Applets also improved with use: after a first applet is run, the JVM was already running and subsequent applets started quickly (the JVM will need to restart each time the browser starts afresh). JRE versions 1.5 and greater restarted the JVM when the browser navigates between pages, as a security measure which removed that performance gain.
Swing is a highly modular-based architecture, which allows for the "plugging" of various custom implementations of specified framework interfaces: Users can provide their own custom implementation(s) of these components to override the default implementations using Java's inheritance mechanism via LookAndFeel.
A general interface between Java and the native system, used for windowing, events, and layout managers. This API is at the core of Java GUI programming and is also used by Swing and Java 2D. It contains: The interface between the native windowing system and the Java application; The core of the GUI event subsystem; Several layout managers;
The "Java Foundation Classes" were later renamed "Swing", adding the capability for a pluggable look and feel of the widgets. This allowed Swing programs to maintain a platform-independent code base, but mimic the look of a native application. The release of JFC made IFC obsolete, and dropped interest for Microsoft's AFC.
Most of the system library is also written in Java. For instance, the Swing library paints the user interface and handles the events itself, eliminating many subtle differences between how different platforms handle components. The Java class libraries serve three purposes within the Java platform.
SWTSwing is a project to provide a Swing back end for SWT. In effect, SWT could be run using Swing native objects instead of, for example, GTK or Windows native objects. This would enable SWT to work on every platform that Swing supports. [21] Starting in 2006, there was an SWT-3.2 port to the programming language D called DWT. [22]
The word applet was first used in 1990 in PC Magazine. [2] However, the concept of an applet, or more broadly a small interpreted program downloaded and executed by the user, dates at least to RFC 5 (1969) by Jeff Rulifson, which described the Decode-Encode Language, which was designed to allow remote use of the oN-Line System over ARPANET, by downloading small programs to enhance the ...
A software widget is a relatively simple and easy-to-use software application or component made for one or more different software platforms.. A desk accessory or applet is an example of a simple, stand-alone user interface, in contrast with a more complex application such as a spreadsheet or word processor.
