+\func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE_UI_NONE}}
+
+This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
+the window. The particular implementation depends on the window; for
+example a wxToolBar will send an update UI event for each toolbar button,
+and a wxFrame will send an update UI event for each menubar menu item.
+You can call this function from your application to ensure that your
+UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
+are concerned). This may be necessary if you have called 
+\helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or 
+\helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
+limit the overhead that wxWindows incurs by sending update UI events in idle time.
+
+{\it flags} should be a bitlist of one or more of the following values.
+
+\begin{verbatim}
+enum wxUpdateUI
+{
+    wxUPDATE_UI_NONE          = 0x0000, // No particular value
+    wxUPDATE_UI_RECURSE       = 0x0001, // Call the function for descendants
+    wxUPDATE_UI_FROMIDLE      = 0x0002  // Invoked from On(Internal)Idle
+};
+\end{verbatim}
+
+If you are calling this function from an OnInternalIdle or OnIdle
+function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
+this tells the window to only update the UI elements that need
+to be updated in idle time. Some windows update their elements
+only when necessary, for example when a menu is about to be shown.
+The following is an example of how to call UpdateWindowUI from
+an idle function.
+
+\begin{verbatim}
