What is your output? QWidget/QLabel/QGraphicsView/QPushButton/terminal?Quote:

Qwidget ,,,,
u need some specific text display QWidgets to display the string ex: QLabel QLineEdit . if strictly u want it to display in qwidget u have to override the paintEvent http://qt-project.org/search/tag/paintevent of QWidget and display the text using QPainter::drawText , which in turn is a hectic operation for a small task .
