Learn how to implement interface events in a class. See code examples and view additional available resources.
To implement event delegation, attach the event listener to a parent element and use the event.target property to determine if the event originated from the desired element. Here's an example of event delegation: document.querySelector('ul').addEventListener('click', function(event) { if (...
This section explains how to implement three kinds of window-related event handlers:WindowListener,WindowFocusListener, andWindowStateListener. All three listeners handleWindowEventobjects. The methods in all three event handlers are implemented by the abstractWindowAdapterclass. ...
From this map, you can pick out an event ‘flow’ that will give you aquick win: something you can implement easily, quickly, or for a big impact. It would also be helpful to make this the reference point for the future, allowing you to reuse events or even parts of the event flow...
Action listeners are probably the easiest — and most common — event handlers to implement. You implement an action listener to define what should be done when an user performs certain operation. An action event occurs, whenever an action is performed by the user. Examples: When the user clic...
However, in some cases you may have to provide custom behavior. One such case is shown in the topic How to implement interface events. Example The following example shows how to implement custom add and remove event accessors. Although you can substitute any code inside the accessors, we ...
To create a new event type, you must create a new class that inherits either from the top level EventType Class or from one of its subclasses, and then override certain methods as appropriate. The first two sections below describe the key members and methods of the top level EventType clas...
