Translates the logical coordinates to the device ones. For example, if a window is
scrolled 10 pixels to the bottom, the device coordinates of the origin are (0, 0)
(as always), but the logical coordinates are (0, 10) and so the call to
CalcScrolledPosition(0, 0, \&xx, \&yy) will return 10 in yy.

Sent to the window when the window must be refreshed.
For more details, see \helpref{wxWindow::OnPaint}{wxwindowonpaint}.
The default implementation for wxScrolledWindow's OnPaint handler is simply:
\begin{verbatim}
void wxScrolledWindow::OnPaint(wxPaintEvent& event)
{
wxPaintDC dc(this);
PrepareDC(dc);
OnDraw(dc);
}
\end{verbatim}
\membersection{wxScrolledWindow::OnScroll}\label{wxscrolledwindowonscroll}
\func{void}{OnScroll}{\param{wxScrollEvent\& }{event}}
Override this function to intercept scroll events. This
member function implements the default scroll behaviour. If
you do not call the default function, you will have to manage
all scrolling behaviour including drawing the window contents
at an appropriate position relative to the scrollbars.
For more details, see \helpref{wxWindow::OnScroll}{wxwindowonscroll}.

\helpref{wxScrollEvent}{wxscrollevent}
Instead of overriding this function you may also just process the paint event
in the derived class as usual, but then you will have to call PrepareDC()
yourself.
