Qt Painter
QPainter provides highly optimized functions to do most of the drawing GUI programs require. It can draw everything from simple lines to
Qt Images And Fonts
Qt provides four classes for handling image data: QImage, QPixmap, QBitmap and QPicture. QImage is designed and optimized for I/O, and for direct pixel access and
Widgets in Qt
The widget is the atom of the user interface: it receives mouse, keyboard and other events from the window system, and paints
I/O In Qt
Qt encapsulates the more generalized notion of byte streams in its QIODevice class, which is the parent class for QFile, as well as network I/O
