|phoenix_title|  **wx.Window.ChildrenRepositioningGuard**
==========================================================================================================================================

Helper for ensuring :meth:`~wx.Window.ChildrenRepositioningGuard.EndRepositioningChildren`  is called correctly.          

This class wraps the calls to :meth:`~wx.Window.ChildrenRepositioningGuard.BeginRepositioningChildren`  and :meth:`~wx.Window.ChildrenRepositioningGuard.EndRepositioningChildren`  by performing the former in its constructor and the latter in its destructor if, and only if, the first call returned ``True``. This is the simplest way to call these methods and if this class is created as a local variable, it also ensures that :meth:`~wx.Window.ChildrenRepositioningGuard.EndRepositioningChildren`  is correctly called (or not) on scope exit, so its use instead of calling these methods manually is highly recommended.
