+        Sets the background style of the window.
+
+        The default background style is @c wxBG_STYLE_ERASE which indicates that
+        the window background may be erased in @c EVT_ERASE_BACKGROUND handler.
+        This is a safe, compatibility default; however you may want to change it
+        to @c wxBG_STYLE_SYSTEM if you don't define any erase background event
+        handlers at all, to avoid unnecessary generation of erase background
+        events and always let system erase the background. And you should
+        change the background style to @c wxBG_STYLE_PAINT if you define an
+        @c EVT_PAINT handler which completely overwrites the window background as
+        in this case erasing it previously, either in @c EVT_ERASE_BACKGROUND
+        handler or in the system default handler, would result in flicker as
+        the background pixels will be repainted twice every time the window is
+        redrawn. Do ensure that the background is entirely erased by your
+        @c EVT_PAINT handler in this case however as otherwise garbage may be left
+        on screen.
+
+        Notice that in previous versions of wxWidgets a common way to work
+        around the above mentioned flickering problem was to define an empty
+        @c EVT_ERASE_BACKGROUND handler. Setting background style to
+        @c wxBG_STYLE_PAINT is a simpler and more efficient solution to the same
+        problem.
+
+
+        Under wxGTK and wxOSX, you can use ::wxBG_STYLE_TRANSPARENT to obtain
+        full transparency of the window background. Note that wxGTK supports
+        this only since GTK 2.12 with a compositing manager enabled, call
+        IsTransparentBackgroundSupported() to check whether this is the case.
+
+        Also, on order for @c SetBackgroundStyle(wxBG_STYLE_TRANSPARENT) to
+        work, it must be called before Create(). If you're using your own
+        wxWindow-derived class you should write your code in the following way:
+        @code
+            class MyWidget : public wxWindow
+            {
+            public:
+                MyWidget(wxWindow* parent, ...)
+                    : wxWindow() // Use default ctor here!
+                {
+                    // Do this first:
+                    SetBackgroundStyle(wxBG_STYLE_TRANSPARENT);
+
+                    // And really create the window afterwards:
+                    Create(parent, ...);
