- The document discusses several Java GUI toolkits: Swing, SWT, and Qt Jambi. It provides a history of each and compares their features. - Swing emulates widgets while SWT uses native widgets, making it more platform dependent but with better performance. SWT is widely used in Eclipse. - Qt Jambi is based on the Qt framework and provides features like signals/slots, stylesheets, multimedia support, and more. It can integrate with both AWT/Swing and native widgets.

8. 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 javax.swing javax.swing.border javax.swing.filechooser javax.swing.table javax.swing.text javax.swing.tree javax.swing.undo

9. 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

10. JFace Concept Based on SWT MVC everywhere A lot of additional widgets Features Actions Wizards Resources Text Viewers Operation Preferences Window Data bindings

11. Qt Jambi Ressource Management Signal & Slots Layout Management Style Sheets Qt Designer / Linguist Webkit Multimedia (Phonon) XML JDBC Qt Concurrent AWT/SWT Bridges Qt Jambi Generator http://www.qtsoftware.com/files/pdf/qt-jambi-4.4-whitepaper

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)");

15. 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
