+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 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.
