Fill Screen with a single colour.

[QbelcorT]

Hi,
I used this to get rid of the window bar.

setFrameStyle(QFrame::NoFrame); // QFrame::Panel | QFrame::Raised 
setWindowFlags(Qt::FramelessWindowHint);

setFrameStyle(QFrame::NoFrame); // QFrame::Panel | QFrame::Raised 
setWindowFlags(Qt::FramelessWindowHint);

To copy to clipboard, switch view to plain text mode 

You may try to use QCoreApplication::setPalette
I used the following for changing my background color. Set a pixmap or use a QColor for the Brush.

QWSServer::setBackground(QBrush(pix));	// set default background color

QWSServer::setBackground(QBrush(pix));	// set default background color
