\func{void}{OnSize}{\param{wxSizeEvent\& }{event}}
-Called when the window has been resized.
+Called when the window has been resized. This is not a virtual function; you should
+provide your own non-virtual OnSize function and direct size events to it using EVT\_SIZE
+in an event table definition.
\wxheading{Parameters}
\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.}
