S2S is a stand alone application that allows developer to convert existing Swing GUI applications into SWT GUI. The program examines run-time structure of Swing GUI and generates appropriate java code.

Conversion Mapping
Swing	SWT
JRadioButton	Button SWT.RADIO
JCheckBoxButton	Button SWT.CHECK
JButton	Button SWT.PUSH
JToggleButton	Button SWT.TOGGLE
JLabel	Label
JSlider	Scale
JTextArea	Text SWT.MULTI
JEditorPane	StyledText
JPasswordField	Text
JTextField	Text
JList	List
JComboBox	Combo
JTree	Tree
JTable	Table, TableColumn, TableItem
JProgressBar	ProgressBar
JDesktopPane	CTabFolder
JInternalFrame	CTabItem
JPanel	Composite | Group
JTabbedPane	CTabFolder
JScrollPane	ScrolledComposite
JMenuBar	Menu SWT.BAR
JToolBar	ToolBar
JToolBar subcomponents	ToolItem SWT.RADIO |  SWT.CHECK | SWT.PUSH | SWT.SEPARATOR
JMenu	Menu
JCheckBoxMenuItem	MenuItem SWT.CHECK
JRadioButton	MenuItem SWT.RADIO
JMenuItem	MenuItem
FlowLayout	FillLayout | RowLayout
GridLayout	GridLayout
GridBagLayout:	GridLayout
CardLayout	StackLayout
BoxLayout	FillLayout | RowLayout
Other Layouts	null layout, Bounds property
BorderLayout	FormLayout
AbsoluteLayout	null layout, Bounds property

 

In addition, main properties of Swing components are examined and property set code is generated for SWT properties such as Alignment, Text, ToolTipText, Selection, Editable, Enabled, Icon, Image, DisabledImage, HotImage, Bounds, Minimum, Maximum, EchoChar and others.

Image (Icon) Handling:
If image path can be identified, it is copied and referenced direclty. If image path cannot be identified, screen capture on the image is performed, and the resulting jpeg is saved to generated folder and then referenced in generated SWT java code.

Other Components Handling:
If SWING2SWT encounters a component, which it cannot map to the appropriate SWT component, an SWT Label with appropriate message is used as a stub for the unhandled component.
