swt和awt之间的互调

SWT中嵌入awt/swing控件：

public static void main(String[] args) ...{
        final Display display = new Display();
        final Shell shell = new Shell(display,SWT.EMBEDDED);
        Frame frame = SWT_AWT.new_Frame(shell);
        
        frame.setLayout(new BorderLayout());
        frame.setBackground(Color.blue);
        frame.add(new JLabel("I'm swing label."),BorderLayout.NORTH);
        JButton btnClose=new JButton("close");
        btnClose.addActionListener(new ActionListener()...{
            public void actionPerformed(ActionEvent e) ...{
                display.syncExec(new Runnable()...{
                    public void run()...{
                        shell.close();
                    }
                });
            }
        });        
        frame.add(btnClose,BorderLayout.SOUTH);
        Panel panel = new Panel();
        panel.setBackground(Color.orange);
        frame.add(panel,BorderLayout.CENTER); 

        shell.setSize(400, 300);
        shell.open();
        while (!shell.isDisposed()) ...{
            while (!display.readAndDispatch()) ...{
                display.sleep();
            }
        }
        display.dispose();
    }

 

Eclipse视图效果：

    public void createPartControl(Composite parent) ...{
        Composite p=new Composite(parent,SWT.EMBEDDED);
        Frame frame = SWT_AWT.new_Frame(p);
        
        frame.setLayout(new BorderLayout());
        frame.setBackground(Color.blue);
        frame.add(new JLabel("I'm swing label."),BorderLayout.NORTH);
        JButton btnClose=new JButton("close");
        frame.add(btnClose,BorderLayout.SOUTH);
        Panel panel = new Panel();
        panel.setBackground(Color.orange);
        frame.add(panel,BorderLayout.CENTER); 
    }

 

swing/awt中使用swt

 

    public static void main(String[] args) ...{
        final JFrame frame = new JFrame();
        Canvas canvas = new Canvas();
        frame.getContentPane().add(canvas,BorderLayout.CENTER);
        frame.setVisible(true);

        Display display = new Display();
        final Shell shell = SWT_AWT.new_Shell(display,canvas);
        shell.setLayout(new FillLayout());
        Button button = new Button(shell,SWT.PUSH);
        button.setText("SWT Button");
        button.addSelectionListener(new SelectionListener()...{
            public void widgetDefaultSelected(SelectionEvent e) ...{
            }

            public void widgetSelected(SelectionEvent e) ...{
                SwingUtilities.invokeLater(new Runnable()...{
                    public void run()...{
                        frame.dispose();
                    }
                });
            }
            
        });
        frame.setSize(400,300);
        
        while (!shell.isDisposed()) ...{
          if (!display.readAndDispatch())...{
            display.sleep ();
          }
        }
        display.dispose();
    }

 

SWT的透明效果(对控件无效)

 

    public static void main(String[] args) ...{
        final Display display = new Display();
        final Shell shell = new Shell(display,SWT.NO_BACKGROUND);
        shell.addPaintListener(new PaintListener() ...{
            public void paintControl(PaintEvent e) ...{
                GC gc = e.gc;
                ImageData imageData = new ImageData("qd2.jpg");
                imageData.alpha=90;
                Image image = new Image(display, imageData);
                gc.drawImage(image,0,0);
            }
        });
        shell.setSize(400,300);
        shell.open();
        while (!shell.isDisposed()) ...{
          if (!display.readAndDispatch())...{
            display.sleep ();
          }
        }
        display.dispose();
    }
