<p>A helper class implementing TAB navigation among the window children. </p>
<p>This class contains the functionality needed to correctly implement TAB navigation among the children of the window. Its exact contents is not important and is intentionally not documented as the only way to use this class is to inherit from it instead of inheriting from the usual base class directly. For example, if some class needs to inherit from <a class="el" href="classwx_control.html" title="This is the base class for a control or "widget".">wxControl</a> but contains multiple sub-windows and needs to support keyboard navigation, it is enough to declare it in the following way: </p>

<p>Default constructor. </p>
<p>This class provides only the default constructor as it's not possible, in general, to provide all the constructors of the real base class BaseWindowClass.</p>
<p>This is however not usually a problem for wxWindow-derived classes as, by convention, they always define a Create() method such that calling it on an object initialized using the default constructor is equivalent to using a non-default constructor directly. So the classes inheriting from wxNavigationEnabled<W> should simply call W::Create() in their constructors. </p>
