20. SWTworkbench.com SWT Disadvantages ● Lightweight ● Immature compared to Swing ● A few fewer platforms supported

21. SWTworkbench.com How does SWT relate to Swing? ● Swing's main strengths – Consistent look & feel across all platforms; attractive themes are available. – Sun-supported – (What else would you add?)

22. SWTworkbench.com How does SWT relate to Swing? ● SWT's main strengths – Native look and feel, because it is native. – Open source support

23. SWTworkbench.com How does SWT relate to Swing? ● Swing's main strengths – Consistent look & feel across all platforms; attractive themes are available. – Sun-supported. ● SWT's main strengths – Native look and feel, because it is native. – Open source support. These are complementary, not competitive strengths

24. SWTworkbench.com Why SWT? ● Web Services shift the emphasis on the client away from the web browser, back toward traditional GUI applications ● SWT strengthens Java's position in this market ● SWT provides features that compliment, rather than replace, Swing

25. SWTworkbench.com A Taste of SWT ● Hello, SWT public class HelloSWT { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); }

26. SWTworkbench.com A Taste of SWT ● Hello, SWT

27. SWTworkbench.com A Taste of SWT ● A simple SWT control public class HelloSWTControl extends Canvas implements PaintListener { public HelloSWTControl(Composite parent, int style) { super(parent, style); addPaintListener(this); } public void paintControl(PaintEvent e) { e.gc.drawText("Hello, world", 5, 5); }

28. SWTworkbench.com A Taste of SWT ● A closer look at the constructor public class HelloSWTControl extends Canvas implements PaintListener { public HelloSWTControl(Composite parent, int style) { super(parent, style); addPaintListener(this); } public void paintControl(PaintEvent e) { e.gc.drawText("Hello, world", 5, 5); }

29. SWTworkbench.com A Taste of SWT ● SWT constructors have 2 arguments: – The parent control ● SWT controls are added to their parents during construction, not by using an add( ) method – Style bits ● Some things you're used to seeing as properties of an object show up as style bits on the constructor ● This is the way the underlying O/S toolkits actually work – (SWT just wraps the underlying O/S's objects)

30. SWTworkbench.com A Taste of SWT ● Displaying the SWT control public class HelloSWT { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); }

31. SWTworkbench.com A Taste of SWT ● Displaying the SWT control public class HelloSWT { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); shell.setLayout(new FillLayout()); new HelloSWTControl(shell, SWT.NULL); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); }

32. SWTworkbench.com A Taste of SWT ● Displaying the SWT control

33. SWTworkbench.com A Taste of SWT ● Managing graphical resources: a more complex example

34. SWTworkbench.com A Taste of SWT ● Managing graphical resources public class Blotter extends Canvas implements PaintListener { public Blotter(Composite parent, int style) { super(parent, style); addPaintListener(this); } public void paintControl(PaintEvent e) { // Put our drawing code here }

39. SWTworkbench.com A Taste of SWT ● Managing graphical resources public void paintControl(PaintEvent e) { GC gc = e.gc; Color black = display.getSystemColor(SWT.COLOR_BLACK); Color gray = display.getSystemColor(SWT.COLOR_GRAY); Rectangle bounds = this.getBounds(); gc.setForeground(black); gc.drawLine(0, 0, 0, bounds.height); gc.setForeground(gray); gc.drawLine(1, 0, 1, bounds.height); //...and so on... }

40. SWTworkbench.com A Taste of SWT ● Managing graphical resources – This is all there is to creating this control! – Conclusion: ● If you don't construct a graphical resource, you do not have to dispose it ● You can get away with this an amazing amount of the time

100. SWTworkbench.com Summary ● SWT provides a fast, native user interface for rich client Java applications. ● SWT has taken two meanings depending on if a formal or informal context is being used: – Formal: SWT = Java-wrapped O/S widgets. – Informal: SWT+JFace all the way up to the entire Eclipse application framework. ● SWT and Swing have complementary (not competitive) strengths and weaknesses.
