Jython includes almost all of the modules in the standard Python programming language distribution, lacking only some of the modules implemented originally in C. For example, a user interface in Jython could be written with Swing, AWT or SWT. Jython compiles Python source code to Java bytecode (an intermediate language) either on demand or ...
The Abstract Window Toolkit (AWT) is Java's original platform-dependent windowing, graphics, and user-interface widget toolkit, preceding Swing. The AWT is part of the Java Foundation Classes (JFC) — the standard API for providing a graphical user interface (GUI) for a Java program. AWT is also the GUI toolkit for a number of Java ME profiles.
The Abstract Window Toolkit (AWT) is Sun Microsystems' original widget toolkit for Java applications. It typically uses another toolkit on each platform on which it runs. Swing is a richer widget toolkit supported since J2SE 1.2 as a replacement for AWT widgets. Swing is a lightweight toolkit, meaning it does not rely on native widgets.
Java applets were usually written in Java, but other languages such as Jython, JRuby, Pascal, [12] Scala, NetRexx, or Eiffel (via SmartEiffel) could be used as well. Java applets run at very fast speeds [citation needed] and until 2011, they were many times faster than JavaScript.
AWT existed before JFC. AWT was heavily criticized for being little more than a wrapper around the native graphical capabilities of the host platform. That meant that the standard widgets in the AWT relied on those capabilities of the native widgets, requiring the developer to also be aware of the differences between host platforms.
The event dispatching thread (EDT) is a background thread used in Java to process events from the Abstract Window Toolkit (AWT) graphical user interface event queue. It is an example of the generic concept of event-driven programming , that is popular in many other contexts than Java, for example, web browsers , or web servers .
In 2007, a lot of work was done to implement support for Java's two graphical APIs in GNU Classpath: AWT and Swing. Software support for AWT is still in development. "Once AWT support is working then Swing support can be considered. There is at least one free-software partial implementations of Swing that may be usable.".
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.
