An event is the equivalent to an action. Usually, a widget can generate a action, then trigger an events. Thus the events will be delivered to the relative event adapter and call the method which the developer created . In the tooling, developers have stored events within a widget event list. The user can select different events and add them to a widget according to their requirement, where each widget is related to different events.
The user usually
clicks this button to add arbitrary numbers to events. The plus button
is used to add events to a selected widget.
This is a delete
button. Its function is opposite to the add button. Once user find
there are some events which are redundant, the user can click it to
delete the events not needed.
This is an update
button. In situations where the user has added several events for
a widget, and the event scenario needs to change based on a new events
requirement. Thus user can modify the primitive events name, description
or event by clicking the update button.
This button is
used to adjust the order of events in the event list, by moving it
to the top of the list.
