.. _ZDefaultWidgetManager:
ZDefaultWidgetManager
=====================
In dialogs there is often a default widget that can be activated even if focus is on another widget using :kbd:`Enter`.
This facet of the dialog window widget is used to coordinate this.
Implementations of this facet stores a pointer to the default widget and implement logic to determine if the
default widget is active and will receive :kbd:`Enter` events or if the focused widget will handle the :kbd:`Enter` key.
