AWT / Swing

AWT

Native implementation of few basic widgets

Swing

Emulation of more widgets

Features

java.applet

java.awt

java.awt.dnd

java.awt.event

java.awt.font

java.awt.geom

java.awt.image

java.awt.print

AWT

Swing

javax.swingjavax.swing.borderjavax.swing.filechooserjavax.swing.tablejavax.swing.textjavax.swing.treejavax.swing.undo


SWT – Overview

Concept

Uses native widgets => platform dependent parts

Emulation if native not available

Can be used without Eclipse!

Features

Drag‘n‘Drop

Events

Layout

Graphics

Print

Qt Jambi – Events

slider.addChangeListener(new ChangeListener() { public void stateChanged(ChangeEvent e) { spinner.setValue(slider.getValue()); }});spinner.addChangeListener(new ChangeListener() { public void stateChanged(ChangeEvent e) { slider.setValue((Integer)spinner.getValue()); }});

slider.valueChanged.connect(spinBox, "setValue(int)"); spinBox.valueChanged.connect(slider, "setValue(int)");


Licenses

AWT/Swing <= Java 6.0: Sun Java License

AWT/Swing >= Java 6.0: GPL

JFace/SWT: Eclipse Public License (EPL)

Fazit

Swing

Integriert in Java, gute Basis für Applikationen

„Fühlt“ sich nicht „echt“ an

Viele zusätzliche Bibliotheken und Widgets (swing-lab, JGoodies)

SWT/JFace

Native widgets und performance

Extrem viele standard Widgets, profitiert von Eclipse

Qt

Cool Stuff
