+
+        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:

+            class MyWidget : public wxWindow
+            {
+            public:

+                 windows (wxFrame and wxDialog classes) as the others

+                The close handler should check whether the window is being deleted
+                forcibly, using wxCloseEvent::CanVeto, in which case it should
+                destroy the window using wxWindow::Destroy.

-        By "intelligently" the following is meant: by default, all windows use their

-        However if some of the parents attributes are explicitly (that is, using

-        attribute hadn't been explicitly set for this window itself, then this
-        window takes the same value as used by the parent.
-        In addition, if the window overrides ShouldInheritColours() to return @false,
-        the colours will not be changed no matter what and only the font might.
+        @param accept
+            If @true, the window is eligible for drop file events.
+            If @false, the window will not accept drop file events.

 
 

-        This rather complicated logic is necessary in order to accommodate the
-        different usage scenarios. The most common one is when all default attributes
-        are used and in this case, nothing should be inherited as in modern GUIs
-        different controls use different fonts (and colours) than their siblings so
-        they can't inherit the same value from the parent. However it was also deemed
-        desirable to allow to simply change the attributes of all children at once by
-        just changing the font or colour of their common parent, hence in this case we
-        do inherit the parents attributes.

+        current font size.
+
+        The default implementation simply returns ::wxDefaultSize and

+        you must override it when implementing a custom window class.
+
+        Notice that the best size returned by this function is cached
+        internally, so if anything that results in the best size changing (e.g.
+        change to the control contents) happens, you need to call
+        InvalidateBestSize() to notify wxWidgets about it.
