+        Call this function to tell wxScrolled to perform the actual scrolling
+        on a different window (and not on itself).
+
+        This method is useful when only a part of the window should be
+        scrolled. A typical example is a control consisting of a fixed header
+        and the scrollable contents window: the scrollbars are attached to the
+        main window itself, hence it, and not the contents window must be
+        derived from wxScrolled, but only the contents window scrolls when the
+        scrollbars are used. To implement such setup, you need to call this
+        method with the contents window as argument.
+
+        Notice that if this method is used, GetSizeAvailableForScrollTarget()
+        method must be overridden.

+        to account for the size of the non-scrollable parts of the main window
+        and return only the size available for the scrollable window itself.

+        vertical component of @a size.
