Each Component's event handler can react to an event in any of the following ways:
- By ignoring the event and allowing it to be passed up the Component hierarchy. This is what the default Component implementation does. For example, since the TextField class and its TextComponent superclass implement no event handlers, TextFields get the default Component implementation. So when a TextField receives an Event, it ignores it and allows its container to handle it.
- By modifying the Event instance before it goes further up the hierarchy. For example, a TextField subclass that displays all letters in uppercase might react to the keypress of a lowercase letter by changing the Event to contain the uppercase version of the letter.
- By reacting in some other way to the event. For example, a TextField subclass (or a TextField's container) could react to a Return keypress by calling a method that processes the text field's contents.
- By intercepting the event, stopping it from being processed further. For example, if an invalid character is entered in a text field, an event handler could simply stop the resulting Event from propagating upward. As a result, the platform-dependent implementation of the text field would never see the event.
From a Component's view, the AWT event-handling system is more like an event-filtering system. Platform-dependent code generates an event, but Components get a chance to modify, react to, or intercept the event before the platform-dependent code fully processes the event.

Difference between fault tree analysis and event tree analysis?
Difference between fault tree and event tree: 1) Fault trees lay out relationships among event whereas event trees lay out sequences of events linked by conditional probabilities. 2) Event trees can handle better notions of continuity (logical, temporal, and physical), whereas fault trees are most powerful in identifying and simplifying failure scenarios.
What is an event counter?
An event counter is a variable that starts off set to zero and is incremented at a certain point in code which is passed when something (the event) is occurring. For example, if you want an event counter to determine how many times the user responds to the question "what was the student's grade" with the answer "100", then within the existing loop to handle data entry, you could simply add something along the lines of (if grade equals to 100 then event_counter = event_counter + 1) and there you have an event counter.
What do you mean by event in dotnet?
An "event" in .Net is an implementation of the Observer design pattern. When you declare that one of your classes has an event, you declare the name of the event, and the arguments that the event will pass. Then, your other classes can "Observe" when this event happens, and handle the event when it is "Fired".For example, the Button windows control has a "Click" event. You can then write code that watches for those clicks, and runs when it happens.An event in C# is a way for a class to provide notifications to clients of that class when some interesting thing happens to an object. The most familiar use for events is in graphical user interfaces; typically, the classes that represent controls in the interface have events that are notified when the user does something to the control (for example, click a button).
