wxWindow is the base class for all windows. Any children of the window will be deleted
automatically by the destructor before the window itself is deleted.
-Please note that we documented a number of handler functions (OnChar(), OnMouse() etc.) in this
-help text. These must not be called by a user program and are documented only for illustration.
-On several platforms, only a few of these handlers are actually written (they are not always
-needed) and if you are uncertain on how to add a certain behaviour to a window class, intercept
-the respective event as usual and call \helpref{wxEvent::Skip}{wxeventskip} so that the native
-platform can implement its native behaviour or just ignore the event if nothing needs to be
-done.

-The purpose of this call is to provide a safer way of destroying a window than using

-provides a way to simulate a manual close of a window, which may or may not be implemented by

+\membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
+
+\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}
+void MyWindow::OnInternalIdle()
+{
+ if (wxUpdateUIEvent::CanUpdate(this))
+ UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
