About generating events from components
You can define events to be generated when the user interacts with a component. Most components support a primary event, a data change event, a gain focus event, and a lose focus event. For instance, you might want to generate a custom event when the user clicks a push button. To do this, specify the custom event name as the push button's primary event.
The table below describes the conditions under which each type of event is generated.
