This cluster contains all the common properties available for EiffelVision 2 [[Widgets|widgets]] and [[Items|items]] . Every EiffelVision 2 widget has the same set of properties inherited from EV_WIDGET, but many widgets also inherit additional properties, further refining the behavior of the widget.
The Properties cluster contains all the common properties available for EiffelVision 2 [[Widgets|widgets]] and [[Items|items]]. Every EiffelVision 2 widget has the same set of properties inherited from EV_WIDGET, but many widgets also inherit additional properties, further refining the behavior of the widget.
EV_WIDGET inherits the following properties:

** If an EiffelVision 2 component inherits [[ref:libraries/vision2/reference/ev_sensitive_chart|EV_SENSITIVE]] , it can be made to ignore events. <br/>
Use <eiffel>disable_sensitive</eiffel> to disable event handling, and <eiffel>enable_sensitive</eiffel> to restore event handling.
