainWindow::statusBar() will do that for you and always return the same instance
