-    @class wxNotebookEvent
-
-    This class represents the events generated by a notebook control: currently,
-    there are two of them. The PAGE_CHANGING event is sent before the current
-    page is changed. It allows the program to examine the current page (which
-    can be retrieved with
-    wxNotebookEvent::GetOldSelection) and to veto the page
-    change by calling wxNotifyEvent::Veto if, for example, the
-    current values in the controls of the old page are invalid.
-
-    The second event - PAGE_CHANGED - is sent after the page has been changed and
-    the program cannot veto it any more, it just informs it about the page change.
-
-    To summarize, if the program is interested in validating the page values
-    before allowing the user to change it, it should process the PAGE_CHANGING
-    event, otherwise PAGE_CHANGED is probably enough. In any case, it is probably
-    unnecessary to process both events at once.

+
+    On Windows XP, the default theme paints a gradient on the notebook's pages.
+    If you wish to suppress this theme, for aesthetic or performance reasons,
+    there are three ways of doing it.
+    You can use @c wxNB_NOPAGETHEME to disable themed drawing for a particular
+    notebook, you can call wxSystemOptions::SetOption to disable it for the
+    whole application, or you can disable it for individual pages by using
+    SetBackgroundColour().
+
+    To disable themed pages globally:
+    @code
+    wxSystemOptions::SetOption("msw.notebook.themed-background", 0);
+    @endcode
+
+    Set the value to 1 to enable it again.
+    To give a single page a solid background that more or less fits in with the
+    overall theme, use:
+    @code
+    wxColour col = notebook->GetThemeBackgroundColour();
+    if (col.IsOk())
+    {
+        page->SetBackgroundColour(col);
+    }
+    @endcode
+
+    On platforms other than Windows, or if the application is not using Windows
+    themes, GetThemeBackgroundColour() will return an uninitialised colour object,
+    and the above code will therefore work on all platforms.
