+\texttt{GetXXX()} methods may be overloaded (as, for example,
+\helpref{GetSize}{wxwindowgetsize} or
\helpref{GetClientSize}{wxwindowgetclientsize}). In this case, the overloads
are non-virtual because having multiple virtual functions with the same name
results in a virtual function name hiding at the derived class level (in

variants if it overrides any of them). To allow overriding them in the derived

+
+The other one is that in the future this function could return different
+results, for example it might return a different font for an ``Ok'' button
+than for a generic button if the users GUI is configured to show such buttons

+\membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}
+
+\func{void}{InheritAttributes}{\void}
+
+This function is (or should be, in case of custom controls) called during
+window creation to intelligently set up the window visual attributes, that is
+the font and the foreground and background colours.
+
+By ``intelligently'' the following is meant: by default, all windows use their
+own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
+if some of the parents attributes are explicitly (that is, using
+\helpref{SetFont}{wxwindowsetfont} and not
+\helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
+corresponding 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 \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
+to return \false, the colours will not be changed no matter what and only the
+font might.
+
+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.

+exist in several sizes which correspond to the elements of wxWindowVariant

+\begin{verbatim}
+enum wxWindowVariant
+{
+ wxWINDOW_VARIANT_NORMAL, // Normal size
+ wxWINDOW_VARIANT_SMALL, // Smaller size (about 25 % smaller than normal )

+ wxWINDOW_VARIANT_LARGE, // Large size (about 25 % larger than normal )
+};

+be used to change this.
