+\membersection{wxWindow::HasExtraStyle}\label{wxwindowhasextrastyle}
+
+\constfunc{bool}{HasExtraStyle}{\param{int }{exFlag}}
+
+Returns \texttt{true} if the window has the given \arg{exFlag} bit set in its
+extra styles.

+\helpref{SetExtraStyle}{wxwindowsetextrastyle}
+
+
+\membersection{wxWindow::HasFlag}\label{wxwindowhasflag}
+
+\constfunc{bool}{HasFlag}{\param{int }{flag}}
+
+Returns \texttt{true} if the window has the given \arg{flag} bit set.
+
+
+\membersection{wxWindow::HasMultiplePages}\label{wxwindowhasmultiplepages}
+
+\constfunc{virtual bool}{HasMultiplePages}{\void}
+
+This method should be overridden to return \texttt{true} if this window has
+multiple pages. All standard class with multiple pages such as
+\helpref{wxNotebook}{wxnotebook}, \helpref{wxListbook}{wxlistbook} and
+\helpref{wxTreebook}{wxtreebook} already override it to return \texttt{true}
+and user-defined classes with similar behaviour should do it as well to allow
+the library to handle such windows appropriately.
+
+
+\membersection{wxWindow::HasScrollbar}\label{wxwindowhasscrollbar}
+
+\constfunc{virtual bool}{HasScrollbar}{\param{int }{orient}}
+
+Returns {\tt true} if this window has a scroll bar for this orientation.
+
+\wxheading{Parameters}
+
+\docparam{orient}{Orientation to check, either {\tt wxHORIZONTAL} or {\tt wxVERTICAL}.}
+
+
+\membersection{wxWindow::HasTransparentBackground}\label{wxwindowhastransparentbackground}
+
+\constfunc{virtual bool}{HasTransparentBackground}{\void}
+
+Returns \true if this window background is transparent (as, for example, for
+wxStaticText) and should show the parent window background.
+
+This method is mostly used internally by the library itself and you normally
+shouldn't have to call it. You may, however, have to override it in your
+wxWindow-derived class to ensure that background is painted correctly.
