One way i found was using QTextEdit

QTextEdit *textEdit = centralWidget()->findChild<QTextEdit *>("textEdit");

QTextCursor textCursor(textEdit->document());
textCursor.select(QTextCursor::LineUnderCursor);

textEdit->setAutoFillBackground(true);
QPalette palette;
palette.setColor(QPalette::Background,QColor(200,200,200));
textEdit->setPalette(palette);
