Programming Graphical User Interfaces In Java An Introduction To Gui This document covers event and gui programming in java, detailing event handling, types of events, and the components of gui such as panels, frames, and layout managers. Key concepts in java event handling: event source: the object that generates an event, such as a button, a text field, or a window. event listener: an object that is interested in responding to an event generated by an event source.
Graphical User Interfaces In Java Graphical User Interfaces In Java In this chapter we will explore the creation of graphical user interfaces (guis).although console programs like the ones we have written in the preceding chapters are still very important,the majority of modern desk top applications have graphical user interfaces.supplement 3g introduced. Graphical objects can be manipulated by the user to trigger events. each graphical object can have 0, 1 or many events that can be triggered. when a container holds a number of components the components must be added to the container (later examples). Our purpose is to illustrate various aspects of event based programming. we use guis as the domain. java includes two packages for gui development, the abstract window toolkit (awt) and swing. our examples use swing. swing is the newer package and the more popular of the two.

A graphical user interface automatically keeps its display synchronized with the application's underlying data: a binding observes its list of dependencies for changes, and then updates itself automatically after a change has been detected. May i get more information about an event? the event received as an argument by the listeners’ methods is provided by java automatically. “asking” to that event object we can find out more things about what really happened. asking, as ever, is done by invoking methods of the event object. Gui controlled java application (applet) is event driven. events propagate notifications of state change or commands from a source object (a gui component) to one or more target objects (event listeners) via method invocation on listeners’ interfaces. Throughout this chapter, we will focus on designing and building guis that are easy for users to navigate. however, java’s gui libraries are so large that we will concentrate on only a handful of additional components, including containers, check boxes, radio buttons, and menus.
