"""
`auibar.py` contains an implementation of :class:`AuiToolBar`, which is a completely owner-drawn
toolbar perfectly integrated with the AUI layout system. This allows drag and drop of
toolbars, docking/floating behaviour and the possibility to define "overflow" items
in the toolbar itself.

The default theme that is used is :class:`AuiToolBar`, which provides a modern,
glossy look and feel. The theme can be changed by calling :meth:`AuiToolBar.SetArtProvider`.

        :param `event`: the event to process.

        :note: Normally, your application would not call this function: it is called
         in the wxPython implementation to dispatch incoming user interface events
         to the framework (and application).
         However, you might need to call it if implementing new functionality (such as
         a new control) where you define new event types, as opposed to allowing the
         user to override functions.

         An instance where you might actually override the :meth:`ProcessEvent` function is where
         you want to direct event processing to event handlers not normally noticed by
         wxPython. For example, in the document/view architecture, documents and views
         are potential event handlers. When an event reaches a frame, :meth:`ProcessEvent` will
         need to be called on the associated document and view in case event handler
         functions are associated with these objects. 

         The normal order of event table searching is as follows:

         1. If the object is disabled (via a call to :meth:`~EvtHandler.SetEvtHandlerEnabled`) the function
            skips to step (6).
         2. If the object is a :class:`Window`, :meth:`ProcessEvent` is recursively called on the window's 
            :class:`Validator`. If this returns ``True``, the function exits.
         3. wxWidgets `SearchEventTable` is called for this event handler. If this fails, the
            base class table is tried, and so on until no more tables exist or an appropriate
            function was found, in which case the function exits.
         4. The search is applied down the entire chain of event handlers (usually the chain
            has a length of one). If this succeeds, the function exits.
         5. If the object is a :class:`Window` and the event is a :class:`CommandEvent`, :meth:`ProcessEvent` is
            recursively applied to the parent window's event handler. If this returns ``True``,
            the function exits.
         6. Finally, :meth:`ProcessEvent` is called on the :class:`App` object.
