I would just like to say a few things about Qt and its awesomeness :p
Ok, so everything in Qt is based around the concept of events. This means that everything from the Window Manager wanting the window to be redrawn, to a mouse button being clicked, to the window being resized is done in events.
Here is some example code of drawing a circle in the middle of the window (200x200) when the window manager wants it.
void MainWindow::paintEvent(QPaintEvent *event)
QPen pen(Qt::blue, 2);
painter.drawEllipse(20, 20, 160, 160);
