.allowFocus

boolean

True if this label may receive direct input focus using the mouse, touch, or using UIComponent.requestFocus (cannot be changed after rendering this component), defaults to false.

.allowKeyboardFocus

boolean

True if this label may receive input focus using the keyboard and all other methods (cannot be changed after rendering this component), defaults to false.
