亚洲手机在线人成网站_ swt與awt/swing互嵌

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視圖效果：

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(對控件無(wú)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();

}
