<p>Propagates that a widget was enabled or disabled through children. </p>
<p>When enabling or disabling a widget, you usually also want to disable contained children.

<p>You may want to reimplement this method if they wish to render differently when a widget is disabled. The default implementation will propagate the signal to all children. </p>
