+\membersection{wxWindow::SetEventHandler}\label{wxwindowseteventhandler}
+
+\func{void}{SetEventHandler}{\param{wxEvtHandler* }{handler}}
+
+Sets the event handler for this window.
+
+\wxheading{Parameters}
+
+\docparam{handler}{Specifies the handler to be set.}
+
+\wxheading{Remarks}
+
+An event handler is an object that is capable of processing the events
+sent to a window. By default, the window is its own event handler, but
+an application may wish to substitute another, for example to allow
+central implementation of event-handling for a variety of different
+window classes.
+
+It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
+this sets up a chain of event handlers, where an event not handled by one event handler is
+handed to the next one in the chain.

+\membersection{wxWindow::SetExtraStyle}\label{wxwindowsetextrastyle}
+
+\func{void}{SetExtraStyle}{\param{long }{exStyle}}
+
+Sets the extra style bits for the window. The currently defined extra style
+bits are:
+
+\twocolwidtha{5cm}%
+\begin{twocollist}\itemsep=0pt
+\twocolitem{\windowstyle{wxWS\_EX\_VALIDATE\_RECURSIVELY}}{TransferDataTo/FromWindow()
+and Validate() methods will recursively descend into all children of the
+window if it has this style flag set.}
+\twocolitem{\windowstyle{wxWS\_EX\_BLOCK\_EVENTS}}{Normally, the command
+events are propagared upwards to the window parent recursively until a handler
+for them is found. Using this style allows to prevent them from being
+propagated beyond this window. Notice that wxDialog has this style on by
+default for the reasons explained in the
+\helpref{event processing overview}{eventprocessing}.}
+\twocolitem{\windowstyle{wxWS\_EX\_TRANSIENT}}{This can be used to prevent a
+window from being used as an implicit parent for the dialogs which were
+created without a parent. It is useful for the windows which can disappear at
+any moment as creating childs of such windows results in fatal problems.}
