+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
+(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.

+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).
