A wxScrolledWindow will normally scroll itself and therefore its child windows as well. It
might however be desired to scroll a different window than itself: e.g. when designing a
-spreadsheet, you'll normally only have to scroll the (usually white) cell area, whereas the
+spreadsheet, you will normally only have to scroll the (usually white) cell area, whereas the
(usually grey) label area will scroll very differently. For this special purpose, you can
call \helpref{SetTargetWindow}{wxscrolledwindowsettargetwindow} which means that pressing
the scrollbars will scroll a different window.
Note that the underlying system knows nothing about scrolling coordinates, so that all system
-functions (mouse events, expose events, refresh calls etc) as well as the position of subwindows
+functions (mouse events, expose events, refresh calls etc) as well as the position of subwindows
are relative to the "physical" origin of the scrolled window. If the user insert a child window at
position (10,10) and scrolls the window down 100 pixels (moving the child window out of the visible
area), the child window will report a position of (10,-90).
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.
+CalcScrolledPosition(0, 10, \&xx, \&yy) will return 0 in yy.

The first pair of parameters give the number of pixels per `scroll step', i.e. amount
Call this function to tell wxScrolledWindow to perform the actually scrolling on
a different window (not on itself).
