"""
A ribbon button bar is similar to a traditional toolbar.
Description
===========
It contains one or more buttons (button bar buttons, not :class:`Button`), each of which
has a label and an icon. It differs from a :class:`toolbar` in several ways:
- Individual buttons can grow and contract.
- Buttons have labels as well as bitmaps.
- Bitmaps are typically larger (at least 32x32 pixels) on a button bar compared to
a tool bar (which typically has 16x15).
- There is no grouping of buttons on a button bar
- A button bar typically has a border around each individual button, whereas a tool
bar typically has a border around each group of buttons.
Events Processing
=================
This class processes the following events:
======================================== ========================================
Event Name Description
======================================== ========================================
``EVT_RIBBONBUTTONBAR_CLICKED`` Triggered when the normal (non-dropdown) region of a button on the button bar is clicked.
``EVT_RIBBONBUTTONBAR_DROPDOWN_CLICKED`` Triggered when the dropdown region of a button on the button bar is clicked. :meth:`RibbonButtonBarEvent.PopupMenu() <RibbonButtonBarEvent.PopupMenu>` should be called by the event handler if it wants to display a popup menu (which is what most dropdown buttons should be doing).

This function sends one or more :class:`UpdateUIEvent` to the window.
The particular implementation depends on the window; for example a :class:`ToolBar` will
send an update UI event for each toolbar button, and a :class:`Frame` 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 :class:`UpdateUIEvent` handlers are concerned). This may be
necessary if you have called :meth:`UpdateUIEvent.SetMode` or :meth:`UpdateUIEvent.SetUpdateInterval`
to limit the overhead that wxWidgets incurs by sending update UI events in idle time.
:param integer `flags`: should be a bitlist of one or more of ``wx.UPDATE_UI_NONE``,
``wx.UPDATE_UI_RECURSE`` or ``wx.UPDATE_UI_FROMIDLE``.
If you are calling this function from an `OnInternalIdle` or `OnIdle` function, make sure
you pass the ``wx.UPDATE_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 :meth:`~RibbonButtonBar.UpdateWindowUI` from an idle function::
